    Salvaged components

    I love stripping boards down and when I find something I haven't seen before or whatever I check the data sheet if I can find it. As I am learning all be it slowly I like trying to work out why things are where they are and understand their purpose in the circuit. I find it very interesting and...

    Multi meter question?

    I ended up getting a fluke 177. I'll let you know how I go with it over the next week or so. I've decided too. I'm going to try and fix the Extech so long as it doesn't cost me any more £££. I think it'll be a challenge but I was going to strip it for fun so nowt to lose. I'll let you know how I...

    Interpupillary Distance Adjustment on a Microscope Impossible?

    If you work in a lab,you get an optical microscope composite video adaptor! If not,you get the council version.......A PATCH! :confused:

    Multi meter question?

    I doubt I'll ever get to anything above 240v UK mains. If I do I'll probably need a few feet blast area and something with more safety than the best of Flukes has to offer! I've been messing about and the cheapo Hyelec is best on DC but is all over the place with caps,the Craptech is OK with...

    Resistor across LED

    I haven't got even the mildest of clues what you guys are talking about but I learned something too! I just don't know how long it will be before I can make anything that even nearly sounds sensible to me out of it...but I'm on it! I'll give you a shout when I've got it :D

    Multi meter question?

    Yes I've seen a couple of reviews (videos) of the ANENG and they are impressive for the price. I did think about one and may still get one. Out of the two meters I have now the £30-40 Hyelec copy of something or other is the one I trust the most. I want 1 meter I can trust as much as you can...

    Multi meter question?

    Funnily enough the other meter I have i paid £30-£40 for a couple years ago works fine....I think! :confused: The only thing I have to compare it to is my bench PSU. They match almost exact when compared at different volts so I tend to think they are correct unless they are out by exactly the...

    Multi meter question?

    The continuity has now stopped working on the Excrement Tech now too! Pile of chit! Gonna treat myself to a new meter this weekend then take the Excrement Tech apart and strip it! Few bucks down the swany but you live and learn. Wish I new enough to try and fix it just for fun and practice.

    Li-ion charging question.

    Its great there's a place where the important information you need is offered freely. This is a great forum!

    Li-ion charging question.

    I did read that on the data sheet and firstly brought them up to 3v then 3.2v very slowly @ .25A and then left them overnight. I then started the charge again at 4.2v @ 1.7A and I stopped the charge @ 200mA and left them for 2 days. I then charged again @ 4.2v and stopped them @ 130mA,I'll check...

    Li-ion charging question.

    I love having a good look around the stuff before I strip it. Seeing how everything goes together and as I'm learning (all be it slowly) I try to work out why everything is joined up the way it is. I like googling the parts and reading the data sheet and it helps me understand why things are...

    Li-ion charging question.

    I read the link you posted,good info for a complete beginner like me. Thanks! I use my bench power supply to charge them so I'll err on the side of caution and stop them around 150mA. I got the cells from an old think pad i stripped,they lay dead for a long time with no charge at all. I'll...

    Li-ion charging question.

    Cool,thank you. I stopped the charge at 200mA as didn't know. I will read the link then put them on charge again. I'm taking my first TV apart just now so will get to the batteries soon.

    Li-ion charging question.

    I have retrieved 6 Li-ion cells from a think pad I took apart. I've searched them on google and found the same ones Sanyo cells. I've split them into single cells. I've charged them @4.2v 1.7A like the data sheet says. My question is....is it safe to let the A fall away to 0.000A? I've been...

    Multi meter question?

    When I short the leads it returns to zero. I put a new battery in soon as I got it. There's a club not too far from me I've just found out about that has all the test stuff. Its like a hacker club. I'm sure they will have a decent meter I can use to find which one of mine is correct. I NEED A...

    Multi meter question?

    I have a Hyelec MS89 multi meter I bought a while back,just a Chinese cheaply! 30 or 40 quid or there abouts. I've used it for odd jobs for a couple of years. I got a Extech Ex505 multi meter and a Tenma 30V 5A PSU recently when I decided to get into hobby electronics. The Extech i got from...

    Charging my power chair from a bench PSU?

    I was just thinking of doing it once or twice,I wouldn't want anything permanent in place. What your thinking of as a power chair is correct,two 12v lead acids powering it. Is it in series or parallel so it gets 24v? They guys on the other forum convert their chairs from lead to lithium. The...

    Charging my power chair from a bench PSU?

    I have wondered for a while now about doing this. Just because. I know my proper chair charger does this fine but I'd like to watch it happening. I'd like to see the process happening with one or both my meters hooked up measuring it and also watching it on the displays on my bench PSU. I'm...
