    Alloy wheel cleaner

    Wonder Wheels and the like are great until you realise that every time you use them, they make the next clean harder and are gradually killing your wheels. They're acid. Acid and lacquer don't play well. If your wheels are in reasonable condition I recommend doing a very thorough clean once...

    SLR camera batteries

    The first "Nikon" battery I bought turned out to be a fake so if you go that route buy somewhere reputable and then check very carefully (you may be able to find details of the mass of an original as this is one way the fakes often differ). I've had luck with some Neewer replacements for my...

    Diagnosing cause of boiler not diring for heating - programmer?

    Thanks again for all the help everyone - really appreciated. I found that the motorised valve on CH was making a pulsing/buzzing sound when trying to open. A tap on the valve seemed to get the valve open and the boiler would kick in (sometimes taking a few gos). Problem was still too...

    Thanks Ian - will report back when I know.

    HDD's on TV's question

    Plex support on the TVs is as a player as Lucid says. Plex is also a media server but you'd have to have a central media server to which the media players can connect. I can't think of a simple solution to what you're trying to do at the moment. If you wanted to investigate something, you...

    Diagnosing cause of boiler not diring for heating - programmer?

    Hey - thanks very much. Yes - that makes sense. Will give it a try when the problem next occurs.

    Diagnosing cause of boiler not diring for heating - programmer?

    Thank-you for the suggestion. I believe it's open vented (the hot water is a pressurised Megaflo), but there's a header tank in loft. There are two motorised valves, but I'm not knowledgeable enough about how the CH is piped to know which is which (any tips for identification - follow the...

    Diagnosing cause of boiler not diring for heating - programmer?

    Hi, Potterton boiler Potterton EP2002 programmer Honeywell room stat Stat valves on rads All on an install which has been working and untouched for many years. I'm after a bit of help to narrow down a fault. Our boiler is not firing up all the time even when programmer is on and hall based...

    Resistor identification help.

    Thank you both for your further thoughts on this. Yes, I had checked the optocoupler on the diode setting of the multimeter. I fitted the resistors today. 3W and substantially more beefy than the originals. I decided to try it before replacing the optocoupler (on the basis that I could...

    Resistor identification help.

    Good call - I "think" the diode at least is dried as I have resistance in both directions :-). So I'll order one of these as well.

    Resistor identification help.

    Good guess. The existing ones are 11mm. I'd ordered some 3W ones, but will try to find some 1 and 2W ones in case space proves to be an issue. Thanks very much.

    Resistor identification help.

    Taking another tack, I found these pictures of new boards. Still not completely clear since photo colours are not always accurate, but looks like 12kohms (5 or 10% tolerance)???

    Resistor identification help.

    It's a Chamberlain Liftmaster. Still confused by the resistors because looking closely it looks like R2 could possibly be Brown/Yellow/Orange/Grey (although 0.05% tolerance on this size of resistor seems very unusual judging by what's for sale). All the colours have faded and are fragile. R2...

    Resistor identification help.

    Joints on the board all look good. I was just going by appearance (there are soot marks up the board under that penny where the resistors seem to have been smoking). U1 is apparently an optocoupler I started looking at this thinking I'd find a dead relay, but they "look" OK (as in not heavily...

    Resistor identification help.

    Hi, Can anyone help me check my identification of these resistors? They're on a garage opener. I'm hoping to try replacing them to see if there's a simple/cheap fix. If not, it'll be at least a new board and possibly a new opener as I don't know if these were the root cause. I think they...
