Intel announced its 4004 processor and its chipset through an ad in Electronic News on November 15, 1971, making them the first complete CPU on one chip and the first commercially available microprocessor. The building-block 4004 CPU held 2300 transistors. The microprocessor, the size of a little fingernail, delivered the same computing power as the […]

I got my first taste of programming with RCX Code and an old Mindstorms RCX 1.0, so maybe it’s nostalgia speaking, but I really admire visual programming languages for their ability to introduce younger folks to programming. With color coded operators, geometrically shaped data types, and no semicolons (!), visual languages have a unique ability

Winter just arrived. The enemy of all batteries. Last year this was the season the auxiliary battery of my T3 VW camper bus bit the dust. This likely happened because I neglected to take care of it over the winter months during which the bus is typically parked in my garage. When the auxiliary battery

Contributed by Publitek European Editors 10/15/2013 Power MOSFETs have become very popular in power electronics designs because of their low capacitance and good high-frequency switching characteristics. They have reached into many applications and are helping to open up new markets in applications, from hybrid and electric vehicles through solar power to extreme-environment exploration. The unifying

The FT600 and FT601 are both USB 3.0 to FIFO interface chips supporting the USB 3.0 Super Speed (5 Gb/s) and USB 2.0 High Speed (480 Mb/s) data transfer standards. The FT600Q has a 16-bit wide FIFO bus interface and comes in a 56-pin QFN package while the FT601Q uses a 32-bit wide FIFO interface, packaged in a

After some months out, I come back with my last board, the SIM900 Breakout Board. It’s a board based on the popular SIM900 GSM modem, and I design to work with the DSETA board I develop previously. Also, the board can be used without this board, I try to design it in the way that

Winter is coming. So it is time to make preparations. If you live in a colder climate, you need to be concerned about the possibility of your pipes freezing. There are a lot of preventative measures that you can take such as insulating your pipes and leaving the water dripping. But for a little extra

The AD8237 is a micropower, zero drift, rail-to-rail input and output instrumentation amplifier. The relative match of two resistors sets any gain from 1 to 1000. The AD8237 has excellent gain accuracy performance that can be preserved at any gain with two ratio-matched resistors. The AD8237 employs the indirect current feedback architecture to achieve a
Two AA cell instrumentation amplifier for body networks Continue Reading
Codebender is a web-based programming tool for Arduino. ” Traditionally, you would need to install an IDE, which includes all the necessary software, find and install the correct drivers, set permissions, etc. It can take 10-60 minutes. Or it can be a total mess. With Codebender, you can program your Arduino straight from your browser.
