Arduino Strain Relief Enclosure

https://create.arduino.cc/projecthub/JeremySCook/arduino-strain-relief-enclosure-97c6fd?ref=user&ref_id=97062&offset=0  Arduino boards are great for experimentation. You just plug the wires in, and the connections stay there with spring force. On the other hand, they also pull out quite easily… Here is An enclosure for the Arduino Uno that not only allows you to see inside, but locks down wires coming out to keep them

Store Your Sensitive Data Safely When Sharing a Sketch – Arduino Project Hub

https://create.arduino.cc/projecthub/Arduino_Genuino/store-your-sensitive-data-safely-when-sharing-a-sketch-e7d0f0?ref=platform&ref_id=424_recent___&offset=0 Often in your sketch, there is some sensitive data that you’d like to keep private, which could accidentally become public when published on GitHub or when you share your sketch with someone else via URL.This sensitive information may include Wi-Fi network names and passwords, API key, and so on. But now, you can add a

Arduino Widens Wireless Offerings with Two New Boards

https://makezine.com/2017/09/23/arduino-widens-wireless-offerings-two-new-boards/ There are now two new Arduino boards, the long-range radio (LoRa)-equipped MKR WAN 1300 and the cellular-capable MKR GSM 1400. The boards come in with the MKR form factor that Arduino has been utilizing of late, measuring 67.64 x 25mm. The company says they also offer low power consumption, making them useful for IoT applications such

DIY optical power meter with SFP module and Arduino idea

Fifer optics power meter is an important tool for debugging fiber optics networks. I have earlier tested a cheap commercial fiber optic power meter a at Fiber optics power meter posting. Hardware hackers ares famous for building their own test equipment. The basic operation of optical power meter is quite simple: take a suitable detector,

Arduino serial plotter

I just found out a new useful Arduino IDE feature: Serial Plotter. It allows you to natively graph serial data from your Arduino to your computer in real time (no need for extra software for that).The Arduino Serial Plotter function has been added to the Arduino IDE since version 1.6.7. Here is introduction video on

How to build your own DIY makeshift levitation machine at home • The Register

https://www.theregister.co.uk/2017/08/16/engineers_show_how_to_construct_makeshift_acoustic_levitator/ Engineers at the University of Bristol in the UK have published a rough guide to building a simple levitation chamber that uses sound waves to suspend objects. A paper published in the Review of Scientific Instruments this month shows how it can be done within the confines of your own home lab. Using a 3D printer,

Web-Based Universal Remote for Under $4 (Probably) – Hackster.io

https://www.hackster.io/user70641842/web-based-universal-remote-for-under-4-probably-e9e929?ref=explore&ref_id=trending___&offset=4 Don’t buy a universal remote, make one. It’s cheaper, funner, universal-er, kind of, and you get to learn the ESP8266, kind of. You will need the Arduino IDE with whatever OS. Alternatively Linux and some C skills for the official Espressif stuff, but that’s unnecessarily challenging for this application. To get IR control codes

Visual Development with XOD

https://hackaday.com/2017/08/13/visual-development-with-xod/ This looks interesting:  If you program microcontrollers like the Arduino, you should check out XOD and see how you like visually creating software. The software is open source and currently, can target the Arduino or Raspberry Pi. Some alternative visual programming tools: – LabVIEW RT or Matlab Simulink – both very powerful, very stable, closed source
