  • Not only will this affect prices for hobbyists, but also for those looking into dipping their feet into the hobby. Popular kits like the Arduino pkg and littleBits could be more cost-prohibitive. I'm starting a weekly electronics workshop with a curious 7-y.o. and his mother is somewhat nervous about safety and how long he will be interested, so I'm taking the baby steps with components I have before we see what he really wants to play with and avoid spending more money than necessary. Parents without this advice could look at an electronic kit after the new tariff and not be interested in getting it nor interested in taking the time to look into smaller kits (Radio Shack would've been wonderful for checking out small kits).

  • I live in Philly, PA and the hackerspace (hive76) moved further away, so it's no longer practical for me to go there routinely. As for gender divide, I think it's a matter of time. There are a lot of females showing, for example, RPi projects and making great videos, so that momentum needs to keep going.

  • "A resistor, a capacitor, and a transistor walk into a bar...I love that joke!"

  • I totally agree with improving visibility stylishly. Other arrangements of the LED string would be to put the string in the mid-section of the scarf (so it's not on the edge close to your eyes) or around the edges of a comfortable vest you can wear over a sweater.

  • I've been inspired by the Tetra Society where people volunteer to build devices for those who can't afford them. http://www.tetrasociety.org/about/index.php When I have more time, it will be one group I will look into joining.

  • Interesting sensor. I wonder how the VOC readings would compare to those of the Grove gas sensors by Seeedstudio or Adafruit's MiCS5524 gas sensor. It's nice to have many options.

  • I really can't fathom dealing with electronics so close to wastewater. Even dealing with Saran wrap (which will eventually tear) will be messy. Every flush produces an aerosol near the toilet. I prefer the idea of a PIR attached to a couple of semi-bright colored LEDs posted above, behind, or to the side of the toilet so there's enough illumination to see around without bright light. Since my master bathroom is a three feet away from my bed, this is a must-try to avoid waking up my partner.

  • Has this been tested to see how long it can withstand high humidity assuming you somehow protect the Arduino?

  • I built a battery-powered soil sensor using a UNO, soil sensor, and 9V battery connector. As shared by others, the soil sensor can't be left in soil for very long. A servo-actuated mechanism to lower the sensor periodically would be useful. I noticed that the soil has to be quite dry to lower the output considerably and it may be too dry for plants even though it feels moist to the touch. I'll have to play around with fine-tuning thresholds. Could be a good science fair project for students.

  • Suggestion; when assembling something that involves a screen, I would take the protective film off last to minimize scratching until turned on.

No public wish lists :(
