Notes

I found a good deal on a USB Cordless Rotary Tool Kit Woodworking Engraving Pen DIY For Jewelry Metal Glass Mini Wireless Drill -from a seller on aliexpress.

I’ve wanted to try one of these for some time. For those cases where a Dremel, drill or router is just too heavy duty, for example:

  • adding finishing details, cutouts etc for electronic project enclosures
  • for scale model construction

The device arraived pretty much fully charged, so I was able to just slide in an attachment and start engraving. Not powerful, but easy to precisely control, which is perfect for the light and fine work I plan to use it for.

Specs

  • Attachment: 2.35mm
  • Clamp Depth: 25mm
  • Speed: 10000-15000-20000rpm
  • Power: 10W
  • Voltage: 3.7V
  • Battery capacity: 380MAH
  • Charge input voltage: 5V 2A

parts

The kit came with a very large number of attachments for engraving, polishing, cutting etc

LEAP is just my personal collection of projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:
