DIN Rail Terminal Blocks

My shop-mate Stuart is a master prototyper. He frequently uses Phoenix Contact DIN rail terminal blocks for wire-up.

Taking a page from his book, I got my own set of Phoenix Contact DIN rail terminal blocks (3044102):

Terminal blocks make for easy changes. The red bridge-bars create busses with as many connections as you need. You can easily probe any point in the circuit. Everything is bolted down to the chassis.

Connectors may seem like an insignificant part, but these will really help.





Welding 3D Printed Steel

My shopmate had a TIG welder here the other day.

I took the opportunity to try welding the 3D printed metal parts I made last year:

These are intended to be coil holders, so I installed a 40 turn coil prior to welding.

Mike welding the halves together:

We used no filler rod on the theory that the infused bronze would melt and form a braze of sorts.

It worked very well:

The coil insulation didn’t survive: The coil is conductive to the casing.

I’m encouraged by the weldability. I am ordering more test parts to keep pushing this approach.
