What Tools And Supplies Will You Need To Complete Hobby Electronics Projects?


DIY electronics is a world of fun. Making your own instruments, security devices, sensor equipment, or guitar pedal – to name just a fractional set of available project types – is immensely enjoyable and genuinely helps you understand the theory behind electronics. This article covers some of the essential equipment that you will need to buy or borrow before cracking on with your first circuit-building adventure.

A Soldering Iron

A good soldering iron is perhaps the most essential tool in any hobbyist electrical adventurer’s box. They are very easy to get hold of and can be purchased wherever you get your electronic components online. The concept behind a soldering iron is simple. Electrical current needs to flow through a conductor in order to complete a circuit. This means that anything used to secure components into a circuit must be conductive. Solder is a highly conductive metal adhesive that melts easily and solidifies quickly. Soldering irons heat up enough to melt solder. They are used for soldering components together by applying molten solder to connections. They should be used with great care to avoid burns. Soldering irons are powered by mains electricity or gas. A mains electricity powered iron is recommended for beginners.

Crocodile Clips

Soldering is the ideal way of adding components to a circuit, but solder is rather awkward if you plan on testing lots of different combinations before finalizing a circuit design. Crocodile clips allow you to experiment. They are essentially spring-loaded, conductive clamps usually attached to a small length of wire. Often known as ‘test wires’, they can be easily attached and detached to test the feasibility of a design. Packs of crocodile clips with and without wire are relatively cheap from electronics retailers.


Multimeters measure voltage, current, resistance, and occasionally other values. They are useful for troubleshooting any issues with your circuits and for establishing the power output of any batteries you are using. Most hobbyists will use a multimeter extensively when testing how compatible their components are and how efficient their circuits are. A multimeter is especially useful when you are confronted with a seemingly complex issue with a circuit. They allow you to run through a checklist of possible issues, eliminating the ones that are proven to be nonexistent.

Wire Stripper

Working with wire can prove rather fiddly. One of the most frustrating tasks tends to be trying to neatly reveal a strip of conductive copper from the insulating rubber surrounding a wire. This can be made markedly more simple by using the correct tools. A good pair of wire strippers easily remove insulation without damaging the wire itself.

Hot Glue Gun

A hot glue gun is invaluable for the electronics hobbyist. You can secure components in place, tidy up loose wires, and generally make everything more permanent without fiddling with superglue. Hot glue guns are cheap as chips and really help you put the finishing touches on any project that you are working on.
