Hackaday Prize Entry: A Simple CNC

Posted on July 15, 2016 by Brian Benchoff

3D printers are all the rage, but there’s still space for more traditional CNC machines. For their Hackaday Prize entry, [Andy], [Tim], and [Chris] are building the Sienci Mill – a simple desktop CNC mill that’s able to cut drill and carve everything from wood to circuit boards.

As far as desktop CNC machines go, it doesn’t get much more simple than this. They’re using steel plates for the rails, NEMA 17s for the motors, and a simple stepper motor driver Arduino shield for the controller. The more complex parts are 3D printed, and the BOM doesn’t add up to …read more

Hackaday Links July 10, 2016

Several years ago, Iran used GPS spoofing to ‘land’ an RQ-170 Sentinel drone operated by the US military. Why is this interesting now? Because this week Pokemon GO was released. It’s a mobile, augmented-reality game that forces you to walk around your neighborhood to catch Pokemon. Apparently you can capture a Mewtwo if you make it to Area 51, Groudon near any volcano, and Deoxys is aboard the International Space Station. In the next week or two, someone will figure out how to spoof the GPS location on a phone to catch rare and legendary Pokemon. This will happen. …read more

A CNC You Could Pop-Rivet Together

Posted on June 23, 2016 by Gerrit Coetzee

You have to be careful with CNC; it’s a slippery slope. You start off one day just trying out a 3D printer, and it’s not six months before you’re elbow deep in a discarded Xerox looking for stepper motors and precision rods. This is evident from [Dan] and his brother’s angle aluminum CNC build.

Five or six years ago they teamed up to build one of those MDF CNC routers. It was okay, but really only cut foam. So they moved on to a Rostock 3D printer. This worked much better, and for a few years it sated them. However, …read more

How Did Pocket NC Survive and Thrive?

Posted on June 1, 2016 by Gerrit Coetzee

We had a chance to talk to Matthew Hertel of PocketNC at the Bay Area Maker Faire this year. During the conversation, he answered some questions I’d had about the project since I saw it on Kickstarter, and told a cool story while he was at it.

When the Pocket NC 5-axis Tabletop CNC Mill KickStarter came out, I immediately chocked it up as a failure out of the gate. I figured that there would never be a single delivered unit. It just seemed too impossible. The price was too low for a machine with that many large machined aluminum …read more
