Nice. Now all it needs is a drill and sander so you can feed it raw lumber.

It would be cooler if it didn’t use an inkjet print head, IIRC most wooden nickels are burnt with the info, I’d have experimented with burning in the image somehow, perhaps a ‘print head’ made with a heated matrix of pins? Or at least burn in one side with the machine info while variable-printing the back.

Maybe they were avoiding smoke. Besides, woodburning heat would be harder to manage, I guess.

It might be cool to do something similar with clay poker chips, but mill the design into the surface.

Beautiful machine!

i’d spend a couple of quarters!

Awesome! I’ve been looking to make a contraption like this. Where did you buy the helical flex coupling on the stepper motor?

More of a “lookie lookie” and no sourcecode, schematics, howtwo.

Neat, bot not worthy of hackaday release the code, drawings and other stuff.

psh, we don’t need the details to admire his workmanship! seriously, it’s a well-designed machine and works flawlessly, love it.

dave: the helical flex coupling on the stepper motor can be bought from McMaster-Carr; they are listed under Heavy Duty Bellows Shaft Couplings.

All the source code is available over at the Parallax web site, I guess the link didn’t make it into the article. http://www.parallax.com/tabid/769/Default.aspx

There is a lot of other information there too.

I don’t have any drawings of schematics, I just don’t work that way most of the time. If any body wants details though just let me know.

Ooops, should have added good post! Waiting for your next one!

Shame the Parallax printer kits are NLA. Would have rather liked to have a play with one of those… :-(

Oh well, there’s always the option of using a variant of Sprite’s “inkjet stamp” hack and a HP #40 cartridge…

Just as a note, this does not use the Parallax inkjet printer kit.

The inkjet head is pulled from an old ThinkJet and the head is driven directly from the Propeller chip. This is something that anyone can build today and you don’t need to buy anything commercially and you have a lot more control over that the head can do than with the Parallax kit. The code I have on the Parallax website for the Propeller chip would likely get someone started. Mike
