Just My Imagination

How can you make a simple circuit that turns something on when a switch is open, and off when the switch is closed?

Like this!



Diagramming took a few tries:


But I got it in the end, sort of:




Now, how do you make one that doesn't drain the battery the whole time?

There's a lot I miss about the Bay Area. But here are some things I like here in Tempe, AZ.

Rent is reasonable!

Cheap and interesting fabric at Fabric by the Pound.

Places to go mountain biking that I need to check out.

Tempe Yarn and Fiber.

Getting great seats at hockey games at the student discount (last time we were in the first row, up against the glass for 20 bucks!)

Foldable! I'll make a tutorial soon.

Time for Tea! Clock
Instruction Guide

Note: This is not exactly an instructable, it's an installation guide for a birthday gift I made. Thought I'd repost it here. The center tin (see pictures further down) is a working clock with one hand that points to a particular tin of tea appropriate for that time of day.


Step 1: Assemble components.
Includes: 6 metal tins, 1 clock tin, and 7 felt magnets.

If you cannot find the magnets, they are probably in the tin all the other tins are sticking to!


Step 2: Add tea
Add tea of your choice to each tin (not the clock one!). Recommend washing tins first.


Step 3: Grab pile of magnets.


Step 4: Place clock magnet on fridge.


Step 5: Place remaining clock numeral magnets on fridge.


Step 6: Place tea tins on magnets.


Step 7: Place clock tin on center magnet. Rotate tin to set clock to correct hour, if you care about that sort of thing.


Step 8: Identify tea according to time of day.


Step 9: Enjoy a nice cuppa.


Step 10: To replace battery (one AA), carefully wiggle open clock tin.

No the tiny pots of nutella have nothing to do with anything. Sadly.
