Dino from Hack A Week posted his first project for April Fool’s day, “Screaming Altoids“: [via]
I decided to create “Hack A Week”!
This is no April Fool’s day joke, it’s real. I’ll be posting one project a week for at least the next year! Big challenge yes, but also lots of fun! Stop in and see the first project for April Fool’s day, “Screaming Altoids”.

I’ve made a half dozen battery-free crystal radios in about eight weeks. But I always wanted to try to stuff one inside of an Altoid tin for on-the-go. The short ground wire and long antenna wire that connect via an RCA plug, store neatly inside the tin. The 2000 ohm crystal earphone would fit in the tin if the long tube was chopped off. 200 turns of a 27 gauge wire on a 5/8” cylinder gets me tuning in the upper AM band. Perhaps I need to include a 3” copper ground spike to get a good ground in the field. Or would clipping onto a damp root be a better ground? Input?

User Alexdlp @ instructables.com build a wireless 2×16 character display on Altoids box. To achieve wireless connectivity he used an Xbee module and a suitable antenna. Check construction details on the link below. There are two unit one connected to PC and a remote one.

Check out this nifty touchkeyer (for CW or “continuous wave” Morse code) ham operator Jonathan Haynes ( KC7FYS) built into his Altoids-housed ATS-3b high-frequency CW radio transceiver:
I put whiteboard marker on my fingers and pressed them on a piece of paper to get this footprint. The idea of sculpting them from PCB material came to me when I was trying to sleep. Ha ha. Next time I’ll use thicker copper with a thicker substrate. [via]
