ElectroPumpkins for Halloween

An Arduino, a bit of ws2812 LED strip, and some sanded acrylic tube make the perfect light for a jack-o-lantern.  If you’ve ever wanted to play with the intelligent LEDs like the ws2812, I highly recommend using FastLED to drive them.  The library has a good set of examples bundled with it, one of which is the Fire2012 example.  You can see that in action in the embedded video below.  For these two pumpkins, I used some very simple code that cycles them through the HSV color wheel at 100% saturation and 100% value.  See the code at the end of the post.

And now for the code:

 

#include "FastLED.h"
#define NUM_LEDS 20
#define LED_PIN 5

// Define the array of leds
CRGB leds[NUM_LEDS];

void setup() { 
   FastLED.addLeds<WS2812, LED_PIN, BGR>(leds, NUM_LEDS);
}

#define HUE_DELTA 1
#define TIMEOUT 200

void loop() {
   static uint8_t hue = 0;
   // Turn the LED on, then pause
   for( int idx = 0; idx < NUM_LEDS; idx++)
   {
      leds[idx].setHSV( hue, 0xff, 0xff);
   }
   FastLED.show();
   delay(TIMEOUT);
   hue += HUE_DELTA;
}

 

CNC Drawing class

Thursday night’s CNC Basics class went well, and will likely be a recurring class.  Be sure to keep looking on our Meetup page for the next one if you missed it.

Fall Fixin’ Stuff BBQ

This past weekend, about a dozen or so of our members spent part of Sunday afternoon spiffing up the space and enjoying a tasty BBQ. 20161023_192001

We had a crew working magic in the electronics room (behold the new ‘wall of resistance’), and another group that built a sturdy (and mobile!) base for one of our main room center tables.

A few more of us spent some time clearing the dust in the wood shop and doing some general straightening up in other parts of the space. And we couldn’t have asked for a nicer fall afternoon to open the doors and enjoy each other’s company while munching on burgers, brats, veggies, potato salad, fruit and cookies!

We had a similar event at the end of June, which resulted in a new wall-mounted table being built for the main room (seen in the background of the middle photo above). The dedication of our members is immeasurable and paramount to creating and recreating our useful and fun space. A warm and hearty thank you to all who participated in these events!
