That looks like it was slapped together in 5 minutes, no offense, but spend a little more time on your creations. It looks like it will not even survive a toss. You have a concept, just spend some more time on the timer or whatever you use, as well as the durability part.
Like i said it's just a prototype. The reason I showed this to you guys because I can't finish it. That's why i asked you guys for help so I can make a finished product.
