Jie Qi from the MIT Media Lab and Bunnie from Studio Kosagi are hoping to crowdfund their idea for a new method of circuit building called Circuit Stickers.
A crossover between high tech and arts and craft, Circuit Stickers are not a serious prototyping tool but aim to find new uses for easily configurable electronics circuits so that they can be incorporated into other media such as books (basic science or fiction) or even wearable electronics.
Interconnect and power tracks made from sticky copper tape (or other conducting material) are laid out on any non conducting surface such as paper, material or flexible fabric. The individual components come ready-mounted and connect to the copper tracks via pads with sticky anisotropic (Z) tape. These can be peeled off later for reuse. There are two kits available containing a sketchbook to take you through the basics, colored LEDs, sound, light and trigger sensors and a tiny microcontroller with an ISP programming connector. That old Tee shirt looking a bit tired? Spruce it up with a running light display. [via]

Frank Zhao posted his STM32F4 breakout board [via]:
I really like the STM32 family of ARM microcontrollers. This breakout board is a narrow design that fits perfectly on a breadboard. Every pin is accessible. It has USB, a reset button, and a bootload button. The chip itself has a permanent USB bootloader that is activated by the bootload button. This means that no equipment is required to program this microcontroller, no expensive debugger, nothing at all except a USB cable.
Design files are open source and can be downloaded, there is also a short video about the bootloader and more instructions
I am also giving away blank PCBs to those interested (see “giveaway” on my page), Seeed makes more than I need, every single time

BO.Duino is an Arduino compatible board based on ATmega328 ATMEL’s mcu. This board features many peripherals usually externally connected on a breadboard or prototyping board such as sensors, SD card etc. Peripherals included are:
- A real-time clock
- AT24 series external memory chip
- MicroSD card adaptor (SPI)
- RGB LED
- A potentiometer on analog input
- Connector for DS18b20 or DHt11 series sensors

Hi, I recently built a reflow toaster oven using an Arduino. I know it’s pretty standard stuff, but my version has an automatic oven door opener (using a servo) and circulation fan to speed up the cooling time, and remote notification using an RF transmitter

I grew fond of NXPs new LPC800 Cortex M0+ microcontrollers. I designed a small breakout for the LPC812 TSSOP20. This is the second revision. It includes push buttons for reset and activating the serial bootloader. The board has an integrated 500mA 3.3V LDO to supply both the MCU and connected devices from the USB port. The four pins on the top side (5V,RX,TX,GND) can be used to connect a cheap USB to serial adapter and program the device via the internal bootloader using FlashMagic.

Light destroys art. Some wavelengths are more damaging, some media are more vulnerable to damage, but all curators and conservators face a fundamental conflict between the demands of preservation and the desire to display the objects in their care. These conflicts come to the forefront whenever a museum must decide which objects to display, for how long, and with what illumination. The recent emergence of museum-quality LED lighting is challenging existing assumptions about the “best” lighting for art objects.

The human-machine interface, once simply known as an “operator panel” or “terminal”, is changing rapidly, due to the graphical, visual way operators now interact with an industrial machine or process. At one time, designers of these systems could get by with a three-line segmented LCD display. Today, LCD interfaces are quickly replacing traditional LED and segment LCD displays as designers take advantage of the aesthetic, flexibility, and cost benefits they provide.

The compact FPV system I have built is only about 20g, now even my mini quadcopter and micro hexacopter can carry this FPV camera and video transmitter. In this post I will share with you what are the parts you will need and how I made it.

This interesting spray from the Kontakt Chemie portfolio will serve in an office but also at the production of electronics and in many other segments.
Name “Label off” discloses a main purpose of usage of this spray. But that´s not all. Because Label Off is a mixture of solvents which particularly well dissolve sticky substances, it can be successfully used everywhere, where it´s necessary to remove residues after adhesive tapes or other hard-to-remove substances like tar and tree resin. Despite a considerable effect, the spray is considerate to many plastics, only can´t be used on polystyrene and polycarbonate. Label Off can be even used on a cardboard/ paper boxes.
Label Off acts very simply – all that is necessary is to spray a thin layer to a label or other place, which we want to clean and wait approx- 2 minutes. After this time it´s usually possible to peel-off a label without residues. Occasional residues can be removed by a repeated application of Label Off and wiping by a (paper) cloth.
Detailed information will provide you the Label Off datasheet.
