    Universal Remote Codes for Sharp TV

    That box of 'universal' remotes won't work if older than the TV :( I had success with a 'learning' type of remotes, but you need to borrow one that works to copy the codes. Awkward.

    Inject sound to a phone landline (electric boogaloo)

    To inject audio to a plain telco line which is 2 wire lines, not four; you need a plain audio output transformer; like 8 Ohm to 1K Ohm. ( Like RadioShack 273-1380 ) Connect the secondary 8 Ohm winding in series to only ONE of the telco wires pair. Inject audio to the 1K Ohm primary...

    Universal Remote Codes for Sharp TV

    Every brand of 'Universal remote' will have a different code for a given TV. A 'Sharp model32xyz' TV will have 'xxxxx' code if the universal remote is RCA. Will have a 'yyyyy' code if the universal remote is Magnavox. Will have a 'zzzzz' code if the Universal remote is... And if the TV was...

    Samsung smarty fridge... no cooling

    And that board is an inverter that you do not know if it is bad and want to replace ? I would discard that sheeet circuit board and make the fridge work without crappy whatever-it-does 'smarty' electronics prone to fail at the first utility spike, using just a thermostat instead. I do not need...

    Electrolux fridge three way

    Gas utility companies offer free pilot lighting for security reasons and courtesy. Try them first. Do not know what a belt has to do here. Tell us the model of the unit. From the web: 5 If the refrigerator fails to work on gas, check that: a) the LPG cylinder is not empty b) all LP gas...

    Making a LED bulb to produce a faint light ?

    Faint illumination = exactly what I want it to be, calculated to work on 120VAC for current and impedance for the number of LEDs I want and tested and in operation for 13 years now for days and nights with no failures and not destroying themselves. No rethinking. Made 3 types I installed in...

    Making a LED bulb to produce a faint light ?

    Hi. A very high resistor value or a very low capacitance across the wall switch contacts should produce a faint illumination, right ? Like 1.2 MOhm on 120VAC would conduct 0.1 mA. Will try and post results.:rolleyes:

    LED bulb glows even after switched off - Can capacitor help?

    Actually I like the faint light presence when off. The capacitance between AC lines in proximity is what causes it, microamperes of induction. A resistor of high value or a capacitor of high voltage AC at low value should shunt the behavior. Try the minimal that works and come back with...

    Micro parts

    Yes, use your LEDs to illuminate your plastic parts. Put your battery, bluetooth, together on a pcboard and control with a application after you source the tricky micro parts on the net.

    Connecting copper and iron wires

    Just join them on a terminal strip, terminal block, crimping, riveting, or solder as both accept soldering fine. 1 Ampere will not give trouble. Cover the splice with silicone or shrink tube, or vulcanizing rubber tape compound. These mounted inside a plastic electrical box will be great :

    I want to make a speed limiter for my motorcycle

    I see a couple of things here: A motorcycle speed limiter is NOT an engine rpm limiter and they have been used with no distinction here, at least in the responses I glanced... A speed limiter takes a governor driven from a wheel. A rpm limiter takes a governor taken from a crankshaft...

    I want to make a speed limiter for my motorcycle

    My old cars with modern transmissions use now a circuit I made with a LM2907 chips to engage the TCC at a certain driveshaft speed. Such chip can be used for your task by shutting down the ignition or control something ...

    Little solar powered battery and led.

    Welcome. 'Little' means nothing; 10 to 15W may not be 'little' for many. 4 lithium cell if in series, can be around 12V to 16V depending on chemistry and the charge voltage should be not more than 14 / 16.8V for the group. BMS board should be used then, and the solar panel should be of a...
