Xilinx coolrunner startup currentview story

http://forum.allaboutcircuits.com – Hi, I plan to use the coolrunner II CPLD in a very low power system, and I am not sure if the datasheet is not missing the startup current, as other companies state this number (could be beacuse their chips are flash based and the coolrunner seems to be eeprom based, but you never know).

Is building a computer for a first year project feasible?view story

http://forum.allaboutcircuits.com – Hi, I'm a first year undergrad', and with every project I always get excited. For the final year I want to design and build a computer, so this gives me, roughly, two years to prepare. This computer will not be a "kit". The only kit part to it will be the power supply, I/O, and memory. (Embedded)

Who knows about available surveillance cameras?view story

http://forum.allaboutcircuits.com – A customer needs a surveillance camera. If I could have anything I want, it would be battery operated, have motion detection ability, and use the local wi-fi to post a video on a computer inside the house or a website to be accessed later. What's available in retail version and how close can I get to this magical thing I have described? (Embedded)

Electrical Frequency Sound From Large Transformer?view story

http://forum.allaboutcircuits.com – Along this beach promenade in Thailand adjacent to a tourist/business district. There are about 6 transformers (2meters x 3meters x 4meters) along a 2 km distance. The project objective was to put power spaghetti lines underground. There is no " electrical frequency sound" around them and it looks like they have been abandoned and in disrepair. (Embedded)

Op Amp, LED flickerview story

http://forum.allaboutcircuits.com – I've built this op amp circuit to boost power to a PWM LED light control. I'm controlling circuit using Arduino controller. When I set the values to 0 (off), after a second or two, I start to get some light flickering. I'm not trained in electronics, so I'm guessing I may need a pull down resistor. Could use advise on if I'm correct, and where I might need to place them. (Embedded)
