Picture of 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!

Heck yeah!! Trust me if anything is underneath this this thing it's on fire.
ok where's jb,
rebuild it so we can burn jb, BUUUURN JB

Well believe it or not, I still have this in one piece. Just not the legs..but they were not very good anyway so I'll try a different style next time I try to use it.
What's the heat it can make? I've seen some produce 1000K+ (melts copper)
JonnyBGood (author)  TheFoofinator1 year ago
Not really sure yet. I'm to the point when paper products are instant fire, but I'm not to the burn wood instantly and melt things point yet. A little bit more work on the frame to keep it from flexing will probably help that.
There's also been a lot of overcast so I haven't done too many tests

Well this is my second attempt at the legs part, still not entirely happy with it so I may post this in the contest. It also doesen't use knex as it's main part so It would be a little strange in the contest

You should try making a stirling engine or something, to use this to create energy. Solar panel!
Oh my god, that's absolutely one of the coolest things I've ever... You should cook something with it; maybe like chicken or something, because I so want to see what happens. :3 You should definitely make a video.
JonnyBGood (author)  DarkOwlProductions1 year ago
Thanks! I actually am planning to video tape this. I want revise the legs, the adjustible hight thing doesen't hold up so well.
Good luck with that, but I still don't think this project is a complete success until you can make dinner with it. :3
JonnyBGood (author)  DarkOwlProductions1 year ago
XD I will deffinitly try cooking something with it.
I wonder what the neighbors would think if they saw you roasting some chicken with this glorious marvel of K'nex engineering...  There's no way that this thing's legal.  I LOVE IT!
That would be boss. XD
Bro, nice job. So, what have you set aflame? A board? A couch? A deep-fried-toasted-seagull-with-a-side-of-awesome-and-some-bacon-to-go-along-with-it?
Well, that's the thing. I haven't burnt much stuff with it. On the best tests I've had, I could stick a cereal box underneath it and it would instantly set fire with a great wooshing sound. I'm having a hard time focusing it so I can do more epic things, but when I do I will make sure to fry up some seagull. XD Not sure where you thought of that but awesome.
Awe, that is too bad. The idea of setting the cereal box on fire sounds cool, but I think that when you get into the more epic stuff, I'll be "more impressed." =D

As too my last sentence about frying seagulls, I don't recommend it. Go ahead and stick with the bacon.
I personally want to melt some metal. That alone would be EPIC!
That would be epic. When (and if) you do, make a video so I can see it done!
Try shooting a laser through it and setting a target 500 yards away on fire! Or you could ignite fireworks with it on the fourth!

WOOO!!!! PYRO!!!
JonnyBGood (author)  nerfrocketeer1 year ago
Yeah! Hooray for enviromentaly hurting the enviroment!! XD No, realistically I don't think shooting a laser through this thing would set some thing on fire. My theory is small beam = small output. Maybe if I had a nice laser though,or my evil scientist side is now thinking maybe if I had like, I don't know, 5000 cat lasers arranged perfectly so they were allshooting directly through my fifty inch magnified glass! Muhahahahahaha >=D

Stop giving me such great ideas nerfrocketeer. My mom is scared of this thing as is.
Just kidding.
Why not use it on a cat! Call it the ultimate cat...toy...
Sorry i have a diabolical mind...
JonnyBGood (author)  nerfrocketeer1 year ago
Okay the thing with being an evil genius, you make potential dangerous things, but never acctually hurt anything.
JonnyBGood (author)  JonnyBGood1 year ago

Genious man... Pure genious...
JonnyBGood (author)  nerfrocketeer1 year ago
I know =D. Evil genius
Are you a pyro too?
Ummm... Maybe... I guess... Kind of... I dunno...
JonnyBGood (author)  nerfrocketeer1 year ago
Burn, fire, burn, flame, smoke, fire, burn...........wait.........No wait. That was nothing.

lol nice,knex pyros =P who knew it could happen =D Thermite still works better though =P
JonnyBGood (author)  Johnhall141 year ago
Yeah thermite is great but who wants to buy thermite when you can get a free giant 50 in. magnifing glass! Besides, I don't know about your parents but mine would never let me buy thermite anyway, they're scared I'll burn down the house with this thing.
lol, true. =P kinda the same with my parents but they are not worried about me burning the house down, more like blowing it up and burning it at the same time XD Anyways thermite has to be made not bought.

Awesome work, great job, shoulda saved it for 1st July :P
JonnyBGood (author)  hunter9991 year ago
Well that's the thing... I don't know the rules. Will he allow other things other than knex, rubberbands, and tape? I use lots of other things with knex so once I know the rules I'll know what I can post.

I can still make a full ible' for this too can't I? (Even though I don't want too...)
Very nice!
AAAAAAah, a ghost in the 8th picture!!!
Ow, it's you xD
JonnyBGood (author)  sandroknexmaster1 year ago
Hey! I thought that would be a great idea to include my shadow with it!

Know you're just kidding. Thanks! =)
