Skimask,
You said you built a similar thing with LEDs. Would you happen to have the schematic?

Peterdeco1,
That's a very nice offer, but I can just order a few if I go that route. They are certainly cheaper than the other MOSFETS suggested.
Honetsly, I am beginning to think that MOSFETS...
Not sure about the 14C40, but the ISL9V5036, costs almost $4, so 56 of them would be too costly. The Motorola is $2.50, still too much. I'm trying to make this thing for $50-$70.
It may not be...
Thanks for all of the info so far.
Can someone suggest a logic-level MOSFET that they might use for this type of project?
Thanks,
Sterling
OKAY!!!!
This is starting to makes sense. It sounds so cool, I want to build the multiport system just to build it for something, anything.
Of course to make my problem more difficult, I am now...
Forgive me for asking this stupid question, but wouldn't that mean that each '154 would be the same as the others: if output 3 is HIGH on one then it is HIGH on the others?
Another question, which...
Thanks for the book info. I'll check them out. Can't hurt to have them around.
As for how many mags to control at once, all of them. I would assume that I have 2 PORTS available for their control....
What about using a 1-wire network to address each magnet seperately? Maybe that's much more costly. I have no experience with 1 wire networks.
I understand the 1 of 16 decoder, but I'm lost, those decoders have 4 inputs. Two '154 ICs would require 8 pins from the PIC I'm guessing the 4bit counter resolves this, but I'm not clear how.
Can...
Okay, so I'm not sure where to put this thread.
I need to control multiple electromagnets from a PIC18F4550. The strength of the magnets needs to be varied over time, and each magnet individually...
This would be very cool. I'd love to have bluetooth for some of my PIC projects.

I'm creating a silly little thing that has stepper motors attached. They need to run pre-configured/timed sequences. For example, a motor goes CW 60 steps in 1 second, then CW 30 steps in 2 seconds,...
Here I go again:
The problem was that VB buffer(1) comes into the device as buffer[2]
I seem to be talking to myself here, but that's okay.
I just wanted to say that I got it working. I don't know how. But, I ran the original USBDEMO.exe, and then everything started working with...
More info:
In the VB code, if I put the following line "BufferOut(2) = 145" in the WriteSomeData() function, I get "0" when reading on the device, however, If I put that same line in the...
Of course I took your excellent example and tore it all apart to modify it into something completely useless to me.
I'm not getting data from USBbufferin on the device. I am kind of curious about...
Thank you!!!
Maybe I am just tired, but I can't figure out how to do bitwise operations on the lowest four bits of two numbers, without working on one bit at a time.
I saw the masking thread, but it didn't...
I was able to just put the mcHID.dll in the Visual Basic project folder where my project files are located. That solved working with VB, but I still don't have the easyHID program at my disposal....
mister e,
Great stuff. A lot of good things to learn in your example.
So I've decided to make my own version, but I have run into a hurdle with EasyHID. Has anyone had trouble installing it? I...
This message will now be rendered useless. I wanted to delete it, but since I can't, I've put this stupid line here.
Still no thoughts from anyone!
I Tried to use the USBDemo program that I found elsewhere on this forum, but it won't install. Perhaps if someone has an example firmware and driver for sending and...
For starters, there must have been something wrong with my code, but now the device is recognized when I plug the USB cable into the PC, however, it won't install the device driver. I get an error...
I successful got the USBMOUSE demo program working, but the other program, USBJADEM, compiles just fine, but doesn't seem to do anything when I run the USBHIDIO.exe program, which must be downloaded...
