Möbius Comic Strip is neverending fun
Jim Woodring created this Möbius Comic Strip, which wraps back into itself.
Sterling silver replicator block pendant
News of the big Stargate prop auction got me Googling around for entrepreneurs selling replica, um, replicators. Which search yielded this handsome handmade necklace from DeviantArt user DreamingDragonDesign. There’s also a 3D-printable replicator block on Shapeways.
Massive Stargate props auction
The news of this impending giant auction of original props and costumes from Stargate: SG-1 and Stargate Atlantis both thrills and saddens my inner fanboy: Thrills, because the prospect of owning, say, the original “travel” stargate, the “Thor” puppet, Daniel Jackson’s glasses, Teal’c’s forehead tattoo, Ronon Dex’s blaster, a mature larval Goa’uld, Apophis’s “serpent” helmet, a Zero Point Module, the original MALP robot probe, a bucket of Replicator blocks, an Iratus bug, a Jaffa staff weapon, a Zat’nikatel, a ring transporter platform, and/or the original SGC conference room briefing table is pretty awesome (even though all will likely sell for well more than I could afford); and saddens, because it means beyond any doubt that there will be no more SG-1 or SG-Atlantis. And, so far, I have to say, I’m not enjoying the more humorless, post-Battlestar Galactica approach of Stargate Universe quite as much.

Handmade LED wristwatch
Who makes an anachronistic-but-who-cares steampunk LED wristwatch from scratch? Eric Schleapfer does. Nice work! Yes, it’s an LED steampunk wristwatch! It uses the LED wristwatch board… The watch is constructed from a small piece of oak and pieces of brass sheet and tubing. I used hand tools, a Dremel tool and a cordless drill to shape and form each of the pieces.
Back to the watch. It keeps the time with a fairly pedestrian PIC16F628A. It has an internal timer that operates with a separate oscillator (which is the watch crystal in the lower right corner) which can run even during sleep mode. This is critical to keeping the power consumption low. When a timer tick occurs, it generates a wakeup event, and the processor can increment the internal timekeeping registers. The processor can also wake up when one of the buttons is pressed. When that happens, it turns on and starts multiplexing the LEDs so that it can display the time. After a short delay it goes back into sleep mode. I haven’t yet calculated or tested the battery life.
