We are proud to announce the “Get Paid to Publish your Project” program here at Electronics-Lab.com. Every project published under project section will get an instant PayPal payment of 80$ USD.

Get ready to submit your project at Electronics-Lab. To participate send your project to webmaster @ electronics-lab.com with “Get Paid to Publish your Project” in subject line and your project as attachment. Common file types (.doc, .jpg, .pdf etc) are accepted. After reviewing your project and approved for publication it will be published under project section and you receive the payment to your PayPal account. So simple!

A project to be valid should be:

  •  A high quality project.
  • Designed by you.
  • Not published elsewhere on the web.
  • Has clear schematics, photos, description and PCB.

Every project approved will be published and will receive the payment. You will notified by email if your project is accepted.

If you have any questions, don’t hesitate to contact us

This video shows a LED powered by a 0.1 Farad capacitor. First the capacitor is charged at 5V and then it is discharged through the led. The led is light for a few minutes after power is disconnected.

This project shows how to use an Arduino to read the signal from a set of digital calipers and send the reading over USB. In other words it adds USB functionality to digital calipers. A great reference on reading digital callipers can be found here . This project explores the details of another protocol found to be in use on some callipers. Check project details on the link below.

This project shows how to build a LED matchstick that is light up if strike it against a normal matchbox filled with neodymium magnets.

The LED matchstick has an inductive sensor that detects the magnetic field as you strike the matchstick against the matchbox and it lights up a LED in a flickering fashion. The power to the matchstick is through a 3F/2.7V supercapacitor and a DC-DC converter. As the LED lights up, the supercapacitor discharges and eventually the matchstick splutters off just like a normal matchstick.

This project shows how to build a LED circuit that is pulse fading – breathing like the “Macintosh” style LED fade off effect. The circuit is using plain electronic components like transistors, resistors and capacitors. To make LED fade on and off you just have to push a push button or trigger the input using square wave from a 555 timer IC. The producing effect is really nice. Find schematic and project details on the link below. [via]
