A customer sent these photos of a 3D printed enclosure for the bat detector kit I sell. Looks really great! Apparently their local library printed the file for free!

I've been working a bit on laser cut maps recently. As I'm trying to complete the #lakedistrict #wainwrights I created a map to highlights ones completed. #hillbagging. Quite pleased with it in the end! I do have a few for sale on my Etsy shop: www.etsy.com/uk/listing/4...

What kind of evil person designs a breakout board with a Grove I2C connector, supplies a Grove cable, and then totally changes the pins so it wont work?.... grrr.

Wanting to take your shed off-grid? - Then maybe our PV system kit can help you. It was originally designed to be used on the "Intro to solar PV" courses I run. www.curiouselectric.co.uk/collections/... Note: You still need to supply the solar panel and the battery!
