ATTiny based Electronic Candle Our friend Pete Mills developed this great ATTiny based Electronic Candle, we have seen electronic candles before but what makes this one shine is how the flickering was done. Pete actually sampled the actual flicker patterns of a real candle flame so that this reproduced flame would look as close to the real thing as possible. You can see some other electronic candle designs here for inspiration. “The ATTiny Candle is an LED candle. I figured the hardest part of this project would be making the flicker look realistic, so I decided to let nature do that part for me.
EngBlaze | Arduino, AVR, and hardware hacks, oh my. Electronics DIY - Electronic Schematics FM Transmitters TV Transmitters Stereo Transmitters 555 Timer Business Cards | Cody Shaw Hello! So I thought up this cool little project during my last few weeks during my co-op term at Echologics Engineering. I saw everyone had nice, professional looking business cards, and I needed something to springboard myself into PCB design and manufacture. One and one came together, and this idea came about. There were quite a few idea revisions in my mind before I actually got around to spinning the PCB. First idea: a photoresistor of course! Current in parallel with a normal resistor, of course! Then came the digitization! The idea behind the circuit is that you lay a 9 volt battery on the terminals, and the circuit then operates as expected (see video). The card features my personal info, as well as one of my favourite Tesla quotes on the backside. And there it is! Here’s the card in action! Best, Cody Like this: Like Loading...

Main - open-plc - OpenPLC - an open hardware alternative for automation OpenPLC is an open hardware alternative for industrial and home automation. It uses the well known ATmega chips as main processor, the same used on Arduino. This means that OpenPLC is code-compatible with all arduino sketches. The main features of the OpenPLC are: ● Protected 24V Digital Inputs (8 inputs for each module) ● Protected 24V Digital Outputs (8 inputs for each module) ● USB Communication (used for programming) ● RS-485 bus for communication between modules ● Open Source IDE with c++ programming ● Open Source IDE with Ladder programming ● Integrated Ethernet ● 16MHz ATmega2560 as main processor November 29, 2013 Finally the boards are done! We made a benchmark with a Siemens S7-200 PLC. September 9, 2013 I'm very happy to announce here that the OpenPLC Ladder is finally ready for it's first public beta! If you want to download the binary files, just click HERE. NOTE: You can upload the openplc ladder code to a standard Arduino Mega as it has the same processor of the OpenPLC May 25, 2013
