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

    I've been looking to pick one of these up but the prices are rediculous! Why are they so expensive when you can buy all the parts 1000s at a time for pennies? Usually eBay and the likes are flooded with this type of thing for next to nothing :confused:

    Help selecting my 1st DSO please.

    That's it sorted then. The Hantek it is. Thanks for all the help and comments.

    What is your troubleshooting sequence?

    All great reading and helpful info. Invaluable to someone just starting out. These things will stick in my head for years to come. I'll never get to the level of most guys here but will still fix my own stuff when I need to.

    Help selecting my 1st DSO please.

    Cool. I think I'll get the hantek one. I like the look of it and no one has said "NO NO DON'T BUY THAT IT'S RUBISH"!! I have a very basic Tenma analogue scope just now and I've enjoyed learning on it so digital is next for me. :cool:

    Help selecting my 1st DSO please.

    I better grab one quick! I bet once everyone sees this they'll be sold out? :confused:

    Help selecting my 1st DSO please.

    I've seen a hantek one, 5102b 100mhz £200 Looks decent enough to me but I've learned it's better to ask before I buy. o_O To be honest I'll prob have a go at a few different things but I won't get into anything seriously. It will just be simple stuff. Nothing where I need exact scientific...

    RF sensor to detect cat

    I have one of those. It farts quite a lot though and I do have to feed and walk it twice a day. It's called Buster. It doesnt need batteries and i havent charged it since i got it a year ago! It does have a hole in the back though.......so I may try and plug it into the wall socket later and...

    Help selecting my 1st DSO please.

    I need some help selecting my first DSO. I only intend to use it for nothing more than hobby stuff and I am still very much new to electronics. I got a cheap analogue Tenma scope a couple months ago and had great fun learning how to use it. I probably still haven't learned most of what it can do...

    HELP!!! I have a fault -- Read me FIRST

    Awe man! You know all that clever electronics stuff and you can't even mind read? I'll give you a crash course Dave :cool:

    Transformer/Rectifier repair

    Submersible pumps! That brought an unexpected smile! Before having to quit working due to multiple sclerosis I worked in a roads and sewers gang. Mostly deep stuff so in amongst small water tables and stuff. The laughs I have had getting guys to prime a 4 stroke water pump while it's running...

    300 V DC Power Supply

    What sort of things would you use 300V for in hobby stuff or is that amount of V for other things?

    Nope! I see you. Hmmmm. :confused:

    help about this diode

    Yearly good info for beginners! These things stick for me somehow. I will remember this. Thanks for the knowledge.

    Difference? Regular resistor and a current limiting resistor?

    I wondered about that too but forgot to ask at the time so thanks from me too!

    Determining LED values

    Cool thanks Steve. I'd got as far as you need the resistor in line as most Dc V PSUs are even a tiny bit unstable (a little Ac V too) and even a small change in voltage can cause a huge change in the current (proportional to a LEDs) so the resistor keeps the volts steady and so more steady...

    Determining LED values

    Thanks for that. Easy to study and remember or check back.

    Determining LED values

    Sorry for sounding thick but why the current and not volts? I've thought about it and 0 volts won't create any current and 0 current won't allow even a single mV through. Don't you need both? I'm not questioning your answer,I know you'll be correct. I want to learn so could you explain that...

    Determining LED values

    It's the diode setting you need. -->|- kinda like that. The guys here will have the proper diode symbol. Like I say I'm still learning too so we will both learn when someone gives us the correct answer. :)

    Determining LED values

    You can get the forward voltage with most multimeters but the current "rating" you need the data sheet. You could work the rating out yourself with a power supply and a few resistors but it would cost you your led when you found out the "max" current the LED would accept. I think....I'm new so...
