    CircuitMaker 2000: Any users here?

    Hi Terry, Maybe it's time to upgrade to the FREE LTspice software. It looks very similar so wont have a big learning curve. You'll also get a lot of help here too. Plus in the resource section of this site, it's got lots of help tutorials. Just a thought.. Martin

    Starting DC motor by squeezing handle

    Sir Hop Poppins comes to mind...:p Or should that be Inspector Hop.. And then the fan stops and a camera pops out for the SELFIE!! Martin

    Trouble understanding circuitry for guitar pedal project

    4. What's a ground line? (and counting):D You should set your board out something like the pic below. Then you have your positive and negative rails. If your components are close enough, bend the leads and solder them directly. No need for extra wiring. Martin

    Creating an LED array in series circuit using PCB

    Not if you don't need to. If the LEDs are close enough to bend the leads and solder them directly. Also if you are planning on running several series arrays, put a resistor on each of them.. Martin

    Reverse Polarity Damage... I think???

    That's good news.. Now you have to buy another pedal for your spare adaptor!:) Martin

    Starting DC motor by squeezing handle

    I hear ya Hop, but it does keep the grey matter ticking I also think you nailed it!! Air switch.. Hospitals use them all the time too rather than leaving the inferm with wires.. Now the trick is not turning on in the central points. But as you said, the OP hasn't responded yet.. Martin

    Starting DC motor by squeezing handle

    Yes Hop. The picture I posted was from a 'special needs' web site without further info on the switch. Just a hefty price! But as far as I can make out, they are all just diaphram pressure switches like boiler (furnace) switches. Martin

    Faulty tv power

    Oh dear Boo.....You didn't read my post properly...BTW, what electrician in the shop? I will do as @davenn did... IT IS NOT A 15A FUSE. It is a 3.15A fuse..Let me spell it.... Three point fifteen amp. (point being a .) Replace with a 3.15Amp and cut R4 out. R4 is causing a direct short. Once it...

    Looking for insight on building an AFAD trailer

    Hi Crazy Bry.. Good idea to rent it to the boss!! Are those switch thingy's on the motor lines limit switches? The drawings look ok. But it seems like everything will happen at once? Getting the lights to flash for 5 seconds and then on constant seems to be a problem. That's why I mentioned a...

    Push button start-stop computer psu without motherboard

    Hi Bobsone, Does the psu have a purple wire? That would have powered a constant 5v USB port as long as the main plug is plugged in. So the latching circuit would work with that. Failing that, most people switch the green wire. But obviously that would need to be an on/off switch. You may be able...

    Looking for insight on building an AFAD trailer

    Is this why they call you Crazy Bry? That's a nice project.. Can you not find a secondhand unit that needs restoration of sorts? Or possibly buy a main board and remote as spare parts from HERE. Some nice information and specs HERE. As much as I hate to say it, this is a job for a...

    Starting DC motor by squeezing handle

    Ok, I admit I am completely confused here...An Arduino and a fan inside a "broom" handle diameter tube? Anyway, I am with @hevans1944 with air.. Adjusting it to turn on and off is easy. The bit in between will take some playing with.. I found a "squeeze" switch. It will basically force air down...

    Replace 680uf capacitor on a Vizio VW 42L LCD w/ a 1000uf capacitor

    Are you assuming bad caps on the inverter board? These TV's, apart from the 24v from the power supply also have a 5v 'turn on' from the main board. Bad caps on the main board can point to a dead inverter too.. Just my 2 cents..:) Martin
