Test: LED Replaces Halogen

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 →

LED vs Halogen

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

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 →

Advanced solar microinverters lay groundwork for smart grid – Electronic Products

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

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 →

Views of Hot Chips 2014
