    amp and Volt meter

    awesome. wingnut. so using that I can use a quick scale to calculate the % of 5volt thus giving me the right voltage for 40 right? so if for example the voltage on the pin is at 75% of 5volt then it would also be at 75% of 40volts right? also would I have to modify this circuit and if so how...

    amp and Volt meter

    doh just realised the stupid heading... its supposed to be amp and volt meter anyway the best I have seen is going to 20v using something like this using 50k as R1 and 4k3 as R2 this apparently measures up to 12volt how can I get that to 30 or 40v just to be safe?

    Multi I/O timer circuit advice

    have fun with that. without a deposit no TRUE professional would be willing to even look at this, unless you sign a very lengthy contract that may include a nice little clause like "while you wil retain the copyright of this product we will be entitled up to 90% of profits from sale"... and if...

    USB to Webcam connections

    give us details on make and model might be useful too. most importantly is the pic of the circuit board and the wire that is broken if you think the wire is broken inside the usb cable the EASIEST way to replace it without too much hassle is cut the chord about 3/4 of the way to the USB...

    Need some basic help re: strobes & batteries

    Need some basic help re: strobes & batteries

    why not grab a 6v sla battery instead? this is both rechargeable and is the exact voltage requirement for your strobes.

    Local language speaker

    no a computer is a few things, smartphones now have apps to do this. there are little translation computers that you swap out the memory card for each language and it says the phrase for you. these are no bigger than a smartphone and smartphones have dual core processors now. don't think a...

    complete noob with electronics! help with basic motor control, please?

    you are new so HI there and welcome 1) connecting to multiple components IS as easy as connecting wires to the batteries, think of your home entertainment unit it has a dvd and a t.v. both running from 1 outlet, just using 2 different wires. 2) as stated above you can just split the wires...

    Heating Element?

    I can see no other purpose for this at this time except what bobk has mentioned, however I must point out a few things. even though I am dead against the taking of drugs, there are countries where it is allowed so this could be for a legitimate reason in their country. although the MAIN use...

    3d imaging

    I wonder if placing 3 or 4 of these evenly around the object would work to speed up the process. the issue then is will the scanners on the opposite side be part of the scan? I guess with cad you could remove them if necessary anyway
