So for the flashlight it was very tricky at the beginning to get all the measurements down and get it perfectly because you cannot make a mistake on the wires are also wouldn’t work in the same thing with the pipe. So I got that and then when I cut the pipe it was pretty hard because you had to really saw a lot and that part was pretty easy thing to little after with my hand.Getting the wires down the shape was very easy and that didn’t take me that long. Drilling the holes Wasn’t that hard either The only tricky part was getting it in line perfectly. The soldering was very easy I don’t know why it took many people so long. Putting the switch designs into the flashlight was OK but not that hard the only annoying part was I had it in and I forgot to put the battery so I had to take it out but other than that this project was very fun and a little challenging.
