A bench power supply is a must for any hardware tinkerer, this DIY Digital Bench Power Supply by Microsyl is a bit high end and much more than you need but in the end you will have a great system to enhance your bench. If you would like to make one from parts you probably have laying around you can make a cheap bench power supply from a spare ATX
The guys over at Nerd Kits have made a cool Human Theremin project that uses Infrared Light. IR light from an infrared LED is bounced off someones hand and some of the light is reflected back onto an infrared transistor. The closer the hands are the more IR light is reflected back onto the IR transistor. The output of the IR circuit is fed into a Nerd Kit microcontroller and
We have seen some amazing Quadrocopters in the past but this Wooden Quadrocopter adds the emphasis on the Quadcopter body and structure. There are no less than four types of wood that have been machined into this incredible machine. The parts were designed based on an older kit and redesigned to be made from wood, the alien detail in the top dome is very well done. If you want to
When you are on vacation your animals still need water. That’s the premise of this Automatic Pet Water Bowl Filler project by ihmech. It monitors the level of the water in the pet water bowl and opens the water valve to fill it whenever it detects that it’s low. There are lots of safety features to prevent the system from flooding the basement. The simple solution of installing a float
With Halloween right around the corner cutting foam to make things like fake tombstones is something some of us will be thinking about. There are lots of ways to get the job done, you could use the standard utility knife or make a wire cutting CNC machine. But with a bit of time and a few dollars of parts (or possible no cost in parts based on the size of
Are your hands cramping after playing your favorite game on your Game Boy Advance? Have a look at this Game Boy Advance Rapid Fire Hack by the Hackers Workbench to give your fingers a break. This circuit will simulate you tapping the B button for all you’re worth. The other nice thing about the design is since there only a few components you can just dead bug it right inside
Over at Karosium there is a DIY DS1821 based Thermostat project. The code is available and I am assuming if there are some requests that the schematic will also be posted. “After configuration for thermostat mode the center (1Wire DQ) pin becomes a thermostat output pin. Since it’s still an open collector pin it needs a pull up resistor, and since it’s still basically a 4mA GPIO a transistor at
