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. →
I saw an interesting kit at banggood.com and decided to try it: DIY Meter Tester Kit For Capacitance ESR Inductance Resistor NPN PNP Mosfet M168 . The reasons for interests are good specifications, based on open source hardware design and price is reasonable ($12.22 / 9.37 Euro). DIY Meter Tester Kit For Capacitance ESR Inductance →
