DIY IR (Infrared) Illuminator - Night Viewing With Your Camera

Step 2 Installing The First 8 LEDs

The simplest way to begin the install is to insert and solder into the board the inner row of LEDs. These are located at D3, D6, D8, D12, D14, D17, D19 and D22. Keep in mind that LEDs are polarity sensitive, so ensure that you line up the flat on the LED with the flat on the solder mask on the board. After you have soldered in the first 8 LEDs, trim the leads.
