Project Dyson v2 - Time to revisit this project, the last one failed when the stock impeller melted solid due to the speed of the brushless motor I had attached. This time around I will be mounting an EDF inside the housing, and blowing right out the back it. With the new EDF I will have a lot more space in the main housing, allowing me to include a screen for the coolness factor. This EDF produces around 6lbs of thrust (which is enough to push an office chair across the room)… so it should be interesting to see what this can accomplish as a vacuum cleaner…
Time for me to start making stuff again… It has been FAAARRRR too long. I whipped this together at lunch time today, simple 3 channel PWM using TIP142s. It is driving a 30W RGB LED at 30V, and at peak it runs around 1.8A of draw.
My goal is to use these to wash a few walls in my office with color.
My anti backlash ball screws, rails and linear bearings arrived! This CNC table is going to be massive!
30W RGB Led Test - Before I pack all this up tomorrow I decided to test out one of the 30W RGB LEDs I got to do accent lighting for my new office. It is powered by 3 individual drivers that accept PWM input to drive the output. Each LED module+driver combo will have 1 arduino pro mini driving the PWM input. All the pro mini’s will i2c together with an arduino that sits on the network for network control of the 4 individual LEDs.
Packing my components for our upcoming move! It’s nice to be a little organized for once…
jsSTK500 update! Initialization is now working! I refactored the code to better work the way you would expect it (with callbacks etc).

30W RGB LED. A few weeks ago i ordered 4 30W RGB LEDS and drivers. They arrived today, and they are HUGE! Here is a size comparison against a Pinoccio Scout and my business card.
Scout6050 - I was asked to put together a quick video showing off my Scout6050 project thus far. Here it is.
Premise is simple… It’s a wifi connected theramin! Yaw controls pitch, roll controls volume… It’s a work in progress but a working one! I am fully impressed in the speed of Mosquitto (the mqtt daemon im using). Latency from the pinoccio, over wifi, through the mqtt daemon, through lighthttpd’s websocket broker over my LAN to my browser then decoded via json and rendered is MINIMAL… Infact, its so quick and precise it seems like its actually creating the tone itself, even tho my computer is.
