ChipHeadBang – design for an USB to Serial converter with ICSP header for (slow) bitbang programming

Monday, April 20th, 2015

microtherion has published new project the ChipHeadBang, that is available on Github: Design for an USB to Serial converter with ICSP header for (slow) bitbang programming, based on the CH340G chip. While this seems to work pretty well, and the CH340G can be obtained extremely cheaply from sources such as AliExpress, driver...

DIY automatic water timer

Wednesday, August 6th, 2014

Kyle wrote an article detailing his DIY automatic water timer: Now that I have power and output figured out, I need to work on the control aspect. 555 timers are great for simple applications requiring up to a few minutes of delay. At 10 minutes, the RC values needed would boarder the danger zone...

ATtiny LED driver for an RC car update

Tuesday, March 4th, 2014

joeforker posted an update on his ATtiny LED driver for an RC car we covered previously: This board delivers 100mA through 2 series-wired LEDs like a champ, powered by a 2S LiPo. Night drives are looking bright. The glaringly bright uncomfortable-coming-straight-towards-you high beam look has been achieved. :-) As usual, mistakes were...

µBoot 2.1 KB USB bootloader for the ATtiny85

Wednesday, September 26th, 2012

Bluebie is developing µBoot, a tiny USB bootloader that only consumes 2.1 Kilobytes of flash on an ATtiny85. It's based on USBaspLoader-tiny85 bootloader but loses ~0.7KB by customizing it's functionality. µBoot is a tiny bootloader for attiny85 chips. Weighing in at just under 2.1kb it leaves more free space to...
