Tons of LED dice projects with different output forms have been published online. The most common output configuration in those projects is a 3-1-3 setup (two rows of three LEDs and one LED at in the middle) of seven LEDs, which simulates the actual patterns of dots found on the six faces of a traditional […]

USB connected TI TMS320F28027 based ZRLC Tweezers with Most Digital multi-meters measure Resistance and Capacitance and LC-meters can measure Inductance and Capacitance. Presented here is a ZRLC meter which can measure Resistance, Capacitance, Inductance and Complex Impedance. The hardware is built around a TMS320F28027 micro-controller an 8-port-analog-switch ADG714 from analog-devices and a Microchip rail-to-rail dual […]

Success and reliability of a device depends not only on laboratory tests in “ideal conditions” but also on its mechanical construction. Elimination of mutual influence (EMC), optimal space usage, resistance to vibrations, easy assembly at production are one of factors why it´s worth to design mechanical part of a device into details. At production of […]

RS232 can be used to communicate between a variety of devices. Like your MCU and a GSM module or a PC. In this tutorial we will demonstrate a link between a PIC18F4520 MCU and a standard PC. On PC we will run a terminal program like RealTerm or Hyperterminal. A terminal program is used to […]

Design Goals DIY Friendly – Something that the Make audience could easily build Improve the reference design – Better measurement resolution, better timing, lower power, non-stop logging Minimal parts count – Lower cost and shorter build time Powered by a single 1.5 volt cell (AA, AAA, N or similar) and optional supplementary solar power Parts […]

Binary Watch The Binary Wristwatch Update: Due to the high demand for these, I’ve set up a batch to be professionally assembled, which should be shipping to customers April 20th.  Preorders available on my webstore. I used to get the feeling that it wasn’t obvious enough that I really enjoy working with embedded systems.  I decided […]

This reference design is a simple VGA signal generation that uses the Freescale’s MC9S08SH16VTJR, which is an 8-bit microcontroller that has Central Processor Unit (CPU) speed of 40MHz with a maximum bus frequency of 20MHz. It has an internal clock source module containing a Frequency-Locked Loop (FLL) controlled by internal or external reference. Its precision […]

Embedded system An embedded system is designed to perform one function with real-time applications. Embedded systems are found in simple devices like calculators, microwave & television remote controls and also in more complicated devices such as a home security and neighborhood traffic control systems. Many Talented people can take the advantages of simple embedded systems […]

Raw TMC data output. Low power operation with two AA (HR6) 1V2 Ni-Mh batteries or power supply. Power input range is +2.4V … +3.0V, 50..60mA without […]

The BME680 from Bosch Sensortec is the world’s first environmental sensor combining pressure, humidity, temperature, and indoor air quality in a single 3×3mm2 package. The new IC enables mobile devices and wearables to monitor indoor air quality measurement in a low power, small footprint package. The level of integration is what makes this solution so […]
