    Josehf, as usual I have a problem, being as I hadn't heard back from you about soldering the components together, to get rid of the bread board, and how to protect from the elements, I went a head and soldered them all together. Believe it or not it still worked, yea. I then covered it with silicone caulk and some how in the process I broke 1 of the leads off the transistor. The 1 I used is the S8550 which is shown in your drawing but in the color picture it shows it as a 2N3906, so my ? to you is can I use a 2N3906 in place of the S8550? Thanks as always, Bill

    Well now that I have the Large Scale Central MIK challenge out of the way my be I can get back to some of my unfinished projects, like the water tower and Rosy's rewiring. Should, after soldering all the electric components for the flashing light together, I encase them in something like silicone to protect and keep from having shorts and humidity problems, any suggestion would be welcome. Thanks as always, Bill pictures are of my kit bashed sugar cane train engine made from 4 different manufactured engines, got csn cars and a free lance caboose also that I made

    Josehf, so sorry for not touching base with you sooner, after getting the original circuit working I placed it in a unused location which got some sun and some dark. It doesn't get direct sun light but not in the dark all the time and it is still blinking. Got tied up in another project and sort of put it on the back burner for a while, I'm world famous for that!! I got in the fake car security blinking device and boy is it bright and blinks great, was able to open it up and it's pretty simple in side although it does have a chip LED that is soldered direct to the board but shouldn't be too hard to hack. Was then thinking about used it for my blinker and using the one that you made to light up the side of the water tower to show a town name. and still thinking on that but being as I hav...

    Josehf, sorry about the delay but had to wait for 3 battery pack to arrive, but the wait was worth it as now the circuit works fine, HOORY, I tried it the way it was only swapped out the battery pack which means it turns on and off with the solar panel and I left the 20 ohm resistor that I had in there, I tried it with out the resistor and it would not work so I then tried it with just 1 of the 10ohm resistors and it works fine. Should I try any other resistors or leave well enough alone, haven't tried it in the sun to check charging yet but works fine in house light, I await you suggestion

    I'm pretty much understanding you post, but a few ?s and statements, first my 2 sold cells produce only 2.5-6 on bright sun light, should I add a third? Second where in your circuit am I putting this new resistor? I guess last, am I removing the 100 ohm resistor that I replaced with the 2 10ohms (for a total of 20 ohms)? Last, where to start as being a logical person I usually do 1 thing and then add to or remove and try something else as if one does everything at once and it works, what of what one did cured the problem, as always, Bill

    Josehf, where did that product # come from the one I sent you was # 1512533810566, never mind I found the date sheet and they are the same, please excuse my stupidity, also the 100 ohm resistor was replaced by a 20 ohm one not a 2 twenty's. So if I'm understanding correctly do I need to put a 56ohm resistor into the circuit and if so where and if I add a battery to give me 3.6 vdc will the 2 solar cells charge the batteries sufficiently. where to start, I believe I removed the 20ohm resistor before and it still didn't work but I will try again, if it still doesn't work what should I do next, Thanks , Bill

    Josehf, not sure what you mean with the different resistor values? the only ones I have in the circuit is the 5.6k one and the 100ohm one you had me change to 20 ohms. The led I got from ebay and dealer was lighthouse-led Their #was 151353810566 and the only specs it gave was 1hz flashing, 20ma current, 11,000-13,000 mcd brightness and 1.9 -2.1 forwarding voltage. I did try other led's to no avail, I will wait to here from you, if it is because of a voltage drod from the S8550 how would I increase it, guess I'm just too old school, thanks again, Bill

    Josehf, didn't forget about you or mean to let you hanging, just got busy with Christmas and all. I have gone back and redone my circuit several times, adding new same size components different solar panels and still can't get the circuit to light. I found a fake car alarm on eBay that sits on dash of your car and is solar powered is off in the day and says it will blink all night, couldn't pass it up at $2.43. Going to see if I can incorporate it into the water tower as I wasn't getting any where the other way, I'll let you know what happens, Thanks Bill

    Josehf, you might get this twice as when I initially replied I just replied on the email and didn't open the link so I'm sending again. Congratulations, Gail and I just celebrated our 48th, time flies when your having fun. The flicker is only happens once and only when solar panels are in the dark and you disconnect the + battery wire and reconnect it. It's very faint and only blinks once. Think I will make a new solar panel and try that as I have replaced all the other components. Might have to purchase some kind of kit, or resolve my self to non blinking light at the top of the water tower, thanks, Bill

    new observation: when solar panel is in the light and the red wire from the battery is disconnected from the breadboard and plugged back in nothing happens, but when the solar panel is in the dark and the same operation is preformed the LED flashes a very faint single flash, don't know if that helps or not. I have tried several different LED's with the same results, Bill

All conversations after the arrow one are void due to a error on my part, sorry. the only deviance from you schematic is the 20 ohm resistor as apposed to the 100 ohm on show on your diagram as suggested by you, although I have test the circuit with both with same results. Sure I have something out of place and realize it is hard to see from pictures, so if you wish to stop this conversation I will fully understand, Bill

    They are S8550 and under that is C-F37, like I said before it tests as a PHP and will work the same in the circuit no matter to the orientation, perhaps I need to increase the resistor that was in the circuit @ 100 ohms but was dropped down to 20 ohms as per your suggestion, Bill

    also noticed that even though backwards on/off it is very sensitive, as in day light but not direct ( sun not shinning directly on solar panels) it wont light but as soon as it is placed in the direct sun beam it lights, Bill

    when I ordered the transistor from Mouser I ordered mouser # 512-ss8550cbu and mfg # ss8550cbu and according to invoice that is what they sent, I also checked with a ohm meter and it tested as a PNP, did notice though when it is in the sun light and blinking it is drawing current as if I remove 1 battery it goes out. I will test the transistor again and forward results on to you, Thanks, Bill

    Well I have retested the transistor and placing the - lead of my meter on the center probe (base) I get a ohm reading to either the emitter or the collector with the + lead, also placed a second transistor in place of the original and get same results blinking while in the sun and off when out of the sun. I also reversed the transistor and placed the emitter where the collector was and the collector where the emitter was leaving the base in it's original location, and it works the same way as the other blinking in the sun light should have the correct resistor Monday and I will retest again and but the transistor back the way it should be, Bill

    Well that could be the problem as it is green, blue, ORANGE, guess I just wasn't careful when I ordered, going to go through my small collection and see what I can find other wise I'll have to reorder, sharp eye you have there. Did recheck my solar panels and the are ok and can't detect or see any diodes and will converse after I get the correct resistor, thanks again, Bill

    Well didn't have the correct value resistor but did order some, tried to locate some that perhaps added together in series would add up to 5.6K but the closest I could get was 5.0K so I put it in to no avail and at the same time I rechecked my connections and found a loose one on the - side of the diode and by making it a good connection the LED came on a flashes only problem is it flashes during light and is off in the dark, have I got something backwards? or is it just because the value of the base resistor is quite right, Bill

    I see the error in my way, but changing had no effect but if a take a wire from the green-area and touch It to the - site of the LED the LED lights. Where I replaced the 100 ohm resistor with 2, 10 ohm in series to achieve 20 ohms, would that have any effect on it, should I try different resistors or may be none? tomorrow I will try allover again thinking maybe I have a poor connection in the breadboard and if I don't hear from you at that time I will try the 100 ohm resistor spot with different configurations. Weather has, like a lot of places been bad here with no sun light and rain but guess that's a lot better than the fires the California people are going thru, thanks again for your time, Bill

I have also ohm out the transistor and it seems to be ok, perhaps you can find some error in my wiring, Red left goes to + of solar panel, green right goes to - of solar panel, white right goes to + of battery & yellow right goes to - of battery, and still no function of led, I can jump the - side of the led to grd and it works, Thanks, Bill

    I have tried my new circuit to no positive results, the solar panel lights the LED, the battery pack lights the LED, I have tested the new components and they check ok, I have checked the new transistors and the test Ok so other than I didn't have a 20ohn resistor to place in where the diagram shows a 100 ohm one ( as you said I probably didn't need one) I left it out, so right now I'm at a loss. I have learned from testing how to determine whether a transistor is a npn or a pnp and the ones I have are pnp, so any suggestions would be welcome, and I have been using jumper wires to hook up as I didn't have a bread board and have hook them up from scratch 4 times.

    Just some updated observations, I have another same circuit that the only thing that I have done to it is to remover the converter and jumping the converter spot with a wire and it works fine, no back feed. If I was the take the problem child and hook it up to one solar cell instead of two would it still charge 2 batteries?, or another choice add a resister to the solar cells to limit out put, your thought on these ideas, my thinking is that the increase voltage is over powering a devise, probably a diode, and causing a back feed, Thanks again, Bill

Thanks Bill

    I will but before I put it out side and it got caught in the dew it was doing the same thing but I will think positive, Thanks Bill... amazing how much better the web sit works since I was able to sign up

    well there was a converter but it was out side that and I removed it and placed a wire in its place, the LED wont blink with a joule thief or converter as it interferes with the IC in the LED and wont blink, that's why I started this whole mess was to get rid of the non blinking problem, for some reason removing the converter and doubling the 1.2vdc voltage now allows the voltage to not only go to the batteries but also shares it with LED at the same time. maybe the voltage/current is too hi for the size of the diode that should be there but don't see. I would add a diode if I new where, Thanks Bill PS I did clean the board and still have the same results

    also noticed on your diagram that the one solar cell 3vdc is feeding 2 batteries that wouldn't be any different than 2 #1.5vdc solar cells in series feeding 2 1.2vdc batteries would it?

    No I did not I'm using a circuit out of a solar light that already has a dark detecting circuit in it, the only modification I did to the circuit was added another solar panel in series and added an extra battery so I would have 2.4+vdc after removing the converter or joule thief , and jumping the circuit. Dark detector seems to be working but while in the charge mode the led is pulling power from the solar panel and lighting, Bill

    New but pertaining ?, if I'm not driving you crazy, as you know I took the converter out of the circuit be cause it was interfering with the IC in the led causing it not to blink and I believe a converter is just a miniature transformer. My way of thinking is if current tried to pass backwards threw it then it should act as a resistor. Thinking maybe I should replace it with a diode or a resistor, Thoughts, thanks Bill

    I understand what you are saying but I have a circuit that is doing that now and is weather proof and very simple, there has to be something that is allowing the solar panels to feed the LED during the day, and I think it is because I removed the joule thief/ converter, and I did that because it interfered with the IC in the LED causing it not to blink, not sure if the transistor would also interfere. There has got to be someway to block voltage from the solar panel to the led? Other than building a hole new circuit is there a item in can put in the circuit, town I'm in is small and the closest place that would have electronic components is 55 miles away, Thanks for your time, Bill
