A team from Caltech (California Institute of Technology) ETH Zurich and the Paul Scherrer Institute could assist the thermo-chemical production of fuels.  In a paper published in the journal Science, the researchers claim that fuel can be generated over 500 cycles. Solar to fuel efficiencies of 0.7-0.8 per cent were achieved. [via]

Altami was kind enough to offer a free licence of there software Altami Studio. This software enables you to process images in real time as captured by various devices like microscopes, telescopes etc. Demo-version of the application is available for downloading without any preliminary registrations or inquiries. Features include:

  • Live measuring and image processing
  • Great capture devices integration
  • Powerful measurement and markup abilities
  • etc

Altami Studio is designed for monitoring, processing, measuring, and marking of images received from different monitoring and capture devices: microscopes, telescopes, X-ray machines, etc. All image processing and measuring actions can be executed in real-time mode (images are received from camera or another capture devices).

This mini-tutorial will go through the process of setting up a ST7565 LCD. These LCDs are graphical which means they can display pixels, not just text. This type of LCD in particular has 128×64 pixels, which appear dark gray on a green-blue background. They have a backliight but can also be used without the light on for daytime visibility.

Mauricio Martins modified an acrylic Christmas tree by adding some LEDs controlled by a simple circuit. For this hack, he used the following components that you can buy for less than 8 euros:

  • MUJI Red Acrylic Christmas Tree
  • Resistors: 10k, 470k
  • Capacitor: 0.1µF
  • Integrated Circuit: 4060B
  • LEDs × 18, 3mm diameter, any mix of colours: red, orange, amber, yellow or green
  • Battery clip for 9V”

This project is a high voltage plasma speaker that is using two mosfets in half bridge to drive the flyback transformer. This reduces the load on the FETs, and thus reduces the heat produced by them. To find out how plasma speakers work see the bottom of this page. [via]

One of the most powerful tools to have when doing any type of design that involves communication protocols is a protocol analyzer. It allows you to see exactly what the communicating devices are seeing which is very useful for troubleshooting many types of problems that might come up… Wireshark is probably one of the most well-known of all protocol analyzers. [via]
