For our ECE 4760 final project, we designed and built a bicycle dashboard which displays the cyclist’s pedaling power, speed, cadence, and distance to enhance training. The major motivation of this project was to replicate a commercial product at a dramatically reduced price point. A commercial power meter costs around $1000 for just the instrumented
we designed and implemented a speaker recognition device that acts as a lock triggered by the sound of your voice saying a specific passcode. The implementation uses hardware filtering from a microphone and many signal processing concepts in software. All software and matching is implemented in the ATmega1284p. The lock has two modes: training and
STMicroelectronics’ high-accuracy and low-power two-axis linear accelerometer includes digital output. The STMicroelectronics IIS2ICLX is a high-accuracy (ultra-low noise, high stability and repeatability) and low-power two-axis linear accelerometer with digital output. The IIS2ICLX has a selectable full scale of ±0.5/±1/±2/±3 g and is capable of providing the measured accelerations to the application over an I²C or SPI digital

I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and should have some sort of constant

The DC205 low-noise, high-resolution DC voltage source is the right tool when a precision bias source is needed. Its bipolar, four-quadrant output delivers up to 100 V with 1 µV resolution and up to 50 mA of current. In 4-wire mode (remote sense), the instrument corrects for lead resistance delivering accurate potential to your load.

Dimmers provide a way to reduce the power of resistive elements like heaters and light features by changing the waveform of the voltage applied to them. There are different approaches to the development/implementation of dimmers and there are a lot of how-to guides and projects based on them, but the general efficiency of these solutions
