low.js: Review of (the last months of) the year 2020

2020 is almost over, and before it is, we would like to give a sign of life here before 2021 arrives and give some insights what is happening at neonious for everyone who is interested to know. What’s this about? As you might know, we develop low.js, an Open Sourced port of Node.JS for ESP32…

Created ESP32-WROVER-EVB based on Open Sourced Olimex ESP32-EVB: Ethernet, MicroSD, IR, Relays, CAN, UEXT, and now 16 MB Flash/4 MB RAM for low.js or MicroPython

Our Open Source framework low.js is a port of Node.JS for ESP32 based microcontrollers. With low.js we are bringing ease of programming, scalability of programs and easy connectability to the Internet on to small devices. The ESP32 is a great target, because it is powerful, yet low cost. It provides Wifi out-of-the-box, also Ethernet jack support,…

Built a RC car which can be controlled by touch using a cell phone.

Built with some electronics and programmed with just a few lines of JavaScript code. How it was done: The hardware I took an off-the-shelf RC car. I removed the chassis and threw away the electronics board inside. I kept the bottom frame with the battery compartment, the motor and the wheels. The steering was done…

Achieve Great Results Easily with neonious one

We created a short video highlighting what can be done with low.js, and the neonious one board in particular. It shows off the IDE, the debugger, but also shows how npm modules can be installed from the graphical npm package manager to quickly achieve great results. To be more precise: In the example the module…

ESP32-WROVER is fundamentally broken (but is being fixed by Espressif now)

Update 01/29/2019: Espressif confirmed they are working on a fix in a comment to the GitHub issue today. Update 02/20/2019: Because this issue is not resolved yet, current versions of low.js for ESP32 only use one core, as this problem does not arise then. This usually does not slow down the JavaScript program, because JavaScript…

Faster, optimized ESP-IDF fork + PSRAM Issues

Side note: I am writing from the 35th Chaos Communication Congress, in Leipzig, Germany. If anyone is here and wants to chat about low.js, neonious one or JavaScript, Node.JS, ESP32 or microcontrollers in general, please get in contact. During the development of low.js, a Node.JS port for ESP32 boards, we had a few challenges to…

Welcome to our new blog!

The primary reason for this blog is to transfer our knowledge about electronics and IoT to people reading this blog. Hopefully we can spark many people’s interest in these things and maybe some interesting projects will result out of this. Apart from this we will also use this blog to write about interesting things happening…
