Fresh hacks every day
[Steve] created an AVR programmer using an old USB keyboard. We feature a bunch of AVR programmers, but this one is made from parts that many people will have lying around. There are two components: the controller PCB from a USB keyboard, and an optocoupler for emulating key presses. In order to send data to the AVR, [Steve] used the LED outputs on the keyboard. These LEDs can easily be toggled … [Read more...]
[Natsfr] was looking for a single-sided PCB to host a PIC 18F4550. Not finding one he designed his own in Kicad and is sharing (translated) the spoils of his labor. This chip has USB capabilities which is why we see it used in a ton of projects. Almost all of them (including this USB input device post) use a very large DIP package. [Natsfr] went a different route, designing for the TQFP … [Read more...]
We have seen a few very nice and polished AVR based projects from [Manekinen] over the last few years. Now he has just finished his latest project, the µProg, a super tiny complete AVR programmer with a bunch of features. The µProg completely eliminates the need for a computer to program your embedded AVR chips. The programmer fits entirely behind an LPH7779 graphics display, and accepts any … [Read more...]
