2 Project description

-
-

-I had pair of good compact stereo speakers lying uselessly around as -well as secondhand TDA2030 Chinese knockoff audio amplifier chips. -Also I wanted to test modular construction approach: motherboard with -shared bus and functionality realized via pluggable modules. So I -built stereo speaker: -

- - -
-

make.png -

-
- -

-Indicator on the front panel shows available power within the -system. Ideally it should be at the maximum. It drops when batteries -run empty or when consumed power (too loud music) is greater than -onboard power supply or batteries can handle. It has on/off switch and -stereo audio input. Audio input impedance is about 100 ohms. -

- - -
-

make,%20side.png -

-
- -

-Idea for the holes on the top and smaller ones on the bottom back is -to enable air flow for passive cooling. -

- - -
-

make,%20back.png -

-
- -

-Entire construction is made of parts, no larger than -120x120x120mm. Maximum for my printer. -

-
-
- -
-

3 Battery holder

-
-

-Device is powered by 4 times AA NiMH batteries (1.2V each). -

- - -
-

-
- -

-I happened to have AA battery adapters lying around with different -bottom hole configurations. Therefore this weird hole design: -

4 20V up-step module

-
-

-Battery pack voltage is routed through main on/off switch on the front -panel, and then it goes to the 20V up-step module. -

- - -
-

schematic.png -

-
- -

-It uses ready made upstep module, but adds extra voltage filtering via -inductor and capacitors. -

- - -
-

-
-
-
- -
-

5 Main board

-
-

-Voltage upstep above sits on top of main board (motherboard). It has -uniform central bus that spans all connectors. -

- - -
-

-First row of the main board is special IO terminal (for connecting -speakers, front panel, etc..) -

- - -
-

-Remaining rows are for connecting boards: -

6 Mono audio amplifier module

-
-

-Design uses scavenged secondhand Chinese TDA2030 audio amp -clones. Each chip is mono audio amplifier. Therefore 2 almost -identical audio amp modules had to be built, one for left speaker, one -for right. -

- - -
-

schematic.png -

-
- -

-I like to build on top of prototype PCBs. Gives results much faster -for one-off projects. Before soldering, I solve component layout on -paper: -

8 Front panel

-
-

-Initial idea was really simple panel: -

-
    -
  • on/off switch -
    • -
  • system power indicator -
    • -
  • stereo audio input -
    • -
- -

-But, since I'm using "agile" approach, during load-testing, it become -clear that active fan based cooling would be nice (when playing loud -music). I found tiny cooler fan that needs 5 volts to operate. Also I -need to power backlight for power indicator. For both of these cases, -I decided to add another voltage up-step module (target voltage output -set to 6V). This time directly on the front panel. -

9 Extra capacitors

-
-

-Another thing that become clear during load-testing: output -power/volume can be further enhanced by adding high power capacitors -to even out load on primary 20V up-step module. -

  • Instead of using undersized heatsinks on the audio amplifiers and -need for active cooling as a consequence, it would be better to try -to mount audio amplifier chip on top of speaker metallic body. It -would provide plenty of cooling and reduces power losses within -cable, since amplifier would be as close to the speaker as possible. -
    • - -
  • I used agile design. That is, implemented functionality ad-hoc. If I -had done design in advance, then I could have had smarter connector -layout between main board and front panel. That is: Instead of -multiple smaller cables, one wide (multi connector) cable. -
    • - -
  • Screw holes are too close to the edges on the front panel. -
    • - -
  • It would be better if screw heads were slightly buried within -construction body. -

-Overall, it was good learning experience and I was able to test -various ideas on it. Will add cooler later :) -

+
+ +

+Very old people often have problems with mental abilities, touch and +vision. When the phone rings it is real issue to figure out what +button to press and hit the right one to pick up the call. It is easy +to end up in random phone menus instead that are incomprehensible for +the elderly. +

+ +

+Here is solution for the problem in the form of 3D printed case and +extra add-on button that is glued to the original dial/receive key of +the phone. All other buttons are rendered inaccessible on purpose. +

+ +

+For extra clarity, this one important button: +

+
    +
  • Is painted red. +
    • +
  • Has exaggerated surface and relief raising above main case surface. +
    • +
  • Has big white circle around it (I used airbrush with stencil to +paint the circle). +

2.1 Original Nokia 105 (2019)

+
+ +
+

1.png +

+
+ +

+Nokia 105 (2019) allows receiving calls and dialing back the most +recent call using single dial button (cannot hang up) though. Receiver +of the call on the other end has to hang up. Prepaid SIM card is used, +to avoid accidental/unintended charges for whatever reason. +

+
+
+ +
+

2.2 Enlarged dial button

+As regular user of this tool, I got annoyed that original cell +batteries run empty so fast and I have to worry about finding +replacements. +

+ + +
+

make,%202.png +

+
+ +

+So I added AAA battery compartment to the bottom, and now I can use +relatively large capacity and rechargeable NiMH batteries. +

+

+ +

+The new problem I got is, how can I store and carry this thing +around. So special case is designed. +

+ + +

+
+ +

+And special cover. Design utilizes 3mm x 2mm thick neodymium magnets +to keep cover magnetically attached to storage box. +

+ + +
+

+
+ +

+My printer can print only 120x120x120 mm objects. So only the most +delicate part is protected. There is some empty space in the box +because of geometry of the tool. It can be used as small storage +compartments for something. +

+I am a big fan of stackable bins organizer. I find 2x2 bins with 21mm +height are particularly good for storing rolls of wire. Also electric +handheld screwdriver is good for twisting wire onto the +roll. Therefore I designed rolls that have standard hexagonal hole on +the bottom (for screwdriver compatibility): +

+ + +
+

+and 20mm total roll height, to be used with stackable bins +organizer. Rolls are made from body and cover: +

Battery charger and dual power supply unit

+ +
+

1 General

+
+ +
+
+ +
+

2 Project description

+
+

+I needed dual voltage power supply for my lab that runs on mains +electricity (wall power) and slowly charges attached 12V Lead-Acid +battery. Lead-acid battery in turn provides high current when needed +as well as power in portable situations or when mains electricity is +not available. +

+ + +
+

make.png +

+
+ +

+Power supply provides about 13 Volts and 5 Volts simultaneously. +

+ +

+!!!WARNING!!! I use USB-A connectors for power output, but IT IS NOT +COMPATIBLE WITH USB DEVICES AND POSSIBLY WITH EXISTING USB CABLES. +

+ +

+Normal USB devices and cables should not be plugged in! It would +damage device/cable and likely power supply. +

+ +

+I found USB-A connectors to be easily available, cheap, reliable and +functional, so I re-purposed connector for my own needs but I'm using +totally incompatible electrical wiring. +

+ + +
+

USB%20hack.png +

+
+ +

+As seen, it has dual voltage output. Additionally one wire is +dedicated to data transmission and can be used with 1-wire +protocol. Power supply simply passively links all data wires together +but does not participate in communication. +

+ +

+Power supply uses 3D printed body with lots of holes, for fanless +cooling. +

+ + +
+

body,%201.png +

+
+ +

+Various modules are realized on top of prototype PCBs that slide into +dedicated rails within the body. +

+ + +
+

+When cover is closed, it blocks PCB movement: +

+
+ +

+There is still some empty space inside, so why not add dummy cover on +top that can be replaced later with add-on functionality/expansion +board/terminal :) +

3 Transformer and AC to DC converter

+
+

+This is where high voltage from mains electricity enters the system. +

+ +

+Schematic: +schematic.png +

+ +

+For safety I kept high voltage section as minimal as possible. That +is, wall plug runs straight into transformer. Also I used UV hardening +glue for extra safety and isolation on PCB. +

+ +

+Power on/off switch operates on already reduced voltage of about 30 +volts. Power switch is located on indicator panel. +

+ + +
+

make,%201.png +

+
+ +

+DC current of about 30 volts is then routed to Main board. +

+ + +
+

make,%202.png +

+
+ +

+Single sided prototype PCB is used. +

+
+
+ +
+

4 Main board

+
+

+This is logically main board because it appears to be central hub that +connects all components. It also houses 2 adjustable DC-DC Step Down +voltage converters. +

+ + +
+

main%20board,%201.png +

+
+ +

+High-level schematic of entire device: +schematic.png +

+ +

+As seen from schematic, ~30 volts DC from transformer board is routed +into first step-down converter that reduces it to about 15V. Reduced +voltage is then directed to Current limiter circuit. Current limiter +loses about 2 volts. Now we have current and voltage limited power at +about 13 volts. This power is used to charge connected 12V Lead-Acid +battery. Also the same power is routed to connector terminal to be +consumed by connected devices. +

+ +

+As seen from this schematic, device is not meant to provide high +current for long periods of time. Instead it gets comparatively +limited current to charge the battery and feed devices with low +current requirements. Occasional current spikes are backed up by +battery that stays in use-changing mode. +

+ +

+Also about 13V output voltage is approximate and depends on connected +battery charge level. +

+ +

+Second Step-Down converter reduces voltage even further to quite +precisely 5V DC. This resulting voltage is also routed to connector +terminal. +

+ +

+Both 13V and 5V lines are also routed to indicator panel for +monitoring. +

+ +

+There is single on/off switch. In off position, it disconnects battery +and transformer from the system effectively powering everything down. +

+ +

+On schematic above, some wires are annotated with numbers from 1 +to 13. This corresponds to output pins on the board. +

+ + +
+

5 Current limiter

+
+

+Schematic: +schematic.png +

+ +

+Simple LM317 based current limiter is used. I used 4.7 ohm +resistor. It provides about 265 milliamps of current. See calculator. +

+ + +
+

current%20limiter,%201.png +

+
+ +

+Thermal paste below and UV hardening glue on top is used to attach +LM317 to the heatsink. There is also jumper-like solution on top +right. This is handy to attach multimeter tap to verify/monitor +current during initial device calibration. +

+ +

+If attached battery is really empty, significant voltage drop can +occur in LM317. Heatsink is needed to dissipate that power. +

+ + +
+

+
+ +

+Note: resistor gets hot too. +

+
+
+ +
+

6 Indicator panel

7 Connector terminal

+
+

+Schematic: +schematic.png +

+ +

+As seen above, most of the USB connectors are used to deliver dual +power output and 1-wire data connectivity, except one on the bottom +right. This is used to attach 12V battery. Some capacitors are thrown +in as well to stabilize against smaller current spikes. +

+ +

+Electrically schematic is realized using smaller prototype PCBs. +

+ + +
+

make,%201.png +

+
+ + +

+Those PCBs are wired to central small PCB that acts as a hub: +

+ + +
+

make,%202.png +

+
+ +

+PCBs are held together by being sandwiched between front panel: +

+ + +
+

front%20panel.png +

+
+ +

+and smaller back-end plate: +

+ + +
+

8 Calibration

+
+

+Since device uses adjustable step-down modules, these need to be +calibrated to provide correct output voltage. It is important that +battery receives proper charging voltage otherwise either no charging +occurs or battery starts gassing out and gets destroyed. +

+ +

+Happy building! :) +

It also houses 2 [[https://www.amazon.de/gp/product/B072MQYJ93/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1][adjustable DC-DC Step Down +voltage converters]]. + +[[file:main%20board/main%20board,%201.png]] + +High-level schematic of entire device: +[[file:main%20board/schematic.png]] + +As seen from schematic, ~30 volts DC from transformer board is routed +into first step-down converter that reduces it to about 15V. Reduced +voltage is then directed to [[id:afc22d23-9bc4-421c-9cac-e0ce34bd36bc][Current limiter circuit]]. Current limiter +loses about 2 volts. Now we have current and voltage limited power at +about 13 volts. This power is used to charge connected 12V Lead-Acid +battery. Also the same power is routed to [[id:e33940bd-652f-4ec0-b53b-1c03e16941c8][connector terminal]] to be +consumed by connected devices. + +As seen from this schematic, device is not meant to provide high +current for long periods of time. Instead it gets comparatively +limited current to charge the battery and feed devices with low +current requirements. Occasional current spikes are backed up by +battery that stays in use-changing mode. + +Also about 13V output voltage is approximate and depends on connected +battery charge level. + +Second Step-Down converter reduces voltage even further to quite +precisely 5V DC. This resulting voltage is also routed to [[id:e33940bd-652f-4ec0-b53b-1c03e16941c8][connector +terminal]]. + +Both 13V and 5V lines are also routed to [[id:c9a69490-f920-4a31-b32e-b101bfc3d01b][indicator panel]] for +monitoring. + +There is single on/off switch. In off position, it disconnects battery +and transformer from the system effectively powering everything down. + +On schematic above, some wires are annotated with numbers from 1 +to 13. This corresponds to output pins on the board. + +[[file:main%20board/main%20board,%202.png]] +* Current limiter +:PROPERTIES: +:ID: afc22d23-9bc4-421c-9cac-e0ce34bd36bc +:END: + +Schematic: +[[file:current%20limiter/schematic.png]] + +Simple LM317 based current limiter is used. I used 4.7 ohm +resistor. It provides about 265 milliamps of current. See [[http://www.reuk.co.uk/wordpress/electric-circuit/lm317-current-calculator/][calculator]]. + +[[file:current%20limiter/current%20limiter,%201.png]] + +Thermal paste below and UV hardening glue on top is used to attach +LM317 to the heatsink. There is also jumper-like solution on top +right. This is handy to attach multimeter tap to verify/monitor +current during initial device calibration. + +If attached battery is really empty, significant voltage drop can +occur in LM317.

Portable stereo speaker

+

2 Project description

+
+

+I had pair of good compact stereo speakers lying uselessly around as +well as secondhand TDA2030 Chinese knockoff audio amplifier chips. +Also I wanted to test modular construction approach: motherboard with +shared bus and functionality realized via pluggable modules. So I +built stereo speaker: +

+ + +
+

make.png +

+
+ +

+Indicator on the front panel shows available power within the +system. Ideally it should be at the maximum. It drops when batteries +run empty or when consumed power (too loud music) is greater than +onboard power supply or batteries can handle. It has on/off switch and +stereo audio input. Audio input impedance is about 100 ohms. +

+ + +
+

make,%20side.png +

+
+ +

+Idea for the holes on the top and smaller ones on the bottom back is +to enable air flow for passive cooling. +

+ + +
+

make,%20back.png +

+
+ +

+Entire construction is made of parts, no larger than +120x120x120mm. Maximum for my printer. +

+
+
+ +
+

3 Battery holder

+
+

+Device is powered by 4 times AA NiMH batteries (1.2V each). +

+ + +
+

schematic.png +

+
+ +

+I happened to have AA battery adapters lying around with different +bottom hole configurations. Therefore this weird hole design: +

4 20V up-step module

+
+

+Battery pack voltage is routed through main on/off switch on the front +panel, and then it goes to the 20V up-step module. +

+ + +
+

schematic.png +

+
+ +

+It uses ready made upstep module, but adds extra voltage filtering via +inductor and capacitors. +

+ + +
+

make.png +

+
+
+
+ +
+

5 Main board

+
+

+Voltage upstep above sits on top of main board (motherboard). It has +uniform central bus that spans all connectors. +

+ + +
+

internal%20bus.png +

+
+ + +
+

bus%20on%20the%20bottom,%202.png +

+
+ +

+First row of the main board is special IO terminal (for connecting +speakers, front panel, etc..) +

+ + +
+

IO%20terminal.png +

+
+ +

+Remaining rows are for connecting boards: +

+ + +
+

+ +

+To provide structural support, main board is attached to frame: +

+ + +
+

+And boards plugged into main board are fixed at the top, using clip: +

6 Mono audio amplifier module

+
+

+Design uses scavenged secondhand Chinese TDA2030 audio amp +clones. Each chip is mono audio amplifier. Therefore 2 almost +identical audio amp modules had to be built, one for left speaker, one +for right. +

+ + +
+

schematic.png +

+
+ +

+I like to build on top of prototype PCBs. Gives results much faster +for one-off projects. Before soldering, I solve component layout on +paper: +

8 Front panel

+
+

+Initial idea was really simple panel: +

+
    +
  • on/off switch +
    • +
  • system power indicator +
    • +
  • stereo audio input +
    • +
+ +

+But, since I'm using "agile" approach, during load-testing, it become +clear that active fan based cooling would be nice (when playing loud +music). I found tiny cooler fan that needs 5 volts to operate. Also I +need to power backlight for power indicator. For both of these cases, +I decided to add another voltage up-step module (target voltage output +set to 6V). This time directly on the front panel. +

+ + +
+

+Another thing that become clear during load-testing: output +power/volume can be further enhanced by adding high power capacitors +to even out load on primary 20V up-step module. +

11 Conclusions / TODO

+
+

+These things could be done better: +

+ +
    +
  • Instead of using undersized heatsinks on the audio amplifiers and +need for active cooling as a consequence, it would be better to try +to mount audio amplifier chip on top of speaker metallic body. It +would provide plenty of cooling and reduces power losses within +cable, since amplifier would be as close to the speaker as possible. +
    • + +
  • I used agile design. That is, implemented functionality ad-hoc. If I +had done design in advance, then I could have had smarter connector +layout between main board and front panel. That is: Instead of +multiple smaller cables, one wide (multi connector) cable. +
    • + +
  • Screw holes are too close to the edges on the front panel. +
    • + +
  • It would be better if screw heads were slightly buried within +construction body. +
    • +
+ + +

+Overall, it was good learning experience and I was able to test +various ideas on it. Will add cooler later :) +

2 Project description

+
+

+I needed a way to experimentally find resistance that works best in +certain circuits. Usual potentiometers could not handle required power +dissipation and were not precise enough. +

+ +

+Solution is to build adjustable resistor: +

+ + +
+

make.png +

+
+ +

+Logically there is series of resistors that increase in resistance in +the power of 2: 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512. Each +resistor can be enabled or disabled by a switch. This makes entire +range of 0 – 1023.5 ohms available with the 0.5 ohms precision. +

+ +

+ +

+Here is front panel for switches: +front%20panel.png +

+ + +

+Sometimes I would like to use lightbulbs with various parameters as +test load/indicator. Current device has 4 of them included. +

+Simple rechargeable Ni-MH battery tester. The problem with those +batteries is: right after you take them out of charger, voltage level +at their terminals is good. But some old batteries will get +empty/discharged way too quickly under normal load. This device is +intended to discover old batteries with reduced capacity. +

+ +

+Freshly charged batteries are tested under high load for short time by +shorting battery + and - terminals using 5 ohm power resistor +(R1). Simultaneously battery voltage is being measured while under +load. +

+ + +
+

electrical%20schematic.png +

+
+ +

+I use vintage analog voltmeter. Instead of power resistor I use +Nichrome resistance wire. Test/measurement button should not be +pressed for long because power resistor gets hot quickly and battery +is being quickly depleted during measurement. +

2 Project description

-
-

-I needed dual voltage power supply for my lab that runs on mains -electricity (wall power) and slowly charges attached 12V Lead-Acid -battery. Lead-acid battery in turn provides high current when needed -as well as power in portable situations or when mains electricity is -not available. -

- - -
-

make.png -

-
- -

-Power supply provides about 13 Volts and 5 Volts simultaneously. -

- -

-!!!WARNING!!! I use USB-A connectors for power output, but IT IS NOT -COMPATIBLE WITH USB DEVICES AND POSSIBLY WITH EXISTING USB CABLES. -

- -

-Normal USB devices and cables should not be plugged in! It would -damage device/cable and likely power supply. -

- -

-I found USB-A connectors to be easily available, cheap, reliable and -functional, so I re-purposed connector for my own needs but I'm using -totally incompatible electrical wiring. -

- - -
-

USB%20hack.png -

-
- -

-As seen, it has dual voltage output. Additionally one wire is -dedicated to data transmission and can be used with 1-wire -protocol. Power supply simply passively links all data wires together -but does not participate in communication. -

- -

-Power supply uses 3D printed body with lots of holes, for fanless -cooling. -

- - -
-

body,%201.png -

-
- -

-Various modules are realized on top of prototype PCBs that slide into -dedicated rails within the body. -

-There is still some empty space inside, so why not add dummy cover on -top that can be replaced later with add-on functionality/expansion -board/terminal :) -

3 Transformer and AC to DC converter

-
-

-This is where high voltage from mains electricity enters the system. -

- -

-Schematic: -schematic.png -

- -

-For safety I kept high voltage section as minimal as possible. That -is, wall plug runs straight into transformer. Also I used UV hardening -glue for extra safety and isolation on PCB. -

- -

-Power on/off switch operates on already reduced voltage of about 30 -volts. Power switch is located on indicator panel. -

- - -
-

make,%201.png -

-
- -

-DC current of about 30 volts is then routed to Main board. -

- - -
-

make,%202.png -

-
- -

-Single sided prototype PCB is used. -

-
-
- -
-

4 Main board

-
-

-This is logically main board because it appears to be central hub that -connects all components. It also houses 2 adjustable DC-DC Step Down -voltage converters. -

- - -
-

main%20board,%201.png -

-
- -

-High-level schematic of entire device: -schematic.png -

- -

-As seen from schematic, ~30 volts DC from transformer board is routed -into first step-down converter that reduces it to about 15V. Reduced -voltage is then directed to Current limiter circuit. Current limiter -loses about 2 volts. Now we have current and voltage limited power at -about 13 volts. This power is used to charge connected 12V Lead-Acid -battery. Also the same power is routed to connector terminal to be -consumed by connected devices. -

- -

-As seen from this schematic, device is not meant to provide high -current for long periods of time. Instead it gets comparatively -limited current to charge the battery and feed devices with low -current requirements. Occasional current spikes are backed up by -battery that stays in use-changing mode. -

- -

-Also about 13V output voltage is approximate and depends on connected -battery charge level. -

- -

-Second Step-Down converter reduces voltage even further to quite -precisely 5V DC. This resulting voltage is also routed to connector -terminal. -

- -

-Both 13V and 5V lines are also routed to indicator panel for -monitoring. -

- -

-There is single on/off switch. In off position, it disconnects battery -and transformer from the system effectively powering everything down. -

- -

-On schematic above, some wires are annotated with numbers from 1 -to 13. This corresponds to output pins on the board. -

5 Current limiter

-
-

-Schematic: -schematic.png -

- -

-Simple LM317 based current limiter is used. I used 4.7 ohm -resistor. It provides about 265 milliamps of current. See calculator. -

- - -
-

current%20limiter,%201.png -

-
- -

-Thermal paste below and UV hardening glue on top is used to attach -LM317 to the heatsink. There is also jumper-like solution on top -right. This is handy to attach multimeter tap to verify/monitor -current during initial device calibration. -

- -

-If attached battery is really empty, significant voltage drop can -occur in LM317. Heatsink is needed to dissipate that power. -

- - -
-

-Note: resistor gets hot too. -

6 Indicator panel

7 Connector terminal

-
-

-Schematic: -schematic.png -

- -

-As seen above, most of the USB connectors are used to deliver dual -power output and 1-wire data connectivity, except one on the bottom -right. This is used to attach 12V battery. Some capacitors are thrown -in as well to stabilize against smaller current spikes. -

- -

-Electrically schematic is realized using smaller prototype PCBs. -

- - -
-

make,%201.png -

-
- - -

-Those PCBs are wired to central small PCB that acts as a hub: -

- - -
-

make,%202.png -

-
- -

-PCBs are held together by being sandwiched between front panel: -

- - -
-

-
- -

-and smaller back-end plate: -

8 Calibration

-
-

-Since device uses adjustable step-down modules, these need to be -calibrated to provide correct output voltage. It is important that -battery receives proper charging voltage otherwise either no charging -occurs or battery starts gassing out and gets destroyed. -

-Happy building! :) -

Reduced -voltage is then directed to [[id:afc22d23-9bc4-421c-9cac-e0ce34bd36bc][Current limiter circuit]]. Current limiter -loses about 2 volts. Now we have current and voltage limited power at -about 13 volts. This power is used to charge connected 12V Lead-Acid -battery. Also the same power is routed to [[id:e33940bd-652f-4ec0-b53b-1c03e16941c8][connector terminal]] to be -consumed by connected devices. - -As seen from this schematic, device is not meant to provide high -current for long periods of time. Instead it gets comparatively -limited current to charge the battery and feed devices with low -current requirements. Occasional current spikes are backed up by -battery that stays in use-changing mode. - -Also about 13V output voltage is approximate and depends on connected -battery charge level. - -Second Step-Down converter reduces voltage even further to quite -precisely 5V DC. This resulting voltage is also routed to [[id:e33940bd-652f-4ec0-b53b-1c03e16941c8][connector -terminal]]. - -Both 13V and 5V lines are also routed to [[id:c9a69490-f920-4a31-b32e-b101bfc3d01b][indicator panel]] for -monitoring. - -There is single on/off switch. In off position, it disconnects battery -and transformer from the system effectively powering everything down. - -On schematic above, some wires are annotated with numbers from 1 -to 13.

2 Project description

-
-

-I needed a way to experimentally find resistance that works best in -certain circuits. Usual potentiometers could not handle required power -dissipation and were not precise enough. -

- -

-Solution is to build adjustable resistor: -

- - -
-

make.png -

-
- -

-Logically there is series of resistors that increase in resistance in -the power of 2: 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512. Each -resistor can be enabled or disabled by a switch. This makes entire -range of 0 – 1023.5 ohms available with the 0.5 ohms precision. -

-Sometimes I would like to use lightbulbs with various parameters as -test load/indicator. Current device has 4 of them included. -

-Simple rechargeable Ni-MH battery tester. The problem with those -batteries is: right after you take them out of charger, voltage level -at their terminals is good. But some old batteries will get -empty/discharged way too quickly under normal load. This device is -intended to discover old batteries with reduced capacity. -

- -

-Freshly charged batteries are tested under high load for short time by -shorting battery + and - terminals using 5 ohm power resistor -(R1). Simultaneously battery voltage is being measured while under -load. -

-I use vintage analog voltmeter. Instead of power resistor I use -Nichrome resistance wire. Test/measurement button should not be -pressed for long because power resistor gets hot quickly and battery -is being quickly depleted during measurement. -
