Well this sound amazing and scary. Everyone knows that printer toner usually is transferred with special glossy paper and iron, but printing directly… anyway fact is that it is possible and gives amazing results. Author claims and proves that he was able to print 2mill traces what means four traces between two DIP pins. There [...]

You have to prepare many multi-platform eagle designs for manufacture, but you have no ideas what to do about it? Well, there are many ways to turn an eagle design into an actual PCB. One of the best ways is to save the eagle designs as industry-standard gerber files, where you can use the gerbers [...]

Probably you have read about our PCB etcher on our site. We planed to make it fully automatic with heater, bubble machine and thermostat. But fact is that it wasn’t finished. But we are actively using it with aquarium heater only and manual mixing :). If you are looking for something similar that has a [...]

This PCB drill is made of wood and looks really cool. Wouldn’t mind to have one on my table. Design is very unique – it uses various custom made parts, motors from old printers and VCR’s. Author even simulated all design code on a Labcenter’s Proteus VSM.

Still struggling with various PCB making technologies and cannot do it right, you should try Photo Etching method which is becoming more and more common among radio amateurs. All materials needed are easily accessed. Probably the hardest part is to obtain UV light source. But you can find tons of sources on the internet how [...]

The term circuit technology usually refers to the various techniques that used in the manufacture of electrical circuits. A large number of devices that are used today make use of printed circuit boards (PCBs). These devices provide a mechanical support for the various components present within the given device and also, the electrical connections between [...]

I came across this interesting project. The guy decided to make UV PCB exposure box made of UV light LED’s. The main reason why he used LED was the power dissipation and compactness. Assuming that one UV tube would take about 6W while one UV LED would take about (20mAx3.2V=64mW). Most of that energy UV [...]

Lets go through few examples how to place electronic parts correctly on PCB board. SMD electronic parts especially if lead pitch is above 1 mm, then placement of leads has to be symmetrical on copper planes: If IC has smaller lead pitch like 0.5 – 0.8mm positioning by hand become harder. Sometimes it is recommended [...]

How repeatedly make good PCB? Many hobbyists faces this issue every time they are prototyping their ideas. Designing the PCB layout (doesn’t matter is it a through hole or surface mount) may be tricky task especially when dealing with dimensions like 0.2mm tracks or 0.5mm surface mount pitches. Laser printer, plotting or other similar transfer [...]

After UV-80 vas built there was a thought about automatic PCB Etcher with autonomous Heater and bubble machine. This project is hanging in prefinished phase but it does a job. It was used to etch several PCB’s. As this etcher supposed to be used for making PCB’s using photoresitive technology, the controller supposed to control [...]
