DIY projects are exciting and fun. Building electronics yourself is a good way to learn, practice and improve your skills with machines. It is always fascinating to watch people create things using science. The following are some of the best DIY electronics that you will find interesting. DIY electronics offers alternative ways of doing things other than using the existing tools and machinery,  just like the case of VPN vs Cloud.

Water Batteries

Creating batteries out of water is a fun way to learn chemistry. This simple project requires simple and easily accessible materials such as water, plastic bottles, and clamp cables. Among other resources needed for this project include copper, zinc, low voltage of led lights and copper sulfate. This experiment works on the concept of creating electricity from the variation of salt present in water. Freshwater which charges the battery is exchanged with salty water that contains more ions and as a result, the battery discharges due to the rise in electrical potential and hence producing electricity. This means of generating electricity is cheap and effective.

Emergency light from fire and water

This gadget comes in handy when having a power shortage or in a place without electricity access. Building this device is also a good way for students to learn and understand science and all its wonders. Creating emergency light requires a few accessible items such as food items and electronic gear. The idea in this project is to generate electricity from temperature difference. A thermoelectric module with one side cold and the other hot is used. The heat from the hot side moves to the cold side with the aid of an electric load hence producing electricity.

Bicycle powered generator

With this DIY project, you can easily produce enough electricity to power your electronics. You will need a bicycle stand and frame, a car battery, DC-AC inverter, Fan belt, DC-DC battery charger, wires and 24V DC scooter motor. Basically, the back wheel on the bicycle frame rotates the DC motor through the fan belt.  The motor is linked to the charger controller which is connected to the lead-acid battery. The controller, therefore, charges the battery and gives power. Plug your electronic device to the inverter connected to the battery to access power.

Portable solar phone charger

This is a cheap and efficient way to charge your phone especially when having power shortage. You will need a 6V mini solar panel, a dismantled USB charger circuit, wires and your phone.  Take the charger circuit and fuse it to the solar panel ensuring that the USB port does not protrude.

In conclusion, DIY electronics can make great survival kits as well as cost-effective ways to get work done. Safety precautions should, however, be observed to minimize accidents and injuries.
