Good, maybe the glue makes it look odd on the picture. It can be tricky to get the thicker wires to heat up properly - risk of cold solder joint.

In the interests of completeness of my build log and in the hope that it may help demystify building your own power supply here are a couple of videos of my power supply build. Although it is obvious to me, I will point this out for any with less common sense - working with electricity, particularly mains can be very dangerous. If you want to build your own psu then you can take it from me, a totally amateur, that it is perfectly doable if you ask the right people the right questions. Please post your design and invite comment before embarking on a project like this. You need to consider what the right transformer, rectifier, capacitors and fuse will be before starting and do your research, because connecting it all up wrong will be disastrous. Thanks to Dean, Clive and Barry in particular (as always) for the tips and guidance. Ps any comments on my very basic explanation in the second video (about 12mins in) will be gratefully received although I except from the outset that it is basic!!

Hi Joe,
First off, thanks for the fantastic build thread and video logs - keep them coming please! I've been getting more seriously into the initial design phases, had made some starting choices, then came across your build. Looks to me like you've encompassed the majority of the good advice out there, and then some more! I suspect when I get to a final design, it won't look too dissimilar to your own :)
Secondly, enjoyed watching your video this morning over breakfast - very well explained. Hadn't ever considered that the voltmeter was measuring RMS so UK mains peak-to-peak is sqrt(2)*240V. Only comment is that sometimes the audio balance in your videos is off - loud music, quiet talking! May just be me!

Hi everyone, I've managed to get a working mockup of the e-stop circuit together... another little video:

As always any comments gratefully received!
Can anyone explain what this is?? https://uploads.tapatalk-cdn.com/201...dd6ff766bc.jpghttps://uploads.tapatalk-cdn.com/201...cb1f8c5525.jpg
That is an interface converter that transforms a 0-10V analog signal to 0-20mA
This is it http://uk.rs-online.com/web/p/signal...oning/4184859/
I think they are used in industry to remote measure sensors etc over a two wire system like this;-
