Tesla will be carrying out this project along with the French company Neoen, a company which is specialized in renewable … Continue reading

Smartphone based on Raspberry Pi Zero

There are many attempts to build an open source phones. This is possible with availability of required modules like GSM, Wifi and other parts. All you need is to put hardware together and take care of software. Of course it sounds easy and fun, but in reality you may face lots of problems starting with selecting components, assembling them in compact shape, writing code. Be sure the end result always be a brick in a hand. Anyway building a phone can be fun and give valuable experience. Arsenijs have shared his interesting smartphone solution in hackaday.io. He used Raspberry Pi zero as base component. He wanted phone to be repairable, cheap and built from available parts. The end declared price is about $50.

Geocache box with extra challenge

Yes, geocaching is still live and people enjoy this activity. GPS (or other) accessible to anyone who have at least a smart-phone. The idea is simple – you need to find a cache according to GPS coordinates. Usually this is hidden storage box with log book with sometimes additional treat. In order to make things more challenging, Cliptwings constructed a puzzle box powered by Arduino. The puzzle is a hangman game which has to be played and won in order to open the box. Controls are pretty simple – by turning knob you can select a letter and with single button you enter it.

Opening garage door with fingerprint

There are still majority garages that can be opened with regular key. This is probably least secure way of protecting property – especially with standard locks. As you may know, most of standard locks can be picked in a minute. In order to be more safe, better install more secure lock with sophisticated key or go with electronic based system. Joebarteam have shared his instructable, where he built a fingerprint lock system for his garage. The basics of electronics is built around Arduino micro which reads electronic finger print scanner through serial interface. A bunch of limit switches ensure that closed, opened rood is detected correctly, also there are few fail-safe mechanism implemented that makes system power efficient and even safer. Mechanical lock is moved with stepper motor and seems … Continue reading
