It is scary how many industries (e.g. autos, “smart” electronics, control systems) are decades behind state of the art security. It’s Easy To Hack Traffic Lights Slashdot posting tells about article where research from the University of Michigan are into the ease with which attackers can hack traffic lights. The network is IP-based, with all →
Watch a Hacker Fry a Hair Dryer With Her Radio article shows that a handheld directional radio antenna can be used to to fry a ground fault circuit interrupter, or GFCI: GFCIs integrated into household appliances like hair dryers and heaters or wall outlets, mischievously switching them off or making the plugs shake, spark and →

I needed to replace few burned 50W GU10 halogen bulbs with LEDs. A standard 50W halogen lamp outputs 400 lumens so I needed to find a reasonably LED bulb that gives around the same light output. I could live with slightly less, but not too much less. I found suitable looking product AIRAM LED 4W →
LEDs Bring New Light to Car-to-Car Communication – IEEE Spectrum http://spectrum.ieee.org/transportation/advanced-cars/leds-bring-new-light-to-car-to-car-communication This is quite interesting idea. It combines tho things I have written earlier: communicating LED lamps and car electronics. Posted from WordPress for Android →
I had to replace some 50W GU10 halogen bulbs. I though it could be time to check if it would be reasonable to go to use LED bulbs. I did a year or so similar checking, and at this time it did not feel reasonable because reasonably prices LED bulbs gave considerably less lights out →
Open Source GPU Released. GPLGPU project has developed an open source GPU, written for an FPGA, despite that GPL-GPU Kickstarter was not funded. It’s not a powerhouse but it is full open source. A completely open GPU simply didn’t exist before (only very limited thesis projects earlier). Right now, the GPL-GPU has 3D graphics acceleration →
http://www.electronicproducts.com/Power_Products/Invertors/Advanced_solar_microinverters_lay_groundwork_for_smart_grid.aspx In the span of a few years, the photovoltaic (PV) microinverter has evolved from an intriguing and potentially disruptive technological advancement to a market-leading product category in the residential and commercial solar installation market. Millions of devices have been deployed and have already helped genrate terawatt-hours of electricity from hundreds of thousands of rooftop →
LightBoost HOWTO | Blur Busters (http://www.blurbusters.com/zero-motion-blur/lightboost/) is an interesting article on technologies used to avoid motion blur on LCD monitors. LightBoost is a programmable strobe backlight. The backlight is turned off while waiting for LCD to finish pixel transitions (unseen by human eyes), and the backlight is strobed only on fully-refreshed LCD frames (seen by human →
Hot Chips: A Symposium on High Performance Chips has been known as one of the semiconductor industry’s leading conferences on high-performance microprocessors and related integrated circuits. It is concentrates on real products and realizable technology. The conference is held once a year in August in the center of the world’s capital of electronics activity, Silicon Valley. →
