Cardboard tube battle
My local library picked up on the festive trend of Cardboard Tube Fighting.
The Boston Globe covered the preparations:
The group discovered cardboard tube fighting last summer in time to incorporate a bit of it into a presentation on Greek mythology at a reading program party.

As word of mock combat with reliably harmless weaponry spread among the townโs youthful warriors, Snoeyenbos and the Bookmarks seized on the fund-raiser as a chance to exploit their discovery of the fighting fad made popular by YouTube.
Saturdayโs event will feature one-on-one tournaments, guild-on-guild skirmishes (up to 10 fighters per team), โand an all-out battle for possession of the Royal Crown,โ according to the club.

Toilet paper tube faces
At last, something to do with that pile of toilet paper tubes youโve been saving all these years! (Thereโs no point denying it; we know how you are.) Then again, youโd be lucky to have the mad skillz of sculptor Junior Jacquet, whoโs made a career out of sculpting cardboard. His toilet paper tube faces, [โฆ]

Hereโs dad on the specs: Amplifier: In order to keep the design small, I am using a hybrid design for the amplifier. A [โฆ]
Handmade radios as objets dโart
Mister Jalopy hipped us to these amazing handmade radios from Tom Kipgen. The triangular wonder above is called Radio Moscow (โcause the finned brass plate cap Tom fabbed reminded him of Russian onion domes). As Mister J points out, for something this beautifully crafted, the asking price is a song. Wander the site for other [โฆ]
