    Mobility scooter

    Eventually!! Something I know a little about! :) If you want more speed you need more Volts...volts=speed. Most scooters run on 24v and the controller is good for 60-80 Amps....120 Amps is about as big as standard controllers go. Anything more needs other controllers which are readily...

    Battery charger questions

    Another answer for the Q2. Question. The chargers work on a simple BMS module detecting how much the battery is pulling from the charger. It just cuts off as the charging A gets near zero whether it's 10ah or 100ah.

    Battery charger questions

    One of the things with wheelchair batteries is say someone who uses their 4mph chair for dodging around a flat smooth care home with vinyl floors all day may charge up overnight and still be full at the end of the day so "think" their batteries are fine. Stick those same batteries in my 6mph...

    25V vs 35V capacitor?

    Thanks for the help. That's why I like reading these posts...i pick bits and pieces up along the way that I would normally never be aware of. It's cool too having people there who can confirm or correct the stuff I think I've learned. As with almost everything I'm learning just now a question...

    25V vs 35V capacitor?

    Thanks for the correction Harald. That's what I ment but I said it back to front. I knew it would be ok but said what I wasn't thinking. :confused: It's a max rating right so like you corrected half would have not worked. Are you able to go over this rating any or is it fatal to the cap if the...

    25V vs 35V capacitor?

    As far as I can see they are the same spec apart from the ripple current. The one you want to use is half of the one the manufacturer suggests so should be better. So long as the one you use is the same or a bit higher max charging V it'll be fine. That's what I think anyway. What's the worst...

    Building power supply help

    That's what I was thinking. You'll get a wall wart for a few quid. 9V is very common so will be easy to come by.

    300 V DC Power Supply

    My 30v 5A bench supply is more than plenty for me. I have a buck/boost module too that does 35v 6A but that lives in my desk drawer mostly. I was sent the module as a mistake when I ordered a £3 Capacitor mixed pack so I scored there! :cool: I've only used the buck/boost for 2 mins to check it...

    300 V DC Power Supply

    Holy €¥@£ neeb!!! Will 300v few Amp supply not need tied down good to the bench? That's a fair old jolt is it not?

    Are older computer components worth anything?

    It's not worth anything buddy......in fact I'd be doing you a favour taking it off your hands. Just post it all to me. :) I am kidding,of course! I don't know if it's worth anything or not but I am sure someone will be along soon who can tell you it's value. Hope you've found some treasure!

    Where to find scrap electronics?

    I love watching the restoration videos on YouTube. Like you say there's something about watching the older stuff come back to life. I can imagine how it feels to actually do it. I don't know enough yet for that but aim to one day. I wish everything wasn't getting microscopic and still able to be...

    Where to find scrap electronics?

    More silly rules! Someone working in a charity shop who prob knows even less than me about electronics can say to k_e or someone similarly knowledgable he can't have an electrical appliance because it will be a danger to him because it does or does not have a sticker on it saying so. They...

    Which other transistors can I use

    Ah cool. I have never heard of a VU meter before.

    Do I need a new capacitor?

    It's amazing the stuff you learn just reading other people's posts. Stuff you would otherwise not come across. I love reading through the posts.

    Commodore 64 Murder Mystery - The power supply

    So the "dumb" so and so who fudged up the PSUs ended up with......a big pay rise...a promotion....a pat on the back and is now 30 years retired to his own island just off the sunny end of Jamaica! :):)

    Where to find scrap electronics?

    Freecycle is awesome! I've had a few things there too. A lady even sent me a box full of circuit boards. I have found that a great way of learning some stuff too.o I google stuff for the data sheet as I strip the boards and actually seeing stuff on the board is better than reading or seeing...

    Where to find scrap electronics?

    You need to move to the UK buddy. At our recycling centre the guy was sound for me to take a couple things to fix/strip for parts. I'm sure ours is supposed to be "no scavenging" too. Maybe ask at the centre,look for someone who's cool. It'll be the same as most things in life,it's your luck if...

    Hello from the great white North.

    Awesome! Just make sure you don't try to multimeter the kids or wrap a stinky nappy around your PSU and you'll be fine. Electronics will be great to share with the "new" kids once they get older. It's a bugger that,when someone gets you a couple of new kids for your birthday or passing your...

    Why the crazy price for a decade resistor/resistance box?

    HOLY SMOKES!! No wonder everything gets subbed out to China! I'll keep an eye out for a decent 2nd hand one :) Dogs just farted too,,,,,he's howling! :eek:
