Chez, could you resend it on say MediaFire. Avast blocked the file saying it was malware..
Took apart a 60W halogen lighting transformer, model ET60T-2.

Not much to see really, the two bipolar transistors form an oscillator circuit using a feedback winding that drives the center primary coil, the output is taken directly from the red wire coil which is quite good news for me, means I can mod it for any voltage I really desire.

Still having trouble recreating this on my breadboard. Also is it ok if I use an LED as my diode?
[editline]10th June 2012[/editline]
I swapped out the LED for a siomple diode and it still wont work.

Show a picture of your breadboard circuit.
Edit: make sure you're using the right type of transistor (PNP/NPN).
Before I get some buttons, what is the special difference between "momentary contact" and regular pushbuttons?
No difference
[QUOTE=Stonecycle;36279498]Before I get some buttons, what is the special difference between "momentary contact" and regular pushbuttons?[/QUOTE]
momentary means that it only makes contact (is closed) while you push it, while pushbuttons can also be buttons that toggle with each click.

Pretty sure he wasn't talking about latching switches.
Reread his question then

From the timing, prompted by a certain Mike?
Also, two FPGA boards on their way from Farnell, whoo! Practical VHDL time!
[QUOTE=Fuxed;36283903]From the timing, prompted by a certain Mike?[/QUOTE]
Indeed.
Also repaired optical switch, had a partially shorted 555 timer.

Didn't proof read this especially, let me know if I messed anything up.
It's wonderful, driver circuit cracked me up
I loved the alternative to a schematic. :v:

You'd wonder how many people get that wrong
I need to step down 5 volts from the arduino digital pin output to 3 volts. Can someone demonstrate how to use ohm's law to find out what kind of resistor I'd need?

[url]http://en.wikipedia.org/wiki/Voltage_divider[/url]
Making R1 100 ohms and R2 150 ohms will give you 3 volts out. 100 and 150 are both standard values of resistor so you shouldn't have any trouble finding them. If you don't have a 150 ohm resistor, put two 100 ohm resistors in parallel to get 50 ohms and then put that in series with a 100 ohm to get a total of 150 ohms.
Read up on that here: [url]http://en.wikipedia.org/wiki/Series_and_parallel_circuits[/url]
Also you might wanna read up some on this: [url]http://en.wikipedia.org/wiki/Ohms_law[/url] and print the formulas and nail it to your wall for quick reference.
And lastly to find the color band code for the 100ohm and 150ohm resistors you can use a tool like this: [url]http://www.csgnetwork.com/resistcolcalc.html[/url] if you're unsure.

Could we get a little more info? Is this being used to drive some kind of load, or is it just for signalling?

Here we go, my project is just about complete! I've got a little bit of code-neatening up to do, but I'd love some help testing it
I call it the Internet/Radio Controlled Car - IRCC:
[url]http://thecubeserver.com/tests/arduino/rc/[/url]
It is essentially a radio control car that you can control over the internet. Try it out!
I'm going to post the source code later today or tomorrow, if anyone is interested. To find out how it all works, click the link on that page!
Try not to crash it, and please don't run over my cat :v:
Remember short quick keyboard taps at first
If you find a problem, please let me know
Thanks for the help with relays a few pages back. This is what they were used for. And thanks for helping to test! Hope you enjoy it

That's quite cool. Your cat didn't seem terribly impressed with my driving! It's a shame about the delay on the responsiveness of the controls though :(

Sorry for hitting your wall plugs.
It's fun to play around with, i did notice that sometimes i got stuck when going forward or turning. I'm not completely sure as it might be the lagg that i should be blaming.
