what do you need measured

... visions of students running around the room waving accelerometers going "brrrrm! brrrrrrrrm!"

nah, they're 2 smokers..."nnniiiiiiiiiiaaarrrr, reninininin, nnnniiiiiiiaaarrrrr....."

hahahahahahaha. As to the cost should be using a pic processor so they not to expensive. I have to have a cost plan made out by the end of next week. So i'll post the final cost of production then. As to the question of space i will see if i can interface it with a flash drive/ removable hard drive which will give me ooooooooooodles of space to mess with. hmmmmmmmmm. the devices used for measuring stuff can either be bought or made, the latter might be cheaper so i'll see.

[Drunken Monkey]

oooh! That's piqued my interest.

Removeable CF or SDIO would be better than a download via USB/Serial in my books!

[aff-man]

was having a chat about it today with a guy who has used pic's and a removable hard drive and it would be easier to handel but the coding to make sure all the info got stored right and retrieved might take some planning hmmmmmmm. Lecturer said i could use a flash drive. Would make comp program easier as well. oh well we'll see. Co-incidentally i am also doing a bit of research into making just a standardized lap timer so if there is anyone out there who is in the electronics industry who can recommend a chip that has +- 256 bits eeprom, can run at say hmmmmm 2+ Mhz has 2 ports and hmmm that's about it.

You want a Mitsubishi M16C with integrated flash and RAM, you do. Cheap as chips and you can clock them up to something over 10MHz. The bespoke embedded electronic designer's standby.

It has a 12-bit A2D module as well IIRC, I'm sure you could come up with something interesting to do with that in a bike datalogger.

CF and SD cards can easily be bitbashed out the CPU's data bus with a few extra I/O lines. I've done software-driven interfaces for both in the past.

got the big OK from lecturer. But he said i would have to simulate bike movement using lab inputs because it would take to long to set up the sensors on a big. Well i will do as he says but i might spend some dosh and design/build/mount sensors on my bike anyway and use the programmed processor. To see if it works practically with no thought of personal gain . hahahahaha so let the planning begin

A tech student did a dyno project some years ago, before going to foreign parts as a missionary or something. HE gave me his setup, including a test rig and source code (?). No use to me (didn't have the skills to finish it off properly) but if you want it, its yours. To good to throw out...
It is in the attic at home, so either wait until i am home agian (mid term) or I will get the missus to dig it out. Let me know.

hmmmmm maybe with a few brains in here we cam get it up and running and use it to the benifit of all KBr's. It would be cool to have a dyno day that didn't cost anything. I'll be willing to have a look but with current work load a little wait might be in order.

As to the mitsubishi well it might be over kill but i'll see.

Have a look at this, 190 pounds sterling (~$550NZ or so)

Hmm interesting. I have run into a snag though. The low level code that is needed for file sorting on the usb drive will take ages to work out. So if anyone has an idea how to do it or a site that explains it then whoo-hoo we are ready to go.

BTW i can probably get a lap timer with LCD module for under a hundy from tech will have to see though.

Well, I have a (homemade) dyno, and when I am back in Auckland for longer than a single weekend, and have sorted out the power supply problem and tweaked the calibration, will put out a general invite. I will have to come up with a bulltproof disclaimer - having lots of bikes through the machine would be good for my testing, but no way am I going to wear the cost if something grenades.
Watch this space - probably towards December.

One that is set off by IR or manually?

Hey - talk to Jimbo - it appears he could need a hand measuring things - he seems to have a liberal interpretation of length and height

Eh? What exactly are you talking about? A FAT implementation, or something? Or do you want to implement a USB master controller so that you can use generic USB storage devices for output?

Be more specific, I can probably get you what you need.

IR

As for the code i need to basiclly get hold of the c code that does the file sorting in the usb (basically the driver) i can get more info but the problem is, i need something that is effective but quite small so it can fit on the pic controller. If i can't then i will use a flash ram extension through one of the ports

I still have no idea what you're talking about.

What is the usb of which you speak?
