I was shocked when I saw this Volt Meter Style Clock, it is close to a design that is sitting on my bench right now! My design should be done in 2 or 3 weeks. I love the minimal parts count of this project, since it is battery powered there is no power regulation section and that helps keep the circuit nice and simple. If you want to make your
This Temperature Control project interfaces a DS1621 temperature sensor to a ATtiny 2313 micrcontroller, with some AVR Bascom code a relay is controlled based on temperature. This is a very useful project since it has many applications, you could use it to turn on your car block heater when it gets cold, or turn on your attic fan when it gets real hot in the attic. Full code and schematics
This LED Candle project by macobt is nice and simple, plus the effect is enhanced because the LED is actually mounted in a real candle. We have seen other LED Candle projects here in the past but this one has a great finished look to it. If you have a spare PIC12F675 laying around you might want to give it a try, the code and schematic is provided here.
The Harford Hackerspace has been building a CNC machine. You can see all the build details here. This machine is a huge success! The Z axis can lift an amazing 65 lbs and it has no problem cutting metal throwing stars. What more testing do you need? I think we can call the build done at this point. “The CNC machine’s construction has advanced to the point where we can
So going to CES was not in the cards for me this year. Not a problem since I am not all that interested in the mainstream stuff anyway. I am more interested in the far out gadgets and some of the crazy products that may not find it in consumers hands. I have mainly been following the coverage from Zedomax, Hack a Day and Makezine. This phone watch that does
This Step-a-Sketch project is sure to bring back some memories if you are around my age. I remember having one of these growing up, I think I got it for a Christmas present one year. Unfortunately it was killed when I was going through my how does this work phase. Almost everything with screws around me got taken apart, some were even put back successfully. By using a PIC 16f84a
If you have a hard time coming up with a good excuse in a split second then you need this PIC 16F690 based Emergency Excuse Generator. Next time the boss calls all you will need to do is give the big red button a press and bingo you will have an instant excuse to recite to your boss. 🙂 Full build details, code and schematics are provided. I haven’t heard
