Quuit PCB Round 1

Breakout Board for Alps Alpine RKJXT1F42001 Rotary Joystick, with DNL’d PUs/PDs.

I ordered my stock of these units from RS Electronics EU as there were no US distributors with stock at the time. Looks like Mouser has since received stock after I ordered: RKJXT1F42001 @ Mouser

One note on the symbol/footprint available from Mouser, Pin 11 (footprint ref desig D_2, iirc) is for the positioning lug that is molded into the housing on the RJS and has no electrical connection. The datasheet footprint suggests a 1.1mm diameter hole is needed. The footprint I downloaded from Mouser, iirc, provides for a 1.0mm hole. I manually edited the footprint to make it a 1.1mm hole. Will update this if it proves to be not needed, or if other needed changes are discovered after the board gets stuffed.

Breakout board for the TDK InvenSense ICP-10100 barometric pressure sensor. These sensors have a very high resolution, measuring pressure changes of as little as 1 Pascal, which is equivalent to a 8.5cm change in elevation.

Arduino library and KiCad design files available on Github

This is the board for ZULF’s soldering tutorial. Learn how to solder through-hole and surface mount resistors, and light up some LEDs. If you order this board using OSHpark’s “after dark” service, you’ll get to see the printed circuit traces more clearly as they will not be covered up by an opaque solder mask layer.

Bill of materials: - After dark board - 3 x 1 kohm, through-hole resistors. Solder to front of board. - 4 x 1 kohm, 1206 surface-mount resistors. Solder to front of board. - 5 x 1 kohm, 0805 surface-mount resistors. Solder to front of board. - 5 x 1 kohm, 0603 surface-mount resistors. Solder to front of board. - 4 x 0603 surface-mount LEDs. Solder to front of board. - 2 x AA battery holder with connector wires. Solder to reverse of board. - 2 x AA batteries

Second revision of the RadPC Toupee. Takes in +28VDC and brings it down to +5VDC using a high range switching regulator. Additionally, it includes an RS422 to UART transceiver for comms to our proprietary RadPC Lunar single board computer.

Fixes issues in the original TCIB board design by Soulkilla

A circuit for interlocking a Koheron laser driver with either a 12V active shutter line or normally closed room interlock circuit. When the room interlock 12V line goes low or the normally closed circuit opens, the LCK pin on the Koheron driver board is pulled low via the optocoupler. This board utilises the same 12V PSU as the Koheron driver.
