    Mon petite . . .Belle . . . . Ohhhhhhh . . . the ADDED cost ( or profit gouging ? ) of making dedicated products for minimal marketing. That’s being just as easy accomplished, as building the simple circuitry I place for you below, more like $5 of parts instead of $200. You just double...

    Brake light flasher (555 - based) circuit works on breadboard, but not PCB

    Sir domiflichi . . . . . In a proof re-read I see that I omitted poking in additional thoughts of using a DVM in low voltage DC mode. You set up the breadboard model and initially monitor 555 pin 4 for its initial voltage just after powering up the stage and then after its time out and...

    Help Identify this chip

    What I really think that what you may have found yourself there, is a MOSFET driver chip . Does it only have one MOSFET tied into it or are there being two, tied into it? But there are not a lot of them that are only using eight pins, but that may simplify the search. Check out the Linear...

    Tesla Coil Under load

    Sir pidja105 . . . . . That should be QUITE a load, as each neon fires around 60-75 volt threshold and according to how many you had in series. A 4 ft flourescent tube would have been less of a load . Plus that level of input should be quite hard on the electrodes. If you have a scope you...
