A BNC input board for the IF-C01COMG Clone also present here.

This is rev. B with proper stereo-to-mono circuit.

I have NOT tried it out myself yet…

RGB SCART daughter board for the IF-C01COMG Clone board. This board also has support for a sync stripper circuit selectable by SW2. If enabled the LED in D1 will light up. Supported sync strippers are LM1881 and EL1883 (and whatever other pin compatible). LM1881 supports running directly off 12V and thus if using this, close the JP1 jumper with solder, and you can then skip U2 and its two capacitors C5 and C6. EL1883 runs off 5V, which must then be supplied by U2, and JP2 then needs to be closed instead. THEREFORE ONLY CLOSE EITHER JP1 OR JP2, NOT BOTH!

This is Rev. B with the stereo-to-mono fixed properly.

SW1 selects to route audio to stereo RCA plugs or to internal mono audio.

SW1 and SW2 can also be omitted and jumped accordingly (the switches are quite expensive…)

Connect the two boards with a Molex 15267-0300 FPC cable (Mouser P/N: 538-15267-0300)

The mechanical slots for the SCART plug are hacked in due to OSHParks missing oval slot support. It should be good though.

Simple adapter for 10 pin 1.27 mm to 2.54 mm headers. pins are mapped 1 to 1. P1 connects to Atmel-ICE. P2 connects to system under test.

Atmel ICE ISP (SPI) adapter. Transitions from 10 pin 1.27mm header to Atmel ISP 2.54 mm connector

This One Tube Nixie Clock adapter is for any side-view tube that uses a B13B socket. This includes ZM1040, ZM1042, Z566, Z5660M, Z522M and Z5220M. These tubes have 1mm pins that plug in to a socket. This board is intended to use mill-max sockets 8331-0-15-16-27-10-0 which are available on digikey

The board includes pads for a neopixel and for a current limiting resistor

For use with USB to VGA adapters and Osmo-fl2k.

The RED “transmit” pin from the adapter is broken out to an SMA connector. The +5V pin is used to drive an optional power LED. The Cable Detect pins are broken out to solder jumpers to connect them to ground. Cable detect is taken care of in software so these are not currently needed, but I broke them out just in case.

This board does not provide impedance matching, attenuation or filtering. It is merely an SMA breakout.

Bill of Materials:

• VGA Connector: DSUB HD15 Right Angle (Digikey PN# A31927-ND)
• SMA Connector: Edge launch SMA for .062" PCB (Digikey PN# CON-SMA-EDGE-S-ND)
• Power LED: 0805 (optional)
• R1: 0805 470Ω to 1kΩ (optional)

This devices adds a midi input and outputs for Clock and Random for MI Grids. It also features a 1x4midi through. The TRS to midi cables are wired according to the “Type-B” scheme, meaning Tip-> Pin 4, Sleev-> Pin 5 on the midi connector.
