  1. Welcome aboard the happy ship. ray
  2. Hi Adrian, Welcome to the lounge, All very friendly here. I'm only in March if you want to chat. Have you thought of joining the local club? cheers
  3. May I suggest that you take yourself down to a local large garden centre that has a tropical fish concession company on site. There you will find a box of parts specifically designed and assemble for taking power from indoors to the pond etc. Supplies up to about 2000 watts and comes with an ip65 multi outlet. The connection indoors is RCD into a convenient socket. ALL approved and meets Part p etc. However the kit is not cheap. Rcd + indoor cable + wall conector + Armoured cable (15, 30 or 45 metres) + multi outlet + 'safety items' about £200. It even comes with a long series drill for the hole through the wall.
  4. Manock101, I would suggest you go to "The Open University" website and go through the self assessment tests working your way up until you fall over. Each set has a reading list appropriate for that subject/level. A word of warning.. If you self assess M205 then be prepared for a shock. This course is a prerequisite for subjects like Gravity/Relativity/Understanding Space and Time. Even the OU admit this course is a killer. ray
  5. Hi there, Have a look at this site :- NASA's Radio JOVE Project: Home Page There is also the Inpsire Project and SIDS that may take your fancy. They can all be accessed from the Jove site. Don't be put off by the antenna, mine is stretched along just above the ridge of my house.
  6. Hi there, Yes I'm still here. You can get me at marchnites@yahoo.co.uk I cancelled my website as it was imposssible to edit. The provider was most unhelpful and none of their suggestions worked. Can anyone reccommend a good freebie provider? cheers Ray
  7. A suitable holder and put it in the dew shield it is. Thanks for the prompt reply. Ray
  8. I have an ED80 that I want to 'convert' for solar viewing/photo use. It is my intention to use the Bader Film mounted in a ring to sit inside the dewshield. My question is. In order to avoid getting any pinholes in the film would it be in order to mount the film between two sheets of suitable glass, presumably with a small air gap? and would it need to be optically flat glass.
  9. Have you any form of voltage controller? These have large value capacitors in them that can take a while to discharge. If you have a moisture leakage path somewhere then this will give the feeling of persistence. IF the problem lies in the transformer then you need to get an earth leakage check done. (A PAT tester will do it.)
  10. The fact that you can 'feel' a bit of leccy would tend to indicate a possible earthing problem. Probably a slightly 'loose' connector. The most likely cause is damp. A little moisture will allow tracking. Ensure that wherever a cable enters a plug or socket that the gap has a little sealer around the cable. Take them indoors and give a bit of tlc and warmth before sealing.
  11. They have some of these in Kings Lynn shopping area. DO NOT look up at them, the led's are blindingly bright.
  12. Sounds as though you need the screws I used to make for my rings. M6 in brass with screw in nylon inserts. Only stick out 1mm and can be replaced if neccessary. P.M me if you want further details. cheers Ray
  13. Try here. They supply almost anything by the inch or foot. http://www.m-machine-metals.co.uk/ ray

    Try here for the tube you want. They sell by the foot or inch. http://www.m-machine-metals.co.uk/
  15. Where I live (March Cambs) most of the 'A' roads are unlit. A recently built dual carriageway, (to motorway standard), only has lights at the roundabouts. A new major road construction near Spalding also only has lights at the roundabouts. They are white and all of the full cut off type. Someone is at last thinking off the environment in all forms.
  16. If you want a dome without the curves then prhaps this one would do. Cymbeline Observatory
  17. Thanks all. sums up moer or less what I was thinking. Ray
  18. LIDL have an astro Planetarium foe sale at £49.99. Has anyone bought/used one? If so, is it worth my lady, who wants to learn where the stars are etc, getting one? http://www.lidl.co.uk/cps/rde/xchg/SID-BEA704FB-90BF1BD6/lidl_uk/hs.xsl/index_6893.htm Ray
  19. At the risk of getting flamed try this site. Most are free, some you have to buy. http://thepluginsite.com/resources/freeps.htm
  20. The power supply was actually built for ham use. It has soft start and remote at point of use voltage sensing. 12v at the sharp end often means 15/16v at source. The power supply wieghs about 60 lbs!. All I had to do was get a new xformer made. The cable will be about 50ft long and I will be using 4mm cable. I have the unit open at the mo so I'll take a pic and put it up later. ray
  21. If you intend to bury the cable when the ground becomes diggable again then get ready for it and run the cable through a suitable length of hosepipe. Very difficult to damage the cable and no probs when burying it. I ran a power cable (25A) from the board to my workshop, a distance of 134 ft and never had a problem. However when I have finished my obsy I shall be running a new cable from my power supply at 12v DC 30A (360 watts). the power unit is in my study. I'll put details up on my website as I get to each stage.
  22. I can reccomend JMR Section Benders Ltd. They will do a one off. www.jmrsectionbenders.co.uk
  23. If you decide on made to measure rings can I help? I roll them in steel with whatever plates you want on the bottom. Macmarch (Raysrings)
  24. I am in the process of building an obsy. Wanted to have a dome but the construction of curved surfaces!!!. Have a look at this one. It can be built in sections and bolted togather. Cymbeline Observatory ray
  25. Take a look on the UKAI site and all will be revealed.
