Where would we be without the crazy inventions that make life interesting? It's even better when they're actually useful as well. So what if you already have a head torch and a pair of earphones? A beanie that literally empowers you with sight and sound takes awesome to the next level, whether you're out in the wilderness or just walking home from the station at night.

Check out this ingenious gadget, plus four others that might not be necessary for survival, but put a brilliant new twist on getting a kick out of technology every day.

Bluetooth® Beanie with LED Torch & Headphones

This Bluetooth® beanie does a lot more than just keep your brain at a comfortable temperature. With a built-in LED torch and integrated headphones offering 10 hours of listening on a full charge, it puts a whole new spin on 'smart casualwear'. The battery recharges via USB and the electronics are easily removable on laundry day.

  • 10-hour battery life — plenty of juice for long hikes or late-night commutes
  • Built-in LED torch — hands-free illumination without a separate headlamp
  • Removable electronics — toss the beanie in the wash without a second thought
  • USB recharging — top up from any power bank or laptop port
Jaycar tip: Perfect for early morning runs or evening dog walks — pair it with your phone playlist and you won't need to carry anything extra.

Spring-Loaded Fly Pistol

Spring-loaded fly pistol gadget for pest control at barbecues

Keep this spring-loaded fly pistol on hand for your next barbie and you'll have a chemical-free licence to deal with annoying airborne pests. It's a lot more fun than a flyswatter!

  • Chemical-free — no sprays, no smell, no mess on the food table
  • Satisfying to use — turns pest control into a bit of a competitive sport
  • Compact design — easy to keep handy in a kitchen drawer or on the patio
Jaycar tip: Great as a novelty gift — it consistently gets passed around at gatherings once people spot it.

Ultrasonic Cleaner

Ultrasonic cleaner with jewellery and watch strap inside the cleaning tank

An ultrasonic cleaner is one of those appliances that sounds a bit 'out there' until you realise how many things it's good for. Never again will you have to tolerate annoying little deposits of grime in a metal watch strap, or spend hours trying to get ornate jewellery sparkling again with an old toothbrush. Just add water and mild detergent, pop in your item and set the cleaning cycle.

  • Works on jewellery — reaches into crevices no brush can touch
  • Great for watch straps — clears accumulated grime from metal links
  • Simple to operate — fill, load, press go
  • Chemical-light cleaning — mild detergent is all that's needed
Jaycar tip: Also works brilliantly on small electronic components, coins, and glasses frames — once you own one, you'll find new uses for it constantly.

USB-Powered RGB Message Fan

Deal with warm weather in the coolest way possible thanks to a USB-powered fan that uses RGB LEDs and the persistence of vision to display a message of your choice, up to 10 photos, or the time and temperature. It connects to your phone via Bluetooth® using a free app.

  • Custom messages — display text, images, time, or temperature as the blades spin
  • RGB LEDs — persistence of vision creates vivid, eye-catching visuals
  • App-controlled — pair via Bluetooth® and update content from your phone
  • USB powered — plug in to any USB port or power bank
Jaycar tip: A brilliant desk piece for an office or gaming setup — programme it with your Wi-Fi password for guests.
