Fresh hacks every day
SMD components may be a little challenging for the home builder – even though the’re inordinately practical for homebrew PCBs – but if you play around with electronics and solder long enough, you’re eventually going to run into the horrors of BGA parts. Instead of convenient pins, BGA parts have tiny metallic balls on which solder is applied, a board … Read the rest
It’s not uncommon in cheaper devices to find a ribbon cable soldered directly to the circuit board like the one pictured above. Using a connector would have been a much more resilient approach, but adding parts adds cost. If you take a close look you’ll see things aren’t looking so great anymore. [Chaotic and Random] pulled this board out of … Read the rest
[GuShH] wrote a guide for making your own rosin-based solder flux. According to [Stephen] — who sent in the tip and tried this method himself — is works well, it’s cheap, but you will need to clean up a bit after using it on a PCB.
Only two ingredients are necessary to make your own liquid or paste flux: … Read the rest
One of the really cool things about the Nintendo Wii when it was first introduced was the ability to play GameCube games on it. This made it a no-brainer for a lot of folks to upgrade. But as the heyday of legacy systems fades into history, Nintendo decided this was no longer a selling point and stopped populating those components. … Read the rest
Kids learn better if they’re engaged in the topic at hand. [Todd] found something that has his son just begging to practice his spelling words each night. He converts them all to Morse code and taps each out on the Morse code practice station they built together. To start off Todd connected the keyer to his Fluke 87 meter, … Read the rest
[rue_mohr] is building a hexapod robot, and that meant he needed to tin a whole bunch of ribbon cables with solder. Using a soldering iron for this task would take far too long, so he built a homebrew solder pot to tin all those wires quickly. While [rue] was able to get solder on all those wires quickly, we need … Read the rest
We’re kind of surprised we haven’t covered this concept before since it only uses techniques that are commonly avaialable for home PCB fabrication. [Ray] made this solder paste stencil out of a sheet of copper using the same etching techniques you would for a circuit board. He designed and printed a resist pattern, with toner everywhere except the places where … Read the rest
