Combustinator, Knex Solar Scorcher





Introduction: Combustinator, Knex Solar Scorcher

Well ever since I've seen the King of Random's videos about a Solar Scorcher he made out of knex, I knew I had to build one for myself. I found a rear projection tv on my way from school one day and that began project Combustinator. This is my second version which features a rail guided adjustible hight on the side supports. It also can be tilted 270 degrees and is very easy to transport around because of it's easy three part design. I am still working to improve the adjustible height feature and the supports around the magnify glass. I'm willing to give more pictures if anyone is intrested about how anything works on this. I must also say while I don't plan to post a step-by-step ible' that may change depending on the rules of the Rod and Connectors contest. I'm not sure they allow anything but knex and rubberbands... Anyway thanks for checking it out, please feel free to comment!

Have you melted any KNEX with it?

No, didn't feel that was necessary. Plus plastic fumes arn't good to inhale.

I meant accidentally like a part fell off or something.

Surprisingly no, when you make something potentially dangerous you do a lot of extra steps to prevent accidents from occurring. All the knex in this build were secured as tight as possible and when something would drop into the beam I had a giant piece of cardboard to throw on the lens, and a hose.... even though a plastic part wouldn't catch fire.... Anyway I didn't melt any accidentally, because I was very cautious when using it.

Okay. What did you all use it for?

Let's see.... I burned wood, cardboard, and paper mostly. Cardboard was fun because it seemed to spontaneously combust.

Heck yeah!! Trust me if anything is underneath this this thing it's on fire.
