Aquaponics System Build

550L Aquaponics system

550L Aquaponics system

A couple of months ago Dennis presented a course on building a desktop aquaponics course which was a demonstrator of the technology that turns fish food into organic vegetables and fresh fish.

Dennis was also featured on Let’s Talk Hack where he went into how Black Soldier Flies supplements an aquaponics system, to use kitchen waste as the food source for the fish!  This adds a very interesting dimension, reducing total waste for a household.

Saturday, Dennis presented a course and system build on a large scale aquaponics system – the course consisted of a theory portion and then a build.

Squiggles : a quadruped with attitude


Philip brought along his 3D printed Mini Quadroped ( to H4H on Tuesday – it runs on 4x 1.2V NiMH batteries and can autonomously roam the room using ultra-sonic range sensors to avoid collisions.  It uses eight servos controlled by an Arduino Nano, so each leg has two axes of movement (2-DoF)!

Ok, so I had to look it up: “Quadrupedalism is a form of terrestrial locomotion in animals using four limbs or legs.”
