  1. I posted a "fix" for a Mac 250 with a similar error, the wireing (running in temp protective sleeve) behind the lamp had become brittle and disintergreated. The wires connect to a thermal switch, which I think detecta a "true hot" condition. I replaced the wires and sleeve. All good.
  2. Just an update to this. I bought the ebay one linked above and it fitted perfectly. It took a week or so to arrive, but I now have all 12 channels working again. Thanks again, Blue-room expertise triumphs again.
  3. Sorry for the poor picture. I was rushed for time due to "darling daughter 2b" arriving unexpectedly. They look like what I need, Thank you.
  4. I use an ancient ECS Apollo JDR 12ch dimmer rack that is missing one of the bayonet type fuse carriers,(30mm x6mm fuse) I've tried a few similar looking fuse carriers, but they dont fit maybe I need an "imperial" one? Any ideas before I start taking the dimmer apart to replace the whole fuse assemby (of course, the rack is screwed to the wall in the darkest most inacessable place)
  5. I would test as for an extension lead, as well as checking physical condition.
  6. I'm unfamiliar with these units, but I had a "HOT" error on some Mac250s that turned out to be heat damaged wire behind the lamp. IIRC itthere was a thermo switch, but the wireing had crumbled to nothing.
  7. No simultaneous Tx/Rx, and I havent tried it with other BT devices nearby, but I was suprised that it connected to my headphones so easily as they dont have a "pair" button.
  8. I struggle with hearing loss and tinitus. some age related and some brought on with an infection. Wearing a headset and trying to listen to a show and block out people talking in the tuck shop behind me is awful. I dont have BT equipped HAs, but might enquire if I can get an upgrade next assessment. Having only just become aware of bone conduction headphones, I bought this. https://www.amazon.co.uk/dp/B08FT7HJW7?psc=1&ref=ppx_yo2ov_dt_b_product_details Which magically pairs with my cheap bone conduction headphones. https://www.amazon.co.uk/dp/B0CD2K7M1R?psc=1&ref=ppx_yo2ov_dt_b_product_details I havent really checked battery life out yet, but with a bit more experimentation its a possible solution.
  9. I built a UK101. 6502 microprocesor running at 1MHz( could be persuaded to run at 2MHz). 1KByte of ram (expandable to 8K on board) 2K Byte of Video RAM.... Around 2,000 solder joints IIRC.
  10. I was an avid ETI reader, also Everyday E and ocasionaly Elektor.. I didnt have a lot of disposable income, so built alimited number of projects, Did BSc in electronics at Uni, but got sidetracked in to computers... PET, TRS80, UK101... Really miss Maplin, perfect place to pick up some bits on a Sunday afternoon.
  11. I'll leave it to someone with more experience to sugest a better way, but I dont think the linked device will work. There is a huge difference in signal levels between a dynamic moving coil microphone and the output of a mixingdesk. I'm pretty sure the desk would swamp the transmitter even with the gain turned way down.
  12. I helped with avery amateur production some years ago, Like your idea the arrow was mimed at the bow, the target arrow was concealed behind the target and pushed forward (by elastic) through the target when required.
