They needed a place to stay on road trips and at music festivals. This teardrop camper certainly fits the bill. And it’s got a look that will make you proud to unfold yourself into the parking lot every morning.
Starting from a flat frame the camper skeleton was built up using plywood sides and cross pieces to help support the sweeping roof. It was then covered with 1/4″ Birch plywood which has enough flexibility to follow the contour. Inside you won’t find much in the way of frills, but the entire floor is a 4″ thick foam mattress which is a lot better that camping out. There’s a dome on top which can opens for ventilation and a hatch on the rear to carry some extras along on your adventure.
[Clement] and his friends were going on a long bike tour and needed a way to carry their gear along with them. They set to work and managed to build this cargo trailer from mostly reused materials.
The only part of this trailer that is reused junk is the connection mechanism that lets you attach it to just about any bike. That was made (presumably in a machine shop) to act as a removable pipe clamp, making it pretty quick to swap between different bikes. It has a universal joint welded to it so that the angle of the seat post won’t affect how the trailer rides.
A goose neck keeps the trailer far enough back to avoid getting in the way of the rear wheel. The mesh basket was made from parts of an old industrial machine. The rear wheel is attached with a swing-arm that has what looks like a rubber bumper to act as a shock absorber. But if you want to make sure a big bump doesn’t send your luggage flying, [Clement] included a picture at the bottom of his post showing a much nicer spring shock on a different bike trailer.
If you’re confused by the title of this post you must have missed the cargo bike that was recently featured.
[Imsolidstate] is working to add side turn signals to a trailer. These orange clearance lights are illuminated when the vehicle’s headlights are on to increase a long trailer’s visibility. They also blink along with the turn signals on the back of the trailer. A standard 6-pin lighting harness doesn’t support this functionality so the trick is to add them without altering the towing vehicle in any way. He’s using an ATtiny24 microprocessor to interpret the logic from the vehicle and then translate the turn signal and tail light data into a signal for the additional side indicators.
