    Maximum solar panel wattage for 200ah gel battery

    There is no such thing as 'too many'. Up to a point you will fully recharge the batteries at their stated maximum (even whilst drwaing power for the connected domestic equipment) and then have to 'dump' the excess power - usually into large water heaters. How quickly that happens depends on...

    Government disclosure of UFO info tonight

    Any slow than FTL and someone will have the wheels off their spacecraft. Bagsie the battery!

    Recommendation for re-winding transformer?

    Output transformer or mains supply? If mains, you can usually source a replacement equivalent (unless you're trying to do a restoration and want an identical replacment) but if it's an output transformer then have a go at rewinding it yourself!

    IC MK1841D3 Board from old power supply

    Hmmm.... the 'guidance' will likely turn into a full-on step-by-step process that I doubt many have the time to dedicate towards. We're always 'happy to help' but there are limitiations. In this particular case the data above shows the power supply and the 'signal' connections which will...

    Random digital potentiometer driving

    The R2R/LS595 version gives 128 distinct steps. Not sure what your requirement is.

    Random digital potentiometer driving

    Use a 74HC595 to drive the R2R ladder and clock it up/down through a NAND being driven by a slow pseudo random clock and a fast version (fast being the clock, slow being the 'stop' - both being 'random' makes for an effective result). You could even use another slow P-R clock on the 595's...

    Coronavirus transmission prevention device.

    I'm not supporting the claim the 89-year old made... just pointing out that it hasn't been disproven - yet. In much the same way that there's no absolute guarantees that 'something' won't see you off this mortal coil in the interim - although some would put such an event down to C-19 as being...

    TFT Screen problem (Toshiba TECRA 730CDT)

    Can you run any other software than the boot screen? Try finding a 'test card' software such as this: https://www.eizo.co.uk/accessories/software/monitor-test/ post your findings.

    Random digital potentiometer driving

    An R-2-R ladder used as the 'pot' and clock-driven by a psuedo-random gated clock signal would work.

    Building a 4 poles filter

    Why a pronounced 'dish' requirement? This isn't 'good' for any reason I can think of when designing filters.....

    Coronavirus transmission prevention device.

    It's not a 'mis-truth'.........yet. Just as so many conspiracy theories eventually become conspiracy fact you can't dismiss any statement so readily. Far too much evidence supporting the 'conspiracy theorists' is being revealed every day, not least Pfizers own document dump (which they wanted...

    Random digital potentiometer driving

    errr...... so, what's it to be? Digital or analog?

    Coronavirus transmission prevention device.

    Nothing worse than someone prepared to tell others how they should live their lives. Well, yes there is - it's arrogant people forcing others to take exprimental medical procedures against their will. That is above and beyond the pale. Unbelievable. Should I take a headache tablet to stop...

    Coronavirus transmission prevention device.

    Covid survival rate for all age groups exceed 99% and increase to 99.993% as you go down the ages. This is not and never was a 'pandemic' except in the minds of those that were convinced it was. I personally know of more people dead from the vaccine than dead from the virus. Fact.

    Microwave sparking from side panel

    Keep upload pics to under 300kb in size. Most likely the magnetron is dud now - I hope you're aware of the thousands of volts used in a microwave??? And the filter capacitor that can hold a charge after the power has been removed?

    TFT Screen problem (Toshiba TECRA 730CDT)

    Has the device been dropped at any time or dismantled/rebuilt? It looks as if the LCD filter may be out of place - touching at the left side, gradually increasing in separation as you approach the right hand side. If you HAVE dismantled it did you go as far as separating the individual layers...

    Cannot find this specific resistor, help!

    If the resistor keeps blowing then you have a fault elsewhere in the ciruit and the resistor is preventing even more damage occurring by doing you a favour and burning out! Resistors are cheap!

    Pot identification and alternative

    Remove the pot from the board and dismantle it - there are only a couple of 'tabs' holding the thing together and you might even be able to see the cause of the problem and fix it. I've done a similar fix to a pot in the past.
