New method for measuring lots of resistors using very few wires – part 3 – a simple measurement device
The hardware implementation The previous bits of the article ( part 1 and part 2 ) described the core concepts of this measurement and the theory behind it. The actual measurement device – the measurement system is pretty simple when … Continue reading
The Matrix Continuing from part 1 the matrix form used needs to be described. If you need a quick “tutorial” in systems of linear equations, take a look at this text I wrote. First, the vector of the unknowns – … Continue reading
Introduction This article describes a new method of measuring a lot of resistors using a low amount of wires and a lot of math. The resistors can be any kind of resistors, thermistors or other resistive sensors. It can be … Continue reading
Dear readers, After lots of work, waiting and experimenting, I have completed a text that I have sent to Circuit Cellar and they have agreed to publish it. The article deals with a new measurement technique designed to measure lots … Continue reading
The AVR controlled clock: A friend of mine needed a clock into his amplifier as an extra function. So I made him one. It consists only of one AVR processor and one BQ-M512RD (or compatible, with common anodes) LED display. … Continue reading
The purpose of this device is a bit evil. Oh well, sue me. I made it as a yoke for the first of april and many more days to come. A brief description: The device beeps a short beep of … Continue reading
The DPLC is a PLC I made for my final exams at high school. It can be programmed in a simple language, has 16 inputs and 16 outputs. It can be programed with 65536 bytes, which is equal to 8192 … Continue reading
The Concealed codelock (CC for short) is a design of mine, which can be used in a similar fashion as a safe lock, such as that on the picture above. The rotation sensor used here is just a simple 10k … Continue reading
The reason for making this project is that I was always fascinated by Conways Game of Life. It’s a great demonstration of the fact that simple things with a very simple set of rules can do wonderful things: spawn more … Continue reading
