Tonight, I did some prep work on a new EasyDriverÂ (on breadboard) that I ordered for an upcoming project. I mounted a 4-pin Molex Floppy connector for the motor output, and pin-headers reversed for breadboard mounting.
I also milled the gear off of a scrap stepper motor and built a coupler to a fancy leadscrew I had laying around. The leadscrew in question (pictured foreground) is about 9″ long, has 5 starts (5 parallel sets of threads) and has a twist-rate of 1 inch per turn (one TPI). Â The screw is further teflon-coated and uses a (probably Delrin) plastic nut.
Brandon questions if “thatÂ wimpyÂ stepper” can drive such an aggressive leadscrew, but I don’t think it’ll be a problem. Â If it does become a problem, building a new coupler (or finding a motor that has the same shaft size) shouldn’t be hard.
Jason notes that I forgot to post a photo of the other Mendel parts I’ve been building for the MakeryMendel. Â Below are photos of a stainless steel heater tube (the one that I didn’t ruin by welding a drillbit to the inside) as well as the “order form” that Brandon sent me. His drawings aren’t anything fancy, but we seem to have gotten the job done. Â For scale, the bushing in the photo is 1″ OAL, and the threaded rod heater is 1.5″ OAL. Â The picture with the fire is a prototype plaster bushing that we were testing. Â It’d probably work, but we dried it a bit too fast and it developed a nasty crack.
I’ve started to accumulate quite a heap of old smartphones, and would really like them to either get useful or get gone. It was my initial intent to “simply” hook one up as a networked webcam, and have it serve images via HTTP, not unlike the units sold by everyone from Axis to Panasonic. Â Sadly, however, this proved more complicated than I’d imagined.
After quite a bit of procrastination and some help from the guys down at the Makery, I found a package called WebCamera Plus, which only partly fit the bill. Â Half of this packages’ functionality requires a client installed on a PC, where the actual web serving happens. Â Without that “server” PC, the best it can do is FTP photos out on a timed basis.
Adding insult to injury, about the time I was ready to bite the bullet and spend the $20 on this thing, the company sortaÂ disappeared. Â On the upside, the company’s website did resurface a few weeks later, with the software now priced at $9.99. Â The decision had already been made, however, to go in a different direction.
Well, as of today, the Omaha Maker Group officially has a space. Â Keys to the new digs were picked up tonight, and the preparation and move-in begins tomorrow. Â The first official meeting at the new space is on Tuesday, March 8th.
