Step 1: Tools and Parts Needed
(1) Empty Altoids Tin
(3) Rulers, paint stir sticks, or I used banister rail spacers
(3) Guitar Strings (I used the top 3)
(1) Old BIC pen
(1) Some plastic (credit cards work well)
(3) 3/16 x 2 Eye bolts
(1) 1/8 mono jack
Drill with various drill bits
Hot Glue Gun
Step 2: Make room for the neck
WARNING! Make sure you are cutting on the correct side. You want the nice Altoids logo to be displayed correctly when playing it. I am right handed, so I made the cut on the right side of the tin.
I used a drill to put holes in the box. Then I used a small knife on my multitool to cut the box out.
Step 3: Cut holes for the strings and the 1/8 jack
You also need to make a hole for the 1/8 jack. I used a slightly larger drill bit and then bored out the hole with a pair of needlenose plyers.
Step 4: Cut up the BIC pen
I also put 3 notches in the pen for the strings to rest in.
After that, get out the hot glue gun. Apply a nice layer of glue on the BIC pen piece and put it on edge of the lid, above the strings (see pic)
Step 5: Attach the 1/8 jack and insert the neck
NOTE: If the ground plug touches the case, this will not work.
After you know everything will fit, put some Gorilla Glue on the bottom of the case and slide in the ruler (only 1/2 way or as far as you can go without hitting the jack).
After that glue was set, I covered the whole thing with glue from the hot glue gun. Just to seal everything up and make sure the ruler will not come apart.
Step 6: Working on the neck
Cut the other 2 rulers you have down about 1 inch smaller than what is sticking out of the Altoids tin. Get out the hot glue gun. Glue down the first ruler. Then glue the plastic down with the tab sticking up. Then glue down the final ruler on both the plastic and the middle ruler.
Step 7: Finish the neck
Step 8: Wiring up the piezo
Once it is freed, wire it to the 1/8 jack. Follow the diagram that came with your 1/8 jack to find out which is positive and which is negative.
Before I glued it to the case, I drilled a very small (1/16) hole in the lid. Center the piezo on the hole in the lid and hot glue it down.
Step 9: Almost done!
To tune, just turn the eye bolts to add tension to the string. Then tighten the nuts to keep the bolt in place.
Then plug in and play!
