A MightyOhm Geiger Counter samples radioactive decay from a martini glass that contains a small amount of uranium. If the number of clicks in a set period is even, the robot dispenses vermouth into the glass. If the count is odd, it dispenses gin, therefore creating a wet or dry martini based on the random process of radioactive decay.
Icarus has written a tutorial on connecting the MightyOhm Geiger Counter to an ESP8266 module and OLED display. His code (written in LUA for NodeMcu) is available on github. He is using the Wemos D1 mini board.
News flash –
As I mentioned on The Amp Hour, I’ll be traveling abroad for most of December. If you’d like to order a Geiger Counter or HV Rescue Shield, make sure to place your order by next Thursday, November 30th. I’ll update the shipping status page to reflect this.
If you are interested in purchasing a Geiger counter kit and miss the deadline, no worries! You can also purchase one from Adafruit.
Starting today I am now offering two shipping options for international customers – expedited and economy shipping.
As some folks are no doubt already aware, USPS Priority Mail International costs have more than doubled in the past few years.
Back in 2009 it cost about $12.95 to ship a USPS small flat rate box overseas. As of this year, the cost to ship that same small flat rate box is now over $30!
I’ve received feedback from several customers that the costs to ship overseas were too high, so I started looking at other options and found that USPS First-Class Package International offers slower delivery times (4-6 weeks) but costs less than half as much as USPS Priority Mail. In fact, the current USPS First-Class Package International rates are pretty close to what I was paying for Priority Mail when I first started selling kits. With this new economy shipping option, I can ship a single kit to Canada for $9.50 and to most of the rest of the world for $13.50.
I hope that the economy option appeals to overseas customers who are willing to wait a bit longer to receive their kit. For folks who are more impatient, I am still offering Expedited shipping (via USPS Priority Mail). For super time-critical orders I can also offer Express shipping on a case by case basis (please contact me before placing your order).
Important note: Regardless of shipping method, VAT taxes, duties, import tariffs, customs fees, etc. are always the responsibility of the buyer.
