| 説明 | I made that homebrew Drawdio today. I used my own home-etched circuit board. I made some changes on the design, 'cause i couldnt find all parts that adafruit used. I used the 555 and a 9V battery. I also used two 9.1Mohm resistors in a row instead of the 20 Mohm. The tiny speaker is from a toy. I'll share pcb layout and schematics on my blog when i have the time to post it.resistor.blogsport.deedit: schematic and PCB-layout now online: resistor.blogsport.de/images/drawdio.zip |
