I got bored one night and wanted a cup of tea. So being the tinkerer I am I made a hacked together tea maker. Right now this is more of a description than a guide but I will happily answer any question I get in the comments.
Step 1: Ingredients
tea bag and mug (of course)
Basic coffee maker (one you can afford to lose)
Oven thermometer (so you don't burn the house down)
6v power source (I used 4 AA batteries)
Step 2: Part 1: Boil
To boil my tea I used a coffeemate coffee maker (with the top part removed) as a hot plate. Slow but cheap. To disassemble simply take out a few screws and remove any piping. There is currently a melting plastic scent coming from mine so make sure to remove all piping before turning it on. To monitor the temperature of my tea I used a digital oven thermometer. This is the only unmodified item in this instructable.
Step 3: Part 2: Stir
To stir my tea I used the typical computer fan, magnets, and a scrap piece of plywood. There are plenty of Instructables on how to build this so I won't be going into great detail. If you wrote an instructable on how to make a stir plate I will gladly link it here.
Step 4: Part 3: Enjoy!
This project went from idea to published in one night. There are probably tons of ways it can be improved.
The main points are:
1. Bored tinkerers are dangerous beings
2. Mundane tasks can be sources for fun projects
3. A cup of tea is so much more fun when you use a magnetic stirrer. You get to watch the spinny vortex of doom.
