Fresh hacks every day
After years of prototyping hobby electronics we've learned (several times actually) that when something's not working it's a problem with the hardware. Usually the jumper wires aren't hooked up correctly, or we needed to throw a pull-up resistor in and forgot to. One thing that can really help sort these problems out quickly is a pinout label for each chip like the ones seen above. This is a … [Read more...]
What can you do with a broken Compaq SLT 286? Its briefcase-like size and shape actually make for a pretty interesting portable electronic prototyping station. [Philip] gutted the components and started adding back the items he most commonly uses when developing a project. He shares all of the details in the video after the break. At center stage is a double breadboard where the keyboard would … [Read more...]
[Erv] was putting his holiday shopping list together and decided that instead of buying his friends something from the store, he would give them something a bit more useful. A former Electrical Engineer by trade, [Erv] typically prefers PIC microcontrollers, but he says that Arduinos are just so convenient to use for prototyping that he likes to always have one on hand. He figured that his … [Read more...]
[Rajendra] got tired of building the same basic circuits time and again on the breadboard. He decided to build some simple, modular circuits on protoboard and make them easy to interface with the breadboard. As you can see, he ended up with seven modules that make prototyping faster and easier. At first glance some might not seem all that beneficial. For instance, making a board for an 18-pin … [Read more...]
[Parker] was in need of a Propeller development board to make working on his projects easier. More often than not, when he needed to prototype something, he would pull the only one he had on hand from his home made pinball machine, and replace it when finished. This was time consuming and cumbersome, so he decided he needed a better way of doing things. He looked into purchasing a Gadget … [Read more...]
The module works as a pass through, providing access to data and power lines for a USB device. [BadWolf] built it in order to sniff out communications between peripherals and the Universal Serial Bus. For now it just provides access to the different signals, but we think there's quite a bit of usefulness in that. First off, the power rail is mapped out to a jumper, making it dead simple to monitor … [Read more...]
We've got a couple of very high-tech shoe boxes in which we store our prototyping accessories. You'll find a collection of LCD modules, chips on breakout boards, switches soldered to homemade boards for easy breadboarding, and much more. That is assuming you can find anything in that mess of components. [Shahriar] took a different approach. He's mounted all of his prototyping gear inside of a … [Read more...]
