Re: Problem with AC/DC adaptors - a question for electricians

I don't have a prototype board yet and had to hold the wires and bulb in my left hand and the phone in my right ;)

Re: Problem with AC/DC adaptors - a question for electricians

It sounds like you shorted the batteries through the Amp scale of the multimeter. Normally this would have blown the fuse that all multimeters have in their Amp scale to protect their circuitry from someone connecting a voltage source across the Amp terminals. Apparently, AA cells can't put out eno...

I had a Lego Technics set that had a motor in it. You could build a crane and, by changing the polarity, pull the rope up or down.

Re: Problem with AC/DC adaptors - a question for electricians

With no load except a voltmeter, AC/DC adapters with unregulated outputs will have much higher output voltages than their specified output voltage. The specified output voltage is measured at the specified output current. Load the 12 Volt output (with a 100 ohm 1 Watt resistor for instance) and you...

Problem with AC/DC adaptors - a question for electricians

I own two 30-year old AC/DC adaptors. Specifications: Input: 220V, 50/60HZ AC Output: 1.5-3-4.5-6-7.5-9-12V DC Current: 500mA, 9W The wall socket has a current of 230V. I recently measured their parameters with a meter and found that the output voltage is almost 10V higher on each range, e.g. instea...

lol, I'm so ashamed! How many of those were mine?

Let's share without going into who wrote more: 1/3.

In my case: 237/(5+0.5) = almost 50 (less than 50 more than 20).
237(5+me)-172(3)=65/2,5(2+me)=26 (circa about)

I suppose the + means a smaller share in the number of posts.

He has Asperger's syndrome and because of this he can behave strangely and incomprehensibly.

Edit. But I think his posts should be read by a lawyer or PR expert before posting. For his own good.
