If you’ve ever worked on a small PCB, you know how much of a hassle it can be to hold on to the thing. It’s almost as if they weren’t designed to be held in the grubby mitts of a human. As designs have become miniaturized over time, PCBs are often so fragile and festooned…
Hey guys! In this tutorial we’ll be creating a GPS tracker using the Botletics SIM7000 LTE shield and an Arduino and view the data on two free IoT dashboards. I’ll start off by explaining how to get everything set up and posting data to the cloud, then I’ll move into how to set up the IoT dashboards to view data. The two dashboards we will be looking at are Freeboard.io and ThingsBoard.io.
Since this tutorial is a follow-up of my first Instructable on using the Botletics LTE/NB-IoT shield for Arduino so if you haven’t already, please read it to get a good overview of how to use the shield and what it’s all about. In this tutorial I’ll focus on IoT data logging, and specifically, GPS and temperature tracking and provide you will all the code and guidance you’ll need to hit the road and test it out! It’ll be a decently lengthy tutorial so sit tight and grab some coffee!
Although I’ll be mainly focusing on the LTE shield that I personally designed and built, everything here (including the Github Arduino library) should work on SIMCom’s 2G and 3G modules like the SIM800/808/900/5320 as well since it’s just an updated version of the Adafruit FONA library. Regardless of hardware the concept is exactly the same and you can do lots of cool stuff with this, including sensor data logging, remote weather monitoring, auto theft karma GPS tracking, etc… so read on!
When we think of building research hardware, lab coats and pristine workbenches come to mind. Shah Selbe used to do something kind of like that when he was engineering satellite propulsion systems. But after putting twelve of them into space, he ditched the office gig and took his gear to some of the wildest places on…

When it comes to finding what direction a radio signal is coming from, the best and cheapest way to accomplish the task is usually a Yagi and getting dizzy. There are other methods, and at Shmoocon this last weekend, [Michael Ossmann] and [Schuyler St. Leger] demonstrated pseudo-doppler direction finding using cheap, off-the-shelf software defined radio…

This is a meetup of a few hours organized in the context of the Open Source Body week in La Paillase, Makery and Gaite Lyrique, about the interface of Open Hardware and Health.
We would like to invite all CRI researchers, students, or staff and other external guest to meet and discuss with Alexey Zaytsev, hardware designer based in Shenzhen, China; André Maia Chagas, part of the initiative TREND in Africa and creator of Flypi, a 100€ fluorescence microscope; and Guy Aildeberg, PhD student in CRI, developing a low cost DNA detection kit. We will know more about their projects, meet each other over a glass of wine or juice, and discuss about personal cases and general trends in this field.
Do you like Science, Technology, Art, and Hacking? SparkleCon is this weekend at 23b hackerspace in the Los Angeles area:
SparkleCon is a two day event where people from all walks of life come to share and participate in art, science, computers, security, and hacking. It has been hosted at 23b Hackerspace since 2013 and as attendance has grown over the years so has the extremeness of the events contents. Come and enjoy things like 3D body scanning, lock picking, coding, 3D printing, large Tesla coils, and nuclear fusion.
Join Drew Fustini, Chris Gammell, Andrew Sowa and more tomorrow night, Tuesday, January 23rd, in Chicago for Hardware Happy Hour (3H) at mHub:

Looking for a ultra tiny development board? Tomu is an ARM Cortex M0+ device that fits inside your USB port. We’ve seen these in person, and they’re tiny. There’s a few commercial devices in this form factor on the market. For example, the Yubikey Nano emulates a keyboard to provide codes for two-factor authentication. The…
