Hello. I'm trying to run a 24v D/C gear motor with the ability to control RPM between 20 - 35. Continuous operation, 9 hours per day. 50 inch oz. of torque. Looking at the Molon C15, or other type

Yup. It's a Law. As far as I know, voltage controls current, but it doesn't work the other way around. There are transistor circuits in which input current will control output voltage, but that's

Hey, when you're not up against a deadline, I'd like to hear more about this project. I dream of doing similar things :) -- Z

right.. i *did* previously realise that in the v=ir equation, smaller values of r would mathematically increase v, and larger would increase :) i'm waay shagged out, and haven't got any results any

okay, v=ir, right. i've tried using resistors rated at a fraction than an ohm, but i'm not getting any increase in voltage, and all the amplifier info i can find uses a 'signal' voltage and a

I recall a book called 'Electronics 101'. Is it still availalbe? Where can it be found (online store?)?

Cool. Glad to have been of help, even if I barely had a clue :) Anyone know how to quieten a switching power supply for use in audio circuitry? I have a cheapy power supply laying around, and am

Funnily enough, your comment re the true earth provided the answer, thank you. I rearranged it, and it works like a dream. Arcane it may be, but it works very well:-) I thought the design looked

"Dominic Rivron" <karen.rivron@...> sez: Wow. Truly bizarre. I am too new to all this to comment usefully on such an arcane construction...what the hell is that transistor on the inputs for?

Hmm. Did you build it straight from the app notes, or some other schematic? Can you point us to the schematic you used, somewhere on the web? The hiss might be from lack of a true ground... I'm new

Hi all Great site, and just about at my level being fairly new at this game. I am a pretty keen radio monitor on both VHF and UHF as well as HF. I am very keen to get my hands on a circuit for a

If I'm not mistaken, there's a +15V gain on the LM386.... I think I read this from National Semiconducter's PDF file on constructing sine wave shapers...look on google, in the PDF file there's a

I've just built an audio amplifier using an LM386, and found that though it amplifies, there is an annoying level of backgound hiss, irrespective of the volume setting or input. Also, it tends to

There are a lot of different ways to do this. You can spend a lot of money and not so much time, or a lot of time and save some money. PLCs (Programmable Logic Controllers) are well suited for this
