There’s a little problem with sending drones to Venus: it’s too hostile for electronics; the temperature averages 867 °F and the pressure at sea level is 90 atmospheres. The world duration record is 2 hours and 7 minutes, courtesy of Russia’s Venera 13 probe. To tackle the problem, JPL has created a concept for AREE, a mechanical robot designed to survive in that environment.
AREE consists of a Strandbeest configuration of multiple legs with a monster fan propelling it, and one can imagine it creeping over the Venusian landscape. While its propulsion system might be handled by the Strandbeest mechanism, it will still have to navigate and transmit data. We’re not sure how a mechanical radio wave might work–maybe like those propeller arrow-cutters that [Dain of the Iron Hills] busts out in movie version of the Hobbit? Chemical rockets that somehow don’t spontaneously ignite? Or maybe it can just “transfer all energy to life support” and AC the heck out of the radio.

GPS is really fun to play with in your projects. But when [Trax] decided to build a GPS chip into his design the fun ended abruptly. Above you can see the section of the board devoted to the hardware. Unfortunately this PCB fails to provide any GPS location data whatsoever.

So I thought about getting a pair of protective glasses so that I could safely stare at the sun during yesterday’s Venus transit. But then it was forecast to be cloudy in the afternoon (the event didn’t start until 5pm here) so I forgot about it and figured I’d try to catch it next time around (which is 105 years from now).
I went about life, ate some dinner, then grabbed my latest project and headed off to the monthly meeting at Sector67, the local Hackerspace in Madison, WI. Lo and behold I arrived to find this sight in the parking lot:
Sure, my priorities may have pushed the viewing to the side. But others made it their mission to see the once or twice in a lifetime event and I got to see it just for being in the same place as them. This is the meat and potatoes of Hackerspaces…. collaboration. A source of new ideas, motivations, and inspirations.
One of the members brought a telescope and went online to figure out how to safely use it for viewing. For about $2.50 he rigged up a funnel covered with a piece of acetate which interfaced with the eyepiece of the scope. The image at the top shows the entire sun, and even though some of the cloud cover can clearly be seen, there’s Venus, plain as day. The cardboard box is just providing a shaded viewing area around the funnel. As with most cosmic experiences, it surprised me by being way cooler than described. See a few extra pictures in the gallery after the break.
