1 Intro The Enecsys Gateway is a Zigbee gateway allowing communications between the Enecsys microinverters and their monitoring backend. The Enecsys company is unfortunately defunct since 2015 and their DNS domains have been taken over by a UK enecsys...
What is bio-engineering?Bioengineering is the application of engineering and science principles to tissues, cells and molecules.What can you do with the bio-engineering basic kit?The kit contains two main items: An Arduino Mega shield with 3-D printed...
As usual, the problem isn't a new problem, and this isn't a new solution. But I will describe it to help someone doing the same. With this project I've made a wifi infra-red remote control for my Daikin air conditioner. In these schema you can see...
A screw-propelled vehicle is a type of land or amphibious vehicle that uses one or more auger-like cylinders fitted with a helical flange to move. The cylinders are rotated by an engine, and the flange engages with the ground or water to propel the vehicle...
Here is the compounds i made my element collection from: 1.Hydrogen: From HCL3.Lithium: Li-Ion battery from old battery.5.Boron: Neodmyum Magnet (You can find 2 small magnet in your PC CD/DVD.. writers laser head)8.Oxygen: Cerium dioxide lighter flints...
Cornell University Electrical and Computer Engineering 4760 AVR mega644/1284 Mixing assembler with GCC IntroductionIt is possible to mix assembler and GCC in different ways: Separate file. Write a pure assembler *.S file and link it with the main C file....
The work by others to port Arduino BASIC to the Smart Response-XE device was of interest, but I wanted a few enhancements to extend battery life (auto shutdown) and I wanted an easier way to do math on the console rather than typing "PRINT" everytime...
IntroductionI've owned a MicroKim by BrielComputers for years, but it had been defective for a long time: as it turned out, the EPROM was malfunctioning. This project describes how I found out what the problem was, and how I fixed it. And hopefully it...
At that moment in time, the "Hobby" computer was cut of the edge technology:- compatible with both of the major Z80 operating systems of the time: CP/M and ZX Spectrum- single (256 x 192) and double (512 x 192) screen resolution- hardware switchable...

Turing Machines 101 The Turing machine was invented in 1936 by Alan Turing. By providing a mathematical description of a very simple device capable of arbitrary computations, he was able to prove the properties of computation in general. A...
Wheel of The Year On 16 segment Display The wheel of the year is divided in 8 intervals, and the corresponding segment is lit whenever the current day is inside the interval. In the picture below, the segment will be lit from February 1st until March...
Ok, first of all an important mention goes out to Edderic Ugaddan (twitter @eddericu ) who is currently making and selling a cool device called the Laminair. It's his research that showed me that this kind of device was valuable, because he has...
Another clock? There is nothing particularly special about this clock, except perhaps that is is built from a 8042 microcontroller chip (henceforth MCU) salvaged from a very old PC. The most modern component is the integrated serial display which...
