That’s it – I’m giving up for the day. Twenty-one hours of searching online for a copper plating service that’ll give me PCB through-hole plating anywhere in Metro Manila yields nothing. And worse. Continue reading “Just give me some non-God-centric electroless copper plating!”

It is the day. Today is the day when we finally assemble the first of three motor controllers. Rather than ruin a perfectly well-etched board, we’ll experiment with a vise-mounted, handheld power tool to drill 0.8mm vias into our test board. The test board is a reject from a previous expose-and-etch attempt that had uneven trace widths.
I’m tickled by the thought of building a chair lift, if this CNC table project doesn’t pan out.
Much thanks to RS Electrocomponents PH for reducing the sheer physiological stress an order of magnitude, of my putting this CNC project together. You folks rock!
For anyone wanting to experiment with driving a stepper motor using an Arduino, you might want to try modifying the sketch below. Continue reading “It spins now.”
I’ve put in an order for a stepper motor and ball screw – quite excited and pleased that this online reseller (which we’ll name later) has responded. We’ll see if the experience of dealing with online merchants is any good; otherwise we’ll be continuing our walkabout across Binondo streets and alleys to find suppliers for these (and several other) key parts.

I’m starting this project with nothing more than an inexpensive drill press, a wood router, a Black and Decker RTX-1 and a few hand tools. This severely limits the precision of any metalforming work I can do. This means that I’ll need to rely on precision made parts – bearings, primarily, and a ball screw and nut – and use those to create a reasonably true frame with bearing rails for a hand-cranked, single-axis feed table.
