Dance of the X Rays

From the ESA Image of the Day – this is a truly remarkable image. Taken from the ESA XMM-Newton Space Telescope, as it shifts its gaze from one X Ray object to another – it shows some notable celestial objects. Its a mosaic of 73,178 individual images adjusted for the Galactic projection/ plane lying across the centre of the image.

Bright object on the right: Vela supernova, 150 x larger than a full moon. On the left is Cygnus Loop, an expanding shock wave caused by a star ending in a supernova <15k years ago. At the centre is Scorpius X-1 – the first object/source to be discovered through X-Rays alone, at 9000 light years from the Earth and is the strongest source of X-Rays apart from our own Sun. My eyesight fails me to recognise the Small and Large Magellanic Clouds – dwarf galaxies neighbours within the Milky Way.

This image covers 62% of the sky and these 1200 individual slews were recorded just between 2011-12. Links to the ever expanding database from XMM-Newton at:

WICED™ | Broadcom

Must look closely at the Broadcom Wireless Internet connectivity for embedded devices –

Broadcom’s Wireless Internet Connectivity for Embedded Devices (WICED™) platform (pronounced “wik-id”) eases development effort and simplifies the implementation of Internet connectivity in an array of consumer devices, especially those without existing support for networking.

Developers use the WICED platform to create secure wireless networking applications on a wide array of platforms encompassing Broadcom wireless connectivity technologies. The WICED platform encompasses.

From Siggraph – balancing 3D printed objects

Balance is a delicate compromise between shape, weight and pose. To give a feel of dynamism, many 3D rendered objects stand in impossibly balanced configurations. As soon as you try and print these, the illusion meets gravity, very often sounding in a small thud. Whilst there are several other laser cut support options available as are stress evaluating and relief algorithms, this is a rather simple polygon based method offering to optimise print designs to make the objects balance.

Open Hardware Summit 2013 badge sneak peek – YouTube

Open Hardware Summit 2013 badge sneak peek – YouTube. – Brilliant vcard inclusion and schedule program (last year and this year) – would be an ideal way to reprogram and make it personalised. The landyard points are also connectors – awesome AND – it runs on a coin cell that allows it 100 page turns or if not excessively used run for the entire length of the conference. Up there with the best of Defcon badges

DIY Pick and Place just getting under way

Long road still to travel, but a DIY Pick and Place attempt here.



It’s not totally fair to say that this project is just getting under way. But the truth is it neither picks nor places so there’s a long road still to travel. But we’re impressed with the demonstrations of what [Daniel Amesberger] has achieved thus far. Using the simplest of CNC mills he’s finished the frame and gantry for the device. You can see some of the parts on the left after going though an anodizing process that leaves them with that slick black finish.

The demo video shows off the device by driving it with a joystick. It’s fast, which gives us hope that this will rival some of the low-end commercial pick and place machines. He’s already been working on the software, which runs on a mini ITX form factor computer. This includes a gerber file interpreter and some computer vision for a visual check on part placement. He hasn’t…
