IPhone tripod mount

I milled down two short bars of ali and put 45° troughs along one side. I drilled the bottom of one (opposite the trough) at 13/64″ and sank a 1/4 20 tap into it, to fit my tripod. At an eyeballed centre of a long side of each, I drilled 4.2mm and tapped to 5mm. I borrowed the taps for that. Using really good tools allows me to fake competence, or at least I am told that by someone I once thought was competent.

To join the two bits I laser cut 3mm acrylic into a rectangle with a slit in it. It holds my iPhone at a flat angle and will expand or contract if I change phones. I have some 5mm bolts in there which makes me happy because I stole them from !competent_guy. Little victories.

I need to add in foam or rubber between the jaws, to hold the phone sideways. There’s a lot of bend in the acrylic, so I could make it stiffer or make it out of metal. I need to do one of those things.

K8055 USB board

I picked up one of these in the trove at Makespace, thinking it was a cheap board, and it turns out to be a nifty bit of kit I can use for testing. If it were both expensive and useless to me, I’d return it, but I have plans for it in testing Itchy. I’d like to be able to see a slowed-down schem of the Gcode, f’rex. Outputting directly from my computer to an external board is a goal, and this is a step along the way.

Making it work on Arch was not a problem. Making it work as described on Arch was pretty horrible. In fact, I failed at just about every point.

The only available package is moribund, which at least means I don’t have to keep it updated. Make Install was not my friend but I stripped out the default install path and put in the correct one, then kicked a few things around. I wish I could remember what.

Then I entirely failed to make udev play happily. USB Device. Udev. I have a USB device. Is it devicing? Is it hell. I don’t know if it is because I run k8055 and that tries to take the device – Arch does not have the usual installation paths for everything, so there could be something seriously funky going on. I think it’s just malconfigured, though. I am just as likely to have fucked up small as big.

It had the same error message when I had the wrong group name as when I detypoed, so something is finding the rules and failing to pass them. Currently I can work with sudo or sticky bit. Neither is ideal.
