What is it
swalker20013 years ago
Went out and found this cache over the weekend. It is really cool and I only had to say the code word twice with my Texas accent to get it to open. This is my new favorite cache.

well done , looks like fun. also how long does the battery last?

have you considered a hand crank generator like on a emergency radio as long as your 3 volt back up battery is good?

anyway, im impressed and will be one of my favs.

intially when we were dreaming it up we had thought about that then somewhere along the way we forgot about it. But were gonna go out and try and make some improvements before the summer rush so thats a good idea. Our next one is gonna be moris code activated so that might help there too

Try a rechargable battery and a solar panel?
DELETED_jorgegunn (author)  gtoal3 years ago
we thought of that but because we are trying to hide it and we couldnt think of a way to get a solar panel in place whre it didnt disturb the area or where it could be easily stolen. But if you are making one on your own property or where it could be hidden and still get sunlight that would be great

what is the battery life ?
DELETED_jorgegunn (author)  ordiedawg3 years ago
We arnt exactly sure as we have only been testing it in the field for a week or so. it has 2 batteries the coin and the 9vlt. We expect the coin to work for awhile as it is used to keep the memory working. As far as the 9vlt which runs the majority of the circut is only used for the few seconds it takes to open the cache. We used one 9vlt for the month we were building and testing and it never went below 8vlts which is whats needed to lift the solenoid high enough to release the cache. I will post more about it as we learn more as well as some of the other problems we have on the field. It has been raining and snowing here so I guesse soon we will know if the electronics tube is realy as air tight as hope. Then all we have left to know is how it reacts in the hot texas summer.---- thanks for the post--- jorgia

Fantastic job. Had so much fun seeing it in action
Truly a top shelf idea it is well implemented and extremely well documented.
It is easy to see you put a LOT of work into the instructable
Good luck in the contest

WOW! I am impressed. I am sending you a patch! I am also the President of our Robotics Club and will be posting a link on my Facebook page.
Thanks me and my Father worked realy hard on this he is and embed systems engineer and we have been making electronic progects together since i was a little Girl. This was the hardest and most fun by far. But I'm sure right after I finished them i felt that way about all of the things we made. Dose your robotics club have a web page or FB fan page? I would love to check it out if you do.
I have been toying with the Idea of starting a FB page BUT I might be moving across state in October and I don't know if I can transfer the page to the new President. Something to check out. We have meetings second saturday of every month and I also teach robotics at Western Oklahoma State College and it is open to anyone as a adult continuing education so moms, dads and kids take the class which is a BLAST! My dad and I started building robots when I was nine and he is a Automation Technician for Phillips Petroleum and so was his dad. I teach robotics, Constitutional history, invent and also repair Biomedical Electronics. So I'm keeping the technology gene alive!
you can switch moderators for fan pages. I had one in Ky for a club i started and they still run it. That is awesome that you and your dad share that i feel blessed by my dad and his passion he has passed on
