From Ken Olsen of The Maker’s Box:
You never know what people will do with your ideas, and it is always fun to see someone do something I would have never thought off with them. I got a video from someone who built my Programmable Fidget Spinner, and used a leaf blower to see how fast they could get it to go. Fortunately, they were wearing safety glasses, and no, it didn’t come flying apart. It did, however, start displaying erratically at about 3600 RPM (the fastest I can get it by hand is just under 2000 RPM).
So, what is going on? TLDR: I figured it out and fixed it, and here is proof.
Timothy Woo has launched a Indiegogo campaign to manufacture his open-source, Arduino-compatible, wireless PCB reflow oven controller:
Reflowduino is the first completely open-source, Arduino-compatible reflow oven controller of its kind that enables practically anyone to assemble their own beautiful circuit boards at home!
Reflowduino comes loaded with features, all in a compact Arduino-compatible package, with full documentation, example code, demo app, and comprehensive wiki on Github.
Reflowduino is designed to be extremely easy to use! The general concept is to switch the power of the appliance on or off with a solid-state relay as shown below, measuring the temperature by placing the thermocouple tip inside the oven during the whole process.
If nothing else, please share this campaign to your friends, family, and anyone who might be interested on social media! Remember that every view counts for me, and I’m depending on you to make this happen!
From Timothy Woo on Hackaday.io:
This open-source LTE shield uses SIMCOM’s SIM7000-series modules with the latest LTE CAT-M technology to allow Arduino users to painlessly connect their low-power IoT devices with the next-generation cellular technology!
NB-IoT is also available for many countries (but sadly not in the USA yet) simply by swapping out to a different SIM7000 module version. Luckily SIMCOM made it super easy to integrate this module because most of the AT commands are identical to previous version, and Adafruit has a wonderful library for their FONA 2G and 3G products. Check it out and help make this happen!
You can view the latest code and design files here on my Github page: https://github.com/botletics/NB-IoT-Shield. Note: The hardware works great but software is still under development! I plan on launching an Indiegogo campaign when I get a fully-working prototype, so stay tuned for updates!
From Jeremy S. Cook on the Tindie blog:
Thermal imaging has remained an interesting, if costly, technology for some time. One lower cost option is the the Grid-EYE sensor from Panasonic. While it has a resolution of only 8×8 pixels, it’s priced in the low double digit range, making it an ideal candidate for budget projects. If you’d like to add it to your build, Pesky Products has a has a breakout available that allows it to be used with the I²C protocol.
Xose Pérez, after finding this sensor and breakout on Tindie, which he (correctly) considers “a great place to find uncommon electronic components or weird/interesting boards,” decided to make his own low-resolution IR camera. At only 64 pixels of resolution, it’s not as capable as more expensive units, but it could still be very useful for getting a general idea of what is hot and cold in a room/environment. The case is made out of slices of acrylic, paper, cardboard, and MDF, giving it a very unique look. It also features a small screen to display supplemental information, and a simple button/switch interface.
