Home Made PCB

admin — Mon, 21 Sep 2009 00:16:01 +0000

There are many ways to create PCB at home. You can manually laying out the traces with trace transfers (not recommended), photo reproduction (specialized, and expensive), or the use of a laser printer using the toner transfer method. During my experience, creating PCB using the toner transfer method is easiest and low cost. The procedure [...]

Arduino Controlling Images on 4D OLEDS

admin — Thu, 17 Sep 2009 21:32:54 +0000

This tutorial inspired by serial OLEDS from 4D Systems. Jenny has pulls it together to make you easy learning how to Controlling Images on 4D OLEDS using Arduino. This project uses µOLED-128-GMD. Before you do any coding you can test run to see if the images are on the card properly by loading images [...]

Constant Current White Led Lamp Driver

admin — Sun, 19 Apr 2009 03:38:58 +0000

We know that most flashlights require three cells because they are regulating output current with only series resister. The odd number of cells except one is not good, and a margin between VLED and VBAT is too small, intensity of light is affected by variation of input voltage within the battery life. The project is a [...]
