It’s fair to say that one of the biggest advances for the electronic constructor over the last decade or so has been the advent of inexpensive small-order PCB manufacture. That …read more Continue reading Never Drill In The Wrong Place, With This Camera!
Making PCBs isn’t always just about getting nice copper traces on a lovely fiberglass board. There’s often lots of drilling to be done! This PCB drill press from [w_k_fay] should …read more Continue reading A Nicely Accurate PCB Drill Press You Can Build Yourself
Making PCBs with the toner transfer method has been around since you could buy your traces at Radio Shack. There are a million techniques for removing copper from sheets of fiberglass, from milling to using resist pens, to the ubiquitous laser printer toner transfer. Here’s a technique we haven’t seen before. [Darko Volk] is calling this ‘chemotransfer’. It’s mostly a laser printer toner transfer process, but the toner is transferred from paper to copper with the help of a special mix of solvents.
This chemotransfer process is almost identical to the usual process of making a toner transfer PCB. First, …read more
There are two types of people in this world: people who think that PVC is only suitable for plumbing, and people who don’t even know that you can use PVC to carry water. Instructables user [amjohnny] is clearly of the latter school. His PVC Dremel drill press is a bit of an oldie, but it’s still a testament to the pipefitter’s art. And you can watch it in action in the video embedded below.
Things we particularly like about this build include the PVC parallelogram movement, springs around tubes to push the Dremel head back up, and the clever use …read more
