    Noisemaker Revenge Machine

    It might work but 1A is on the small side. 3A or more would be much better. Your original adaptor will be fine with a smart plug. Regarding taking to an electronics shop, no need. Simply cut off adaptor connector and motor connector, then connect to new PWM board with screw terminals. Each...

    Noisemaker Revenge Machine

    With my lack of knowledge with microcontrollers, I can't see a way to circumvent it and still use the board you have. IMHO, and simpler for you, I think you'd be better off with a seperate PWM controller. These are cheap as chips from £2 upwards. Here is one for example. And another here. And...

    Don’t be silly, we do it because we enjoy it. AND because some of us have nothing better to do!:) Martin

    I’ll have a look at the data sheet when I get home. Nice clear photos. Martin

    Yeah, I noticed that too. The OP wants to circumvent the board if possible. So I didn’t bother mentioning it as it is working. Martin

    Fluctuating suggests PWM. The IC numbers will be required to see if there is a work around. But you can buy very cheap motor controllers that you can adjust for that very special night!. Martin

    No. Put the probes on the motor connections while powered. It may already be PWM. I can only read one IC. That is a 5V regulator (U1). Can you read Q1, Q2, U2, U3 and U4. Martin

    Do you have a multimeter? Martin

    That is the funniest thing I’ve seen!. Kanger exercises?, sounds scary. Measure the voltage to the motors, it may be 12V. In which case you could run it direct from the adaptor and a timer/smart switch. I wouldn’t run those cheap motors for too long though, keep an eye on temperature. You could...

    That looks like an interesting torture device. A twin turbo vibrator. It’s probably a micro controller with built in (programmed) speeds with a tactile switch. Can you take close up photos of both sides of the PCB. Do the motors have any writing on? Like voltage?. Martin

    Please Help Identify This Electronic Symbol

    331 would suggest a 330μH inductor. Not polarised but may have a marking for current direction. Martin

    Quartz Halogen Lights - New Transformer - Lights now dim

    It looks like both red (HV) 120VAC wires from the new transformer should go to black and white connections on the control box. The two white (LV) 12VAC go the the bulbs. Martin

    I feel like a silly school boy!. It is 820K. Martin

    RGB LEDs

    Well, I have measured several scenarios and came to a happy compromise. I’ve added an extra power source to the GREEN LEDs via diodes and via the car lights auto dimming circuit. We now have brighter LEDs in daylight which dim when the car lights are turned on. And all are dimmer with the...

    Well done. Scratch that on your bed post and search for something else to repair. Job satisfaction guaranteed. Martin

    RGB LEDs

    It’s clearly off without a power source and once connected, it’s clearly on. Later I will try my bench supplies as I’ve been using my RS powered breadboard. Although I was keeping a close eye on voltage, a second test won’t hurt. Martin

    RGB LEDs

    Hi John, I’ll do more measurements tonight. It’s my math I doubt. I get light headed when moving the decimal point!. I will try less resistance too, but 820K was too bright in the car at night. Very strange. Martin

    Thanks Bertus I just changed to the old style on my phone and don’t see any changes. I’ll try later on the laptop. Purely out of curiosity!. Martin

    How do I know whether I have the old vs new style? I presume being web based, I am seeing the new style. It’s been a while since admin changed and I can’t remember. Martin

    Solar lead acid battery housing

    As a child I was always told NOT to sit on concrete floor for erm... medical reasons (piles). Now I’m reading myths and old wives tales. Some are hilarious:). Martin
