system configuration once the sensors from the garden are connected to the v2 controller board, we are ready for system configuration. we will configure host names, time zones and wifi. at which point the raw data from the sensors should be ready for remote visualization through the api. configuring a unique garden name on the […]

aquaponics uses bacteria to break down fish waste to grow plants without soil in a recirculating water system. smart aquaquaponics allows you to use your computer or mobile devices to visualize and control your aquaponics garden remotely. a typical garden is shown below: in this post we will looking at required material lists, how to […]

Sensor types: V2 smart controllers support different sensors including digital sensors(eg a float switch), analogue sensors(eg photocell),  1-wire sensor(temperature), i2c, serial and usb based sensors The v2 board can interface most of  these directly without any extra external circuitry. Connecting digital sensors connecting digital sensors to v2 controllers using internal software based pull-up resistors is […]

i love flowers .. all shapes, all sizes, all colors … above all(most) scents. sometimes it is the only thing i grow … in my shamba. coming to  thinking about it, i think i choose a science pathway because of flowers, but that is a story for another day. i remembered this when i saw […]

i had multiple milestones yesterday. some enormous ones lost me in the future. in the numbness of the present, all i could think about was teachers that taught and helped me learn. i think i was escaping reality, redirecting my mind from the fact that i received a shipment full of v2 boards sitting on […]

the last two weeks of the year normally sets the trends for my next year. my new year generally starts just before xmas which means my focus is renewed and runs deep during the holidaze. this results in numerous all nighters and traditionally i have always designed something new and picked up a new technical […]

Kijani Grows is an aquaponics company so one may expect to learn aquaponics farming through an internship with them. However, though the success of the farms is the ultimate goal of the work, you will actually learn or draw upon a breadth of knowledge that goes far beyond farming. A lot must be done to […]

we ran into production related challenges and had to reconsider numerous scenarios. we pivoted some and our new v2 smart controllers boards are just about ready. v2 comes with inbuilt linux microcomputer controlling an atmega2560 microcontroller, 20+ digital sensors, 10 analogue, 3 uarts, i2c, 12 relay controls, wifi, eth, mini sd-card, usb(video, audio, cellular), watchdogs, […]

shellshock is frightening. it does not affect any of the current releases.

Our smart controllers were running a version of openssl that was affected by the heartbleed bug consider ‘the biggest security vulnerability of all time’ as an attacker can remotely connect and steal encryption keys or data from processes in memory. Our production and development servers were not affected as they run older versions of openssl. […]
