So even though it's January, I went camping this past weekend. When I came back from camping, Lo and behold I saw on my desk a cell phone! This gave me the ability to realize a dream I have had since I was in high school: To build a remote detonator to use with my Thunder B airsoft grenade. For those of you who have subscribed to me since I first became an active member of Instructables will know that a) most of the airsoft stuff I make has either exploded, or been really super sketchy, and b) I have not submitted an airsoft related instructable in quite some time! This instructable will solve both of those problems. First off, I have come a long way since my backyard, blow 'em up style of game play. I have attended several indoor games and milsim ops, both of which do not allow the use of explosives. However, most of these places will allow you to use certain kinds of "grenades" such as the Thunder B
airsoft grenade. Note that this grenade does not actually cause a bb strike, but most places will play with "radius rules" in order to contain the realism and allow the use of grenades. What this device does, in a nutshell, is cause the pin to be pulled on the grenade, causing it to explode. This entire project can be done for under $20, assuming you already have a few parts lying around. This does not include the monthly charge of the tracphone, but considering the cost of some commercially made airsoft equipment out there, that is relatively cheap. Also, you will have the ability to detonate this anywhere that you have cellphone service, something you cant get with any other available device!
