Microcontroller thread #4!!!

ur university doesnt have it?

well, sure, but how is that a project?

here is a list of a bunch of projects. none of them jump out at me, but maybe you guys can look at them and think of something that is not on the list.http://www.hobbyprojects.com/M/Microprocessor_Circuits.html

maybe I could do something like this(juice mixer):
http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2005/lp78/Website/Final_Project.htm
or I could start with something like this(x-y plotter) before I jump into a milling machine:

here is the page I got them from:

here is something you might like. a couple actually.
recieve morse code transmissions, display them then answer.
or
recieve a code that is unknown then decrypt it and retransmit.
this second idea comes from this thread:

eh, seems kinda simple. well, encryption/decryption can get as difficult as you want, but does not seem as much of an engineering problem as a math problem.

 

A weather station with digital LCD display. The sensors are easy to get. You can make it as simple or as sophisticated as you want. You can even get wireless chipsets for short range use.

Good luck with whatever you choose.

 

hmm, what wireless chipsets are you talking about? that would be an interesting idea. I find telemetry interesting and nice to put on a resume.

mean something like this?:

Yep. Be thankful. I designed a wireless system with an RF engineer long before there were fully integrated chipsets. Kind of a nightmare.

 

heh, I can imagine.

 

These days it's often a single chip. I know I would appreciate it if I got around to actually building wireless communication setups.

 

One minor use for a microcontroller is to capture the correct time and date from the WWV time signals. I wouldn't mind having an alarm clock that automatically updated its time and also worked when the power was out.

 

I think I am going to do wireless! this chip looks good:
http://www.chipcon.com/files/CC2420_Data_Sheet_1_3.pdf
I still have to look into what kind of firmware I would have to write (if any, chips seem to be getting more and more plug-and-play). I would like to make it have write access to a .csv and simply write files into a folder for telemetry data.

so, wireless sounds good, now what should I do with it? weather station sounds ok, but I am open to more interesting ideas. what kinds of things would it be interesting to monitor?

its late, hopefully I will have better ideas tomorrow.

 

no posts? I will be back later

 

hmm, this looks promising:
http://www.maxstream.net/products/xbee/xbee-oem-rf-module-zigbee.php

I could get myself a couple of those, but I am not sure how I would communicate with a pc when I have one of them taking up the UART on each side.

 

wait, I guess I could get a microcontroller with 2 UARTs (like a atmega64)

 

heh, in trying to find ideas for how to use the Xbee wireless module I found my own thread in google. thats sad =/.

anyway, if anybody knows of something cool I could monitor with a microcontroller (and wirelessly communicate back to a computer) I would appreciate it.

 

Those Zigbee modules have an extremely wide bandwidth, enough for several video cameras. They look like they are compatible with things like wireless Ethernet routers. Mouser has some for around $23.

One thing that I would think of would be security cameras to monitor the car.

It's a bit of overkill for an indoor/outdoor thermometer.

 

microchip.com offers microchip samples free.

 

maybe. but I was looking for something more unique.

thats what I was thinking, but I have no ideas about what to make.

thanks, but thats not really news =]. pretty much all big chip makers offer free samples.
