    SSD doesn't boot at first start

    Have you set the boot sequence correctly? Is the SSD 'bootable'? Does the PC do a reboot properly (via the reset button)?

    Vivo travel charger not charging

    Usually not worth repairing those things - without a schematic and test equipment etc there can be numerous reasons for failure that would take far too long to delve into.

    Vivo travel charger not charging

    It's not a resistor, it's an inductor, 1000μH going by the colour coding and the 'L1' designation on the PCB. Best search for a reason for its demise before just throwing another one in.......

    SSD doesn't boot at first start

    What PC? What OS? What BIOS?

    AC 18650 Replacement?

    Datasheets that I've seen show the device running at an 'average' of 1500mA. It's maximum dissipation is 10W. How hard it is driven is entirely down to the method of cooling employed but without that information we can't make any determination for current consumption at all. If the OP doesn't...

    AC 18650 Replacement?

    The LED may be driven in its constant current mode.

    Yamaha RX-V1070 front display not working

    Not on that very limited description. You could at least have included a picture or statement of what it actually is! Can you post some pictures and/or schematics of the various parts of circuitry? Looks like a VFD (vacuum fluorescent display) which require a high voltage supply applied to...

    F-31816

    Sounds like in-house markings to me. Are you sure of the symptoms to actually declare that device dud? What does it drive?

    Wanted: Electronics components

    Other than the major suppliers like Farnell and RS Components (and their prices aren't that ridiculous) I get parts from ESR Electronics (Cullercoats, Northumberland) where they have a good supply of standard parts, reasonable prices and fast delivery.

    Searching for the perfect lcd display

    I don't think you'll find one at all. Most small screens conform with the standard graphics formats or 1/4 parts thereof - the 320x240 being very common indeed (1/4 VGA). You'll be looking at a 5" or larger display before you get to 800x600 but the 16:9 ratio is another thing altogether. The...

    Mosfet gate voltage

    Voltage doubler/tripler etc require an alternating waveform to work but otherwise, yes, you can do it. But why would you want to use such a circuit if all you're required to reach is a 'lowly' couple of volts?

    You saw the OP's name - what do you think? :p

    Card Reader type

    Just go online and look for the channel/frequency you are scanning/using. The details will invariably indicate which coding system is in use for the signal you're receiving. If you get a PC-based receiver card system you'll invariably find software that decodes 'everything' on the fly...

    Wrapping Exposed USB Drives With Electrical Tape

    Clear heatshrink tubing is easy to apply and, if you slip a piece of paper with whatever printing on it under the tape before shrinking then you get a key with all the info you want and decent-enough protection - including physical strain relief. Still won't stop you inserting the key the...

    HP Printer doesn't work anymore

    Take the printhead out and check that the connections between the head and carriage are perfectly clean, undamaged etc and look for any breakages in the ribbon connector. There is a 'physical' fault here and it's either with the head or the ribbon OR the printhead really IS dud and will require...

    Electrical gauges

    If you remove any shunts (ammeters) then the meters all become 'volt' meters and can be 'equalised' in range by the addition of a suitable series resistor. Thereafter it's a simple matter to find a number of different varying voltages - these can be from an audio source (diode and capacitor off...

    For Sale: Vintage Silver Mica Molded Capacitors

    There are sites dedicated to the absolute restoration of radio's that MIGHT be interested in these parts. They aren't exactly common but, then again, nor are they in demand hence the incredulity at the requested price. Modern SM capacitors with 500V ratings are only $1 (or less in many cases)...
