I have a simple project, preferably developed using arduino.
The thing will contain a numeric keypad to allow user to enter time in milliseconds.
The LCD will display the time.
User will press a buttion (say #) to tell it to start the count down.
When the count down starts, it will move a servo to one position. Once the countdown reaches zero, it will move the servo to another position.
This should be fairly simple, I simply don't have the knowledge and time needed to develop it.
PM me your price for such a project.

I will also be needing someone willing to help develop an arduino project for btc in the near future.  If you find someone let me know.

Can't it be an normal microchip?
You only need the code, or you want also some kind of PCB with all together?
When you mention servo, it's a servo like the ones used on the small hobby cars?

It can, but I'd rather it be arduino, i like open source, and have an interest in learning it later.
Need all PCB and parts pre-build.
Can be a servo, as long as it can push/release the button at a very precise time. Say 50ms precision.

You're not wanting this to push a power button are you? Because there are easier ways of doing that.

As for the arduino programming, I've done a little work with other robotics -- just not arduino specifically. I do know a bit about it, and where to find resources with it. Can't really tell you if I can help or not without more specifics though (moving from A to B sounds like a job for a stepper motor, not a servo, or maybe a pneumatic assembly).

If I helped, feel free to donate to:

It's all about the game, and how you play it

The cost of programing a single chip and breadboards(or pcb) would outweight the arduino for a one off project and wouldnt be very flexible if you intended to change the design at all later

if he's pushing a button a stepper motor isn't much good it's still rotary like a servo, pneumatics would work but aren't great for predictability due to varying pressure in the system and the requirement of a compressor and electrically activated valves would total more than a linear actuator after very long

What I mean was "if all you're doing is pushing a button, there are better ways to do that (like just wiring in the panel/timer). If you have to do something else, like move it a foot, and do something, a stepper motor might be the ticket."

I've been looking at 3d printers too much, probably.

steppers are great for 3d printers and pen plotters (mpja has a great selection of steppers by the way) not so much for hitting a pushbutton though

all, i am not trying to push a power button. this is not related to mining!

I can do it, will send a PM...

Have developed a lot of projects for AVR, and started out with arduino, it has its positive and negative sides, esp. with the smaller arduino its not that bad a prototype platform Smiley
