You can always put it in a plastic box with some packs of silica gel in it.  If you have to run wires into the box, make a hole and seal it with silicone caulk

I'd be interested too.  I live up in McKinney, so I'd be more likely to go to one that is in Collin Co.

Mine is running a bit fast, but I think it is only a few seconds per day.  It does do a lot better than the clock on our kitchen wall, though

A few months ago I built an analog clock using my Arduino.  It is written up in the current issue of Make Magazine.   It has an decimillia driving 3 amp meters.  It is is all in a nice wooden box with an antiqued finish.  feel free to ask questions about it

What all would I need to do to put the build together?  I got a linux box and a spare afternoon

Why is it the linux version always seems to lag behind? Shouldn't it be _easier_ to develop for linux than other platforms? I hate to think about how hard it is to programs for mswindows

Look down at the bottom for the library to emulate a ps/2 device

When you use and accelerometer as a mouse, the over riding acceleration will be due to gravity.  So the mouse will respond more to tilt than to motion.

you could also have the arduino emulate a ps2 mouse.  and either connect directly to the ps2 port on your computer or use a ps2/usb adaptor (these are typically $5-10 and do both keyboard and mouse, the small ones that come with your mouse are typcally only a plug converter).  This pay you just plug it in and go.  I would suggest using the adaptor so that you don't run the risk of damaging the ps2 port.  BTW the ps2 library in the playground only implements the host side of the protocol and not the device side.

Just out of curiosity, what type of enclosures are yall thinking of using for your clocks?  I did mine in a black wooden box because it matches our decor.  But the other idea I had was to use a metal enclosure that looks like it should have been mounted in something like a Nasa control panel

hi all, can someone point me to some online retailer that sells 1mA analog meters?... i've found a project that requires three of them, but i can't seem to locate any online!... i found hopesun, but not anywhere to actually buy them...

thanks,
isaac

Unfortunatly the place I found my meters in Dallas, Tanners,  doesn't have an online store either.  Cool store though, its filled with cardboard bins full of parts.

 I recently ran into this issue myself. The digital outputs on the Arduino can only supply 40mA.  Odds are that motor needs a couple of hundred mA.  Because there is a limit to the current, and the resistance of the motor at rest doesn't change, the voltage will drop to the point where V=IR.
