    Coronavirus transmission prevention device.

    Sarcasm? Where?. Intricate electronics takes patience, Caronavirus takes patients. Martin

    Coronavirus transmission prevention device.

    I gave the ex-wife a paper bag!. Could that be why she’s now my ex? Martin

    Coronavirus transmission prevention device.

    That is a great idea!. An audio amp in a back pack, a speaker round the neck and a microphone glued to the hand. When one raises said hand near to face, feedback squeel is produced... What happens if the person in front of me sneezes?. Presumably one would feel the moist deposits land on ones...

    Antique "Acoustic" amp needs attention ASAP

    That looks like a guitar head unit amp. Usually sit on the speakers. Similar to my old H&H set. Amp input is to add another amp (daisy chain) Or Amp input and Pre Amp out for effects loops. You can use these for a mixing desk too. What model is it?. I would imagine it would sell for over £100...

    Need help with Arduino Code for coil winder

    Thanks chaps, my laptops are XP, Windows 7 and Windows 10. It’s not a computer problem. It is my naive buying skills!. I read about FTDI ages ago. I had to d/l drivers for CH340 chips. But it seems that some Arduinos don’t have the bootloader installed. I have a working Nano which I’ll use to...

    DIY RC Filter replacement

    X2 caps are readily available on all sites or shops. As are the resistors. Your post code (zip) will indicate your local electroniics store. Martin

    DIY RC Filter replacement

    Absolutely fine. Still cheaper to seies two components as @Tha fios agaibh suggested. Martin

    Need help with Arduino Code for coil winder

    Ah hops, you will be just as short with me too soon. I now have 9 Arduinos and only 1 is windows detected. ALL for another thread soon. Martin

    DIY RC Filter replacement

    More than likely as fruit machines are more commercial than industrial 3 phase. X1s can be used but cost more. Martin

    KENWOOD KR-V7030

    You have plenty of inputs. Question is what do you want to go through the equalizer?. If you want all inputs through the EQ, you’ll need a mixer. Connect all hi-fi components to the mixer. Connect the mixer to the EQ and connect that to one of the amp inputs like CD etc. Martin

    building a noise activated sensor to record the noise and duration the noise is made

    Yay, shot gun check first!. I think you are over complicating this. Plenty of VOX and sound activated mini recorders available like personal dictation machines. You can’t autonamously record a barking dog without also recording the passing loud cars or thunder clap. Human intervention will be...

    ASK what voltage is really this power supply?

    Hi NVZN, It sure seems to be a variable supply factory set at 24V - 400mA. I would imagine it can be adjusted by board components or simply a potentiometer. The new adaptor will work just fine. The polarity and voltage are correct. The higher amperage rating is also fine. Two things could...

    They are time delay fuses. 1A @ 63V. Martin

    What do you look like?

    My top half resembles a blown/swollen cap. My bottom half resembles a transistor with it’s centre leg broken off. No algorithms required!. Martin

    Use for old scanner?

    Edit: It wasn’t ‘monitor’, it was scan mode. You enter a lower limit and higher limit. It then scans those frequencies and stops on a transmitting frequency while displaying that frequency. If you liked what you heard, you could then monitor that particular frequency while still scanning for...

    Use for old scanner?

    You should be able to use it as a crude frequency monitor/display. I am sure the Bearcat must have a Monitor button?. With mine I can monitor channels between two set/entered frequencies. It will display that frequency if present. I used mine with RC car tracks and RC flying fields to name just...

    isolating transformer and variac - what order?

    Ebay. I bought a box of 17 bulbs for £12. Yes, pricey, but still available.
