Potato-bot | 13 August, 2003

Hello, i had this idea and i was wondering if someone could give me some advice on how to accomplish it. I would like to create a digital recording, like you would find on various keychains, or childrens toys (ex:tickle me elmo). The recording can be short, i just have no idea how to go about doing this, as i know nothing of electronics. Also i would like it to be powered by a potato. What do you guys think?

Any and all who can help me, will recieve their very own "potato-bot" free of charge in the mail. What parts do i need? Where do i get the parts? And how do i put it together?

Thanks in advance.

Jeff- I would start in the great state of Idaho. They are the largest producer of potatos in North America. "Where you can be a spud".

Unfortunatly that is the extent of my contribution. Hopefully it is enough to garner me a Potato-Bot.

All Potato-Bots need power. Look here for your source of potato powered power

Assuming you are not looking into an orchestra sound with Bose loud speakers, you can play the melody with a buzzer creating sounds like the ones from cell phones. The melody has to be stored into a programmable device, such as an EPROM. In order to program the device, you will require a kit, like Basic Stamp, which you can buy from Digi-Key. This starter kit is about $ 200 and the EPROM just a few $ (the smallest is a 8 pin IC). The kit comes with a manual how to program your Micro Computer in Basic. You are ending up with only two components and may not require mounting the components on a board, but solder the potato power supply wires and the buzzer wire directly to the IC. The downside from this set up is, that the IC requires pretty exact 5 V. Dependent on what type of electrodes material you are using in the potato, you may get just 1.2 V. In other words, you will have to put 4 potatoes in series. If you become after that experience an electronic enthusiast, you may want to look into a subscription of Nuts & Volts Please don�t send me my free potato bot.

If you Potato-Bot idea doesn't work-out, try this:

or this:

We prefer combustion [hairspray] type. A word to the wise, don't mix PVC and ABS pipe or glue.

I would suggest using lead-free solder and lead-free components. This would give your kit the "green label".

I dont want the sample if you this suggestion doesnt value add to your project

good luck
