Solar rechargeable fire starter

Picture of Solar rechargeable fire starter
This little fire starter can throw quite a spark! it is a hacked camera that uses the high voltage stored in the capacitor that is intended for the flash function as an imitation ignition method for starting fires! I have been stuck trying to build a fire and I know I'm not the only one. Because of past issues and the near future summer camping plans I decided to make this little guy. Watch the video for a demo and we will get started! 



DO THIS AT YOUR OWN RISK. there is high voltage stored inside of these capacitors that can easily pose a risk. I am not responsible for any damage or injuires.

You might want to try using a thyristor to protect the safety switch:

1- If it was turned on while the capacitor is charged and the leads are touching.

2- It will fail prematurely due to the high current running through it.

Another option is to use a relay that connects the capacitor to the leads when it's activated, may be even activate it from the solar panel to prevent battery dranage.

this is brilliant, as the idea yours?

Thank you! As far as I can say I think so. I haven't seen anything like it but odds are there might be something similar

awesome, I've started building mine already. Thank you for this brilliant idea and sorry about the mistake In the first comment, I ment to say is instead of as.
