## Circuit Cellar publication – a new method for measuring resistors!

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

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 Sanity nullifier

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 programmable controller

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

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
