If you’re in to making your own PCBs at home, you know the trials of etching copper clad boards. It’s slow, even if you’re gently rocking your etch tank or even using an aquarium pump to agitate your etching solution. [cunning_fellow] over on Instructables has the solution to your etching problems, and can even produce [...]

Etching your own PCBs from copper clad board is nothing new, but the ability to make your own circuit boards at home is so useful it should be part of every maker’s repertoire of skills. The folks over at Hub City Labs in Moncton, NB, Canada put together a workshop covering the basics of home PCB manufacturing, [...]

What better way to spend a few months in the workshop than by heating Copper chloride to 400° C, building rotary spark gaps and 30kV capacitors, playing with high vacuums and building a very powerful laser? It’s just a day in [Jon]‘s life as he builds a DIY Copper vapor laser. Copper vapor lasers require temperatures of about [...]

For ham radio enthusiasts the art of building free-formed circuits using little bits of copper clad board is second nature. But [AndyDaviesByTheSea] figured out how to build your own tool to make the process much easier. First, here’s a quick rundown of the traditional build method. One base sheet of copper clad serves as the [...]

When it comes to making PCBs at home really quickly, there’s not much to improve upon with [Ryan]‘s bodged up Epson printer that prints an etch mask directly on a piece of copper clad board. Like most of the direct to copper PCB printer conversions we’ve covered ( 1, 2, 3 ), [Ryan]‘s build relied on an [...]

Former Hackaday contributor [mikeysklar] has been trying to etch a QR code into a sheet of copper. Although his phone can’t read the CuR codes he’s made so far, he’s still made an impressive piece of milled copper. The biggest problem [mikey] ran into is getting Inkscape to generate proper cnc tool paths instead of [...]

[Ben Ardwin] was asked by a friend to help fix an old motor. It needed a new set of brushes. They’re just thin pieces of copper that mount on the motor housing and contact the commutator. The metal is so thin he thought he’d try fabricating replacements by dissolving copper stock. This is not copper [...]

Hackaday reader [David] was looking for a cheap and easy way to spot weld copper tabs together. As he notes in his writeup, the properties of copper which are most enticing, such as high thermal capacity, make welding it all that more difficult. His home-brew method of spot welding is admittedly quick and dirty, but [...]

Reader [Andre] sent in a link which tells us all about this “cool” Copper Oxide Thermoelectric Generator. All you need is a bit of solid copper wire and a gas torch. Burn the wire so it gets a nice coating of oxide. From there, it is a matter of making the 2 sections of burned [...]

Here’s a step-by-step guide for printing etch resist directly to copper clad boards. Two methods of making printed circuit boards at home have long dominated as the favorites; using photo-resist, and the toner-transfer method. The latter involves printing board artwork on a laser printer and then ironing it onto the copper clad. We’ve seen some [...]

Building a great looking box for your projects can be a challenge. [Ken] boils down his process of building enclosures out of copper clad (PDF) circuit board material into an illustrated guide in case you want to try this for yourself. Why would you want to use PC board? The fiberglass substrate makes for a [...]

[Rhys Goodwin] has been working on a system to print resist onto copper clad using an inkjet printer. This is a toner transfer alternative as it still uses toner, just not quite as you’d expect. The first step is to modify an inkjet printer, separating the carriage from the feed rollers in order to increase [...]

6502 Gate Simulator Ever wondered what’s going on inside that chip as the program executes? Now you can take a look at the die itself with this visual gate simulator for the 6502 processor.

[imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance between the two pieces of copper changes, a measurement that is fairly easy to make with an analog to digital converter. [...]

[Tanjent] send us a link to his tutorial on the toner transfer process for fabricating circuit boards. We’ve seen a lot of these in the past, but we liked how his is straight to the point while also sharing several tips and options along the way. Notably, he ”tints” the copper clad before trying to [...]

We use the toner transfer method to fabricate printed circuit boards. The most difficult part of this is printing, ironing, and removing the paper from the toner that is used as an etchant resist material. [Mark Lerman] is developing a method to apply toner directly to the copper clad using a laser printer. Each of [...]
