Maduino Lora(433M/868M)
Lora Solution Based on Arduino
https://hackaday.io/project/28981-maduino-lora433m868m
The LoRa Radio allows the user to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. The Maduino Lora useRFM95 and Atmega328, plus the power management circuit, to make it a ready-to-go solution for the Lora application.

Maduino Zero NFC
New Maduino Zero Series board with NFC
https://hackaday.io/project/168560-maduino-zero-nfc
Maduino Zero NFC is an Arduino-compatible small development board with NFC (Near-Field Communication). This board will be the bridge that helps you wirelessly interact with your environment, drive motors, unlock strikes, control relays, read from a temperature sensor, and all thanks to built-in NFC connectivity, right out of the box. Same other Maduino Zero boards, this board is based on ATSAMD21G18(which actually makes it available to work with MicroPython, if you re-program the bootloader)These days I am writing the user guide for this detailed usage for this module and should release it within this month.
Features:
1. Arduino compatible(with Arduino bootloader)
2. ATSAMD21G18, 32-Bit ARM Cortex M0+
3. Size: 40*55mm
4. Support Micro SD Card
5. 18* GPIO6. 13.56M wireless NFC
By the way, I am also planning to make it MicroPython compatible…:)

I BUILT AN ARDUINO POWERED COFFEE MACHINE | GAGGIUINO INSTALL ON GAGGIA CLASSIC PRO
https://www.youtube.com/watch?v=EJFadpL9aOE
This is a build log on how I turned my Gaggia Classic Pro (RI9380) into an Arduino powered coffee machine. This is a lengthy video so I’ve added timestamps below.
Thank you to Zer0-bit and the entire Gaggiuino community for all the work they put in to make this project possible. Check out the documentation below to see up to date information on how to build your own!

Build your own scratch DJ controller
https://cdm.link/2018/12/build-your-own-scratch-dj-controller/
https://djworx.com/step-aside-portablism-the-tiny-sc1000-is-here/
https://www.facebook.com/7portablescratcher/about/?ref=page_internal
If DJing originated in the creative miuse and appropriation of hardware, perhaps the next wave will come from DIYers inventing new approaches. No need to wait, anyway – you can try building this scratch controller yourself.
DJWORX has done some great ongoing coverage of Andy Tait aka Rasteri. You can read a complete overview of Andy’s SC1000, a Raspberry Pi-based project with metal touch platter:
Step aside portablism — the tiny SC1000 is here
In turn, there’s also that project’s cousin, the 7″ Portable Scratcher aka 7PS.
If you’re wondering what portablism is, that’s DJs carrying portable record players around. But maybe more to the point, if you can invent new gear that fits in a DJ booth, you can experiment with DJing in new ways. (Think how much current technique is really circumscribed by the feature set of CDJs, turntables, and fairly identical DJ software.)
Or to look at it another way, you can really treat the DJ device as a musical instrument – one you can still carry around easily.
The SC1000 in Rasteri’s capable hands is exciting just to behold:
Everything you need to build this yourself – or to discover the basis for other ideas – is up on GitHub:
https://github.com/rasteri/SC1000/
This is not a beginner project. But it’s not overwhelmingly complicated, either. Basically…
Ingredients:
Custom PCB
System-on-module (the brains of the operation)
SD card
Enclosure
Jog wheel with metal capacitive touch surface and magnet
Mini fader
Free software powers the actual DJing. (It’s based on xwax, open source Linux digital vinyl emulation, which we’ve seen as the basis of other DIY projects.)

Building a MIDI Controller Using Arduino

What do you do when you don’t have enough controls on your MIDI keyboard? You build a MIDI controller of course! Using an Arduino and some basic components this is an easier feat than you may imagine!

I built a MiniMOOG based Arduino DIY MIDI controller!
https://www.youtube.com/watch?v=aLhOO-UiMg4
In this video, I’ll show you the building process of the MidiMood, a Minimoog based DIY MIDI Controller, made with an Arduino!
The Minimoog is the most iconic analogue synthesizer of all times, with great plugin versions like the Arturia Mini V and the Moog’s Minimoog iPad app.
I always wanted to have better control over my synths and I thought that building a MIDI controller with the layout of the Minimoog was the best way to go. Although it is based on the Minimoog, it can be used with any virtual synth, like Massive, Omnisphere, Sylenth, etc.
This MIDI controller was made using an Arduino Pro Micro, and two multiplexers, besides the potentiometers and toggle switches.
The multiplexers allow me to increase the number of inputs of the Arduino, and the Pro Micro allows me to create a MIDI controller plug and play – MIDI class-compliant. All things that I teach how to do in the MMwA course.

Collin’s Lab: Guitar pedal hacking with Arduino
https://www.youtube.com/watch?v=_X0bL6WS-VY
Instead of chaining multiple guitar effects in search of a new sound, I decided to mod just one. Using an Arduino microcontroller board + digi-pot chip, I was able to add a variable gating effect to a fuzz pedal.

Plumbing Transformed Into Analog Inputs

Alastair Aitchison is an escape room designer. As such, he creates interactive puzzles that participants can solve to progress to the next stage of their quest. The challenge is that these puzzles need a rugged input, as they may take some abuse, and dealing with broken tech isn’t fun for anyone.

CLASSIC DOS GAMES ON AN ARDUINO?

It has been a while since we’ve seen a 86Duino, but [TheRasteri] reminded us about it, with his video showing how to use one to run classic MS-DOS games. To be fair, the computer isn’t really an Arduino, it’s essentially a tiny 486 PC on an Arduino-style PCB.
