Now transform this!

This is the most useless piece of wasted technology ever; the "men's groomer" "as seen on tv" !!!!!! I've bought two of these, planning to build from them something more useful, that is a circular etcher / drill and a sort of sliding saw, to etch / smooth / saw materials like hardened paperclay, glass, balsa wood and terracotta; but surely I've presumed to be smarter than I'm in electronics..... So I'm stuck with these two pieces of useless stuff in hand; do you know how to get an etcher and a saw from these? I'm sure there're many smart guys here. This may be one of the smartest instructables ever.

Ok people, I think I'll figure it out myself...... Bye bye....

hi Jack. Well, I've thought to completely eliminate the blade (which is made up from trwo teethed bars sliding upon each other), and to exploit the cabstan sprouting from the little electric rotating engine held within the body. The blades are lodged into a plastic hood which is removable, the way we can see the capstan and the engine in the body stalk. The capstan is very short (thus, I think that the issue were that to toggle it, and to graft on the engine a longer thin piece of metal instead of the current capstan, 'cause I'm afraid that soldering another piece of metal upon the current capstan will ruin the engine). I'll add images; meanwhile, I guess that you could figure it out.
. A lot depends on the motion of the shaft. . If it rotates, then you might be able to make a small drill. Or a power source for another project. . If it reciprocates in and out, it might make an etcher or saw.

Hi. The shaft is rotating by default; it previously reciprocated through a rectangular adapter which was attached to the shaft through a cog; I removed the adapter and the cog, so the gear rotates freely. You can see the picture to the prime message of this sub-thread to which you replied.

this is what the stuff appears inside.
How does the blade mechanism work? thats what'll decide how the tools you make work?

Hi Goodhart. It runs on one AAA; and frankly, it doesn't trim even a single hair... It rather pulls 'em! I cannot imagine how people could buy these stuff believing they can actually cut anything.... However, I think that it could be anyway suitable to smooth / cut on green clay / paperclay, which doesn't need so hard pulls / pushes (a real etcher / drill can break clay, with vibration and pressure). That's why I bought 'em. I thought that one could be modified so that the sliding "blades" could act as a saw; the other, removed the tip, could be tipped by some rotatory cog, holding some drilling bit (I guess it could be made from a resin cone of sort, attached to a peg capped by a tiny plastic cog, whatever).

Yes, that sounds about right

what does that run on? One or two AA's ? or AAA's ? I would think it only just barely has enough power to trim a mustache.
