The laser driver is the electrical component that controls the functioning of the laser. The diode will likely need soldered to the laser driver. There should be two leads coming from the diode for this purpose. Use a soldering gun to solder the leads to the driver at the positive and negative terminals. These terminals should be labeled on the driver and extend to the edge of the driver for soldering purposes. The driver should not be connected to any power source until soldering is complete. After the diode has been connected to the driver, you can connect the driver to a power source. Batteries are the go to choice since they make your laser portable. You will need at least AA batteries to produce a burning laser. The driver will have leads for a power supply. These leads will need to be connected to a battery pack or directly to the battery. If the leads need soldered, you will have to use a battery pack. You cannot solder onto a battery. You can buy a laser casing online to house the parts of your laser. Alternatively, you can make a laser casing from things lying around your house. Popular items used to make casings include Altos mint cans, bic lighters, and the casings of weaker laser pointers.

summary: Connect the diode to a laser driver. Power the laser with batteries. Encase the laser.

Depression can make a person feel worthless, but you can use encouraging words to support your friend until your friend remembers his or her worth again. Say something encouraging to your friend every day to show that you care and that your friend is valuable to you and to others.  Point out your friend’s strengths and accomplishments to help build them up. For example, you could say, “You are such a gifted artist. I really admire your talent.” Or, “I think it is so amazing that you have raised three wonderful children on your own. Not everyone has that kind of strength.”  Give your friend hope by reminding them that the way they are feeling is only temporary. People who suffer from depression often feel like things will never get better, but you can remind them that this is not the case. Say something like, “You may not believe it now, but the way that you are feeling will change.”  Avoid saying unnecessary things like, “it’s all in your head,” or, “Snap out of it!” Making judgmental statements like these will make your friend feel worse and may cause their depression to become more severe. Depression can make people feel isolated and like no one cares. Even if you have demonstrated your concern by doing things to help your friend, he or she may need to hear you say that you are there for them in order to believe it. Let your friend know that you are available and that they should contact you right away if they need you.  You can communicate your willingness to help by saying something like, “I know you are going through a difficult time right now, and I just want you to know that I am here for you. Call or text me if you need me.” Try not to get discouraged if your friend does not respond to your positivity the way that you want or expect. It is common for people with depression to be apathetic, even towards people who care about them. Remember that sometimes the best way to communicate your support is just being there with the friend. You can just spend time with them watching a movie or reading, with no pressure to talk about depression or even to hope that they will cheer up. Accept them just as they are in that moment. Set boundaries about when you can accept phone calls or texts. No matter how much you want to help your friend, make sure that helping them does not take over your life.
