Hackaday Links: December 8, 2019
Now that November of 2019 has passed, it’s a shame that some of the predictions made in Blade Runner for this future haven’t yet come true. Oh sure, 109 million people living in Los Angeles would be fun and all, but until we get our flying cars, we’ll just have …read more

Bee Minder Proves Not Even Bees are Safe From Surveillance States
We all know how important bees are to our ecosystems and [Kris Winer]’s bee monitor provides a great way to monitor these amazing but delicate creature’s habitats, hopefully alerting us before a disaster strikes a vital hive.
The board is based around LoRa sensor tile called Cicada but redesigned to …read more

Modular Camera Remote Is Highly Capable
Many cameras these days have optional remotes that allow the shutter release to be triggered wirelessly. Despite this, [Foaly] desired more range, and more options for dealing with several cameras at once. As you’d expect, hacking ensued.
The system goes by the name of Silver, and is modular in nature. …read more
Hackaday Links: August 4, 2019
Is the hacking community facing a HOPEless future? It may well be, if this report from 2600 Magazine is any indication. The biennial “Hackers On Planet Earth” conference is in serious financial jeopardy after the venue that’s hosted it for years, the Hotel Pennsylvania in Manhattan, announced a three-fold increase …read more

High-Tech Alms Collection With The ESP32
In an ideal world, shop space, tools, and components would be free. But until we get to that Star Trek utopia, hackerspaces will have to rely on donations from the community to help stay afloat. While asking for money, at least you can have some fun with it if you …read more

Storm Chasers Score Bullseye On Tornado With Instrument-Packed Rocket
Model rockets are a heck of a lot of fun, and not a few careers in science and engineering were jump-started by the thrilling woosh and rotten-egg stench of an Estes rocket launch. Adding simple instrumentation to the rocket doubles the fun by allowing telemetry to be sent back, or …read more

Custom LoRa Pager Designed With Care
LoRa is a useful technology if you need to send data a long way at low power levels. Leveraging this, [5Volt-Junkie] decided to build a small pager named the LoRaNicator.
Those who love a detailed build log will enjoy this. The pager features everything up to and including the kitchen …read more

DIY Mini Helical Antennas From Salvaged Co-ax Cable
[Mare] has a visual guide and simple instructions for making DIY mini helical 868 MHz antennas for LoRa applications. 868 MHz is a license-free band in Europe, and this method yields a perfectly serviceable antenna that’s useful where space is constrained.
The process is simple and well-documented, but as usual with antenna design it requires attention to detail. Wire for the antenna is silver-plated copper, salvaged from the core of RG214U coaxial cable. After straightening, the wire is wound tightly around a 5 mm core. 7 turns are each carefully spaced 2 mm apart. After that, it’s just a matter …read more
Vinduino Water-Smart Farming – Now with LoRa!
Our five rounds of Hackaday Prize 2018 challenges have just wrapped up, and we’re looking forward to see where the chips fall in the final ranking. While we’re waiting for the winners to be announced at Hackaday Superconference, it’s fun to take a look back at one of our past winners. Watch [Reinier van der Lee] give the latest updates on his Vinduino project (video also embedded after the break) to a Hackaday Los Angeles meetup earlier this year.
Vinduino started with [Reinier]’s desire to better understand what happens to irrigation water under the surface, measuring soil moisture at different …read more

Putting M5Stack on LoRa and the Things Network
LoRa is the new hotness in low-power, long-range communications. Wanting to let the packets fly, [Xose] was faced with a frequecny problem and ended up developing a Europe-friendly LoRa module for the M5Stack system. The hardware is aimed at getting onto The Things Network, a LoRa based network that provides connectivity for IoT devices. While there was an existing M5Stack module for LoRa, it only supported 433 MHz. Since [Xose] is in Europe, an 868 MHz or 915 MHz radio was needed. To solve this, a custom board was built to connect the HopeRF RFM69 series of modules to the …read more
