Make:

Step 3 : The first soldering

All the leads are ready for soldering.

When you are done soldering, trim all the leads really close.

Step 4 : More component soldering

The last soldering step consisted of the IC socket and (2) 15k resistors. To hold the socket, I clamped it using the helping hands. You could just as easily hold it with your finger.

Step 5 : Adding the power

Finally add the power supply. To hold the wires in place give them a slight twist and clamp them with helping hands. This will give them a little tension and they will stay put while you solder.

All done soldering.

Step 6 : Check your work

Check the battery supply, making sure you get about 3volts.

Now, check the USB plug, making sure you get about 5volts.

Step 7 : The case

My wife was very nice and bought me an Altoids tin and some various candy tins. Unfortunately, they are the mint tins, not the gum tins, and they are too big. Or are they? After tinkering with the all-too-big tins I found that the battery case would fit perpendicular to the MintyBoost electronics. This allowed for extra room for my next project (more about that later).

Step 8 : cutting the opening

I used a cut-off wheel and a Dremel tool to make the opening. My first attempt was a bit disappointing, so I transferred the opening to an orange "Runtz" tin.

Now I'm happy with the results.

Step 9 : Enjoy

It works perfectly, and I can even fit the USB cable inside the tin. Now I can enjoy hours of music on my iPod, all powered from a candy tin. Check back next week, when I make better use of that neat little space inside the RuntyBoost.
