Power OR circuit using Schottky Diodes made in Altium Circuit Maker with 4 Layers. Testing both OSHPark 4 layer boards and Learning Circuit Maker.

This is a board I made after reading an article on RobotRoom.com by David Cook regarding Solar Charging. link - https://robotroom.com/Solar-Recharging-3.html

To disable charging, do not populate D3. All information in his article applies.

2 Layer functional test board using Altium CircuitMaker with a “Power OR” circuit that has charging capabilities through D3 from P1 which will only charge P2 if D3 is populated. All Voltage signals are pulled out through P3 which can be made breadboard friendly by using a right angle pin header. UNTESTED PCB - USE AT YOUR OWN RISK! Shottky Diodes are D1, D2, D3 to suit the power needs.

A breakout board for a mini linear stepper motor with a 4 pad connector on 0.8mm centers. The board has holes for mounting the frame using solder.

All sizing is guessed, this is my 4th version, V3.1, after size testing the previous 3. The motors are available on Amazon in qty’s of 50 there is no documentation on these, but I’ve been toying with the measurements and custom PCB’s for months… I will update this description with photos of the actual boards populated with the motors.

The plastic nut on the shaft of these motors take very small stiff wire lodged in the opening and it will have about 4mm of motion. The wire should be about 0.2mm to 0.4mm, very thin! Soldering by hand needs to be done very quick or the flex material will melt, even with a 110V - 15W iron. Very little room for error when soldering.

This board is hopefully the final test, but it may need further revision.

Single button keypad. Works as Active High or Low by reversing the power input pins as stated on back of board. No mounting holes. Glue/Epoxy in place.

Takes a through hole 6mm push-button tactile switch and a 603 resistor. Will update with real photos when parts are received and tested :)

A Spinny Thingy. This has some custom pads that I will be testing. V1.0 is a sizing test.
