With that said I did put together a cheap electronic clock from Amazon before doing this project to give me some practice with the soldering iron.
So here's what I got done before I shorted out my project like an idiot. Yesterday I soldered the RaspberryPi to the MintyPi board. After I got the solders all flat and tested with the multimeter I moved onto the screen. I a hard time with the screen because my cut too much off of one corner but after some finagling and patience I got it to work. Went ahead setup the SD card, booted it up and everything worked. After I got all that done I called it a day because I had to borrow a drill from my friend to do the tin and start the other half.

Here is where I screwed up and immediately realized it. I had the board and screen sitting on the tin/battery assembly before putting electric tape on it. Then I plugged the power into the RaspberryPi instead of the power board, saw a puff of smoke, noticed the battery "DONE" light was on and then realized I screwed up. After that I desoldered the wires from the battery/tin assembly and plugged in the MintyPi to see if it was still working. And now it's only showing the backlight on the screen.

-I'm pretty sure I bought the wrong gauge of wire. I had the same wire that was mentioned in the build video but I think I might have changed that somehow last minute in my Amazon cart.
-I don't know very much about how to use a multimeter. Especially because a lot of online tutorials show the more high end ones. I figured out checking the resistance and the voltage but I don't really know what all the options for each one means.
-I'm sure my solders are horrendous just from looking at some of the other projects on here. Let me know if they are so horrendous they might be part of the problem.
Here are my questions for you guys that have much more experience then me.
-Is it possible to use my cheap multimeter to find out what might be shorted out?
-If possible how can I do that?
Thanks for reading any help is appreciated.
