Fresh hacks every day
[Jay] was looking for a way to make his own vias on homemade double-sided PCBs when he stumbled across this post from about five years ago. The technique shown here makes mechanical vias and was developed by [Retromaster]. There’s no soldering involved, instead he uses some solid core copper wire and a press to crush it tightly against the board… Read the rest
[Andrew Zonenberg] has crossed a line in his electronic hobby projects. The Ball Grid Array (BGA) is a type of chip footprint which most hobbyists leave to the professionals. But he’s learned the skills necessary to use them in his projects. Recently he ran a test batch to show off his soldering process and illustrate one of the errors a … Read the rest
Learning to lay out a printed circuit board takes some time. But after you’ve churned out a few it’s really pretty easy. If you find yourself at that point it may be time to learn about more complicated board fabrication. We think a good primer is this multi-layer PCB layout guide which [Rik te Winkel] recently put together. It’s one … Read the rest
[Philip] developed a method of tracking down the pins of a Ball Grid Array. He wanted to do so in order to add USB host functionality to his HP Jordan 720. The method doesn’t directly connect to the BGA but instead finds a via or other access point to serve as a solder point. He first looks up the … Read the rest
The Asus WL500GP wireless router runs Linux and has two USB ports. [equinoxfr] wanted to install audio support internally to the router though (translated). Luckily, it uses a VIA VT6212 4port USB controller. So, he was able to wire two more internal ports. A Brando USB soundcard is plugged into one of those ports and wired to … Read the rest
