DIY Breakout Board FT232RL from sparkfun
One day ordering parts for ongoing projects I ordered a chip FT232RL planning to make USB to UART adapter.
STM32DIP40 mini development board
A year ago bought a Discovery VL it is very interesting thing and does not cost so much.
But it is not very convenient to use it in “Breadboard” as it has a number of medium contacts that prevent paste it into Breadboard.
So people sometimes doingl so.
DIY PCB with flat VIA’s
Catching up the development of printed circuit boards at home i often faced with the problem of “the bulbous” vias. Usually homemade double-layer boards soldering from both sides with the thin wire, the result usually satisfied but if you need to make VIA under the chip TQFP48, SOIC16 and that’s is a real problem, if contact is very bulbous it will be simply impossible cleanly solder chip as its legs will hang in the air.
I suggest you create your own version of flat vias.
Nebulophone microcontroller synthesizer project sounds great
Judging from the video (found after the break) the Nebulophone is one of the best sounding DIY synthesizers we’ve seen. Especially when you consider the simplicity of the hardware design. It uses an AVR chip and an OpAmp. The rest of the parts are just a few handfuls of inexpensive components.
