An oasis in the desert is the quintessential image of salvation for the wearied wayfarer. At Burning Man 2016, Grove — ten biofeedback tree sculptures — provided a similar, interactive respite from the festival. Each tree has over two thousand LEDs, dozens of feet of steel tube, two Teensy boards used by the custom breath sensors to create festival magic.
Grove works like this: at your approach — detected by dual IR sensors — a mechanical flower blooms, meant to prompt investigation. As you lean close, the breath sensors in the daffodil-like flower detect whether you’re inhaling or exhaling, translating the input into a dazzling pulse of LED light that snakes its way down the tree’s trunk and up to the bright, 3W LEDs on the tips of the branches.
Debugging and last minute soldering in the desert fixed a few issues, before setup — no project is without its hiccups. The entire grove was powered by solar-charged, deep-cycle batteries meant to least from sunset to sunrise — or close enough if somebody forgot to hook the batteries up to charge.

The original story is in French, and the Google translate is very rough. Please forgive us if we don’t get this completely accurate.
While traveling through the desert somewhere in north west Africa in his Citroen 2CV , [Emile] is stopped, and told not to go any further due to some military conflicts in the area. Not wanting to actually listen to this advice, he decides to loop around, through the desert, to circumvent this roadblock.
After a while of treading off the beaten path, [Emile] manages to snap a swing arm on his vehicle, leaving him stranded. He decided that the best course of action was to disassemble his vehicle and construct a motorcycle from the parts. This feat would be impressive on its own, but remember, he’s still in the desert and un-prepared. If we’re reading this correctly, he managed to drill holes by bending metal and sawing at it, then un-bending it to be flat again.
It takes him twelve days to construct this thing. There are more pictures on the site, you simply have to go look at it. Feel free to translate the labels and post them in the comments.
Update: From [Semicolo] in the comments
You got the translation right, but there’s not just a swing arm that’s broken, there’s a frame beam broken too (not sure about the exact term, one of the 2 girder of the chassis).
He’s not far away but he has a lot of tools and other hardware that could be stolen if he leaves them unattended.
When you are in the middle of the desert, pretty much every solution to a mechanical or electrical problem is a hack. [Sgt.M] who was deployed in Iraq sought out the help of radio guru [H.P. Friedrichs] about a static problem he was having. When dust storms would blow in strange things would happen in camp. Humming and crackling could be heard and [Sgt. M] actually had an electrical arc from a lamp to his hand at a distance of about 2 feet.
[Friedrichs] helped him find the problem. Their antennae were acting as static electricity collectors in the dust. All that dust friction in the dry air constantly built up a charge. The solution was simple, discharge the electricity at the antenna when it isn’t in use. Several solutions are outlined on the page, so check them out.
