    PSU advice

    thanks Duke, I only got to see your reply here late last night and was disbelieving I'd wired the plug incorrectly.... well I eat my hat because you was correct...So used to following wiring diagrams I forget that I can get them wrong. Got it all sorted now and everything is correct. How do I...

    PSU advice

    thanks duke.... I've put the bypass in. I'm very confused though as I've wired the plug and socket and it appears it has put the to opposite sides? if i was to plug a plug in it now the neutral and live would not match? I've followed the diagram that came with the plug (wired these plenty of...

    Really liking the new look forum! :-) I've been really ill since last spoke here. I got all the parts for a light limiter circuit. I've been struggling though knowing what to trust on the internet.... seems a lot of different wiring layout etc....Maybe someone has a wiring diagram they can...

    Flippin eck I'm doing well on here today, where's that IT job ;-) Yes I'll follow your instructions and double insulate, I have grommets on order and will build the Lamp limiter tomorrow. Thanks!

    I'm not sure to be honest.... I think I am over compensating as this is new to me. As I said though all criticism and advice is welcome

    There is a 2.5a fuse between the switch and IEC Live leg. I was told 1.5a was correct but I only have this at the minute... I haven't put together a lamp limiter, I will look at this today and order what i need tomorrow (Payday) Sorry, again rubbish photo's, the other two leads are Purple and...

    PSU advice

    Yes, apologies, I only have my laptop camera to take photos with. I will try and address this for further photos. The gry and purple wires are soldered and then shrink tubed (but used clear shrink tubing). They are also then Tie rapped to the chassis (so no movement) but are insulated from the...

    PSU advice

    HI again. I hope it's ok for you guys to take a look at the PSU build so far, I am still awaiting delivery of the PSU PCB... but here is the transformer and IEC inlet with the primary side wired. Any advice is more than welcome.... criticism etc... At what point do I turn it on to test?

    Recording and repeating voltages

    I can use my field recorder ( it has 4 tracks) and auto levels function which i've used a lot with piezo discs.

    Recording and repeating voltages

    HI folks I've never used a microcontroller or programmed one. I have however done quite a lot of coding in my past. However I have no idea how to interface with a microcontroller even if i could write a programme for it... I have an arduino Kit somewhere which i've never looked at.... maybe...

    Recording and repeating voltages

    Hi all. I've been trying to research how to record and repeat sequences of voltages to no avail. What I want to be able to do is; use piezo discs and a signal conditioning circuit (courtesy of you guys a while back) to pick up vibrations from an area. then have a way of recording these and be...

    PSU advice

    Here is the schematic as requested. I also spoke to the engineer who has been able to instruct me on the wiring as follows; For a standard UK 230Vac supply, connect together the grey and violet wires and insulate the join. The blue wire is neutral and the brown wire is live (line) via the...

    PSU advice

    Thanks Harald. I'll endeavour to get those uploaded this evening. I understand your explanation to test for which to use. I see it is similar to how I had to connect the front of my bench power supply to make the 0v so i could run it at +12v/-12v

    PSU advice

    HI again. I'm steadily getting familiar with the psu parts and wirings. I'd like to check each step here to make sure i'm doing things correctly. First up is the transformer and making sure i'm reading it's wiring notes correctly. Primary Blue and Purple = neutral and connect to the Neutral...

    "The earth connection must be screwed to the case / chassis. This then becomes you primary earth terminal. All other earth connections should be to this point." Thanks Whonoes

    PSU advice

    Thanks Ed. From speaking to the engineer he says that the toroid comes with a it's own mounting. I should have this delivered by a week on Tuesday. I'll endeavour to post a picture of it so you guys can inspect and make sure it is correct.
