Step 5The final few
Now is the big moment for your circuit: find the little piece of silicon with three leads and a metal tag. This semiconductor is what powers the whole circuit. (no pun intended) Look at the image below for notes on setup.
Once you have the regulator set up as shown, it's time to stick it in the circuit. It's fairly easy to guess where it goes, but if you aren't in the mood for 20 questions, it should be placed with the label away from the edge of the board. Once again, consult the pictures below to see the placement of the regulator. Solder it down. You might have to slightly bend the resistor out of the way to get it in there, but if you need to bend anything else, that probably isn't a great sign....
Okay, you now only have a few parts left that you got in the kit, right? Well, of those parts, there should be a 470 ohm resistor, which in case you didn't know is marked with a yellow, violet, and then a brown stripe, plus a gold one for tolerance. This resistor goes from I16 to A16. Solder it down and trim off the excess.
Next up is the little green LED. If you look at the two leads, one should be shorter than the other one. That lead is the negative one. With that in mind, stick the LED in the circuit board with the negative lead in B14. The other lead goes in A14. For optimum photon emission rates, have the very top of the LED about 1/2 to 3/4 inches from the circuit board. Once you have it placed, solder it down.
After that, there are the terminal blocks to place. One of them goes in the far bottom left corner of the board with the "G" of Gadget Gangster upside down. If you want specific points, one of the two leads goes at 1, while the other goes in Q3. Solder that block down with the actual terminal openings facing away from the very edge of the board, pointing towards the empty section of the PCB. Directly across from the terminal block you just soldered, place another terminal block. As shown in the picture, the terminals should mirror eachother: both facing in and on the far edges of their respective sides. If you didn't understand any part of what I just said, then place a second terminal block facing inwards with one of the leads at A1 and the other lead at A3. Solder it.
You're almost there! Only a few more things to solder down! Alas, there are two jumper wires that seemed to slip my mind while placing all the others. They should both be a sort of bluish color. One of them goes from I2 to F7, while the other wire goes from L7 to I12. Both of them need to be on the back of the circuit board. Once those are down, consult the picture to ensure that your PCB looks just like the one shown.
One final part! The last part should be a third terminal block. this one goes at H7 and J7 with the openings facing away from the rest of the circuit. Solder it down and give yourself a pat on the back, because you're done! the image notes give info on which terminal is which. Also, the potentiometer changes the output voltage. When the potentiometer is turned so the small flat part on the clear section is facing the voltage regulator, the LED power light is off, but a bit of voltage still goes through. If you have a multimeter, you can just play around with this for a bit to see what output voltage you get at certain points of rotation of the potentiometer. This has endless applications, so it is a very handy thing to have around when building circuits. Good luck!
As a final note, I hope I made a satisfactory first Instructable. If you have any questions, comments, or constructive criticism, please post a comment about it.
