HOW TO – Build a PCB router
Jonathan designed a great printed circuit board router, he writes – “Printed circuit boards are usually manufactured by chemical etching (with iron (III) chloride or ammonium persulfate, for example). This is not very practical if only a few boards are necessary, because these etchants are messy and somewhat dangerous. PCBs can also be manufactured by “mechanical etching,” in which a trace is “etched” by milling away the copper along its perimeter. This requires software to generate a toolpath from the layout and a small CNC mill or router. Lots of companies make routers for PCB fabrication, but they are unjustifiably expensive so I decided to build one.” Link.
Here’s a detailed log of how to build a utility trailer. Includes a free AutoCAD drawing, materials list, parts list, as well as lots of pictures. Glen writes “I needed a trailer to haul around a snowmobile so I decided that I might get better use out of a general utility trailer instead of a snowmobile trailer. I checked the local trailer retailers and found that the going rate for a 5′ x 10′ utility trailer was around $1,300 Cdn. The trailers weren’t very strong and were made mostly from light angle iron. Always looking for a good project, I decided to build one instead.” 
Pat writes in with these week’s video from the Manufacturer’s blog! “…here is this week’s video of fiberglass insulation being made. The opening screen says, “Sand to Glass to Fiber Glass.” You’ll see here the process from sand to glass, and recycled glass, through 2500-degree ovens and eventually into fiberglass insulation. This is a substance that will be keeping us warner this winter, thought you might want to see how it’s made. The plant you see here makes enough insulation each day to insulate 250 homes.”

Here’s another great how to on converting an ATX power supply to a lab power supply, Abizar writes “Computer power supplies are US$15 but lab power supplies are US$100+. By converting the cheap (free) ATX power supplies that can be found in any discarded computer you can get a phenomenal lab power supply with huge current outputs, short circuit protection, and very tight voltage regulation.” 
“BURN STATION is a mobile copying station which – as it travels through suburban spaces – supports the free distribution music and audio. It is software as well as a local network. But above all BURN STATION is a social event which congregates people together to listen, select and copy net label and net radio audio files with a Copyleft Licence.” [
Pat writes in about his PEZ MP3 players, they’re almost gone! “There is still a chance to get a PEZ MP3 player in time for Christmas. I have several hundred of the little fellas in stock and ready to ship. After the recent appearance on Regis and Kelly they are selling quickly. So, if you haven’t bought one yet and you want to get in on this limited-run, first-edition, hop over to
