3dpBurner is an open source laser cutter/engraver. It is created with the same concept as RepRap, using 3D printed parts and some easy to find “vitamins” (non printed hardware). I tried to make it as cheap as possible, by using cheap electronics and a “low power” laser (a laser diode). The X/Y working area is […]

Being new to Arduino I was a bit overwhelmed by the different ways to do things. So this is what I came up with! I am using an Arduino UNO R3 clone but the connections I believe are the same for most Arduino’s or can be easily modified for your particular model. This project is

The WiFi SSR board project changed a bit and I use classical relays instead of SSRs now. The reason is that SSRs tend to get quite hot when switching larger loads, and the 8A relays I last used actually could be used for max 2.5A load switching with no heat sink. The high quality relays I

AC/DC modules Traco TMPS 03 with dimensions of 1“x1“x0,6“ represent a top-class solution of power supply with minimum space requirement. Power supplies with a high power density (W/cm3) are nowadays offered by several producers. However, perhaps the biggest challenge is a miniature power supply with a power of say a few Watts. It´s because even
One „inch“ will provide you 3 Watts Continue Reading
Frequency counter using Arduino (upto 40KHz). Many guys here were asking for a frequency counter and at last I got enough time to make one. This frequency counter using arduino is based on the UNO version and can count up to 40KHz. A 16×2 LCD display is used for displaying the frequency count. The circuit
