Odd-ball notes

Polyester Dye

  • need to keep the fabric off the bottom of the pan, flat spots may have formed (found a small grate that will work for this)
  • need to weigh the fabric down so steam bubbles don't form lifting the fabric out of the dye (have a basket with weights that will work)
  • need to be above 100C for an extended period, ~45 minutes minimum
  • streaking seems to be limited to one side- turning cushion forms inside out might give a better result
  • first batch was small cushion, 50ml dye to 2L water, hue looks good aside from the streaking, trying a machine wash to see if the streaks go away
  • 2nd go on the first cushion added 4L water but no dye (so original 50ml plus whatever went into the fabric in the first round)
  • turned cushion inside out
  • basket to keep fabric off the bottom in place, weighted basket above in place
  • started cold at 10:10
  • reduced heat to 7 at 11 & stirred/shifted
  • lid should not seal perfectly- that seems to stop steam bubbles from forming
  • open and close vent periodically to prevent auto-shut-off from happening
  • pulled and rinsed in cold water at 11:45

Thinking about anemometers with no moving parts- it may be possible to use a cheap pressure sensor as a pitot tube, with a 360 degree cowling that funnels horizontal moving air upwards into the sensor (picture two smooth funnels inserted into each other). An apparently cheap & suitable sensor for Arduino is: Coupled with a GPS chip to get SOG & COG, apparent and real wind speed could be directly output in NMEA0183 format. Add wind direction and done.

Pricey, but likely very useful:

There's also: - but no touch. Available at

And the 4D available here (they also have an air pressure sensor):

With a GPS sensor, can get time & speed, with the speed and wind direction & wind speed, should be able to output real wind & apparent wind speeds and direction from the single anemometer sensor already mounted.

This guy has a lot of info:—serialgpsunit

Another possibility is hacking an Archos 5 or 7, since they run linux it should be possible to code normal apps for display- the issue is input, there's only one serial port, so some kind of NMEA multiplexer & converter to ethernet or USB might be better. They come with GPS and accelerometers and all kinds of capabilities built-in.

There's also Android based hardware,

Maybe a pitot tube can work accurately from 360 degrees? See below:

not suitable, but a good site:

Another thought- light-sensing for wind speed & direction? In that case no POT or essentially any connection to moving parts would be necessary. The moving parts would simply need to be free to move, and “reading” them would be a matter of sensors. Maybe CDS's to sense the position of the vane and the flashes of anemometer cups moving by? A single white LED could be used for constant illumination.

Android based stuff:
