The beginnings of an Aliens-style (except, you know, without all the actual bullets and killing and so forth) automatic sentry gun from diederick. The tracking platform is obviously flexible, but I think he intends to mount an AirSoft gun.
A couple of winters ago, when some friends and I were slogging up the roughly 2,000 vertical feet of Waterhouse Peak in the South Lake Tahoe area, snowshoes on our feet and snowboards strapped to our packs, we were repeatedly passed up by smiling telemark skiers, smoothly gliding uphill with skins on their skis. The […]
Zibri did some investigative hacking with the Force Trainer (brainwave controlled toy) and posted a basic interface schematic using a MAX3233 to interface with his PC via serial. It turns out the EEG headset is sending out data as ASCII characters @ 57600 baud – should make for some quick and easy hacking! Time to […]
From the MAKE Flickr pool Daniel sends pics of his laser-cut/engraved ouija board – the hand-painted fills add a nice touch!
Some years ago, a conversation with my old friend Billy Baque turned to the subject of adapting board games for sightless play. When it came round to Go, Billy mentioned having read of an antique Korean board, hollow inside and strung with wires along the lines of the grid, the wires being tuned such that each intersection produced a unique musical interval when a stone was placed upon it. Whether this was simply an aesthetic embellishment or a means to make the game more accessible to sightless players, he did not know.
No photos yet. That’s a homework assignment for the bubble chemists in the audience. But I couldn’t resist sharing my excitement over this paragraph from US patent 5246631 for glowing soap bubbles:
An example of practice of the present invention involves using a liquid dish such as LEMON JOY available from Procter & Gamble Company (Cincinnati, Ohio). Although the LEMON JOY may be diluted with varying amounts of water, it is preferred that the dishwashing liquid be used at full strength. Approximately 9 milliliters of CYALUME solution made in accordance with the manufacturers instructions are added to approximately 120 milliliters of the dishwashing liquid. Although this particular mixture may be used to produce adequate self-illuminated bubbles, it is preferred that 3 to 4 drops of glycerin be added to the solution as a bubble hardener. The solution is then ready for use to form self-illuminated bubbles.
I’ve never actually measured how much Cyalume (wikipedia) is in a standard glow-stick, but I’m betting you could come up with 9 mL of the stuff by cutting open two or three at most.
Stretta managed to build a fully functional (and apparently quite fun) foosball table from LEGO parts – My son is really attracted to foosball tables, and, if I’m honest, I’d have to say I am too. I considered the idea of buying a small, tabletop unit, but I was unsure how much use it’d see. […]
