The Color Kit Grande is the latest update of the hardware kits which I started selling back in 2015. It started with the ESP8266 and a tiny B/W OLED display. A little later the ESP8266 Color Kit followed and added a bigger display with resistive touch screen to it. Buyers also had to do a bit of soldering to complete the kit.
perience of setting up an inexpensive room sensor network using an ESP32 and a couple of Xiaomi devices, with the help of the open source project OpenMQTTGateway.
I mostly use EasyEDA for PCB design: it is easy to use and ordering assembled PCBs from JLCPCB couldn’t be easier (and cheaper) with any other EDA tool. But exporting your PCB design from EasyEDA as a 3D object is really faulty. Often we want …
If you are still looking for justifications to buy a 3D printer then this blog post is for you. Banggood recently sent me the Ender 3 V2 for review and wow, this is really a great printer! I had two other printers before but this …
Logic Analyzers can be quite useful to test and analyze hardware. In this short video I explain how to use the cheap LHT00SU1 logic analyzer together with PulseView on Mac OS X to test a new ESP32 development board.
How do you add new virtual devices/commands in Node-Red so that Alexa can control them? There are great Node-Red extensions but things get more complicated if Node-Red is running in a docker container. In this blog post I share my take-aways from setting this up.
The ESP32 platform offers a wide range of functionality almost out of the box. For instance you can turn a ESP32 with little effort into a Bluetooth Audio speaker. In this article I describing how I tapped into the digital data stream coming from a …
Fritzing is a wonderful tool to document your electronic projects, if – and only if – the parts you use are available in the parts library. If you are designing parts yourself you can help the community by creating Fritzing parts for your designs.
The ESP32 is a remarkable chip. It has many peripherals, lots of processing power. With built-in WiFi und BLE support it offers two widely adopted communication protocols. And with the right circuitry and programming it can ran from batteries for a very long time. In …
For a long time I had a 8×8 RGB WS2812 led module in my gadget box. The WS2812 led is a wonderful component for makers. It is easy to program and comes in many forms for a really low price. With just 3 lines (5V, …
I love machines that help me to build my projects. I also love to hack devices to do more than they were built for. So you can imagine what a fun project it was for me to hack my desktop 3018 CNC mill into a …
Recently I was asked: “What do you need a development board for?” For me the answer is very clear. I love short development cycles. It’s much faster to verify an idea on a bread board before you sit down and design a PCB. Designing a …
For a long while now I was always looking for a development board that would help me to create battery-driven IoT projects. Since I couldn’t find it we decided to design one and sell it with ThingPulse. It only consumes between 25-35uA and accepts a …
Until recently I believed that having PCBs assembled by a professional service is either too costly for small batches or not possible at all. That was until I realized that some PCB manufacturers offer an additional assembly service (PCBA) and that their minimum order quantity …
My family and I live in an apartment building and the laundry machine and the tumble dryer are in the basement. In the past, it happened many times that I went down to take out the laundry just to realize that the machine was still …
This post shows how to use a I2S microphone with the ESP32 to show graphical representation of the recroded frequencies
Recently a new class of 3D printers has become affordable for hobbyists: several Stereo Lithography (SLA) printers are now available for prices below USD $600. These devices can produce prints with very different properties compared to the well know Fused Deposition Modeling printers (FDM). I’ve …
I’m constantly adding new features to my Tevo Tarantula printer. The latest addition is a bed leveling sensor.
In the last few years blog.squix.org has grown from a personal idea dumping ground to a well visited page around maker projects. Two years ago I started looking for a way to make it easier for you to rebuild my projects. The first step was to provide links …
In the first blog post blog post in this series I showed you how can configure the Seeeduino LoRaWAN module to connect it to TheThingsNetwork (TTN). The second post showed you how the LoRaWAN message can be sent to a Google Spreadsheet. Now this post goes one …
With the last production batch we secretly updated the ESP8266 WeatherStation Color Kit. First change is the increased size of the custom PCB, which now has the same size as the TFT board. We also added holes and two spacers and female headers so that …
Do you have these moments when you start to realize that something you just created is gonna be a game changer, at least for you but maybe also for others? Last week I had such a moment when I decided to follow up on an …
In the following video I explain the new web interface for configuring the ESPaper WeatherStation application. This allows you to change WiFi or location settings without reprogramming the ESPaper The ESPaper Plus Kit is available from the Squix Shop
I am very happy to announce that the 2.9″ ESPaper module is now ready for your pre-orders in two versions.
Hi Sergey, thank you so much much for agreeing to this interview! Can you tell us a bit about your role at Mongoose OS? I am a technical cofounder and CTO of a company behind Mongoose OS, and set the overall technical direction for the …
Are you also curious to learn a bit more what is going on behind the scenes at Espressif, the company manufacturing the ESP8266 and ESP32 chips? My friend Marcel Stör (frightanic.com) and I compiled a list of questions to Ivan Grokhotkov (@i_grr), Director of Software …
After many hours of work I’m very happy to finally publish all the sources for the ESP8266 PlaneSpotter project. It is not yet really in a V1.0.0 state but I’m sure with the help of the community it will quickly get better. While this post is …
