Beekeepers dream – PIC32 based bee hive monitor

If you are a beekeeper this project can be a good start towards better beekeeping. It is based on PIC32 microcontroller and has tons of sensors and interfacing that allows controlling many parameters in order to sustain near ideal conditions in a bee hive. If you know a little about bees, the probably you are aware about bee Colony Collapse Disorder (CCD), when number of worker bees drops and this way rest of them aren’t able to maintain hive.

So it is better to prevent this factor than fix damage later. This is where PIC32 based monitor (so called PIC’n The Beehive) comes in. It monitors ambient and hive temperatures, humidity, rain, dew point, wind speed, relative air pressure, and daylight intensity. It is also capable of measuring hive and bee weight and Mite count as well. Due to condition changes controller can ventilate hive, regulate temperature, entrance opening. It also can simulate rain to keep bees inside. All data can be accessed via multiple interfaces like USB, RS232, RF channel and even via WEB interface. This is what modern bee life should look like :)

Play Rock Paper Scissors against your glove

It may sound little bit crazy, but yeah – you can play Rock Paper Scissors alone…with your glove. OK this isn’t just regular glove, but really hacked glove that can compete with you in this simple but catchy game.

Glove is equipped with Arduino Mini Pro board that is equipped with triple axis accelerometer that is already mounted on breakout board from sparkfun. Also it has couple of flex sensors for detecting positions of “scissor” fingers. It works fine, but seems that it can be simplified with less expensive parts. Anyway this is great toy to beat time.

New BlueBoard-LPC1768-H has been released

Continuing with its endeavor to deliver low cost micro controller hardware development platform, NGX has now launched a new low cost prototyping platform for LPC1768 series of mircocontrollers. LPC1700 are ARM cortex-M3 based micro controllers. The platform is named BlueBoard-LPC1768-H and costs only $32.5

BlueBoard-LPC1768-H is a breakout board for LPC1768 cortex-M3 based microcontroller. The LPC1768 microcontroller has 512KB of internal flash and 64KB RAM. Ethernet MAC, USB Device/Host/OTG interface, 8-channel general purpose DMA controller, 4 UARTs, 2 CAN channels, 2 SSP controllers, SPI interface, 3 I2C-bus interfaces, 2-input plus 2-output I2S-bus interface, 8-channel 12-bit ADC, 10-bit DAC, motor control PWM, Quadrature Encoder interface, 4 general purpose timers, 6-output general purpose PWM, ultra-low power Real-Time Clock (RTC) with separate battery supply, and up to 70 general purpose I/O pins

Board can be purchased from

Motorduino – an excellent board to start with robotics

Probably you know that programming Arduino is easy task even for novice. So if you are just starting electronics and looking towards robotics, this Motorduino might be a great starting point.

This board equipped with all necessary interfaces to start with various motors including regular and servos. It also allows easily adding various sensors without additional need of Arduino shields. Despite various peripherals, Motorduino is still compatible with additional standard Duemilanove shields just in case you need more interfacing or expanding. They are working on final tweaks before letting board out. Stay tuned.

AVR TV terminal

This TV terminal made by Vassilis Serasidis has been around quite some time and served lots of people as a great project or at least as reference to new designs. If you missed it – you just need to check it out. Well this TV terminal can completely replace any indicator that you usually use in your embedded design.

So TV terminal is capable of displaying 40 chars in 25 lines or 80×75 points in semi graphical mode. TV terminal is built around ATmega8 microcontroller that is clocked at 20MHz and it is still a trade off because originally 22MHz would be needed. Despite sending info to TV device also accepts keystrokes from standard PC keyboard and data from RS232 channel. So this makes device pretty universal which can act as a TV display controller for other embedded projects or simply accept data from PC via RS232 interface.
