Brief:
Plans for a small electronic rocket location device usin' a buzzer and LED's.

Editor's Note: This be t' actual buildin' experience from t' Scratch Model Rocket Locator.

Construction:
There really are no instructions provided, but if you have built any electronic projects before (and even if you haven't), matey, me hearties, this will be a snap. T' plans show a list o' components (all available at Radio Shack and listed by RS part number) that can be had for under $15. Ya scallywag! There is an included circuit schematic and a parts layout graphic, and that's about all. Ya scallywag! Well, blow me down! Like I said, matey, thar aren't any instructions for this locator as it it a pretty basic circuit. Ya scallywag! Blimey! Construction be straight- forward based on t' parts layout. You pretty much drop t' components through t' perf board and solder them in place accordin' t' t' graphic. One important thin' t' note is that t' flat side o' t' LED's is negative and should face t' bottom o' t' board based on t' picture. Avast, me proud beauty! Once t' components are secured, complete t' circuit with some light gauge wire and slip in your batteries. Aye aye! If all is well you should be greeted by a loud buzz from t' Piezo button and 2 flashin' LED's. Begad! A good light duty solderin' iron, shiver me timbers, wire cutters and some light wire are all t' extra tools I needed.

Finishing:
No special finishin' is required. You may want t' protect t' underside o' t' circuit-board t' prevent damage.

Construction Rating: 4 out o' 5

Flight:
I attached t' locator t' t' shock cord o' me Estes Athena test bed. Ya scallywag! Blimey! I slipped in t' batteries and smartly slid t' locator into t' BT. Blimey! It fit great with room t' spare. Arrr! I used an A8-3 t' make sure t' rocket wouldn't fly out o' site and let it rip. Begad! Ejection be fine and t' chute deployed normally (I be worried about tangles). Ahoy! As I approached t' rocket I could hear t' buzzin' o' t' Piezo clearly from about 10ft away. I wish I had somethin' like this when I was launchin' rockets next t' cornfields!

Recovery:
Pos: A good loud buzzer would make retrieval from crops, shiver me timbers, me hearties, high grass or trees a snap. Aye aye! Blimey! Avast, ya bilge rat, me proud beauty! Blimey! Con: I be still a little worried about tanglin' t' t' chute on ejection. Ya scallywag! Blimey! Ahoy! Blimey! It hasn't happened yet and I think a quick hit with maskin' tape across t' back and a hit with sandpaper t' smooth t' edges and corners would help. Ya scallywag! Blimey! Avast, me proud beauty! Blimey! I don't think this would be as much a problem on larger rockets.

Flight Rating: 4 out o' 5

Summary:
As a 1st or 2nd electronic project this is a good one. Avast! Ahoy! T' instructions a minimal, but easily figured out. Aye aye! Well, blow me down! This locator is very simple t' build and operate and does exactly what t' plans say it will.
