Fresh hacks every day
[John] wrote in with a solution to a prototyping issue that has vexed us for quite some time. Above you can see the DIP friendly solution for dual-row pin headers which he came up with. With just a bit of easy soldering he now has a breadboard friendly device for prototyping.
He starts by soldering a dual row pin header … Read the rest
[Armin] recently pulled out his Commodore 64 and looked back on the projects he did as a kid. The surprising thing is that we’re not talking quite as far in the past as you might image. He was 13 in 2002 and the family didn’t have a PC. But more than a decade before his father had purchased a C64 … Read the rest
The 7400 Logic Competition has drawn to a close. The winners were announced and there are quite a few of them. There were fifteen first place winners named, nine second place, and nineteen third place projects. The bounty of quality entries is a testament to the popularity of the contest. It helps to have a wide range of prizes and … Read the rest

You’ve got to admit that custom milling your own wedding band is pretty hard-core. In this case [Jeremy Swerdlow] is making it for his friend, but that doesn’t diminish the fun of the project. After the break you can watch him mill a titanium ring and wrap it with a palladium inlay.
To solder palladium to titanium [Jeremy] would … Read the rest
Okay, we think it’s questionable when people say they have no problem soldering QFN packages, but BGA? Granted this chip has far fewer balls on it than many, but it’s still quite impressive that [Xevel] was able to solder this BGA breakout by hand.
The chip you see above is a TMP006 infrared temperature sensor from TI. [Xevel] picked … Read the rest
Whenever we hear about ECE 4760 we take notice. That’s because a ton of fantastic hacked together projects have resulted from the class. It’s offered at Cornell University and focuses on designing projects based on microcontrollers. We look at it as a ‘how to connect everything to your microcontroller’ guide. The good news for you is that 34 lecture videos … Read the rest
