See that row of round cylinders sticking up? Those rest against the printed circuit board to prevent it from flexing while you are fingering the frets. Take a look toward the top of figure 1, which is the inside of the back of the guitar neck. The ‘bottom’ of the printed circuit board is now visible, held in place with two screws, one at each end, and a ribbon cable that attaches the board to a connector at the guitar-end of the neck. For this guitar (World Tour), there are 8-10 T-10 torx screws holding it together. In figure 1, the back of the guitar neck has been removed. To see the way the fret buttons ship from the factory, we need to open up the neck of the guitar. What do the existing fret buttons look like? There are the bare minimum of moving parts and zero alignment/assembly issues. This approach of using a flexible membrane and conductive pads is a super inexpensive method of making thousands-and-thousands (millions even?) of products that work well and are easily mass produced.
When a fret is pressed down, the membrane deforms, allowing the pads on the membrane to contact the mating pads on the printed circuit board, and the electronics are able to register the keypress. This all sits on top of a small printed circuit board that has matching conductive traces that align with the conductive pads on the silicon membrane.
The membrane contains two conductive electrical pads. On a standard Guitar Hero type guitar, the fret buttons (red, green, yellow, blue, orange) sit above a silicon membrane. Will be working on making an optical drive bay mount to hold industrial PSU's.Īready have some 120mm and 80mm brackets edited to work with this.Guitar Hero Mechanical Fret Button Upgrades What’s the deal with the existing fret buttons? I have to print this in two parts on the resin printer due to the X axis on the build plate being 120mm, and the X-axis of the bracket being 120mm (the slicing software says nope) My only problem right now is that my FDM printer is down while I need to replace the FEP on my resin printer.
Im using the Big Tree Tech SKR 1.3 (which has the same dimensions and mount locations of the 1.4) So, I was thinking about taking mITX or Micro ATX cases and using them as a single/multi printer controller and power housing unit.Ĭan use quiter cooling with more efficient airflow.įirst mod is a PCI bracket for mounting a control board. This is kind of a mod, but more of a project I am working on for using spare chassis for other things:ģD printer controllers usually are just mounted to the side of the printer, or some come in large controller boxes (with loud fans)
