Design and build a first clamp system

[feeds]

• [x] find a first remote
• [ ] find at least 3 remotes that should be compatible
• [x] can you do a "remote mockup"
• [ ] build a first clamp design, also this needs to be designed in CAD file as well

Hi @feeds Could you please elaborate on "remote mockup"? What do you mean exactly? Thanks :)

[feeds]

I was thinking that you can you just build one yourself where you have a feedback mechanism for a button, as this is something harder to test for when you are using remotes without anything connected to them.

For example, a 3d printed one you designed yourself with some simple mechanics so that there is a light/sound going off when the button was pressed successfullly -- you have those arduinos leftover from the individual project and buttons may be found maybe somewhere else at spot.

Ergo: By remote mockup I mean, a device with which you can test your setup. Could also be something else you come up with though

Probably a light is preferable given SPOT is an open office space ;)

thanks for the clarification! I'll see what I can come up with. Maybe that testing device could even contain multiple different button types with varying actuation profiles (sensitivity etc)...

Continue in next week. Also collect photos? Infrared camera?

So I designed a first prototype of the clamp. Public view access to the CAD design: https://cad.onshape.com/documents/b2c82a18f2539b479c082963/w/6f34726cc5d11dcb77d35405/e/55c9ca77e0fe928d4ac901c7

For now I designed two different type of clamp inlays (different shapes). (More to be designed later!) The idea is to have them easily exchangeable. To make them nicely attached there are two square holes to stick the magnets in, so that the parts stay together.

One side of the clamp will be fixed directly to the base plate. The other side should be adjustable. For this I designed a second fixed part on the left with a horizontal hole as well as an inlay padding for a a nut. A large wing screw would go through the hole and the nut, pushing the left side of the clamp into place. However I'm not yet completely convinced of this, since we'd need a way to fix the (dark blue) part to the tip of the screw in a way that the screw can still be turned without the part turning. I didn't find an easy way to do it. The only way I could imagine this would be to have some kind of joint soldered onto the tip of the screw. An alternative way of doing it could be to have the left and right side of the clamp simply completely symmetrical and instead two slits in the base plate for either of the side allowing to move that side of the clamp. Two wing nuts/screws would allow to easily fix that side of the clamp.

After discussion and some brainstorming today I revised the clamp attachment system. The clamp is now completely symmetrical. The adjustability relies on slits in the base plate allowing for a horizontal movement of one side of the clamp. The clamp inlay system relies the same.
