Repairing electronics or appliances
CostMedium
Includes: Multimeter, screwdriver set, soldering tools, wire cutters, spare parts, safety gear Example: A starter toolkit runs about €50. More advanced setups with rework stations and diagnostics gear can range up to €800.
What it is
One household throws a dead toaster in the bin and buys a new one. Another opens it up, finds a blown thermal fuse worth 40 cents, and has it working again in twenty minutes. The gap between those two outcomes is mostly confidence, and confidence is exactly what this activity builds.
Repairing small electronics and appliances is part detective work, part stubbornness, and part quiet satisfaction. You open up the things most people discard, work out what failed, and bring them back. The faults are often absurdly simple once you find them: corroded battery contacts, a single frayed wire inside a headphone cable, a switch clogged with grime. A starter kit of a precision screwdriver set, a multimeter, and a basic soldering iron costs around €50 and unlocks most of it. The iFixit screwdriver sets and a budget multimeter from AstroAI or Uni-T are the usual first buys.
The real skill is knowing when something is worth fixing. A rough rule that works: if the repair costs less than half the price of replacing the item, fix it. Sentimental value tears that rule up, of course. A grandfather's radio is worth restoring at any price. Most people who get into this find the satisfaction outlasts the money saved. There is a specific click when a button drops back into place and the thing powers on, and after the third or fourth repair you start eyeing every broken object in the house as a puzzle rather than rubbish.
How it works
Beginners almost always reassemble before they remember how it came apart, then spend an hour staring at three leftover screws. Photograph every stage as you go, especially connector orientation and which screw came from which hole, because manufacturers love using four slightly different lengths that only fit their own spot. Your phone is the most useful repair tool you own.
Choose a low-stakes patient first. A flashlight that will not turn on, a speaker that crackles, a remote with a dead button. Open it carefully and become a detective rather than an engineer. Are the battery contacts green with corrosion? Is a wire loose at a solder joint? Does anything smell burnt or look bulged, like a swollen capacitor? Most faults are this visible once you actually look. A multimeter set to continuity confirms whether a switch or a cable is broken, and a budget Uni-T or AstroAI meter does this perfectly for under €30.
The decision of whether to bother repairing is its own skill. A rough rule that holds up: if parts plus your time cost less than half the price of replacing the thing, fix it. Common parts are cheap, replacement screens at €15 to €60, batteries at €5 to €30, so the maths usually favours the repair. Sentimental items break the rule entirely and are worth fixing at any price. When you do solder, heat the joint and feed solder into it rather than dabbing molten solder off the iron, which only ever makes a weak, dull connection that fails again later.

FAQs
A precision screwdriver set, a multimeter, and a pair of spudgers or plastic prying tools. iFixit sells a screwdriver kit with Philips, flathead, and Torx bits that covers almost every device you will open. A budget multimeter from AstroAI or Uni-T (around €25) lets you check continuity, voltage, and whether a fuse has blown. Add a soldering iron only when you reach a repair that needs one.
Compare the cost of the part to the cost of replacing the whole device, then add your time. A €4 capacitor in a €200 monitor is an easy yes. A cracked logic board in a five-year-old laptop usually is not. Search the model number plus the symptom first, because most common faults are already documented with photos and the exact part needed.
It can be, so respect a few rules. Unplug everything and wait before you touch it. Anything with a large capacitor (microwaves, CRT televisions, power supplies) can hold a lethal charge long after the plug is out, so leave those alone until you have learned to discharge them safely. Low-voltage battery gadgets like phones and headphones are far more forgiving to practise on.
For common consumer devices, iFixit, AliExpress, and dedicated spares sites cover most needs. Search the exact part number printed on the failed component rather than a generic description. For appliances, the manufacturer's own spares portal often stocks things like door seals and heating elements. Take a clear photo before you remove anything, because matching the old part by sight saves a lot of returns.
Probably one or two, and that is normal. Start on dead devices you were going to throw out anyway, since there is no pressure and no loss. The skill that separates a good repairer from a frustrated one is patience: working slowly, keeping screws organised, and not forcing anything that resists. You learn the feel of how things come apart by taking apart things that no longer matter.
⚠️ Capacitors in microwaves, old televisions, and power supplies can store a dangerous charge even when unplugged. Do not open these until you understand how to discharge them safely.
