 based on my newest KeyWrite, i made a LedTester. when building a pinball machine or jukebox, i always have the need to take a teensy and solder a connector to it to test the led with a testprogram. this thing is now a dedicated ledtester which is ready for all the led projects.

 

 When i am making my custom microcontroller, the chip has to be flashed one time with ICSP. With this tool i can do that without soldering on cables. After that i can program the microcontroller with arduino ide with usb. https://www.thingiverse.com/thing:6831010
