Last week I met with an awesome grad student in the EE department, and helped me out with some SMD soldering to the breakout boards. I made a little test rig with an ice cream canister, pencil and magnet and it looks like it is working well! Now we need to build a larger rig[…]
We purchased 15 meters of WS2811 based RGB LED strips (30 LEDS/meter). Pretty awesome stuff. Also purchased WS2801 based LED strands, 80 units, to be used for the walls. The plan is to drive the walls with FastSPI (maybe just one arduino with a 50ohm resistor on the on the last DO pin)… The mega[…]
I’ve continued working with the LED strand. I’ve individually addressed them to the board and set them up with the basic breath control and have a nice serial interface setup to test different patterns, clear out the strip, etc. I’m working on a setting up a nice resting state that features the all the lights[…]
Graham and I got together and fixed the flickering problem with the LEDs. We both initially suspected it was a coding issue, but after digging through the code thoroughly we decided that it could possibly be hardware related. We found that switching power supplies resolved the problem. The specific difference between the power supplies is[…]
After last week’s meeting I went home and started researching LED strips and settled on buying the a strip on Ebay “RGB LED Pixels 50pc 12mm Diffused 5V Waterproof Addressable Full Color”. I believed it was using the WS2801 chipset such as those sold on Adafruit, but it turns out they are based on the[…]
