Fresh hacks every day
Second only to a lathe, a mill is one of the most useful tools to have in a shop. For [juppiter], though, a proper multi-ton mill would take up too much space and be a considerable investment. His solution to his space problem is actually very clever: he converted a small, inexpensive benchtop mill to CNC control, and put … Read the rest
A few weeks ago, we caught wind of a DIY version of ‘smart tweezers’ from [Kai]‘s workbench that are able to measure SMD resistors, caps, and inductors. At that time, [Kai] hadn’t quite finished the software portion of his build, leaving him with a pile of parts and non-working PCBs. The code is finished now, meaning [Kai] has a very … Read the rest
Unless you’d like to spend hours with a toothpick and a tub of solder paste, stencils are the way to go whenever you’re placing SMD parts. While most commercial and industrial SMD stencils are made out of laser cut stainless steel, [Peter] figured out a piece of plastic and a $300 craft cutter is equally well suited for the job.… Read the rest
We’re all familiar with overclocking desktop computers; a wonderful introduction to thermal design power and the necessities of a good CPU cooler. [Marcelo] wanted to see how far he could overclock a microcontroller – in this case an ATMega328 – and ended up with a microcontroller designed for 20 MHz running at 30 MHz.
To verify that his uC could … Read the rest
Over Thanksgiving, [Greg] had a little time on his hands and decided he needed an afternoon project. Having a few bits of plywood, an xacto knife, and some blue paint on hand meant a miniature TARDIS would take shape on his workbench. After finishing the model, [Greg] continued improving it with a blinky LED when the thought of adding an … Read the rest
This toner transfer method uses a different material than we normally see. The red sheet being peeled back isn’t toner transfer paper. It’s printable vinyl used for both the resist and the silk screen.
The application process is almost the same as any other toner transfer PCB fabrication material. The printable vinyl stick is first adhered to a piece … Read the rest
We’re not sure if there’s enough time to get a parts order delivered, but no geeky New Year’s party will be complete without a party buzzer that doubles as a Breathalyzer. The Buzzed Buzzer hides all of the necessary bits inside of a paper and plastic party favor. We guess it only buzzes if you’re over the limit? Actually … Read the rest
