++ DISCLAIMER: I DO ELECTRONICS AND 3D DESIGN SOLELY AS A HOBBY. THERE
+ COULD BE ERRORS THAT CAN RESULT IN ALL KINDS OF DAMAGE. USE THESE
+ DESIGNS AT YOUR OWN RISK.
+
+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:
+
+#+attr_html: :class responsive-img
+[[file: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.
+
+Schematic:
+#+attr_html: :class responsive-img
+[[file:schematic.png]]
+
+Here is front panel for switches:

+[[file:front%20panel.png]]
+
+Download:
++ [[file:front%20panel.FCStd][FreeCAD project]]
++ [[file:front%20panel.stl][STL file]]
+
+Sometimes I would like to use lightbulbs with various parameters as
+test load/indicator. Current device has 4 of them included.
+
+Here is front panel for light bulbs:

++ DISCLAIMER: I DO ELECTRONICS AND 3D DESIGN SOLELY AS A HOBBY. THERE

+ DESIGNS AT YOUR OWN RISK.
+
+*Warning!* Here I describe a hack that I personally found useful for
+my own needs. But it is dangerous. Not to be replicated unless you
+know that you are doing.
+
+#+attr_html: :class responsive-img
+[[file:make.png]]
+
+I needed a way to power various devices I build.
+
+Requirements:
+
+- Reliable.
+- Cheap.
+- Easy to use.
+- Popular and highly available.
+- Ability to draw significant current directly from 12V cheap, popular
+ and powerful lead-acid battery (optionally off-grid). Useful for
+ powerful electric motors, heaters, soldering irons, radio
+ transmitters, etc.
+- Ability to draw limited but stabilized 5V power. Good for digital
+ circuits.
+- Ability to have limited and simple 1-wire digital communication.
+
+USB Type A connectors are best match that I found.
+
+The main problem is, I like USB connectors but I want to use different
+and incompatible electrical layout with them.
+
+*Connecting proper USB power supplies, devices and even cables to the
+ones that use alternative electrical layout would do damage!!!*
+
+To avoid accidental mismatches, I mark all connectors/cables and devices that
+use alternative wiring with [[file:stickers.png][printed, laminated warning stickers]].
+
+Alternative wiring schematic:
+#+attr_html: :class responsive-img
+[[file:schematic.png]]
+
+- Outer shell is ground.
+- 2 central pins are re-purposed to deliver +12V and high power.
+- 1 pin is for limited power +5V.
+- 1 pin for 1-Wire data.
+
+Example warning marking on device to indicate that alternative USB
+layout is used here:

+
+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.
+
+#+attr_html: :class responsive-img
+[[file: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.

+
++ PS: While this device is interesting to build, still you can just
+ use ordinary ammeter that can handle battery generated current.

+
+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:
+
+#+attr_html: :class responsive-img
+[[file: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.
+
+#+attr_html: :class responsive-img
+[[file: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.
+
+#+attr_html: :class responsive-img
+[[file:make,%20back.png]]
+
+Entire construction is made of parts, no larger than
+120x120x120mm. Maximum for my printer.

+Initial idea was really simple panel:

++ 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.

+
+Improvement ideas:
+
++ 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.
+
++ Add possibility to power device from USB socket in addition to
+ batteries.
+
++ Front panel:
+ + Use digital voltage indicator to gauge remaining battery power.
+
+ + Add possibility to have multiple inputs.
+
+ + It would be better if screw heads were slightly buried within
+ construction body.
+
+ + Screw holes are too close to the edges on the front panel.

-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.

-* Overview
-
-+ DISCLAIMER: I DO ELECTRONICS AND 3D DESIGN SOLELY AS A HOBBY. THERE
- COULD BE ERRORS THAT CAN RESULT IN ALL KINDS OF DAMAGE. USE THESE
- DESIGNS AT YOUR OWN RISK.
-
-*Warning!* Here I describe a hack that I personally found useful for
-my own needs. But it is dangerous. Not to be replicated unless you
-know that you are doing.
-
-#+attr_html: :class responsive-img
-[[file:make.png]]
-
-I needed a way to power various devices I build.
-
-Requirements:
-
-- Reliable.
-- Cheap.
-- Easy to use.
-- Popular and highly available.
-- Ability to draw significant current directly from 12V cheap, popular
- and powerful lead-acid battery (optionally off-grid). Useful for
- powerful electric motors, heaters, soldering irons, radio
- transmitters, etc.
-- Ability to draw limited but stabilized 5V power. Good for digital
- circuits.
-- Ability to have limited and simple 1-wire digital communication.
-
-USB Type A connectors are best match that I found.
-
-The main problem is, I like USB connectors but I want to use different
-and incompatible electrical layout with them.
-
-*Connecting proper USB power supplies, devices and even cables to the
-ones that use alternative electrical layout would do damage!!!*
-
-To avoid accidental mismatches, I mark all connectors/cables and devices that
-use alternative wiring with [[file:stickers.png][printed, laminated warning stickers]].
-
-Alternative wiring schematic:
-#+attr_html: :class responsive-img
-[[file:schematic.png]]
-
-- Outer shell is ground.
-- 2 central pins are re-purposed to deliver +12V and high power.
-- 1 pin is for limited power +5V.
-- 1 pin for 1-Wire data.
-
-Example warning marking on device to indicate that alternative USB
-layout is used here:

-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.
-
-#+attr_html: :class responsive-img
-[[file: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.

- use ordinary ammeter that can handle battery generated current.

-
-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:
-
-#+attr_html: :class responsive-img
-[[file: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.
-
-#+attr_html: :class responsive-img
-[[file: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.
-
-#+attr_html: :class responsive-img
-[[file:make,%20back.png]]
-
-Entire construction is made of parts, no larger than
-120x120x120mm. Maximum for my printer.

-* 20V up-step module
-:PROPERTIES:
-:CUSTOM_ID: portable-stereo-active-speaker-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.
-
-#+attr_html: :class responsive-img
-[[file:20V%20upstep%20module/schematic.png]]
-
-It uses ready made upstep module, but adds extra voltage filtering via
-inductor and capacitors.

-* Mono audio amplifier module
-:PROPERTIES:
-:CUSTOM_ID: portable-stereo-active-speaker-mono-audio-amplifier-module
-:END:
-
-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.
-
-#+attr_html: :class responsive-img

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

-* Front panel
-:PROPERTIES:
-:CUSTOM_ID: portable-stereo-active-speaker-front-panel
-:END:
-
-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.

-* Extra capacitors
-:PROPERTIES:
-:CUSTOM_ID: portable-stereo-active-speaker-extra-capacitors
-:END:
-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.

-Photo of initial PSU + audio amp test:
-#+attr_html: :class responsive-img
-[[file:initial%20test.png]]
-
-Improvement ideas:
-
-+ 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.
-
-+ Add possibility to power device from USB socket in addition to
- batteries.
-
-+ Front panel:
- + Use digital voltage indicator to gauge remaining battery power.
-
- + Add possibility to have multiple inputs.
-
- + It would be better if screw heads were slightly buried within
- construction body.
-
- + Screw holes are too close to the edges on the front panel.

+
+Problem with powerful binoculars is that they are almost unusable
+without tripod. High zoom factor also amplifies hand shakes.
+
+Tripod is not convenient to carry around. Here is an attempt to design
+portable gyro stabilizer that has camera tripod interface. Therefore
+cameras and binoculars can be mounted.

+Old computer hard disk platters are used as rotating discs. They are
+attached to following disk mount:

+* Conclusion
+:PROPERTIES:
+:CUSTOM_ID: gyro-for-binoculars-conclusion
+:END:
+Around half of the stabilizing effect already comes from extra weight
+that is added to binoculars by device itself. Rotating platters
+contribute also about as much. I had only 2 platters. I'm
+contemplating finding more weight to rotate, or even try with old
+CD/DVD disks.
+
+Unfortunately symmetry is not perfect and small high frequency
+vibration is added because of that.

-Problem with powerful binoculars is that they are almost unusable
-without tripod. High zoom factor also amplifies hand shakes.
-
-Tripod is not convenient to carry around. Here is an attempt to design
-portable gyro stabilizer that has camera tripod interface. Therefore
-cameras and binoculars can be mounted.

-Old computer hard disk platters are used as rotating discs. They are
-attached to following disk mount:

-Discs are rotated by electric motor. Motor is cooled by electric fan.

-* Conclusion
-:PROPERTIES:
-:CUSTOM_ID: gyro-for-binoculars-conclusion
-:END:
-Around half of the stabilizing effect already comes from extra weight
-that is added to binoculars by device itself. Rotating platters
-contribute also about as much. I had only 2 platters. I'm
-contemplating finding more weight to rotate, or even try with old
-CD/DVD disks.
-
-Unfortunately symmetry is not perfect and small high frequency
-vibration is added because of that.
