    Driving a HDD motor

    The author refers to this circuit as “very crude” which probably means that he is well aware of the fact that it can be significantly improved!

    Slow power up effect

    Have you tried to use both a capacitor in parallel and a resistor in series with the meter?

    Nest Box Camera Help

    Are you sure about having it wireless? It might run for a few hours on a PP3 but with half a dozen IR LED’s it will only last for 5 minutes or so.

    turn wind into an electrostatic generator?

    I am sure you know I was just kidding Steven! ;D  However you can get your hair to stand up if you are charged with static (HV) though! ;)

    110v supply

    The sensible thing to do (if possible) is to remove a number of turns on the 130V winding to get an 110V output.

    transmission lines

    OK, and at which frequency does the 50 and the 75Ohm wire put up zero Ohms impedance?

    NAD schematics urgently needed

    Perhaps for the same reason as all the other useful stuff was deleted; its copyrighted material!

    NEC monitor help!

    Oh yeah, I forgot to update this one! Sorry! I found that the inverter transformers (both of them) had open circuit (secondary)! I scavenged a couple of working inverters in a dumpster at work and the thing is now working perfectly. I can’t figure out why both transformers “died” but as things...

    EMC Question

    Subs uses much lower (VLF band) frequencies at 3-30 kHz to communicate digitally sometimes even ELF!

    transmission lines

    Hi AG, At which frequency is it a short (zero ohms)? How many meters (or feet) is 50/75Ohms? Are you talking resistance or impedance here and what frequency?

    Stun Gun from Camera Flash

    ;D Stun guns are supposed to “stun”, this camera circuit is way too lame to do any harm so don’t worry!

    electronics all in one site

    One post would be enough, no need to litter the site!  >:(

    Electronics knowledge Magazine online www.circuitseed.com

    No pop-ups if you have a proper browser! However the site has very little to offer; only “Prjects” links to already well known sites! >:(

    TENS voltage stabilisation.

    Hi John, Welcome to our forum. To stabilize the voltage we need to see the circuit schematic.

    turn wind into an electrostatic generator?

    Hi Steven, Isn’t all bicycles upside down, down under?  ;D

    Inverter Circuit 12V DC to 230VAC Sine Wave

    These bulbs are usually something like 10 – 20 W, this is not always marked on  unfortunately.

    Linearization techniques

    Hi vdd, If you can “open up” the proxi sw you will find a Schmitt trigger in the circuit, this is what makes the output a switch. The circuit before the Schmitt trigger is an analog inductive sensor.

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Hi Steven, The 2A 250V you’ve got there must be the maximum rating for the socket not the bulb I believe.

    Cool Component Search Engine: Crosses, Data Sheets, RoHS

    Hi John, Yes, this must be a brand new database in which they haven’t put any data yet! I also tried many part# and they all came up empty! >:(
