AccuTemp

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!

This adapter couples the non-standard Shugart-like floppy interface on an Osborne 1 to a floppy emulator like the GoTek.

The GoTek can be configured as Drive A or B via a jumper on the adapter.

GoTek part number is SFR1M44-U100K Jumper only S1 on the GoTek.

Connector on the GoTek side is Sullins PPPC172LJBN-RC

+5v for the GoTek is taken from the floppy cable.

A basic Atmel AT328P controller with two 4-bit data ports exposed for hookup to external circuits - specifically the ubiquitous L298N stepper motor driver.

The I2CIO is equipped for connection to the Sparkfun QWIIC I2C bus ecosystem.

connects 4 terminals of a source-measure unit (SMU) to a triax connector (for force_high) and a coax connector (for force_low). Correctly surrounds force_high with copper connected to guard terminal.
