Resistors are one of the most common components you will come across in electronics. They are designed to lessen the amount of electricity along a particular path. A common use is to prevent LEDs from recieving too much voltage.

We made yet another weather station, this time uploading our own actual data to Dweet and Wunderground. Right now we only have temperature and humidity thanks to a SHT31 sensor. From this we also calculate dew point as well.

Please excuse the mess while we cleanup.
We have moved to a new platform and expect everything to be completed in a day or two.
All the same content and How To’s are here but you may find a stray bad link or two.
We hope two have this all cleaned up in a day or two.
We happened to find an old Zenith radio at a yard sale for not much money and decided to upgrade it, calling it Zen Radio.
We removed most of the insides but kept the speaker and all the controls.
Then we got to work on giving it an upgrade to play MP3 files.

A while back in NYC I spotted the Miffy Lamp in a store window. Miffy is a character created by Dutch artist Dick Bruna used in children’s books. Since the Miffy Lamp only used white colored LEDs, I decided to replace them with a Neopixel Ring. This ring has 12 RGB LEDs and sample code had me up and running in no time.

Making a stand alone Arduino is actually not all that hard. Five years ago I bought enough parts to make 10 of them. The reason for choosing 10 is that at most parts suppliers you get a discount for buying 10 or more of an item.
We followed this tutorial to make them and spent about $13 – $14 on each one, which was cheaper than buying an Arduino Uno at the time.
Now you can get an official Arduino Uno for $24.95 , so let’s see if making your own is still cheaper.

After going over our old weather station recently we discovered so many other good ones we thought we would round up a few. Once your station is all setup you can connect it to a service like the Weather Underground so you and others can see it online.
