RX833 750W Power supply

Tracking down some schematics

• youtube video of RX833

Wow, that is a loud fan.  I guess it's even louder when it doesn't have a server rack wrapped around it.  Sounds like a jet getting ready to take off.  That's really unfortunate.  It's more efficient then then an array of HPS.  All 12V also, so only real danger is that the power supply will go out.  It's a pretty safe device.  62A possible output, 40A expected output.

LED's (50k hrs)

• low bright leds - 3528 (2A/5m)
• high brightness leds - 5630 ($6/5m) (5A/5m)
• double row low bright - 3528 (8A/5m)
• double row high bright - 5050 (10A/5m)

Those are banana plugs for the 12V connections and the switches are single throw, double pole, but only one side is used.  Next step is drilling channels for wires to power each array of LEDs.  So excited that the power supply is all wired up etc.   My 5 year old daughter was helping me with the wiring and had some very interesting questions about the internal workings of the power supply.

Kids books

Some ideas for children's books

• Emma plants an apple seed
• Emma learns about farming
• conserving water / water use
• composting
• some kind of a textbook

Things to do:

• Clean
• fix toilets
• work on truck
• build garden boxes
• drop compost (into soil)
• clean side yard

So much to do.  I guess that's just a symptom of living in an actual environment.

Emma and I are thinking about making some books for her to read, using the words that she knows.  She's an excellent reader and knows all her words from school, plus the ones that she's learned on her own.
