A cartridge adapter to allow custom reproduction QCards to be [re]programmed after assembly. Requires a 36-pin card edge connector and two rows of header pins. Intended for use with a TL866 programmer.

Flex circuit to test SiPM’s on a long flex cable for ePIC. BE SURE TO ORDER THIS AS A FLEX!!

Allows you to select one of the voltages available from a USB-C power adapter, with a continuous display of the current consumption.

The pbcb Power
- This boards small. how small is it? So small I had to put multiple so it’d be big enough for pcb fabs to make it. - It’s no bigger than the port itself.
- Can be printed small enough the resistors can face the port itself instead of sticking off the back.
- Through hole port for strength, keeping the entire thing small, allow for one sided assembly of the resistors so you don’t have to solder those on yourself, makes it more noob friendly.
- has large copper areas to help prevent pad burn off, making it more noob friendly to put together/use
- Port. For the resistor you can use any 5.1kΩ.
- Use a max board thickness 0.8mm. - Has extra useless stuff removed to make it cheaper on here

Small flex PCB that you can cut up as needed for circuit bodging with 0603 components.

This board mounts on the existing binding posts of a BK Precision 8500 electronic load to add standard banana jacks.

See the original blog post here https://tolisdiy.com/2022/02/17/adding-banana-jack-and-front-remote-sense-terminals-to-electronic-load/

The part numbers for the jacks are CT3151V1-0/CT3151V1-2 for the black/red connectors

North Coast Modular Collective presents: A super simple oscillator

The goal of this project is to create a super simple oscillator that can be used for teaching basic electronics, basic DIY, and basic synthesis with low cost and low risk.

“Mt. Brighton Avalanche Oscillator” is a community developed and open-source kit designed specifically for learning. Its low part count, low complexity, and low cost is coupled with a transparency in design and function that makes it easier to understand and describe what is happening with the electricity and sound. When complete, you’ll have a simple, standalone battery operated synthesizer with a single knob for changing the pitch of the sound that you can plug headphones into, or other music gear.

Open source design of battery powered (M12 Milwaukee) fan speed controller.

This unit, based on an Arduino module, provides the same capabilities as an NCE Auxiliary Input Unit. Fourteen inputs are available to report the position of turnouts or for connection to block occupancy detectors or other devices. The unit can be powered either from the NCE Cab Bus (Like the NCE AIU) or via an external supply, 9-16volts AC or DC.

A PIM breakout board that has the typical PICKIT programming header broken out. Provides a way to power the PIM via a screw terminal.

A simple adapter to connect ARMT Cotext development boards SEGGER’s J-Link and also provide access to the virtual COM port.

The adapter can be directly plugged into the 20-pin JTAG interface. On the other side, the 10-pin header JP2 can be connected to the SWD interface of the dev kit. J-Link requires a connection to the target VDD as well. Finally, the J-Link provides a 5V output, which can be used to power the dev board as well (please check documentation about how to configure this)
