An FPC to 0.1" header breakout board for a Fujitsu thermal print head

Adapter for the Supermicro’s X9SCM Front Control Panel connector

A controled MOSFET switch based on MVMFS5834

Reattempt

C64 Powerbox IEC Switcher. A little board to switch 4 IEC drives between two busses for sharing on C64/C128

Second version of the solenoid controller board for the Mouse Piano platform. Fixes a missing trace from V1, and reoriented connectors.

Tested & works great. Hand soldering is quite manageable, with the 0.65mm pitch IC pins of the FT232RL being the biggest challenge present.
A derivative of my v3 IC-only module. Same size/cost as v3.
The difference? This board is self-contained, and adds pads for a resettable fuse next to the USB header pads. (No, not specifically pads for a type-A USB male plug - you supply a cable and plug like this as I have done and attached via short pieces of 20-gauge wire, with good results. Uses standard USB order of +5v, Data(–), Data(+), GND / AKA the standard color coded red, white, green, black.)

Known issues:
* The data direction arrows point the wrong way relative to actual data flow… or you could say the TX and RX LEDs are in the wrong order due in part to a vague datasheet, but fixing the silkscreen arrows might be the easier fix.
* 6-pin FTDI-type header was designed for a female pin header and consequently has its drill size just a bit too small for standard square (male) pin headers - tested grinding down the pin corners to an octagonal shape, and it does indeed fit in there okay that way.
* Because of its double-sided nature - rather than riding on a single-sided carrier - it’s not very well suited for the slide-in bay on my Modul-Ar-duino. Perhaps double-sided foam tape plus a layer of rigid plastic over it may compensate for that.

LTC6431 dev board

Minimal breakout board for the STM32F030F4P6

BOM:

• 1 x STM32F030F4P6
• 2 x 0603 capacitor 100 nF
• 1 x 0603 capacitor 10 nF
• 1 x 0603 LED
• 1 x 0603 resistor 330 ohm
• 1 x push button with that funky footprint

Fixed the errors from the first version, this is now tested, it works as it should. But i’m just redoing the whole schematics and PCB Layout. You can find everything about this project on my Git and on Hennes Git(he does the Software work on our Projects)

Version 0.2, fixed RFM7x

Direct connect RFM12x/6x/9x/7x Module to all Raspberrys.

Please use the jumper to choose CE0(GPIO08) or CE1(GPIO07) select pin for youre Module.

Here some notes to every Module:

RFM12x: Connect a RFM12 or RFM12b Module direct to RPI. Special Pin: IRQ => GPIO25

RFM6x: Connect a RFM65 or RFM69(W/HW) direct to RPI. Special pin: IRQ => GPIO25

RFM9x: Connect RFM95, RFM96, RFM98 and RFM92 LoRa Modules direct to Raspberry. Special Pin: DIO0 => GPIO25 and DIO5 => GPIO24

RF7x: Connect RFM70, RFM73 RFM75 to Raspberry. IRQ => GPIO25 and CE => GPIO24

This are a Prototype and not testet. Please care!

Light Strip Rev 01

Use these boards to recycle the MPU6050 gyro off your old / broken flight controllers. I pull them off broken toy grade all-in-one integrated controllers mostly. In the end you only save a few bucks but I hate seeing good parts go in the bin cause I dont have use for the board as a whole.

Note this is a 3v3 board only, DO NOT apply 5V or you WILL kill the gyro, it’s a 3.6v max iC and the common GY-521 breakout has an on board regulator, again this one DOES NOT and only takes 3.3V in! This is prrety much the sparkfun board but with the addition of a indicator LED.

Wireless Home Control System (WHCS) main board (base station) for the University of Central Florida’s Senior Design. This board acts as the main controller for a home filled with control modules. It displays their status on the mounted LCD and communicates with an Android device over BlueTooth for remote control.

Interfaces with Adafruit’s 2.8" TFT LCD, HC-05 BlueTooth module, and an NRF24L01+.

Full project documentation available here (warning: PDF).
