    Triac help

    Adam, Not so fast! If you look at the datasheet you see that you need a few more parts to make it work. First a series resistor for the input (or you blow the led inside). And also a snubber circuit to help the triac get the correct gate current and such you can see an example of this on page 4.

    Kinda stupid question

    Hi Edude, Yes on the secondary side of your PC PSU (5Volt or 12Volt) you can attach a LED if you also add a series resistor for it.

    voltage divider for AC

    Hi Ian, What kind of SCR dimmer do you recommend for such device? The output waveform from the once I have seen does not work any good as input for a transformer. Usually the transformer gets overheated and destroyed since they are an inductive load and thus do not like the pulseshape...

    Schematics Variable current 12v 60A to 0A

    Dazza, We need to know the output range from the sensor where it is supposed to work (0 to 25psi) or something like that. You have indicated 2.43 to 3.62V, was this the final decision or are there still changes to be done regarding magnets and moving ranges and so on. Until we

    Dazza, You have to find a small enough relay to rob the coil from if you really want to have adjustable strength. There are some very small relays out there, the smallest SMD type I don

    Pulsing Third Brake Light

    Stuee, Sorry I did not realize that it was one of the projects on this site. For SCR1 you can use 2N5062, 2N5063 or 2N5064. The diodes are any standard 3A.

    Help needed building a room light with integrated roulette circuit

    Hi Benn, Welcome to this forum. If you have the roulette circuit you can use half of the LED outputs (5 of the 10) to drive a triac for each of the lamps. Put a switch on each wire to enable individual on/off. Yes the transformer can be used but the electronics must have DC so a rectifier and a...
