A lot of this was already done when I posted the other day was just waiting for paint and glues to dry.
city water tower #2
Attention was then turned to the tank, secured the top to a 3" PVC pipe cap and made it a snug fit so the top could be removed to access the electronics for the solar panels and blinking red LED on the top. I ribbed the outside of it for seam lines and also the top in pie shaped pattern. When finished the tank will be glued to the cat walk and the catwalk will be secured to the tower by 2/56" SS machine screws. Not knowing whether I might need to access the bottom where the wiring for the 2 solar panel would enter and made removable also securing again with 2’56’ SS machine screws. I spent quite a bit of time figuring how to make the red LED blink using pathway solar lite parts. Most inexpensive pathway solar lights are powered by a 1.2vdc battery that is charged by 1, 1.5 volt solar panel and that is boosted by a joule thief or in my case a converter, which looks like and is marked the same as a resistor. The self blinking LED I had selected uses a IC to make it blink, I selected this over the other option which required a circuit board and some components, KISS. Only problem was the converter inferred with the IC causing it not to blink. Back to the drawing board, I removed the converter and soldered a piece of small wire in its place, now had a 1.2vdc circuit that was to power a 2.5vdc LED so in added a second solar panel in series with the first giving a charge of about 2.8vdc and removed the single battery holder replacing it with 2AAA rechargeable batteries. Would like to thank the folks at lighthouse-led’s on eBay for their very valuable assistance in helping figure out this problem.
Remaining is finish the wiring, securing the tank to the catwalk and catwalk to the tower, + painting of the tower which I will update in stages.
City Water Tower # 3
Work is finally progressing on my 30/40ths city water tower. After a set back in the circuit for the flashing red LED at the top and finding that the theory was correct but the cheap components used in the pathway lights was not. It turned out that by removing the converter (voltage booster) in order so the IC in the LED would flash, I had lowered the necessary voltage below it’s voltage threshold and in order to compensate I had added a extra 1.2vdc battery and solar panel… But this extra voltage could not be handled by the chip imbedded on the small circuit board. So for about $5.00 was able to purchase parts to make my own which I hope will work. Could have been finished 4 weeks ago had I not insisted on making the pathway light circuit work. Oh well learn something new everyday and that’s what make getting up in the morning, fun.
Spent quite a while designing and building the ladder for the tower using 1/16" brass rod all soldered together 1 step at a time. Little difficult as I/m currently taking a med for a lung infection and it makes me shake more that normal, but after I got the rhythm right it wasn’t too bad. Bounce 3 time, solder bounce 4 time solder, etc. Left to do is the new circuit board, LED light, wiring, adding the bowl to the bottom of the tank and fixing the tank to the tower. Piece of cake. Think I will also add a radio antenna to the top, like they use to do to sky scrappers so the could have the tallest building in town, currently the stricter is just over 28" and is a little sorter than I wanted but was necessary to cut shorter to compensate for the tank diameter
This is coming along beautifully!
