The Analog Swiss Army Knife IC

Interfacing digital electronics to analog world is needed in many applications. There have been several attempts at devices that might be called field-programmable analog arrays (FPAAs) over the years, but most have failed to establish a significant market presence (maybe except Cypress Semiconductor PSoC). The Analog Swiss Army Knife article tells that without a proper

Interesting Analog Design Kits

I have read more than year ago (2012) interesting articles about Digilent‘s Analog Discovery Kit. I even quickly tried the WaveForms Software the cames with it (freely available and testable without hardware). It looked interesting, but I decided that maybe I don’t at the moment need this and skipped it (I did not even write

HT-USBee AxPro review

I found a cheap mixed signal oscilloscope product: HT-USBee AxPro. This HT-USBee AxPro is a said to be 8 Channel Logic Analyzer Oscilloscope Compatible USBee AX Pro I2C IIC SPI CAN Debugger. It features Oscilloscope Input (single channel, 16Msps, 3MHz bandwidth) and 8-CH Logic Analyzer. With suitable software it can be used as Data Recorder,

IOIO-OTG board review

I was some day wondering how to connect IO to Android smartphone or tablet.One well known option is to use IOIO or IOIO-OTG board connected to Android device USB port. The IOIO (pronounced “yo-yo”) is a board specially designed to work with Android devices and robust connectivity to an Android device via a USB or

Freaduino Leonardo review

Arduino Leonardo is a micro-controller board based on the ATmega32u4. This board form factor and functionality is quite similar to Arduino UNO (7.1 cm x 5.3 cm x 1.5 cm ; 20 g) , with the exception that the USB interface is built into the micro-controller itself instead of using external serial-USB converter IC on

LED shield for Arduino

When testing with Arduino circuits, it is often useful to see digital signal states on different pins. It is easy to measure single signal pin state with multimeter, but when you want to monitor several pins visually you need something else. One useful option is to use LEDs connected to pins to show their state.

Arduino Ethernet Shield

The Arduino Ethernet Shield allows you to connects Arduino to your local LAN or Internet with Ethernet connection.. Just plug Arduino Ethernet Shield module onto your Arduino board, connect it to your network with an RJ45 cable. The original Arduino Ethernet Shield is based on the Wiznet W5100 Ethernet chip. Arduino IDE comes with example

Cheap Arduino Nano Review

I found a very cheap Arduino Nano board from Bang good web shop. I consider 5.34 Euros very cheap price for Arduino Nano, usually those cost $10 or even considerably more. Gravitech lists on it’s web page price to be $34.99. I wonder how this board can get this be built and delivered from other

littlebits

One friend mentioned this: littleBits makes an opensource library of electronic modules that snap together with tiny magnets for prototyping, learning, and fun. Looks interesting. There are even instructions how to join littleBits to LEGO. All the  modules are open source, check  GitHub for Eagle boards and schematics for all the littleBits modules. The aim

Bang good web shop

I have bout a lot of stuff from Dealextreme web shop that I mentioned some years ago at  my blog posting. I can still recommend that place like I did years ago. Now I have found another interesting looking place which have similar products sometimes even cheaper prices. Bang Good at http://www.banggood.com/ has a lot
