Arduino |Automatically Save Variables to EEPROM on Power-Down

A recurring challenge for Arduino projects is that variables are volatile and will be lost completely unless previously stored to some sort of non-volatile storage such as de inbuilt EEPROM. This article shows a minimalistic approach to detect sudden loss of power and automatically store a variable to an EEPROM adress. First I should mention […]

Diamex Prog-S2 | Arduino IDE

The Diamex Prog-S2 is an universal USB ISP programmer vor various microcontrollers including Atmel AVRs. This article shows how to integrate the programmer into the Arduino IDE There are a few articles on the web that talk about the Diamex Prog-S2 and Arduino. But it seemed to me like they were either outdated or faulty. […]

AT&T go Phone Service for GSM Modules

When playing with GSM/GPRS modules for Arduino and other platforms, one is faced with the selection of a cell phone carrier that supports such devices. This article is going to show how to use AT&T’s go phone service for GSM modules. For my SIM900 powered GPRS Shield V2.0 from seed [1] I needed to find […]

Realtime GPS Tracker w. SD Card Logger Part 2 | Google Maps Link

This article shows how to build a realtime text message GPS tracker with integrated SD card logger. It allows coarse realtime tracking and more precise post analysis through the logged data. Not too long ago I wrote an article featuring a Realtime GPS Tracker w. SD Card Logger. That project sends raw NMEA [1] sentences […]

Realtime GPS Tracker w. SD Card Logger

This article shows how to build a GPS tracker that sends NMEA GPS sentences to a remote device in realtime. At the same time it logs position information onto a SD card. A while ago I got a bunch of SIM900 GSM shields, the GPRS Shield V2.0 from seed [1]. Looking for project ideas I […]

Hacking a Strobe Light Controller

Not too long ago I bought some white strobe lights with a strobe controller of Amazon. This exact controller is spread all over Amazon and eBay but only provides strobe patterns that I didn’t particularly like. So it’s time for a hack. The strobe lights I purchased were white in color but they have the […]

Review: ADSP-BF592 EZ Lite Kit

Blackfin processors from Analog Devices (ADI) precede their reputation. Anyone who has even remotely thought about Digital Signal Processors (DSPs) has come across ADI’s Blackfin processor series. ADI considers the BF592 as the low-cost entry point into the Blackfin portfolio of processors. To make evaluation a piece of cake, ADI offers the BF592 EZ-KIT Lite […]

Review: STM32 F3-series Discovery Kit

STM’s STM32 F3 series of microcontrollers offer 32-bit performance with DSP functionality. To make the evaluation of this microcontroller easier, STMicroelectronics offers an evaluation board called the STM32F3DISCOVERY. If you have ever wanted to experiment with an RISC microcontroller that comes with special Digital Signal Processing (DSP) capability, the STM32F3DISCOVERY board might just be the […]

Freescale’s Kinetis L-Series ARM® Cortex™-M0+ based MCUs

Freescale announced a new line of ARM® Cortex™-M0+ based microcontrollers, the Kinetis L Series. The MCUs are supposed to offer the performance of a real 32-bit MCU at the price and energy rating of an 8-bit microcontroller. A tight budget and low power requirements used to limit design engineers to 8-bit and 16-bit MCUs. Freescale’s […]
