I’ve heard from time-to-time, “The HobbyCNC guy got the pin numbers backwards”. Well, I grapple with that myself, so I get it. It’s not that they’re backwards, rather the board is ‘upside-down’. The confusion comes from the...

Why are there so many Guitar Hero fret boards? Great question, and I’ve asked myself that many, many times. I don’t have an answer, only an educated guess. Different styles of guitars on different game systems developed at different times by different...

I’ve enjoyed playing Guitar Hero (X-Box 360) for many years. I was never ‘good’, but I had fun. When my grandkids were old enough, I started them on the game too. One of my Les Paul guitars was missing notes and it was making for an unpleasant...

Inexpensive 3d Printer Filament Storage I found an inexpensive storage container for my 3D printing filament (8″ diameter spool). It’s a 2 gallon plastic paint bucket from Home Depot. It has a lid (extra cost) that seals nice and tight. Very little wasted...

Handy Measurement Jigs When I’ve got free time, I love to play around with 3D printing, my HobbyCNC DIY Router and electronics. There is that point in the design where the schematic (or drawing) needs to turn into a real, physical product, and, like most...

Anti-Backlash Improvement I developed a simple-yet-effective backlash preventer for my DIY CNC Router plans. The design uses a coupling nut with a flange welded on. This is fixed to the gantry. A spring is ‘pinched’ between this coupling nut and a simple square nut....

Arduino / GRBL First Test I’ve been planning for a while now to test the Arduino Uno and the GRBL CAM software with my HobbyCNC PRO board. I was certain it would interface, but I wasn’t keen on having to learn all the bits necessary to get it working....

Production Testing Assembled Boards I decided to offer assembled HobbyCNC PRO boards. As it turns out, not all of my customers are handy with a soldering iron, or they want their results quicker! So I build the boards, by hand, 10 at a time. Not a big deal. Testing...

Avoiding Bent Pins Sometimes the answer is in the trash. The background: while assembling a batch of HobbyCNC PRO boards, I was noticing how neatly the 23-pin driver chip dropped into the PC board. Then I had one chip with one lead, just one, slightly out of...
