Hi again Phrak could you please tell me what type of power supply this is. I would like to read more about it. I need to know about this circuit before I start to assemble it. But it sounds like a nice simply power supply for my needs. Thanks

Thanks unplebeian for the help. Will try this and let you Know how it works out.

The colours are important. If plants are to grow, they need light energy to create photosynthesis Most plants absorb light in the blue and red end of the spectrum. Some flourescent tubes are okay to use for seedlings and to help on cloudy days, they also emit light in many directions and even...

I'm not including green as it does little for plant growth. Photosynthesis is most active in blue (450nm) and red (660nm) light. Unplebeian can you give me some more details on what this configuation would look like. As I haven't built anything like this before. Also I picked up 20 cheap white...

The leds I was looking at are 3.5v 30mA with max of 40mA for the blue and 1.9v 30mA with max of 150mA for the red. I was thinking of 150 of the red leds and 50 of the blue. The leds were from superbrightleds.com mentioned above. the product codes are RL5-B4630 AND RL5-R1330. Sorry for not...

I'm thinking of making a 200 led grow light using red and blue leds(5v). I have little knowlage on electronics. I was wonder if a computer power supply could be used and what other componets would be needed. I'm trying to get this built by late February to start growing my veggies (new project...

This has been tried and he thinks he could get better results with a 2 track system. Also he wants to pick up some accustics from the guitar as he drums on it. He plays a similar style as Justin King.

My son wants to record both voice and instruments on his computer. He has a mixer but it only records (on pc) one track for both. He needs two tracks. Would two sound cards be able to do this? This is for a new pc that I'm buying so any suggestion what I need would be a big help.

Can anyone supply some details abount this type of cooling. Sounds interesting. Thanks Pat M
