A diverse group of coders, makers, artists, scientists, system security researchers creating a hacker/maker space in Atlanta Georgia. We create new and exciting projects using diverse knowledge and teach free classes on a multitude of topics for the general public.
Now that winter is coming to the northern hemisphere, getting up for work means getting out of bed before the sun comes up. In order to help the natural waking mechanism of light, I've decided to hack together a sunrise alarm clock on a shoestring budget. Part List: Arduino Real Time Clock Module ( http://www.sparkfun.com/products/99 ) 24xAssorted LEDs (In my case: 3UV, 2 Blue, 4 Red, 3 Yellow, 12 White) 24xResistors, 220ohm Solderless Breadboard Assorted wires 3x74HC595 shift registers A Shadow Display Box Frosting Spray To put this thing together I used Elco's ShiftPWM Library to control the 24 LEDs. You could go bigger, but I wanted this to all fit into the box. Personally, I had some PCBs from a previous project that I could fashion to make the LEDs easier to mount. Everything is hooked up like in the schematic: The "To SCL" and "To SDA" lines go to the Real Time Clock Module. The parts are all mounted to the backing board of the shadow display box lik
I am coming to freeside tonight. I should be there around 7.30pm I finished the hardware build of the new dual extruders from makerbot. Also their new interface kit build. I'll be installing them and doing the software work, calibration and hopefully a print or new design for the dual extruders before the night is up. Since I am going to be in the space anyway, I am going to open this to anyone who wants to attend. If you are bored or free try to stop by...
