Hawaiʻi's Technology Community

The Amperage Pedal is now on Kickstarter! - Our team would greatly appreciate your help in getting the word out - or even better - making a pledge! The product is an example of what desktop manufacturing can achieve - quality products, made locally, that are affordable. We used a Shapeoko CNC milling machine and a Replicator 2 3D printer in the process. They're amazing tools. And an Arduino is at the heart of our product. Three of the team members live on Oahu and our engineer lives on Maui - Thanks in advance from the North Shore Guitars team...

Thank you for sharing the details. We often see 3D printing used for prototyping. Its really interesting to hear about its use in actual products. I've heard that movie costume designers have also taken an interest.

Sorry for the delay Daniel - I used the 3d Printer to printer an internal mounting system that hosts either an Arduino Uno or a Mega (same mounting holes on both). Because of the sub-millimeter precision of the printer it simple rests inside the enclosure with legs and is pressed tight when the lid is screwed on (and it's contoured to the lid btw).

Even more useful was the USB jack cover....It let me put a square peg (the USB jack) into a round hole - and look good doing it. Ever try to put a square hole in an aluminum enclosure? You need an expensive tool that does only one thing. Makes square holes. I opted for an expensive tool (the 3d printer) that can make all kinds of things. So, I can drill a 3/4" hole in the enclosure, centered on the USB jack then use a nice press-fit cover to fill the hole and expose only the USB jack.

I also used it to print plastic washers that prevent the footswitches from digging into the enclosure and damaging the paint. And all of those parts are color matched to the enclosure color. During prototyping the printer made 5mm tall washers because I bought potentiometers whose shafts were too long. The 5mm circular rings were used to drop them. I also printed some led clip-rings when I purchased the wrong size for the prototype. Instead of having to re-order (shipping cost - for a 15cent part?)  the right parts for sn#1. When I did the ordering for sn#2 I learned from the mistakes and got the correct parts.

Very useful tool...I'll be printing entire enclosures for custom midi controllers....but on the Amperage Pedal I wanted 'standard' stuff that guitarists are used to.

It sounds like a very interesting project. Which components were 3D printed?

Best of luck!

Link Fixed! - I hate when that happens - Thanks Joseph!

Your Kickstarter link is wrong...
