While browsing for construction ideas, I stumbled upon a construction by guys from MikroElectronika: https://www.hackster.io/16283/esp8266-mikroe-buggy-ccd102
So I put out an old metal construction kit I inherited from my father and built a "car" chassis. You can see the result under the original project, in Replications section.
What I like about this construction (I mean the DIY variant, not buying the original kit):
- easy to build (ca 1 - 2 hours including build the chassis)
- cheap electronics - ca $10 for the parts, not including power source - my power bank was a giveaway (previously I used 4x NiMH AA battery and a battery holder)
- cheap chassis - could be made from metal, wood, plastic, maybe even hard paper
- cheap remote control - I assume almost everyone has a cell phone / tablet with WiFi and HTML5 capable browser
- easy to expand - remote control software, micro-controller firmware, the hardware - more wheels, sensors, etc.
- doesn't rely on 3rd party cloud services, registrations, ...
(More images are on the original project page.)
What do you think?
