All blocks made except the battery block. Looks pretty good. Could use some laser spacing tweaks though for a tighter fit.

I’ve been testing the new method for making the key with laser etching and acid engraving. I’ve been able to nail down the process with consistent results. Would anyone be interested in this new process? Should I add it to my store?

Just found out that a screen accurate replica of Ralphie's Red Ryder bb gun does not exist. The replicas being sold have the engravings on the wrong sides of the stock. Turns out the factory made 6 models for the actor who was left handed. In order to see the engravings, they had to swap the logo and the compass to opposite sides. I know what I'm going to work on next Christmas.

Finally got around to testing laser etched, acid engraving. I paint the aluminum plate flat black, then. Laser off the paint. Then I soak the plate in acid for about 25 min. These are the first few attempts. Some are too thick, the other too thin.

I discontinued these a year ago, and just found one more in stock. If you want one, jump on it now, because i'm not making them anymore. http://www.replicaprops.com/fifth-element-cartouche-pendant…

Features Cynthia Ettinger as Martha Kent, before Annette O'Toole joined the cast. You also see a different Kent kitchen.

My good friend Marc de Hoogh made me an awesome Stargate RA Necklace. Hit him up if you want one.

Looks cool. Now I have to make the body. Upgraded to a 500mAh lipo. I'm going to be selling this with the cave wall section. I just want to do a bit of work on that since it's literally 15 years old. Needs a little TLC.

Found a nice 400mAh rechargeable battery. Testing how long it lasts.

So a little snag. The cr2032 battery turned out to be too weak for the circuit. Something about the battery having too much internal resistance. Those little coin cell batteries are just not designed to handle much current. So I'm waiting on some other battery options to arrive in the mail. Other than that, it's coming along nicely.

Turns out, the battery was dead. Fresh battery fixed the problem. Duh.

Spent 3 days trying to get the light up key program on the tiny micro controller. The problem is the controller needed a bootloader burnt on first before the Arduino could write the sketch.You would think this is easy, but the tutorials out there are actually not 100% accurate, and made me waste tons of time. Found this little stand alone bootloader burner on Amazon. Plug it in, press the button and bingo bango bongo 7 seconds later the chip is burnt with the bootloader. No more pulling my last remaining hairs out.
