Under a pile of junk in my room, I found two old 5.25" disk drives dating from 1984. Opened them up this morning; they each contain two of the most beautiful stepper motors I've seen in ages, and are old enough to have separate control boards - easily-human-alterable soldering - and lots of readably large labels on the PCBs for a human tester ("Bev", from the sticker!). Overengineered to the nines, from before these things were cheap.

Hurrah for not throwing anything away, ever!

Sorry to bother you, I just had to squee about this because the possibilities are distracting me from work :D


Mike Mc

Hurrah!!

I've salvaged about 20 steppers from various printers, floppy drives, scanners, etc. over the last few months. Now I just need to think of some use for them all.

RaygunGothic

20! That's some good salvage. Your own robot legion?

Mike Mc


RaygunGothic

Awesome.

Did I see you mention (somewhere else) that you go to London Hackspace?


mem

Do I sense a London swap meet in the making?   ;)

RaygunGothic

I doubt I have things anyone would want, unfortunately :( Good idea though, it would be a nice opportunity for it.

Mike Mc

Yes I do go to Hackspace. I'll be at the next one. I'd sure be willing to swap some steppers for something useful at Hackspace.

RaygunGothic

Ace! I didn't make it to the last one but I hope to make it to the next. I can generally be identified by my three cornered hat and by being a slightly-out-of-my-depth Arduino newbie. (Familiar enough with general electronics, but hadn't touched it for years - introduced to Arduino at the Hackspace-before-last - now I'm an addict and my sleep patterns seem to be suffering)

I recently bought a tube of ULN2004 transistor arrays for driving steppers, and I have rather more than I have steppers, I'd love to swap a few for a few if these would be useful to you. Otherwise I'm a bit short on cool stuff at the moment.



Mike Mc

Sure I can spare a few. I'll bring them along to the next one (presuming it's on the 20th).

RaygunGothic

Thank you! Although looking at the relative component values, I realise that is not a v fair swap so I shall have to try to bring some other things too, somehow. (any particular interests?)

Yes, they say the 20th. See you there.

Mike Mc

Not sure really. Bring what you've got and i'll have a rummage through the box.

RaygunGothic

Thanks for that! And it was really nice to meet you.

Mike Mc

No problems. Hope you find some good use for the motors.
