The materials are released under the terms below. I don’t have time for pedantic nonsense or legal theory and like to keep things simple. I call this the ‘Mike Chi’ license.

*For each project, at my sole discretion, I may release whatever sources, to whatever level of abstraction, that I deem appropriate. Additional information/materials may be released on a scheduled determined at my sole discretion.

PNP Proximity Sensor breakout board. Connect 24V-36V, 5V, and ground, and this board distributes power to up to three (3) PNP proximity sensors, level shifts the sensor active input signal, conditions them and sends the signals to your CNC breakout board inputs, at TTL logic levels.

Requires 1x74LS04, 3x1N914 diodes, 3x4.7K resistors, 3x1K resistors, 3x220R and 3x5mm LEDS and 3.81mm connectors (optional).

Xbee breakout/adapter board. Converted Eagle files from Adafruit to Kicad. This board seems to be unavailable from Adafruit at this time, superseded by a USB version with FTDI onboard.

[NOTE: This board hasn’t been tested yet. It’s simple enough that I’m fairly certain it’s OK, but in case it’s not, this is why. After I test it, I’ll remove this note.]

This is a breadboard adapter for accommodating two vertical RCA connectors, specifically ones from CUI Devices RCJ-02 series. (I specifically like RCJ-024 since its yellow and I intend to use these for video.) It’s based on a similar board I made for Thonkiconn-style 3.5mm mono jacks. This one uses a ground plane and thicker traces, just in case it matters for my video use cases.

BOM:

• (2) CUI Devices RCJ-024 Yellow RCA Phono Connectors (or a different color from the RCJ-02 series) [Mouser part #: 490-RCJ-024]
• (2) 2x3 0.1"-spacing pin headers
