The FT232 USB-to-serial converter is one of the most commonly-used methods of adding USB functionality to small projects, but recently I found that these chips are capable of sending more than just serial signals. With some creative programming, individual output pins can be big-banged to emulate a clock, data, and chip select line to control […]

My hobby and passion is to realize physics projects. One of my last work is about ultrasonic sonography. As always I tried to make it as simple as possible with parts you can get on ebay or aliexpress. So let’s take a look how far I can go with my simple items… I was inspired

Hi guys, welcome to today’s tutorial. In this tutorial we will look at how to use the TCS230 color sensor with Arduino. To demonstrate the ability of the color sensor, we will build a color detector system capable of detecting the color in front of the sensor and displaying that color on a TFT Display.

The bq25504 from Texas Instruments is a good candidate to become a milestone on the road to micro-power management and energy harvesting. A prominent feature of this IC is its ability to start up at a supply voltage as low as 330 mV typically, and 450 mV guaranteed. With an SMD inductor and a few

[Engineer2you] built a nixie tube clock and claims it is the simplest design. We felt like that was a challenge. In this design, the tubes are set up as a matrix with optoisolators on each row and column. With 60 segments, the matrix allows you to control it all with 16 bits. There are six columns, each

Introduction Hi guys, continuing on our recent path of building really cool stuffs based on the Nokia 5110 LCD display, today we will be building a DIY Lux (or light) meter using the highly sensitive BH1750 light sensor. Illuminance (measured in LUX) is the total luminous flux incident on a surface, per unit area. It is a

Signal analysis: quick results See small signal details in the presence of large signals The R&S®RTM3000 features a customized Rohde & Schwarz designed 10-bit A/D converter that delivers a four-fold improvement over conventional 8-bit A/D converters. The increased resolution results in sharper waveforms with more signal details that would otherwise be missed. One example is

[minh7a6] loves the Adafruit Feather, but sees some room for improvement. First is the matter of 5V tolerance. While just about everything is available in a 3.3v range these days, sometimes it’s just nice not to have to care. The main controller on the Feather is plenty powerful, but its intolerant pins just wouldn’t do so
