Fresh hacks every day
PC board houses are getting more accessable and less expensive all the time. Some of us are even getting very, very good at making our own circuit boards at home. There are times, though, when a project or prototype requires an extremely cheap custom board right now, something etching a custom board won't allow. [KopfKopfKopfAffe] has a unique solution to this problem, able to create custom … [Read more...]
[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. In describing the shortcomings of what's already out there [Christian] … [Read more...]
The prices for custom made circuit boards has never been cheaper, but surprisingly we've never seen a comparison of prices between the major board houses. [Brad] took the time to dig in to the price of 10 boards manufactured by Seeed Studios, OHS Park, and BatchPCB. He made some pretty graphs and also answered the question of where you can get your circuits made cheaply. [Brad] got the prices … [Read more...]
Despite what you may have heard, those 40 Watt laser cutters actually can cut out traces on your next PCB. Since he got his laser cutter a year and a half ago, [Rich] over at Nothing Labs has been trying to cut PCBs with it. Others have tried, usually by masking off a piece of copper followed by chemical etching. [Rich] wanted a one-step process, though, and his laser cutter really isn't up to … [Read more...]
Hey look, an Arduino without its clothes on. This one's just started its journey to becoming the ubiquitous prototyping tool. The image is from [Bunnie's] recent tour of the fab house where Arduino boards are made. As it says on every true Arduino board, they're made in Italy. [Bunnie's] trip to the factory happened in Scarmagno, on the outskirts of Torino. The process starts with large sheets … [Read more...]
This clock looks fantastic because of the glass PCB used for the build. This banner image allows you to see all the traces and components, but when it is lifted off of the desk surface the LEDs which make up the 7-segment digits appear to be floating. The concept isn't new, but it's a much larger format than we've seen before. When we first looked at [CNLohr's] glass PCB fabrication he was … [Read more...]
Ditch that old toaster oven and move to the next level of surface mount soldering with this vapor phase reflow method. [Ing.Büro R.Tschaggelar] put together this apparatus to use vapor phase reflow at his bench instead of sending out his smaller projects for assembly. It uses the heating element from an electric tea kettle to boil Galden HT 230 inside of a Pyrex beaker. There's a copper heat … [Read more...]
