Step 4: Connect the Usb Connector

we will need only the red and black wire.
my connector had red and a blue wire.
connect the red wire to the positive terminal of the blinking circuit.
connect the black wire to the negative terminal of the blinking circuit.
Do you have to program the 555 Timer Chip?
its called an electrolytic capacitor, not electrolyte
wats kept in the spelling??/
uhg first off you dont make sense and I see this is a totally lost cause.
I like this design! it's cool to be able to make something out of with electrical components that works with a computer!<br> <br> If you like 555 timers, check out <a href="http://www.csgnetwork.com/ne555timer2calc.html">this 555 timer calculator.</a><br> <br> <br> <strong>A Few Questions:</strong><br> How much current does this thing draw?<br> Are you using a schematic program? if yes, which one?<br> <br>
it draws about 20-25 mv <br>i did not use any schematic program.<br>i used paint to draw the schematic.
If your looking for a great schematic program that is free, downlaod&nbsp;<a href="ftp://ftp.cadsoft.de/eagle/program/5.11/eagle-win-5.11.0.exe">CadSoft: EAGLE</a><br> Or go to their website:<br> <a href="http://www.cadsoft.de/download.htm">http://www.cadsoft.de/download.htm</a>
thanks for the software.
no prob
To save a considerable amount of time and expense, you do realize there are LEDs with the flash circuit built in. The USB port can support 10 or so wired in parallel, and an interesting thing, is that they all flash at slightly different rates, which makes the seem to flash randomly.<br><br>There are more self flashing options these days as well, pretty much any color, alternate between two colors, RGB flash, RGB fade, and some amber that simulate a candle.<br><br>Only make mention, as there is much better chance of success, and save some money, in these tough times.
