RGB Color Controllable High Power LED Room + Spot Lighting

Step 10 Start stuffing the circuit board

the proto-board shown does not have any of the holes wired together, so to keep things simple we'll wire vertical columns together after the components are inserted. "better" proto boards already have the columns wired together, and that makes your life a lot easier if you have one of those. so here, anything we plan to wire together we'll put in the same vertical column of holes, and that way if you already have a proto board wire wired columns your circuit will look very similar.

- you will need about a 1" x 3" piece of proto-board minimum. mine is about 1" x 4", but i have quite a lot of empty space when i'm done.

- we'll be building 3 nearly-identical circuits. the only difference will be the R1 and R2 resistors.

- start by inserting and soldering VREG and Q1 into your proto-board.

- to identify the pins on the parts, look at the labeled front of the part with legs pointing down. pin 1 is on the left, pin 2 is the middle, pin 3 is on the right. look at the pins labeled in the schematic:

VREG:
ADJ = pin 1
OUT = pin 2
IN = pin 3

Q1:
E = pin 1
B = pin 2
C = pin 3

Hi, id like to know how you cut your board. Like what tool did you use? thanks.

Looks like there's a hacksaw in that photo. That's likely what he used.
