Hacking toy RC cars
Project Lab provides the details on how to produce a wireless robotics platform using a cheap RC toy vehicle, Arduino, XBee and Processing. The vehicle is completely controlled by the code running on the remote computer which allows very rapid prototyping of the code to tell the vehicle what to do and how to react […]
Xilinx free FPGA/CPLD design tutorials
The Arduino platform and bare microcontrollers are good ways to get started in developing embedded systems. But the way of the future is clearly CPLD and FPGA architecture. These devices are not simply a new type of chip, but a new and interesting design and development frontier. Their programs are developed using several methods, including […]
Tweet-A-Pot
How do you make a good cup of coffee while traveling home? Mix equal parts of your computer, Arduino, automatic coffee maker, Power Tail Switch and Twitter! In this Instructables, frenzy shows how to setup a Python interface between the Arduino and Twitter, connect the Power Tail Switch between Arduino Pin 13 and ground, and […]
Handling exceptions in Processing
Here’s some interesting information from the MAKE Codebox about how to handle errors and exceptions which appear in the Processing IDE. A good look at what causes exceptions along with suggestions on how to deal with them.
Nimbits
Nimbits is a free, social and open source data logging system. It provides a mechanism for recording time series data, such as a changing temperature or stock price, into a data channel called a “Data Point”. Your data is stored on a global cloud computing infrastructure that provides remarkable uptime and scalability. You can download […]
Wireshark analysis of wireless protocols
FreakLabs has an interesting project designed to conduct sniffing of protocols that ride on top of 802.15.4 such as Zigbee and 6LoWPAN (IPv6 over 802.15.4). The project utilizes their FreakDuino platform which contains an Arduino integrated with a wireless radio. The tutorial assumes that Wireshark is installed on your computer, the Chibi or chibiArduino release […]
Internet Troll sniffing rat
Mike sent in his first Arduino project, an internet troll sniffing rat: Sometimes we like to take a few minutes away from Hackaday to spend time with our families. But just when you take your eyes off of the incoming comments, Trolls are bound to strike. Well, [Caleb] and I found a solution to the […]
HUGE wireless RGB LED display
siklosi saw the post about using a wifi router as an Arduino wireless serial connection, and shared his own take. This RGB LED wall is plays Winamp visualizations, and more. The LEDs are driven by Rainbowduinos, the Rainbowduinos are connected to the PC using the router as a wireless serial connection. I made this “little” […]
DEMO: 96×16 OLED display
It has been a while since a demonstration was posted. We whipping up new projects for you like the USB LCD backpack, HVP adapter, Buspirate v4 prototype, breakout boards, and several other project that are TOP-SECRET but will be released soon! Now that everything is at to manufacturing, we have some time off for our family and for fun stuff. […]
Vinculum-II (VNC2) development platform
FTDI released a development board for the Vinculum-II (VNC2) inspired by the Arduino. The Vinculo has an Arduino shield pinout, with an extra row of 10 pins on the digital side. The Vinculo is a dual channel USB Host/Device Controller is targeted at rapid development and prototyping of USB Host/Device interfaces. Vinculo…can be programmed using […]
Papilio barcode genie, a barcode scanning kit
The Gadget Factory, co-designer of the Open Logic Sniffer, has a new portable barcode scanning kit based on the Papilio FPGA platform. It is called the Papilio Barcode Genie kit or Barcode Genie for short. It is a kit for the Papilio One that makes it easy to capture barcodes and save them to a […]
A PIC/AVR burning robot
RoboProgrammer is a robotic microcontroller programmer. It’s an Arduino-heavy design – a GRoboduino is used to control the robot, and a Duemilanove is used to program the AVR chips. Via Hack a Day.
Infrared sensor tutorial
Adafruit has a new infrared sensor tutorial that uses an Arduino to clone an infrared remote control signal. They use a time-based protocol decoder/cloner, similar to the infrared sampling mode used in the USB IR Toy. SB-Projects has more excellent infrared remote control protocol details.
Seeeduino Film V0.9b
The Seeeduino Film we covered earlier is now available. Film is a flexible development board that includes an Atmega168 with the Arduino bootloader. For portable or wearable applications, it has an on-board li-poly battery charger. Albert has been working hard to get this design right, congraduations on the first batch! Maybe when this is perfected […]
Inexpensive multi-programmer update
An update of the inexpensive, medium-speed AVR/PIC/CPLD/Arduino programmer is posted in the forum. This programmer is designed for people who don’t own a programmer, and just want to rescue a bricked PIC or AVR. This version takes into account the pin connection diagram MichaelZ outlined during our last design review. The update has a single […]
Preview: Inexpensive multi-chip programmer
This is a preview of an inexpensive, medium-speed AVR/PIC/CPLD/Arduino programmer. It’s designed for people who don’t own a programmer and just want to rescue a bricked PIC or AVR. The programmer uses the bitbang mode of a FT232R FTDI USB->serial converter chip. The same one used on the Bus Pirate and Arduino. There’s existing apps […]
LaunchPad MSP430 development board
Texas Instruments is putting out a $4.30 development platform for the 16bit MSP430 microcontroller. The LaunchPad is aimed at beginners and hobbyists. It accepts several different through-hole chips from the MSP430 value line. We like to use the MSP430 in simple low power designs, but the 4K and 8K size limits on the compiler can […]
Several PIC UART calculator utilities
Simple serial communication, legacy or with a USB->serial converter, remains a common interface for microcontrollers. The Bus Pirate uses it, the Arduino uses it, lots of hobby projects rely on a serial data link. Most Microchip PIC microcontrollers have a UART, hardware that simplifies serial communications. The serial speed is set by programming the baud […]
Logic Sniffer mention in Nuts & Volts
Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. The Logic Sniffer got a mention in a Nuts & Volts article titled Reading and Writing an EEPROM Using the […]
