Long, Narrow Solar Panels

-

hi there,

i'm looking build solar-powered sign led's solar panels long , narrow (less 1" wide). need total solar panel length of 20-24 inches other size considered. found thin solar cells like this they're 1.5" wide, bit wide me.

also, what's way attach these solar panels, if don't have adhesive backing? there type of glue can used that? think products solar powered garden lights route wire inside of enclosure under solar panel , epoxy wire waterproof it, how attach panel surface?

to summarize, here specs need:
- less 1" wide preferably
- @ least 12" long, 22" ok
- i'd rather not have put multiple cells in parallel. i'm thinking need 4.5-6v.
- i'm driving bunch of rgb led's, 50 of them when gets dark outside. wonder if that's possible because draw 20ma on average, that's heck of lot of power 1w or less solar panel
- what's best battery use? thinking standard 3.7v lipo batteries i'm considering ni-mh or ni-cd batteries. however, heard ni-mh have bad discharge drainage.
- need attach solar panel in way that's waterproof

let me know if have ideas, thanks!

you need calculate power use , plan solar panel/battery storage accordingly. example, 50 3.2v leds @ 20 ma each consume 3.2 watts.

lipo batteries extremely problematic , destroyed in first charge/discharge cycle, if not follow rules carefully. need special circuitry both charge , discharge control.

hello  guy, trying flash firmware on arduino uno rev3 atmega 16u2 using atmel flip. whenever try , import .hex file program, throws error " address out of range ." have looked around online , haven't found solution. , info helpful. here hex file : https://github.com/nicohood/hoodloader2/blob/master/avr/bootloaders/hexfiles/hoodloader2_0_5_uno_atmega16u2.hex its using arduino uno hid Arduino Forum > Using Arduino > Installation & Troubleshooting > Flip address is out of range arduino uno r3 arduino

Arduino Uno not uploading

hi guys, so, have arduino uno r3 (not wired thing) when try upload sketch (even empty sketch) first takes long in "uploading..." comes error: arduino: 1.8.0 (windows 10), board: "arduino/genuino uno" sketch uses 444 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x9f avrdude...

Indesign and MathType fonts

-
i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
