2 min | 13919M5Stack has just launched the M5Stack CORE2, an ESP32 based IoT development kit, with a capacitive touch screen that brings users a smoother human-computer interaction experience. As usual, the development kit is compatible with Arduino, MicroPython, and UIFlow.
The M5Stack CORE2 has an ESP32 D0WDQ6-V3 with two Xtensa® 32-bit LX6 microprocessors that can be individually controlled. The clock frequency is adjustable from 80MHz to 240MHz.
M5Stack sent me an early sample to play...

Product Reviews, Raspberry Pi | 3 min | 5393
Last year, Elecrow sent me the CrowPi and I used it in some of my projects, including this video:
Together with the Corel USB accelerator, I programmed a YOLOv2 object detector, etc.
The CrowPi kit is magnificent and has everything you need to start playing with the Raspberry Pi. Furthermore, you get everything in a suitcase, that you can close and clean your "mess" in seconds. :)
Today, Elecrow is announcing a Kickstarter campaign to support the Crowpi2. This time, they integrated the Raspberry Pi in a notebook-like case (see fig. 1), and I think it i...

Last week, I've received a brand new M5Stack ATOM Echo parallel to the market launch (see Fig. 1). You might already know the M5Stack company. They make robust and open-source development kits with stackable modules. The kits allow you to make rapid and high-quality prototypes.
Today, the M5Stack launches the ATOM Echo. Check out this video, and see how it works with MicroPython:

3 min | 3193I've never used my blog to criticize a company. But this time, I need to express my complete disappointment with Gearbest. The last days, I have had the worst shipping experience, and I do have extensively worked with companies in and outside of the EU. In a nutshell, I ordered a home appliance on Feb. 21, and I'm still waiting to receive it. They've extended the shipping deadline twice (each time for one month), and now the tracking number has expired.

4 min | 5528Last month, I published a review of the DSO138. This time, I put together the WAVE2 (15801K) and I review it in this article. The WAVE2 is a 2-channel portable oscilloscope design by JYETech for a hobbyist. It has a resistive touch screen display, X-T (signal-time) / X-Y (signal-signal) plotting functionalities, memory (4 blocks), measurement functionalities (V -max, min, avr, pp, rms-, frequency, duty cycle), serial interface and can be powered using an external 5V source (micro ...

3 min | 9506A few months ago, I was looking for a small digital signal oscilloscope (DSO) module, and last week I got a DSO138 DIY kit from DigitSpace. The oscilloscope is originally from the company JYE Tech, but as usual, there are a lot of copies.
The oscilloscope has a bandwidth of 200kHz, a maximum sampling rate of 1MHz and a maximum input voltage of 50Vpk that are sufficient for the applications that I am programming using ESP32 boards (more details here).
In this article, I include a qui...

5 min | 15781This article evaluates three low budget Wi-Fi cameras that I buy from e.g. banggood.com and aliexpress.com but I will focus most of the analysis on my last acquisition the XIAOMI Mijia CMSXJ11A.
All cameras in this review are Xiaomi (not exactly built by Xiaomi) and can be connected to the application Mi Home (apple/android). Moreover, you need to select the region to China (Mainland) in the application, otherwise you are not going to find the devices. This has a main disa...

5 min | 8841Timeular is still on Summer Sale with up to 50% discount! Limited stock left, don’t miss out! First of all, this article is a product review which was/is not supported by Timeular GmbH or similar. I bought the product two weeks ago, because I wanted to test it. I missed out the Kickstarter campaign (2016) and the regular price for the octahedron was too expensive for me.

I've been very busy the last weeks. I moved to a new apartment and I was living between moving boxes. Four days ago, I managed to put my desk together and now I have some time (not a lot) to write a new article.
Last month I've received from GearBest two Aqara sensors:
- Aqara Cube - internal motion sensors (gyro + accelerometers)
- Aqara humidity, temperature and air pressure
These sensors use Zigbee and I connected them to a Raspberry Pi running Raspbian OS and a dockerized version o...
