Farmbot rises farming to next level

Growing your desired greens is pretty intense work. The preparation of soil seeding planning and constant care must be done to get result. It may seem that there isn’t much to do – just plant a seed and take a look from time to time. But in reality, growing great looking, nutritious plants require constant care that include watering, weeding, fertilizing and timely collecting. If farming isn’t your primary job, then most likely you are going to forget to water or pick weeds. This is why Rory Aronson decided to develop open source farming machine. Farmbot is a 3 axis CNC platform that can vary in size depending on your soil area. It is capable of taking care of multiple different kinds of crops in same area. Planning and taking care of garden is done via web based interface – its like one of those farming simulators, the only difference is the time you need to wait between some actions and the result is real. Farm bot can work with different tools like seed injectors, watering nozzles, sensors, weeders. All… Continue reading

Expanding Raspberry Pi 3 WiFI range with external antenna

With appearance of Raspberry Pi 3 the new wave of hacking begun. This time the attention falls on new WiFi functionality. As wardr states: “It’s not clear why an external antenna is not an option for the Pi 3 ”. Having said that he thought why not including one by himself. He found that there can be two options of including external WiFi antenna. One could be more barbarian – just remove chip antenna and solder it to left top mount pad. This is more messy part as you need to scratch ground plane to make it possible soldering copper mesh. Another way is more civilized. On the bottom side of Raspberry Pi 3 there is two exposed pads where U.FL connector almost fits. Yet you still need to clear some solder-mask and rotate one zero ohm resistor. By attaching external antenna he was able to get better results. Continue reading
