Hope everyone had a happy Christmas and is looking forward to a good New Years's. Anyway on the topic of PCB making etc I'm still looking for a good source of...
I've used that in the past. I found I could do large traces ok but when I got smaller I always had issues in transferring the image to the copper and would end...
... I have one of the Kinsten ones and they are not THAT nice. The exposure level is pretty high but not very uniform. Thats why I want to make a new one as...
I found the UART code from Appnote 305 to be useful. Here is my code for it. Please note I've cut and pasted this from my code so it might not actually...
Yes I'm sort of ready. I'm yet to actually see the racetrack so that is why I'm "sort-of" ready. My homebuilt track is good :P So yes lets set a date and...
Hi Nigel, Thanks for that, unfortunately that is the code I already have :(. I think my issue is with using the "event" driven method instead of "polling". I...
I confess, I don't fully understand what the issue is you are having. So don't shoot me if I've misunderstood. Anyway, my suggestion is to view the Tiny45 as a...
The UART code I am using is one I wrote almost a decade ago when AVRs where new and fancy. It is interrupt driven and has soft flags for RX_Complete and...
Change the pin definitions for the TX and RX pins if you did not use the same pins as I did. Assemble code and burn it to the tiny 45. Hook up the TX/RX pins...
I am going to work on version 2 of the stock car project and would like input from people. ... Comms - should I go with 1 Pseudo open collector - single master...
Yippie!! Love all the other stuff - Motor driver, IR and line sensing. The only other thing missing i guess is ultrasonics? ps: RS485 will do (IMO) but i'm...
... Good-o. I assume that means you must have a set of software written. We all must be close to ready to have all our bugs come out at once with every- one...
What about TWI (I2C) as the multidrop protocol? I know it has limitations but it does have the advantage of being popular (ie it is easier to find sample code...
... I2C is a bit lacking in robustness. It is not as immune to noise or damage as other things. I would probably put it down the list from single wire UART...
Yeah you're right of course, I2C is not the best, especially near motors. I'll leave 400A drawing motors for Version 3 discussion ;) Yes, furry cars with...
did that UART code help ? Do we have several cars ready to go now. Would people prefer to have a get together and help each other sort out problems before we...
Hi All, Sorry had the in-laws for a few weeks and have been getting the kids prepared for the school year (they grow up so fast :). Work is also ridiculous,...
Just pulled out my code earlyer this evening, but got scared by all the cobwebs and dust.... then again it could be the cobwebs and dust in my head which...
I'm needing help in refining the electronics on one robotic duck. The Duck stands at 5ft 10in. It has several movements and presently I have placed it on a...
Hi Russell Most of us on this list, like yourself are hobby robot builders. If you take some photos of your robot and ask specific questions about what you are...
... I have not played with those specifically. However the sharp range sensor modules use to be problematic with different surfaces. Still looks like an easy...
... Hope about we try set a date then? I am good for 8/9 or the 15/16 of March08. Could make it sat to help people get running and sunday to try race?...
