Fresh hacks every day
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 can't run a transparency sheet through … [Read more...]
The laser printer portion of this all-in-one machine gave up the ghost and [Entropia] couldn't get it working again. But the scanner was still functioning so he decided to separate the scanner from its dead printer module. The model in question is a Samsung SCX-4200. The design is actually perfect for separation because the scanner sits on top of the out feed tray of the printer. It can even … [Read more...]
[Brian] really liked his Samsung color laser printer right up until it was time to replace the toner cartridges. A full set of toner cartridges sell for about the same price as the printer itself, so [Brian] figured he could simply refill the toner in the cartridges he already has. The printer sends out the 'low toner' warning based on page count and won't print if the page count is too high, … [Read more...]
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 the photos in his gallery have comments that take us through his process. A laser … [Read more...]
