Colour fix extension for MD2 Mainboard

Switchless mod for MegaDrive / Genesis

Switchless region mod for MegaDrive/Genesis

Network card for MiniMega2560 Arduino board. Card supports Arduino Ethernet2.

Info at https://github.com/Sd4Projects/MiniMega2560_NetCard

Note: You will need the 3.3 volt version of the MiniMega2560 board to use the network card.

Bifilar Pancake coil for experimentation. Each winding has 40 turns of a linearly-increasing radius (Archimedean Spiral). Inner-Spiral Spacing is 12.5mils (25mils center-to-center of alternating winding and 50mils center-to-center of same winding) and the Spiral Trace Width is 12.5mils. The calculated inductance of each winding is 62.857uH and the calculated combined inductance in series is 251.428uH (due to the mutual inductance effect).

Trippy RGB, Barrel of Makers version. SPI I&O Expander board. (Brd 2of4)

This is the PCB for a 7 segment LED clock. Find more details at: https://www.thingiverse.com/thing:2947883 and https://git.io/7s

Please use my second version

A simple USB power supply for the ESP8266-01 board. The ESP cannot be soldered directly onto the board (the drill holes are to small :/). You must use a precision socket!!!

Please have a look at at GitHub for updates!

GPIO0, RST and CH_PD are pulled up. GPIO2 is directly connected to J3(1).

J1 : JAE DX4R005J91 µUSB connector

C1 : 100nF

C2 : 10µF

C3 : 100nF

C4 : 22µF

R1 : 10k (CH_PD)

R2 : 10k (RST)

R3 : 10k (GPIO0)

U1 : LT1117IST-3.3

J2 : Used for external sensors

J3 : Used for external sensors

NTC VGA DIP board for C.H.I.P

A small GPIB interfacing circuit that has the connector and the bus drivers. The rest is up to some sort of microprocessor board, for example one of those cheap STM32Fxx boards available.

A simple circuit designed to allow a portablized console to have its USB drive housed inside the unit while still accessible via a micro-USB port to easily transfer new software and games without having to open the unit up. Safely switches the voltage and data lines depending on what’s plugged in and turned on.
