Newb here and just wanted to chime in on my first EL-Wire experience. I wanted to build a cool blink/light system for my bike and decided to go with a variable sequencer and 7-10 strands of EL-Wire. After lots of search and solo deliberation I went for equipment from http://www.coolight.com/
. Now I'm in no way affiliated with these guys but I wanted to come here and say how helpful they have been in assisting me with some issues on my first endeavor. First, I received all parts in super quick fashion and set to work soldering, shrinking, and blinking. About 2 weeks after getting all the stuff I was ready (last night, I'm a super slow solderer) to fire up the 10 channel sequencer and test my creation... however I was only using a 9v battery as the stated input voltage for the sequencer was 9v-12v.
Well, the sequencer did a few bursts but only on a quarter of the channels lit up and it didn't seem to be responding to my changes to the inputs as expected (strobe rate, pattern, delay). I called Coolight (after the close of their business day) and left a message asking for some assistance or possibly a replacement as my sequencer didn't seem to work correctly. Unexpectedly, (and awesomely) I got a call back within a couple hours from Joel who was very patient as I explained my idea/design, and what I was experiencing. He figured I might have a bad unit and told me he'd build a fresh one that night and run a full battery of tests with similar wire lengths to what i was using and ship it out the following day. GREAT! Well, Joel went above and beyond and called back again later after he built a new sequencer and did some testing with different voltage inputs, low and behold (I'm pretty new to electronics so I didn't even think about this) a 9v battery generally doesn't output 9v and unless using a wall-wart which delivers the stated output voltage a single 9v wouldn't provide the needed juice to cleanly power the circuitry in this unit. He explained some other battery options (12v seems to be the way to go) and I actually had a 12v cage (made up of 8 - 1.5v AA batteries) but only a few fresh AA's in the house so I swapped that battery pack in and tried another go. This time the sequencer fired off the expected pattern(s) twice before acting a bit odd, but this I now understand is due to having less then fresh (and some fresh) batteries in the cage. Joel went on to explain how he got the unit to work by splitting the inverter off the main battery input to use a separate battery while still using the standard 9v-12v input for the EL-Wire, great thinking! He also noted that a daisy chained (2x 9v) housing would probably work.
Today I'm thinking of what might be more cost effective or allow a rechargeable option and have come across some rechargeable 12v batteries on Amazon (UPG D5779 UB1280-F2 Universal Lead Acid Battery) and am trying to figure out (before purchase) if this might provide the needed power. I could buy a couple of these and a wall charger and (hopefully) power my bike light system for the 5 nights I'll be on playa... what do you think?
I know this is a bit long, but does anyone have any experience with quality (>5 aH) 12V rechargeable batteries? And lastly, thanks again to Joel and the www.coolight.com
folks (who it turns out are long time burners) who have provided some guidance and of course the needed equipment to get me this far!
Cheers all- keep spinning!
