Turning Your CNC Into A Vinyl Cutter

This may seem like a no-brainer, but it’s actually pretty easy to modify your CNC machine to hold a vinyl cutter blade in order to do stencils or even cut out vinyl logos!

[Jouni] designed a holder for a standard Roland vinyl/sticker cutter blade (replacement with 5 blades is about $10 on eBay). It’s made to fit his specific CNC which uses a 65mm spindle, with a 49mm mounting ring — but the file could be easily modified to suit others.

Simply clamp your plastic or vinyl onto a flat piece of wood, and get stenciling! [Jouni’s] included his .STL file on his site in case anyone wants to try it out. While he’s designed it for 3D printing, you could probably CNC mill it as well — which would kinda make more sense…

The Arduino Birthday Cake Is No Lie

Making someone a birthday cake is very thoughtful, but not if they are watching their weight. [MrFox] found a way around that: an Arduino-powered birthday cake. Even if you don’t mind the calories, an Arduino cake is a novelty and sure to be a hit with a hacker who’s another year older.

The cake uses a UTFT LCD shield which eats up a lot of pins and memory, so the project uses an Arduino Mega. A speaker plays the happy birthday song (which may even be legal now) while a microphone detects the birthday boy or girl blowing out the virtual candles.
