| + | {{bloc-etroit|text=A single 1N4001 diode has about a 0.7 Volt drop across its leads. Wired to our 6 Volt battery pack (when using alkaline cells), this yields 5.3 Volts output. That’s within our 5V±10% target window, so this simple component addition is all that’s needed to use the battery pack with the LED strips and pixels. |
| + | |
| + | This same solution can be seen in our Digital Programmable LED Belt Kit. |
| + | |
| + | Diodes have a specific polarity, passing current in only one direction…the silver stripe is the + end. So we want to connect the + terminal from the battery pack to the “dark” end with no stripe.}} |
| + | |
| + | {{ambox-stop|text=This sequence is only needed if you’ll be using alkaline cells. If you know for a FACT that ONLY rechargeables will be used, this part can be skipped. If you’re unsure, or will use different cells at different times, add the diode.}} |

| + | == Montage == |
| + | |
| + | {{asm-begin}} |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-10.jpg}} |
| + | {{asm-text}} Cut the '''rouge''' wire of the battery pack short by about an inch. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-11.jpg}} |
| + | {{asm-text}} Strip off about 3/8" insulation from the red wire. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-12.jpg}} |
| + | {{asm-text}} Then “tin” the end of the wire with a bit of solder to keep it from fraying. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-13.jpg}} |
| + | {{asm-text}} Clip the end of the diode (the “dark” end, without a silver stripe) to a similar length, then solder the red wire to this. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-14.jpg}} |
| + | {{asm-text}} Clip the other end of the diode (the side with a silver stripe). |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-15.jpg}} |
| + | {{asm-text}} Cut off and slide a 2" piece of heat shrink tube onto the red wire. Keep sliding it all the way past the diode. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-16.jpg}} |
| + | {{asm-text}} Now solder the positive wire from your LED circuit to the “stripe” end of the diode. Or you can add a plug/receptacle pair between the two to make them easier to separate and service later on. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-17.jpg}} |
| + | {{asm-text}} Take the piece of heat shrink you slid over the wire before… |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-18.jpg}} |
| + | {{asm-text}} …and slide it back over the diode and the solder joints. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-19.jpg}} |
| + | {{asm-text}} Shrink the tubing to grip the diode and wires. You can use a heat gun, lighter or the edge of your soldering iron. |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-20.jpg}} |
| + | {{asm-text}} Taa-daah! |
| + | |
| + | {{asm-end}} |
| + | |
| + | The black wire from the battery holder then connects to the ground wire of the LED circuit (or plug/receptacle, if you’ve installed one). This side is much simpler than the diode-equipped wire: |
| + | |
| + | {{asm-begin}} |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-30.jpg}} |
| + | {{asm-text}} Slide a small 1" piece of heat shrink onto the black wire (this image shows a much shorter piece…oops…go a little longer than this). |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-31.jpg}} |
| + | {{asm-text}} Solder together the ends of the wires. The dreaded inline splice! |
| + | |
| + | {{asm-row|img=Alim-Pixel-Accu-Pile-Diode-32.jpg}} |
| + | {{asm-text}} Then slide and shrink as you did before. Done! |
| + | |
| + | {{asm-end}} |
