This is the Main PCB for the BikeLapse Camera Trigger. The companion hardware to BikeLapse.com, and open source hardware/software platform for making a virtual catalog of your bike rides or other adventure activities!

With 9V to -9V polarity inverter separated out on same board so that it can be included if needed. All parts listed on board (BOM). Transitor pinout is “standard” 2N3906, so depending on your Germanium transistors, twisting leg may be needed (but in most cases this will work, or you may need to “reverse” them). Transistor pads should allow for easy socketing using standard 2.54mm SIP socket.

power distribution (+5V/-5V) on a molex mini-fit jr 3pos connector. 3 labeled solder connections can take 16 AWG wire. Capacitors and red/green LEDs are optional.

Accurate temperature measurement wemos d1 shield.

• Uses 4 high precision sensors from different manufacturers (STS3x, MCP9804, Si7051, MAX31889)
• Sensors arranged within 11x11 mm square, to share common heat sink (heat source).
• Wemos pins D1,D2 for SCL,SDA i2c.
• Pads available for sensor output, and wemos gpio (solder jumpers as needed)
• OLED 128x64 support with swapable Vcc/Gnd pins to handle different pin styles.

UPDATE:

This board has error with R2 and D3 pin which doesn’t fully go off on Wemos. Instead, I added a jumper wire to another pin (D4 I think).

Otherwise, just leave R2 disconnected and dont use that LED pin. Other data functions and OLED screen work well.

Adapter board for connecting an original Wii bluetooth module (WML-C43 or J27H002) to a PC USB port, for use with Dolphin emulator. Design has been built and tested.

BOM is available on Digikey at: https://www.digikey.com/short/znc74h

The optional switch SW1 is for performing a controller sync; a keyboard key can instead be configured in Dolphin for sync functionality.

See https://wiki.dolphin-emu.org/index.php?title=Bluetooth_Passthrough for instructions on properly configuring your system for Bluetooth passthrough in Dolphin.

allows a raspberry pi to act as a jtag programmer (using openocd). 3.3V targets only!
