Re: Low buck projects- Let's see 'em!

Tired of burning up AAA batts in my LED "track" lighting; I set about to source a power supply. Rummaging around in the bin, I spied one of those component phone charger cig plugs. 5 v in either 1 a or 2 a via USB plug. A few minutes w/the VTVM and polarity was determined. SOlder up the leads to the connector and GtG!

Wired 'em up this weekend and Wallah!
Bright and never-ending power for three, four head, three LEDs per, track lights

Cost?? Well,tthe Stop'n'Rob has 'em in parts'sets for near $6; so I suppose tthatt's less than a C note! A bit of wire and solder here on hand. Now, to route the witre between tthe inner liner and the overhead 'glass!!

Fair enough. Still a good idea.

Re: Low buck projects- Let's see 'em! (Cheap Transducer)

Latest low buck project...

Needed a new depth finder, as the 70's vintage "flasher" had seen its day. Purchased a cheap Hawkeye sounder (digital readout only) as the transducer could be mounted inside the hull. Well that didn't work as advertised, and the only location inside the hull that was somewhat horizontal, was aft of the keel.
Anyway, we needed a thru-hull transducer which was going to cost almost twice the original purchase price. Hawkeye would credit the difference which was nice, but put the project on the shelf.

Now that we are about ready to go, the project got moved to the top of the list. Hauled out yesterday, and took a look at the old transducer, which has hidden under some salon drawers. Much easier to see from the outside.

Nice deep fairing block, old but in good enougn shape to pattern from. The old transducer was bronze and weighs all of 2 lbs.

After removing everything, made a dupe of the original fairing block. Cut the threaded bronze mount tube off the old transducer and drilled out the epoxy fill.

The new epoxy molded transducer has top castings to fit the included transom mount that stand about 3/8 inch proud of the top of the transducer.
Chiseled a hollow in the new mahogany fairing block to fit the castings with some extra clearance. Threaded the mount tube into the fairing block, passed the cable through, and plugged the inboard end with a bit of butyl tape (temporary). Checked to make sure the new transducer fit flat into the fairing block, and mixed up about 3oz of Raka Epoxy. Lifted the transducer just enough to pour in the epoxy and kept filling till the mount tube and the cavity were full. Then pressed the transducer into its home, and used the overflow and extra to seal all sides of the block.

Everything gets gooped with 5200 in the AM,, and stuffed in the hole. All recycled material. Total cost, maybe a dollar for the epoxy and a chip brush.



Old bronze transducer after tubectomy. New tube grafted to fairing block / transducer.



Bottom view... I think I can live with the drag.

Then it falls under the "Inventive" category and gets full marks.

Plus if you have the toys you want to use them! For me with a cordless drill I don't think it would take 10 min!

If you value your time at more than about $0.50/Hr those home made ones cost more than the real thing. I've still got the ones I bought in 1977.
