Fresh hacks every day
We think that anyone who’s done at-home PCB fabrication will appreciate the tidiness that [Fran] maintains throughout her etching process. She recently posted a three-part video tutorial which showcases her techniques. As you can see in the screenshot above, her habits reek of top-notch laboratory skills.
Regular readers can probably guess what circuit she’s etching. It’s the test boards for … Read the rest
The migraine-inducing image above is the product of [Rupert Hirst]‘s attempts at home PCB fabrication. He’s using the toner transfer method – printing a circuit on a piece of transparency sheet with a laser printer, setting it on a piece of copper clad board, and sending the whole assembly through a laminator. It’s a fairly straightforward process, but if you … Read the rest
A lot of the board houses out there including Seeed and ITead studios have a fixed size for circuit boards before the price goes up. A one-inch square board costs the same as a much larger 5cm x 5cm board, making panelized PCBs a great way to get more boards for the same amount of money. Trying to panelize a … Read the rest
Ever so slowly, we’re inching towards a world of Internet-based electronic design tools. The state of these tools, including Upverter and other cloud-based solutions, hasn’t been all that great until now; with any new piece of schematic capture and PCB layout software, the libraries will be woefully inadequate in the beginning. This is about to change, because circuits.io is now … Read the rest
[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
We’ve seen scores of floppy drives play music, but never before have we seen a project as clean as [Rupert]‘s Moppyduino. It’s an Arduino-based board that controls the stepper motors in six separate floppy drives, coaxing them in to playing music from a MIDI file.
The Moppyduino is more than just a convenient way to control the stepper motors … Read the rest
[Christian Aurich] wanted to use his Eagle CAD circuit board design in a proper CAD program in order to design enclosures. There are already a few options along these lines, but they didn’t quite fit his needs so he developed a script to import Eagle boards into FreeCAD. The script is packaged as a python macro for FreeCAD.… Read the rest
