Creating Android BLE app
Dany over at Elecfreaks writes: If you are an electronics enthusiast, and also fond of programming, I would be very glad to share with you an Android BLE application development method, so you can integrate the phone and MCU to do some more interesting things. Right now we begin to explain how to develop an […]
DIY 30 watt stereo amplifier circuit
An article on a DIY 30 watt stereo amplifier circuit by Ron Hoffman over at Gadgetronicx: The Stereo Amplifiers are quite handy in places where we need to amplify the input signals to make it audible for all. Weather it was a party or a simple meeting, this thing will do a perfect job in there. This […]
EWaste 60$ 3D printer
A DIY 3D Printer built out of reused electronic parts by mikelllc, an instructables here: This project describes the design of a very low budget 3D Printer that is mainly built out of recycled electronic components. The result is a small format printer for less than 100$. First of all, we learn how a generic CNC system works (by […]
Tutorial : Control your launchpad using your voice
Antscran over at the 430h forum posted a how-to on using an Android phone and voice commands to control a MSP430G2553: In this tutorial I will demonstrate a MSP430 voice control over Bluetooth, using a HC06 Bluetooth module. I will be using an Android App I programmed which can be downloaded and installed, the C […]
Dirty DIY stencils
Matt Mets of Blinkinlabs shared a tutorial on making solder paste stencils quickly by hand: This is a truly quick and dirty method for making solder masks, and is nice because it only requires a few hand tools. It’s great for situations when you want to test a new design or make a single, small […]
Burn c into other chips using Arduino Duemilanove
Kathy Yang writes, “We may often encounter such situation as bootloader falls off when using Arduino, this thing can freak us out especially when we got no bootloader tools on hand. So what shall we do? Here we’ll introduce a way on how to burn c via Arduino, which is rather practical in cases when without […]

Rupert Hirst of RunAwayBrainz writes: Surface mount component removal can often be tricky. With a little thought, and a piece of copper wire, small components can now be safely and cleanly removed, without damage to either the component or PCB tracks. In the following video I show you how to make an quick and simple […]
Kicad Tutorial: Using the autorouter
WayneAndLayne is doing a series of short Kicad tutorials. This next tutorial in the series will show you how to use autorouter: Routing, the process of connecting all the pads of a printed circuit board (PCB) layout, can be a time-consuming and tedious process. To avoid the time and frustration of manually routing your PCB, there […]
App note: Resistive bridge basics – Part One
Part One – Resistive bridge basics: Bridge circuits are a time-honored way to make accurate measurement of resistance and other analog values. This article covers the basics of bridge circuits and shows how to use them to make accurate measurements in practical environments. It details the key concerns of bridge-circuit applications such as noise, offset […]
Kicad tutorial: PCB edges
Here’s a short Kicad tutorial by Wayne and Layne: PCB edges An important part of designing a PCB is to clearly indicate the outline of the board, so the board house will know how to cut your boards apart. Most PCBs are rectangular, but sometimes you want to add a more complex outline (like a […]
