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.
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!
