Description: As the field of embedded electronics gets more advanced, hobbyists and professionals are both in need of smaller and more powerful computers. We’ve been looking for awhile and now we’ve found one that we really like, not only because it’s small and fast but because it’s also Arduino shield compatible! The pcDuino is a […]

The Fusion Draw While you might think of glass in its manufactured form, the truth is it’s a material we find in nature. Certain rocks and minerals become glass after coming into contact with high temperatures. This occurs naturally along lava flows and places where lightning has hit the ground. Humans have been creating glass […]

The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in the world accurate time and date. NTP is a simple UDP based protocol and can be implemented in a Microcontroller. Using the tuxgraphics ethernet board and a LCD display we build a nice clock which gets time and date via […]

Google Voice Functions and Features Google Voice’s defining feature is the ability to use one phone number in place of all your existing ones. However, your Google Voice number doesn’t replace your other phone numbers. Think of it as an operator who routes your calls to all your phones for you. It works like this: […]

Programmable DC, AC, current and high-voltage power supplies, electronic loads, UPS, inverters and chargers of low and high power – it is Elektro Automatik. Common laboratory and testing power supplies can be found in an offer of many producers. However, when we need power supplies (including AC), electronic loads, UPS and other components for power […]

Earlier this year I have bought on the flea market a used car GPS system, an Amstrad gp1000. (Un)fortunately it was so badly damaged, that it could not be  repaired, so I thought I would reuse some parts from it. Then came the idea of building a portable GPS logger system. The receiver runs perfectly […]

Project overview This small PCB, which I named Multiuse tiny1 was originally designed to convert NES/SNES controllers to USB. Since there is not a lot of space availabe inside an SNES controller, I designed the PCB to be as small as necessary. The PCB has improved since the beginning, thanks to the many other uses […]

Comparing High-definition Digital Video Cameras Like standard digital video cameras, high-definition digital video cameras (or camcorders) come in many sizes, price ranges and capabilities. One of the bigger differences you’ll want to pay attention to is the camera’s storage method. HD digital video cameras have four main storage formats: MiniDV tape is similar to other […]

So this is a bit of a continuation on my 555 timer based PWM controllers, but now using microcontrollers and MOSFETs instead of 555 ICs and transistors. I made 2 versions, one with switches for speeding up and down and the other with a potentiometer like the previous controllers. I used ATtiny25 controllers running at […]

Massage Chairs: The Mechanical Massage Most massage chairs rely on a combination of motors, gears, rollers and vibrating mechanisms. This kind of chair dates back more than half a century. Over the last few decades they’ve become much more sophisticated. The simplest massage chairs use a series of vibrating surfaces to provide a massage. To […]
