Fun projects you've done with Arduino?

[8bitnintendo]

Anybody here tinkering around with Arduino? What projects have you done/worked on?

I etched a board a while ago (yeah, I know I could just buy one for cheaper, but it seemed like it would be more fun.) With work and class I haven't gotten around to drilling and mounting the parts yet, and hearing about some cool projects might motivate me to get soldering. I'm going to poke around Make and Instructables for ideas, but wanted to see if you guys have done some cool projects.

Nope. Never fiddled with Arduiuno.

I use Microchip's PIC controllers in most of my projects. I design all my own boards and either etch them myself for relatively simple boards, or send out for "busy" boards.

Here's a kind of "general purpose" controller I designed around a 16F887 a few years ago that shows up in lots of my projects. It's set up to drive a HD44780 compatible LCD display, has lots of I/O available including 4 fairly high current MOSFET output drivers, onboard RTC, 128K serial EEPROM, IR detector for use with a remote control...



The last serious project I built was Frankengriddle.

When winter gets here and it's rainy and nasty outside is when I get most of my electronics projects built.

Oh, and here's my battery charger project I started last winter.
It's on my "first thing to finish" list when the rains get here this year.

Voltage, Current, charging time, etc, are all user programmable. It also has an input for a temperature probe to monitor battery temperature and adjust charge voltage & current accordingly.
It should be able to charge almost any type of battery rated at 15 volts or less.
Also has an RTC so it knows what time and day it is so it can be set up to charge at specific times. (top up a battery on a once a week schedule, or whatever)




Sorry, still not Arduino.

here is a project for penetration testing .....

Heh, I've seen that already.
That circuit board shown uses through hole parts on perfboard. It could be made MUCH smaller than that.

Using a PIC 16F684 in a TSSOP package that circuit would easily fit inside a regular ball point pen.

Fortunately I don't really desire such a device...

I saw a guy that put together a whole electronic control system for the electronics in his jeep a while back. I think it was on hackaday or some such.

It would turn the car on, roll the windows down, turn on the stereo, etc with one touch. Pretty cool.

Wow, I'm amazed (reading the whitepaper) that the security on those locks was that bad.

Onity's "solution" was apparently to offer a plug to add to the port that can only be removed by opening the case, and Torx screws to secure it (because obviously nobody has Torx bits...) Their longer term fix is to replace the circuit boards and firmware, but it sounds like they are charging their customers for it.
