The PCB Racer is a fun and simple project to get started with the Bantam Tools Desktop PCB Milling Machine and basic electronics. It uses a pager motor to turn the drive wheel of a small race car made entirely out of double-sided FR-1 PCB material. Almost all of the parts for the car are milled with the Bantam Tools Desktop PCB Milling, including the chassis and the wheels. The remaining parts can be found at most electronics retailers.
Note: This project assumes you have basic knowledge of how to run the Bantam Tools Desktop PCB Milling Machine. If you're just getting started, check out our full library of guides.
The Bantam Tools Desktop PCB Milling Machine was designed to make CNC milling, and in particular making PCBs, easier and more accessible than ever before. We set out to democratize PCB production, putting a powerful tool within reach of engineers, artists, educators, students, and makers of all stripes. To some, however, the software choices available to create PCB design files seem prohibitive and difficult to use. Enter Patchr, innovative new PCB design software that employs an easy-to-use circuit design tool.
There’s a fairly new electronics publication called Diyode across the pond in Australia, and apparently, it’s “the first new magazine supporting electronics enthusiasts and makers that Australia has seen in 30 years.” Issue #8 just came out, and we’re thrilled that they did an in-depth review of our Bantam Tools Desktop PCB Milling Machine and loved it.
This post provides an overview of how to design and prototype printed circuit boards on a desktop CNC mill. Most students do not have access to a CNC mill in their electrical engineering or electronics classes. In most classes, students make circuits using breadboards, which allows them to make connections by plugging wires and components into a grid. This method is great for very simple circuits, but it quickly becomes messy as circuits increase in complexity, to the point where it becomes very difficult to troubleshoot.
It’s no secret that the Othermill is a phenomenal tool when it comes to milling custom circuit boards. Hobbyist, students, and professionals alike have shared stories of how the Othermill has significantly improved their workflow and allowed them to rapidly prototype like never before (read a few in the story links below).
We love hearing that, almost as much as we love supporting our users and helping making their experience as simple and fun as possible. To that end, we’ve been working hard to increase the support guides we have available. Here is a list of resources that we hope you enjoy and find useful as you mill PCBs on your trusty Othermill.
If you haven’t taken a minute (well, actually 1:36) to watch our newest product video, check it out now! It beautifully illustrates the possibilities of what you can make on the Othermill by showing off a multi-material case created for Other Machine Co.’s popular binary timepiece, the Nerd Watch.
If you’ve been following our blog for a while, you’ll be quite familiar with our use of the Othermill as an integrated tool for prototyping circuits. One of the biggest challenges in quickly prototyping electronics is the lack of available through-hole packages for use with solderless breadboards.
Though the Othermill is wonderful for a wide range of 2.5 and 3D applications, it still remains true to its roots as a very fine method to build and protoype circuit boards. We have a few trips and tricks we’ve discovered in milling boards that make the board-cutting process on the Othermill even more pleasant.
