+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.
+</p>
+
+<p>
+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.
+</p>
+
+<p>
+For extra clarity, this one important button:
+</p>
+<ul class="org-ul">
+<li>Is painted red.
+</li>
+<li>Has exaggerated surface and relief raising above main case surface.
+</li>
+<li>Has big white circle around it (I used <a href="https://en.wikipedia.org/wiki/Airbrush">airbrush</a> with stencil to
+paint the circle).

+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.

+
+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 [[https://en.wikipedia.org/wiki/Airbrush][airbrush]] with stencil to
+ paint the circle).
+
+** Original Nokia 105 (2019)
+[[file: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.
+
+** Enlarged dial button

+Simple charger and terminal (front-end) for 12V lead-acid battery.
+</p>
+
+<p>
+Idea is to distribute power from rechargeable 12V battery to various
+appliances (soldering iron, radio transmitters, etc..) while also
+providing use-charging in the background.
+</p>
+
+<p>
+Single on/off button disconnects battery and up-step voltage source
+from front panel terminal connectors.

+is used to feed voltage up-step. Up-step is tuned to ~14.4 V.

+[[file:make.png]]
+
+[[file:make,%202.png]]
+
+Simple charger and terminal (front-end) for 12V lead-acid battery.
+
+Idea is to distribute power from rechargeable 12V battery to various
+appliances (soldering iron, radio transmitters, etc..) while also
+providing use-charging in the background.
+
+Single on/off button disconnects battery and up-step voltage source
+from front panel terminal connectors.
+
+[[https://www.amazon.de/gp/product/B07G4KWV6S/ref=ppx_yo_dt_b_asin_title_o08_s01?ie=UTF8&psc=1][Tecnoiot MT3608]] voltage up-step is used. 3V DC external power supply
+is used to feed voltage up-step. Up-step is tuned to ~14.4 V.
+
+[[file:schematic.png]]
+
+Current design is rather of blog (experience sharing) value. It has
+quite some drawbacks:
+
+- Warning: Circuit has dangerous instability. Requires low voltage
+ ~3V but relatively high current external power supply. Using
+ higher voltage but low current power supply could easily lead to
+ situation where step-up generated load pushes power supply output
+ voltage down too much. This leads to too much power being lost
+ within power supply and easily leads to power supply overheating!
+
+- There is no dedicated current limiter. 3V external power supply
+ and up-step are acting as current limiters.
+
+- While RCA connectors do work as DC power connectors, but are not
+ intended to be used this way and are not very reliable.
+
+- Voltage up-step provided output is not very clean. Extra capacitors
+ and induction coils could be added to remove high frequency noise in
+ the voltage.
+
+- Metallic and shielded body would be helpful to reduce
+ electromagnetic/radio noise generated by step-up.
