OpenBeam brackets (102643, 102632) are out of stock. This means we are also out of stock for OpenBeam precut kits. We are not sure when we will have a new batch of brackets in. Therefore we decided to create an alternative: the OpenBeam precut kit with XL brackets.
The OpenBeam T-brackets (102643) and L-brackets (102632) are out of stock. From our supplier we have not had a answer yet on when to expect these brackets in. They are working on a time table. Once we have an estimated delivery time we will let you know.
This means we are out of stock for the OpenBeam precut kit black (100540) and clear (100551) as well.
Since we now have an alternative for these brackets with the MakerBeamXL right angle bracket (101732) and the T-bracket (103004) we decided to create an alternative: the OpenBeam precut kit with XL brackets. We aim to have this online before the end of January 2017.
Since we are also almost out of OpenBeam feet and we order these from the same supplier we also changed from the OpenBeam feet (100966) to the vinyl end caps for OpenBeam (100977) in this precut kit with XL brackets.
Deskbreeze is a lightweight and simple wind tunnel for teaching aerodynamics to children and adults.
Last summer, Gerhard’s daughter attended a sailing course for children. She was six years old and would enter school the following autumn. She could not read and write and therefore had trouble understanding the written course materials and the graphics. So Gerhard thought about a vivid method to explain to her the basics of aerodynamics for sailing.
Gerhard built a wind tunnel of cardboard and straws, attached to a little fog machine. It worked well, but wasn’t perfect. Through several iterations he developed a stable and simple wind tunnel, into which you can put different objects. With a simple turntable and wires you can change courses and the position of sails, for example.
Deskbreeze uses fans and honeycomb cores to create a laminar flow, and dry ice for the visualization of the airflows.
You can move video and photo-cameras on a slider to make attractive recordings. Moving time-lapse recordings with a DSLR or arbitrary video-camera movements are the main applications of the kit. The kit can also be used for completely different purposes where linear motion is needed (see end of the video below).
Max made this project with selfmade custom lengths. The beams were 200mm and then cut to 185mm.
Max his tools: clamps and a hack saw.
“Hi, So I ordered another lot from chartup.com and when this lot arrived they were the new version where the centre holes goes all the way through. Excellent! I cut them to length using clamps and a hacksaw in my kitchen. Then tapped the threads using an M3 tap, a power drill and some bicycle chain oil. It all worked perfectly so it is possible without proper tools 🙂 Thanks, Max”
Unfortunately we discovered some 1000mm OpenBeam that have distorted ends. The tips were squeezed together as if they were handled by strong pliers on that end. Leaving the tips twisted and the holes oval instead of round.
We quickly inspected some packs and indeed found other beams that were distorted this way. This inspection also gave us the insight that it was a production failure rather than us packing the beams the wrong way. There were packs with distorted and non-distorted beams wrapped together. These tips should have been cut off in the production process.
Upon a closer inspection we have come to the conclusion that the distortion appears almost exclusively in the longer lengths OpenBeam. This means the beams of 600mm, 750mm, 1000mm and 2000mm.
Last week we sent an email out to the OpenBeam customers who possibly have bought affected beams from this batch. This way we can work out some form of compensation for these customers or simply replace the affected beams with good beams.
We are very sorry for this to happen. Naturally we are in contact with out manufacturer as to make sure this does not happen again.
