Someone give this man a Nobel prize.

I take all credit, everything is my design, the wires are made by me, the DIP switch was set by me, the resistor was bent by me, and everything was bought by me. If any of you guys use my design, prepare to pay the royalties.

Unless you get one as crazy as you. Seems to work out for Jaime Mantzel pretty well. :v:
Analog Devices has nice cases for their stuff

I've completed the schematic and all the values for the bill of materials. I'll get it up in ExpressSCH for y'all to see and critique, ASAP. :dance:
Woops I've accidentally the wrong picture

Success! I made a square wave with variable duty cycle and frequency out of a sine wave. It's still really noisy, but I already have a hunch on how to fix that.
Thanks to SOPA my [URL="http://maxembedded.wordpress.com/"]favourite AVR tutorials site[/URL] is down at the moment. What would be another site about AVR C?

Is your oscilloscope from the USSR?

Work from the datasheet?
AVR C is standard C, at least if you use GCC-AVR as your compiler. The only way programming for AVRs is different from programming anything else is interacting with the hardware registers and peripherals, all of which is covered in the official datasheets and application notes from Atmel.

Yep.
We've just started stocking Arduino products in store where I work! (Maplin)
We've got the Uno, Mega 2560 r3, Mega ADK, proto, wireless/sd, ethernet/sd and motor shields as well as a few books. Picked up a 2560 today.
So it turns out my ALDL to serial adapter was fine, it just was not suited for the task.
the ECU communicates with the computer at weird 7250 and 15890 baud rates which the MAX232 can't handle. Instead I have to use the FT232RL FTDI chip which does the conversion and then outputs to USB. IT does not however output directly to serial which is problematic and I'm doubtful that only this FTDI chip will work for my needs. Anyone else know of a similar chip that can do RS-232 out?

His HV rectifier is going to sell for thousands.
So i'd really like to get into these kind of things, how does this look?

What's a 'behuizing'?
If it's a programmer, you shouldn't need one. The arduino has an FTDI usb-serial converter and a bootloader preinstalled.
It's a plastic box that can house the arduino mega + ethernet shield + 9v battery
Oh, that's fine then.
You're probably going to want resistors, capacitors, LEDs and such.
Maybe a few sensors, too.
What kind of ohm resistors would be most useful? (ie for using leds) and what µF caps?
And do you have some kind of store that sells them in bulk at decent prices and ships to NL? Since i only own some from taking stuff apart, and local hardware stores charge 2 euro per LED etc.
There is no "universal" resistor, you want to buy some from every kind that's commonly used. Add me on Steam.

I highly recommend [url]www.bitsbox.co.uk[/url], they do cheap and fast international shipping and you can get resistor kits that contain a selection of common resistor values, the 1440 resistor kit is great value for money since you don't want to end up having to put resistors in series / parallel to get a certain value.
They also sell an electrolytic capacitor kit that ranges in value from 1uF to 1000uF which is good for most things, however you should get a few lower value ceramic caps as well such as 100nF, 10nF and 1nF which are useful for certain things, if you have the money to spare they do ceramic capacitor kits.
Besides that I'd recommend at a minimum some 1N4007 rectifier diodes, 1N4148 signal diodes, 2N3904 NPN bipolar junction transistors (or similar), a few op-amps, DIP switches, cheap multi-turn potentiometers and grab a pack of LEDs from ebay (the cheapest place).
I assume you have a multimeter, if not I suggest dealextreme for buying one, do not spend less than $30 to avoid buying utter garbage, make sure it's fused (on all current sockets), has autorange, can measure AC and DC current down to microamps, continuity function, diode check function and has decent quality probes.
I've expirienced 220 ohms to be pretty universal for LEDs
Conrad managed to send me 10 huge crocodile clips instead of 10 100µF capacitors, great.
After some talking with VistaPOWA, i'm probably getting this:

And a ARDUINO MEGA 2560 R3
your missing electrolytic caps
O hi guis.
I just finished a project for school, Quadrocopter with an uno and a special shield ontop of it with the gyro etc.
Not much really.
Is this even worth posting?
Oh, DrLuke, I never told you but mad props on that scope of yours. I really do like it. Vintage soviet equipment :D
