Boba Fett Rangefinder blinking LEDs

I posted this a long time ago, but I can't find it anymore.
For those who can solder or know someone who can solder, there is a pretty cheap alternative to a fairly accurate blinking sequence that can fit inside a hollow rangefinder. I've never touched a soldering iron before and I did this on my first attempt.

You can find a mini blinking LED kit here and I have found it at other electronic kit sites:

All you need to buy is the 9V battery holder and battery or 2AAA battery holder and batteries (longer wires) and you have nice blinky lights on your rangefinder. You can even add a mercury tilt switch from Fry's electronics and you're set:thumbsup .

Here is a picture of my old hollowed out rangefinder and you can see it fits very well in it. I'm sure it fits better in the other hollow rangefinders (Don't pay attention to the items I Xed out :D ).

The capacitor it comes with is 10uF which is shown in the first video sequence (Thanks to Brak's Buddy for the accurate sequences:thumbsup )
These are just slightly off, but who else but us would know :D.
The second video sequence is a green blinking LED (you should use a red blinking one :lol ) about $1.39 at Radio Shack but you can get it cheaper on-line. I switched out the 10 uF capacitors and used 47uF ($1.19 each).

Depending on which sequence you decide, you can make this for under $15 (borrowing equipment if you don't have it of course;) )
Let me know if this helps anyone out.

Cool Ely!
I was just toying with something like this the other day. Nice work.

Now that is sweet! :D

Economical too! :thumbsup

Very Cool. Now where can I get hollow rangefinder tops from?

Bobamaker does hollow range finders. I am sure there are others as well. Marrow Sun maybe?

Ask TerminalFettler, he does also hollow RF´s and Top with clear resin inlet, very nice work...

Does anyone have a contact information or know how to order the hollow RF's from Terminal Fettler. I'd love to try this out

Send him a PM, that´s the easiest way

WOW that is cool! I will need to try that. If anybody wants one, I can make you a copy of the DP one that is hollow.

i was thinking about doing something like this inside my rubies rf, i was going to try to fit a watch battery up in there

So, buy switching out the 10uf for the 47uf, does that create the second sequence or is that a different kit?

The kit comes with (2) 10uf 47uf capacitor, but you need to buy the 47uf capacitors and a red blinking LED and use those if you want the second sequence.
The higher number of capacitor, the slower it alternates from the first to the second LED.
