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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
This video discusses electrical overstress of analog integrated circuits.
Make Magazine has a tutorial on the OpenERP enterprise resource planing tool. It’s a project manager for tracking a project from an idea to fulfillment. The tutorial runs through one project example and explains how to setup all the steps … Read more
Here’s an interesting method for designing PCBs that you’d like to mount on heatsinks. This tutorial explains how to make your PCB using thermal tape as the copper substrate. A thin piece of copper is mounted onto thermal tape, then … Read more
Bob picked up a huge LED matrix sign on eBay that has power supply problems. After fixing the power supply, he decided to replace the controler boards with an Arduino. Via Hacked Gadgets.
Thanks to amazing Linux server admin Alex, this site is extremely well backed up. Every hour we make a complete copy of the local harddrive, and then incrementally sync any new data to an offsite storage location. If all this … Read more
