Thanks Andrew, I figured that may be the case (always good to hope though :) Do you have a part number/spec for the H-bridge you put in the stock car we are...
The April issue of Silicon Chip magazine has a project for a High Power Reversible DC Motor Speed Controller. It can operate at 12V/24V up to 20A and uses...

Josh Sometimes non local is faster to get, but Ron Nollet might have some in Melb http://www.parallax.com/detail.asp?product_id=29144 This uses a ST chip,...
Hi All, Thanks for the great response on this issue. As I already have a uP with PWM out I have decided to build a MOSFET H-Bridge (Cheap and effective, lust...
... Just look at the datasheets for the IR21xx type drivers and decide which one you want. Makes doing a mosfet hbridge a walk in the park these days....
Thanks Andrew, I'll check them out. Could you please post the part numbers of the parts used in the Stock Car motor driver? Thanks, Josh ... From: Andrew...
... http://www.thehacktory.com/h-bridge-scheme.png OK NO part values at all. It is generic. I will explaine parts. I am doing this on purpose :D The far...
Help!!!! I'm having trouble with the ATtiny45, I can't seem to get the USI port to do anything.... How is every one doing the comms? can you send code...
Have a look at some the Atmel Application Notes that show you how to create a software UART (http://www.atmel.com/dyn/products/app_notes.asp?family_id=607) eg ...
The problem i've got is that none of the code i've found on the net seam to simulate properly, and the couple i have downloaded into my ATtiny45 didn't work...
This is still "theory" however my intention is to set up an async software UART of 9600 baud (or less if its ok), 1 stop bit, no parity, 8 bits data. Use ICP...
I've got some code which i wrote in C (actually copied and modified is more correct) but no matter how i try i can't get the USI to clock using software. How...
... What kind of bug testing have you been doing here ? Are you familiar with the concept of printf debugging and how you can apply it to small systems like...
Hi just introducing myself my name is Justen from brisbane.I make fairly large cnc routers and mills so they are sort of robots I suppose. I am looking for...
... Hi Justen from Brisbane. My name is Andrew from Brisbane (Logan). I make lots of mess :D ... Do you mean "program blank chips with supplied code" or...
Hi All, This may assist you in quickly prototyping stuff on AVR. AVRLib (http://hubbard.engr.scu.edu/embedded/avr/avrlib/) is a bit old now however there is a...
Hi All, If you have any old DOS program or cool hardware that only works under DOS like a DSE DSO MKII or Handyboard Interactive C programmer, like I do, then...
Thanks for that. I have been using DOSBox for running Autotrax PCB software. I did not know how to get it to talk to the serial/parallel ports though. ... ...
Hi Nick, I assume you are trying this on your ATtiny45 motor driver board. According to the documentation you should be able to use the USI for transmission...
Hi all, I am wondering, I have decided my tech skills (electronics) are rubbish but have a great project in mind. Small and simple, but some cool challenges....
Rob, I have built somehting like that in the past for someone but a different purpose. It used old printer parts and the cutter from a scrapped plotter. I...
OK - No one has indicated they are right for this weekend so I shall cancel it. If anyone wants to get any broken/not-working hardware fixed before we finally...
Ok All, This is what I have. Its written in C and written using AVR Studio 4 and compiled with WinAVR. The code is pretty huge and uses 83.7% Program memory....
