MakerTronika Labs in Azerbaijan created this LoRaWAN capable dev board in Feather form factor:
Penguino Feather 4260 (SAMR34) LoRa Dev-Board
This is a SAMR34 based LoRa/LoRaWAN™ dev-board with all the necessary components for fast prototyping. It’s a successor of my previous Penguino SAMR34 design. The new design uses the RAK4260 module from @RAKWireless and improves on some aspects, such as a USB Type-C, a RGB LED, a user button, battery protection & voltage supervision, and optional flash & per-provisioned secure element IC pads.
Current HW version is v.1.2 and it’s offered in green soldermask (ENIG). All the design files can be found on my GitHub.
From v.1.2 onward the Penguino board also features CH340E USB-to-UART converter to further ease the development.
From Jo Hinchliffe on the Tindie blog:
Do you want your UAV to make amazing autonomous landings? This laser interface board from Avionics Anonymous may well be just what you need.
Laser range finders can be useful on UAV as altimeters and can make autonomous landings easier to perform. However adding a laser range finder to your UAV can be a little tricky. You might want the laser to be positioned far away from your flight controller, meaning you don’t want to use I2C, and you might not have a serial port to spare. This interface board uses the robust CAN bus using to connect a range of popular Lightware lasers to the common Pixhawk autopilots and others.
The laser altimeter is utilising UAVCAN which is an opensource, MIT licensed, lightweight protocol designed for resilient intra-vehicular communications. The CAN bus can also be used to re-flash the firmware meaning if you change out your laser model you can still use this board. Supplied preconfigured for a laser of your choosing, this adaptor board is compact, lightweight and has numerous screw mounts designed to be easily removed if space is short and you want to mount it directly with double sided tape.

Don’t Miss Out on the Best Virtual Hardware Conference of 2020!
Do you love everything hardware?! Then the 2020 Hackaday Remoticon has you covered this November!
Remoticon is a fully virtual hardware conference with 20+ workshops, 2 keynote talks, and 8 different demos. Join the weekend fun from wherever you are. Remoticon will have instructors teaching workshops from all across the globe, from Australia to India, from North America to the Netherlands.
Meeting virtually provides the perfect platform for more space, more people, and more options. Attend demos about Design Methodology, Robots, Zero to ASIC, Edge-Based Voice AI, and other awesome topics. Join workshops covering topics such as Reverse Engineering, Tiny ML, How to Hack a Car, Glowy Origami, and so many more.
In need of some creative inspiration and socialization with fellow hackers? Come hang out Friday night for a community Bring-A-Hack! There’s even a virtual Hackaday SMD Challenge for those who want to learn and those who want to put their skills to the test.
You’ll never guess the best part. I’m sure you’re thinking, “how could this get any better?” Remoticon Main Track tickets are free! You can also donate with a pay-as-you-wish ticket. Donations will go to charities that feed, house, or educate people.
Attendees only pay $10 to join a workshop. Some workshops do require hardware, which may include things you already have sitting on your workbench.
So the real question is what workshops and demos are you going to pack into your schedule the weekend of November 6-8th? We can’t wait to see you all there!
The MakersBox has a great kit for beginners on Tindie:
The perfect night-light, and a great way to learn how to solder.
The Joule Thief is a clever little circuit that can light a LED with a battery that is nearly dead. It does this with a pair of opposing magnetic fields. I like this circuit because it is simple to build, yet demonstrates some very complex electrical behavior.
I’ve designed a printed circuit board to help make this easier to build for beginning Makers. I used open source KiCAD software to lay it out (a future Instructable?), and OSHPark to manufacture it. If you want to just wire one up without the board, check out Angelo’s Instructable which uses essentially the same circuit.
The kit contains:
bobricius designed this low voltage step up converter module with white LED:
Features
- startup voltage 40mV
- requires only peltier element (not included)
- white LED
HOW IT WORK
- Peltier module generates very low electricity from temperature difference.
- Has two sides. If you keep COOL side (with aluminium cooler) at about 20 degrees and HOT side you heat with your body (fingers, forehead) with temperature etc 37 degrees you get about 40mV.
- This converter module increases this very low voltage to power white led.
Here is a video of the project:
From Jeremy S Cook on the Tindie blog:
With concerns about the transmission of COVID-19 at the forefront of society’s collective consciousness, UV light—especially the UV-C range—has been put forth as a possible solution. But how does one produce UV light indoors? UV LEDs of course!
For this purpose, prolific Tindarian Bobricius has come up with an LED module with a single 275nm UV-C light onboard. It includes the proper resistor to keep it functioning properly via a 9V power source, making it easy to implement.
While it may be effective, the listing notes that it is untested on viruses and bacteria. You’ll of course want to use it appropriately based on that information, and also note that it can be harmful to skin and eyes.
So why then did Bobricius make this contraption? As in so many works of science fiction, he had been dreaming of a radiation killing module. Now perhaps such a device can be used for good. Notably, there is a significant discount for orders of more than one, so perhaps a “killer array” would be a better option than a single source of radiation in this case!
Of course, makers aren’t just on the germ-offensive these days. As seen here, there’s been a huge push to produce PPE, especially during early shortages of a few months ago.
Soldering irons are a personal tool. Some folks need them on the cool side, and some like it hot. Getting it right takes some practice and experience, but when you find a tip and temp that works, you stick with it. [Riccardo Pittini] landed somewhere in the middle with his open-source soldering station, Soldering RT1. When you start it up, it asks what temperature you want, and it heats up. Easy-peasy. When you are ready to get fancy, you can plug in a second iron, run off a car battery, record preset temperatures, limit your duty-cycle, and open a serial connection.
The controller has an Arduino bootloader on a 32u4 processor, so it looks like a ProMicro to your computer. The system works with the RT series of Weller tips, which have a comprehensive lineup. [Riccardo] also recreated SMD tweezers, and you can find everything at his Tindie store.
Soldering has a way of bringing out opinions from novices to masters. If we could interview our younger selves, we’d have a few nuggets of wisdom for those know-it-alls. If ergonomics are your priority, check out TS100 3D-printed cases, which is an excellent iron, in our opinion.

We were exited to see this use of a flex PCB to create a backplane for the RC2014:
RC2014 is a simple 8 bit Z80 based modular computer originally built to run Microsoft BASIC. It is inspired by the home built computers of the late 70s and computer revolution of the early 80s. It is not a clone of anything specific, but there are suggestions of the ZX81, UK101, S100, Superboard II and Apple I in here. It nominally has 8K ROM, 32K RAM, runs at 7.3728MHz and communicates over serial at 115,200 baud.
