So if i actually make this will it work?

Reid G 7 years ago

So does it work or not. I'm not making it if it doesn't. You have a comment from a few months ago that says it doesn't actually work but another from a couple years ago that says it does.

It does not work, however, the concept works. If you want to improve on the circuit schematic, I am sure you can get it to work. Good luck!

This is a really cool concept! So much can be done with this information! Thanks for sharing!

pleaseplease!! i need help! does it ACTUALLY WORK i need it and i CAN NOT WASTE TIME

In theory, yes. In actuality, no. I put the design up here with the hope that somebody else would be able to make it work. I am sorry for any inconvenience.

So, I will try to be nice but did you when you did your school project give the correct credit to a girl who did this many years ago? I certainly hope so, In most schools today this would be a failing mark if you did not. Good work, nice instruction http://www.extremetech.com/extreme/160003-15-year-old-girl-invents-flashlight-powered-by-the-heat-of-your-hand

I'll try to be nice, but this girl invented nothing, this isn't plagerism, just like plugging in a light bulb into an electrical outlet doesn't get you a plagerism citation just because someone did it before you

I'll try to be nice, if you actually did your research you'll find that girl invented nothing new at all, I should also mention a site called thermalforce has been selling similar flashlights almost a decade, how I know this? I too had the very same idea.

Hey....I tried to make it too. But, my flashlight is not working! I've used the same things you have but the TEC12706 instead of the one you have...
Please help me!!!! I have to submit it tomorrow! Please!
Thank you :)
