Fresh hacks every day
[Henrik] really turned out a nice little Geiger counter board based on a cold war era Geiger tube.
It works in much the same way as other projects along the same lines. It does run on batteries if needed, which is no small feat since the tube wants high voltage to operate correctly. And the video after the break … Read the rest
It’s a stretch to call this one a hack, but USB thumb drives are around us constantly and we always assumed that the boards inside were machine populated (like with a pick and place machine). [Bunnie] tells us otherwise. He recently had the chance to tour a factory where USB flash drives are made.

[Limpkin] designs circuits for a living. This board is one of his recent projects, and although his skills are light years ahead of our own experiences, he did a pretty good job of explaining how he put this board together.
He was tasked with measuring the light intensity of two photodiodes. The expected impulses picked up by those components … Read the rest
The [Prutchi] family sounds pretty cool. [David], the father, is a well educated engineer, has 70 patents, and has written two books. On his off time, he has a passion for making experimental physics accessible to the average Joe. His daughter [Shanni] is a high school student who co-authored one of those same books, and helps conduct research in the … Read the rest
If you’re serious about astronomy these days, you want to have a computer controlled telescope. Although you can easily purchase a pre-made cable that connects the two devices, where’s the fun in that? [Charles], being an avid Maker, has created a nice step by step guide so you can build your own.
This is a great weekend project, and … Read the rest

Take a few moments and read [Jonathan]‘s first hand experience of a maker start up business that didn’t go anything like he had planned.
[Jonathan] thought … Read the rest
If you’ve spent any time at all laying out your own circuit boards we’re sure you’ve run into the issue of not having the right component or package available in the standard libraries. If it’s a common part, chances are the symbol definition will be there. But perhaps the footprint you want to use is missing? Here’s an easy to … Read the rest
