Woohoo! New product in!

Friday, April 16th, 2010

I sold out of my first product, a power supply for a solderless breadboard.  So I added a few features, ordered a new run of boards, and ordered a whole bunch of parts.  The PCBs came in last week, in a nice, v-scored flat pack:

That’s a 5mm LED next to it, for scale.  Here’s what the kit looks like assembled:

Want one?  It’s cheap–it’s just $4.99 over at the store.

Lots of time has passed…a little progress

So our camera bit the dust shortly after the last post.  Since then, I have mounted the supports for the x-axis lead screws, put the gantry together, and done a few other things.  First, the assembled gantry:

And now, to slide the gantry on to the base.  I ran into a minor problem here–the gantry is about 1/8″ too narrow.  Fortunately, the 1/2″ MDF has just enough elasticity for me to force it onto the track.  It might actually be a good thing–I don’t have to worry about having enough tension to keep the gantry in place.  I will have to add some reinforcement to the vertical sides of the gantry at some point, to make sure I don’t end up breaking them.  Of course, from what I’ve heard, all it has to do is last long enough to cut the pieces for my next, better CNC machine!
