Rich Plakas has written a great tutorial on using the simple DHT22 temperature/humidity sensor with the Raspberry Pi in which he sends the readings to online IoT dashboard provider Initial State. He borrows a lot from other code (which he acknowledges) but the results are excellent and the sensor is relatively cheap (that’s just an Adafruit one; cheaper alternatives are available). Take a look at the tutorial here.

Gordon Hollingworth has just announced, over on the Raspberry Pi blog, that the Raspberry Pi 3 can be booted from USB mass storage devices. Information on how to do it, and which devices have been found (so far) to be compatible can be found on this page. Further boot modes, such as over Ethernet, will be explored in future blog posts.
This Saturday at Taunton Library, the first Raspberry Jam for the area will take place. Running from 10am-4pm, there will be Show and Tell and the following workshops:
You can get free tickets here and if you have any questions, please contact raspberrypijamtaunton@gmail.com.
Claire Garside is organising another Raspberry Jam for people in the Leeds area on Wednesday 7th September. The event, which runs from 6-8pm, features a workshop, some Show and Tell and time for a chat. The Jam is being held at Swallow Hill Community College and everyone is welcome, regardless of experience. Get your free tickets here.
You wait ages for an ROV powered by a Raspberry Pi and then two come along at once. Following on from Blue Robotics ROV the other day, the Foundation has blogged about OpenROV and their new Trident platform which has a Raspberry Pi 3 on board. Take a look here.
Following yesterday’s news that The Pi Podcast has come to an end, I’ve been keeping an eye out for a replacement. Well, the first one has appeared! Young Josh has just started a series of podcasts based on his visits to the long-running Preston Raspberry Jam. He’s conducted two interviews so far: one with hobbyist Jacob White and one with David Ferguson, creator of Pi Bakery which is something I haven’t come across before. Pictured below, it appears to be an easy way to configure various things on your SD card before you insert it into your Pi. Terrific stuff.
Anyway, you can hear Josh’s two podcasts on SoundCloud. You can also visit his website which is called “All About Code” here. There are some great resources on there, including some which are aimed at SEN children using the CamJam EduKit. Well worth a look. If you want to chat to Josh, he’s on Twitter.
