Thought I'd share a bit of what what I've been up to.

I got inspired by Sean Hodgins (on twitter) with a jig that he made for soldering headers perfectly.

Then I wondered if I could could do the same with a little board I've recently made, that allows me to control a load of external Relays etc (it's a 16 bit shift register, nothing posh)

Once picture attached in this one, another in the next post. I'll also post a link to my fusion360 folder.

here's another. not sure why they are coming up upside down.
