What are some cool gadgets (under $200)


Recommended Posts

Recently bought some 10 x 42 binoculars to have a little gaze around my neighbourhood and I already have a multimeter to test out voltage in my house and in batteries. What are some other fun not to pricey gadgets that are fun to have around? I was also thinking of getting some night vision goggles...

  ..the next step should be perhaps digital oscilloscope?

Endoscope for smartphone? ($10-$20 or so)

If you found multimeter "a fun little gadget to play with", then maybe Arduino?

Default introductory kit should keep you busy for a month or two.

e.g. get Bluetooth transmitter *) for Arduino, get water pump (in e.g. pet shop, pump for fishes), and build device for remote (by smartphone) control irrigation of indoor plants in pots. Make simple single button on/off Android app, which will connect to BT device and control water pump on demand. *) requires 5V <-> 2.5 V power/signal converter.

Perhaps LCD microscope?
