  1. Well done @Crazy Al it's over 11 years since the design was started and well past the time it was migrated to SM components. Good luck with the migration and if there's anything I can do to help send me a PM. Although I no longer have access to EasyPC which was the original design platform, I do have Kicad.
  2. Wood should be OK, but I think even galvanised tube will suffer end damage on concrete. A lot less than aluminium but the underlying steel isn't hardened.
  3. One thing to be careful of when storing ali tube vertically is end damage. If the floor is concrete put down some padding (6mm rubber sheet is ideal) otherwise the tube ends will suffer.
  4. So, an M16 connecting nut would be a good place to start. I'll be in the Inverness Men's Shed on Tuesday and I'll see what we've got to hand.
  5. Is this what you are looking for? I turned it many years ago from a chunk of hex bar. The hex end was drilled & tapped to M10 with a bit of studding screwed in (with Loctite). You can make the stud any size you want. If you have a Men's Shed in your locality, give them a call as it's something they should be happy to knock up for you (we do this sort of thing every week in our Shed).
  6. Get in touch with Brian Summers, he's the most likely source of manuals etc. http://www.tvcameramuseum.org/
  7. Sorry I missed this post. here's a link to the zip file for version 1.4.
  8. In my last job before I retired we used something very similar to this: https://bownetcms.co.uk/shop/data-cabinets/19-wall-box-accessories/power-distribution-units-pdu/uk-13a-bs1363-socket-12-way-vertical-rack-mount-pdu/ Quite expensive but very robust. Oh, and it was nearly 20 years ago!
  9. Oooh err, I still have a 2020/2021 trade catalogue. It's probably worth putting it on Fleabay! Seriously though, this is very similar to the box we used for Bluecom and will probably do the trick: https://cpc.farnell.com/multicomp/mcrecs80/case-aluminium-80x108-5x45mm/dp/EN85413
  10. You might find that adding a couple of general purpose transistors improves the performance.
  11. Yes, the PIC12F629 is still available. You could substitute it with the PIC12HV629 which has a built-in shunt regulator so the 5V regulator can be dumped.
  12. Sorry about the delay in replying here but I have been "sans computer" for a week (WiFi problems). Anyway, in true Blue Peter fashion "Here's One I Made Earlier". EN2014050261.pdf
  13. Congratulations on your retirement, it sounds like you will be as busy as ever.
  14. If it helps the small blue pot in the second picture is marked "503" which means it is 50k.

    Sound to motor!

    Thanks for that link. I managed to track down an article I wrote for Television magazine which was published in February 1977. I thought I would never see it again!
