Some time ago, I stumbled upon an article about 25¢ I²C adapter. I usually use my Raspberry Pi to interface with I²C devices, but having it right on my notebook seemed like quite useful thing, so I decided to build a project around it. Probing Altough the mentioned article says that I²C is not supported […]

At the end of this month, I’ll be leaving my current job. I therefore thought it’d be a nice occasion to build a new business card for my future interviews: You may remember the first version of my business card made more than one and a half years ago (time flies!). It was basically made

Texas Instruments designers have developed an entirely new data converter with the LDC1000 inductance-to-digital converter (LDC) designed specifically for inductive sensing applications. The LDC uniquely combines all of the external circuitry on chip that is normally required to simultaneously measure the impedance and resonant frequency of an LC resonator. It then regulates the oscillation amplitude

Project Summary: The Tinusaur is a small board with a ATtiny85 micro-controller on it. The board has the minimum required components for the micro-controller to work properly. It also has few headers to connect external components and connector for ISP programmer. The board could work with any of those DIP-8 chips such as ATtiny25/ATtiny45/ATtiny85, ATtiny13

Until recenty my desktop computer has always shared a room with a Hi-Fi setup so there has never been a need for using decent speakers with the computer. When the desktop computer was moved into it’s own room (with no HiFi) I quickly realized that good speakers were now required for decent quality music playback.

The circuit in Figure 1 lets you switch high-voltage power to a grounded load with a low-voltage control signal. The circuit also functions as a submicrosecond circuit breaker that protects the power source against load faults. Power switches to the load when you apply a logic-level signal to the output control terminal. circuitWhen the signal

With a height of only 4.5 mm are new terminal blocks able to connect LED modules and LED panels aesthetically and with a maximal reliability. There are numerous SMT connectors on the market, which are suitable for usage on LED panels but even in other applications. That´s why it´s a logic question – why just

My most rewarding projects are the ones which i actually use. I like my audio gear so, this was the perfect companion project! On my desk i have a headphone amplifier for my AKG K702’s headphones, below it i have my self built Onixia integrated amplifier for my bookshelf speakers. I have been thinking about making a

In an effort to resume previous work [A, B, C, D] on developing a crystal oven for radio frequency transmitter / receiver stabilization purposes, the first step for me was to create a device to accurately measure and log temperature. I did this with common, cheap components, and the output is saved to the computer (over 1,000 readings
