[move] ;D Happy 4th of July to you guys on the other side of the pond! ;D[/move]

I don’t know where you live or what colors you have on your wires so it’s hard to guide you!

Thanks John, interesting! I noticed that it has the same author as the two articles I posted earlier, he must be an expert in reusing steppers! ;D

Not all are welded and not all are E I core, some are toroide transformers. Usually the secondary winding is the outer layer (on top) and can be removed and replaced with some effort. When removing a secondary its always a good idea to count the turns, this gives an idea of how many turns you have to put on to get a desired voltage (knowing the original voltage). If the core is welded you can still do this, it’s just like stitching only backwards! Some transformers just isn’t suitable for this kind of surgery like when they are molded in epoxy or some resin. Even these can be dismantled if left for some time submerged in paint stripper but it’s too much trouble unless the transformer is a very special specimen!

At least as little as possible, you never know.

Hi Chris, It depends on what kind of transformer you have to begin with and what you like to do (what you want to change). There are different ways to go about it, some harder then others.

Cool clock for a cool guy then! ;)

Hi Steven, Always busy with new projects, great work keep it up! ;D Just one caution, the NE555 might be toast at 18 Volts. Its maximum operating voltage is 16 Volts according to the datasheet. Take Care! ;)

Yes, that’s what I was thinking about. Not a bad picture, just small! ;D Let us know how it develops!

When I magnified the pic I could see you got it right! If you need it to push on both sides make the lever arm in one piece (U-shape) and put a hinge on the back of the press, something like this: The red thing is supposed to be a hinge, the blue is the lever and the view is from above! ;D

Another lever arm might not prevent the thing from sticking. The picture is not clear enough to show if any of the joints (screws) have some sideways slack, it should have because the distance between the two screws varies as the tool holder slides up and down. ???

It doesn’t look too bad I think! At least not where you have pointed the camera! ;)

Yes John, I think so too! ;)

Pictures pictures…. from the workshop! ;D

Yeah, the mechanical parts where fine but the scanner sent out smoke signals after the wall wart got faulty serving 30 Volts to the unit in stead of 16! A pcb with plenty of surface mounts got fried and I signed the death certificate immediately! I saved the plastic covers, the glass and the lid for a future project, a UV light box. B T W, 100 posts….. You are now a full member Chris! Congrats! ;D

Holy cow! :o If you throw away all those 386’s you’ll get plenty of room! :D

Improvise! ;D

Does this mean you will stop using your computer???? It probably radiates more RF than a bluetooth device. There is so much radiation floating around these days. All the power wires running through your house and out in the street. If your computer and monitor is properly grounded very little RF should leak out. When using WiFi, cell phones or Bluetooth there are antennas for the purpose of emitting RF around you house and through your head! ;) There are lots of fumes and gases in the air, why not smoke cigarettes too? ;)

Sorry, can’t help you there. I have no schematic for such a device.

I scrapped an old Mustek scanner a few weeks ago and I can see you could have use for some scanner parts here. Inside it was two fine rods and slide bearings to match! ;)

Hi Chris, May I suggest you build a clock radio for your bedside table!

OH NO, you shouldn’t use good parts for this. I just praised your way of reusing things and now you have exposed yourself! ;D

Yeah, let’s hope so.

There you are again, reusing things that someone else throws away! I think that’s commendable thinking! ;)

Is that a couple of timers….. ? ;D ;D
