The free design tool is the software accompaniment to ADI’s complete portfolio of RF-to-digital functional blocks, allowing engineers to model RF signal chains using devices from across ADI’s RF IC and data converter portfolio. ADIsimRF Version 1.7 adds a number of new device models a...
Here’s an amazing new DNA testing chip by Panasonic together with the Belgium-based research institution IMEC. It delivers DNA results within an hour: This is the chip we’ve actually developed. As you can see, it’s less than half the size of a business card. It contains everything nee...
If you have an H-Bridge drive circuit for a motor, you may need a way to monitor the load on the circuit. This circuit is nice because it provides a single output that could be monitored with a microcontroller or other device. The trick is to use current sense amplifiers and measure t...
1A DC/DC switch-mode regulators TRACO TSR-1 already found their stable place on the market and they successfully replace inefficient linear regulators. Switch-mode power supplies are still more used in all segments of power supply, to which also belongs a regulation on the side of the...
Let your Arduino project deliver realtime notes to your iPhone or Mac with our iSticky/Arduino library! iSticky lets users send an infinite number of sticky notes to themselves and others, providing a quick, real-time solution for sending important information like reminders, updates,...
HackEDA is an online automatic circuit design tool that compiles different Eagle schematics and boards to build a complete schematic. This is now possible because Cadsoft switched to an open XML text format for board files: [via ] At it’s core, it’s a system for collecting reusable-si...
Here’s a tutorial on interfacing MAX7219 LED driver chip to Netduino platform for driving 8 digits of seven segment LED displays. The .NET Micro FramWork provides a SPI class that is used to send display data to the MAX7219 chip through a SPI serial interface.
is a DIY microcontroller-based indoor thermometer plus hygrometer that displays temperature (F/C) and relative humidity on 4 seven segment LED displays which adjust their brightness level according to the surrounding illumination. The displays are 1 inch big, emits bright yellow color...
