It works with some missing features, but it breaks after 2 years of use. https://martijnvwezel.com/blogs/watersensor_sensor_based/ Wed, 03 Jan 2024 00:00:00 +0000 https://martijnvwezel.com/blogs/watersensor_sensor_based/ Webshop The Muino water approach for water usage sensors aims to simplify installation by reducing complexity. Unlike traditional inductive sensors, the new design is smaller and easier to place, with a more intuitive interface. https://martijnvwezel.com/blogs/watermeter_working_basics/ Sun, 19 Nov 2023 00:00:00 +0000 https://martijnvwezel.com/blogs/watermeter_working_basics/ Visit Tindie webshop I frequently receive inquiries about how my sensor works and why it’s more affordable and less bulky compared to others. People often ask if it can be used on their water meters. https://martijnvwezel.com/blogs/watermeter_werking_basics/ Sun, 19 Nov 2023 00:00:00 +0000 https://martijnvwezel.com/blogs/watermeter_werking_basics/ Bezoek Tindie-webshop Ik krijg vaak de vraag hoe mijn sensor werkt en waarom deze veel goedkoper en minder omvangrijk is. Mensen vragen zich ook af of deze sensor op hun watermeter kan worden gebruikt. https://martijnvwezel.com/blogs/watermeter_status/ Sat, 04 Nov 2023 00:00:00 +0000 https://martijnvwezel.com/blogs/watermeter_status/ The Muino water approach for water usage sensors aims to simplify installation by reducing complexity.

However, currently, there is no open-source board that can function as a general-purpose programmer with OpenOCD for Raspberry Pi. https://martijnvwezel.com/blogs/esp32_heatcamera/ Sat, 21 Jan 2023 00:00:00 +0000 https://martijnvwezel.com/blogs/esp32_heatcamera/ Gas prices soared when Putin entered Ukraine, causing homeowners to seek ways to lower their monthly energy bills. I found myself with some spare chip sensors, including the MLX90640 and an ESP32-C3 (RISC) WiFi chip. https://martijnvwezel.com/blogs/startup_investing_in_crypto/ Mon, 22 Aug 2022 00:00:00 +0000 https://martijnvwezel.com/blogs/startup_investing_in_crypto/ A well-funded company named “Pixie” wanted to build a Viking game with NFT game characters. I was excited about the idea, but it is bankrupt because of bad management and investing 800K of its funding in Luna, which crashed big time after this investment. https://martijnvwezel.com/blogs/smartconnect/ Sat, 11 Dec 2021 00:00:00 +0000 https://martijnvwezel.com/blogs/smartconnect/ Link to Github project, will be soon added It is almost Christmas and it is darker outside, so I added some lights in the loft. The chosen lights are the crappy ‘LSC smart connect’ light. https://martijnvwezel.com/about/ Wed, 04 Nov 2020 00:00:00 +0000 https://martijnvwezel.com/about/ My journey began with a passion for Mechatronics, which led me to pursue a degree at The Hague Applied Sciences with a specific focus on machine learning, robotics, and computer vision. https://martijnvwezel.com/blogs/master_thesis/ Fri, 30 Oct 2020 00:00:00 +0000 https://martijnvwezel.com/blogs/master_thesis/ A robust modular spiking neural networks training methodology for time-series datasets Link to part of my thesis With a focus on gesture control Neurons in Spiking Neural Networks (SNNs) communicate through spikes, similar to the way that neurons in the brain communicate, thus mimicking the brain. https://martijnvwezel.com/blogs/ikea_smarthome_garbage/ Mon, 27 Apr 2020 00:00:00 +0000 https://martijnvwezel.com/blogs/ikea_smarthome_garbage/ Ikea sells goods that are in some cases cheap, but you would think if they would design some low-power electronics they would make mistakes that could burn down your house. Actually, this almost happened with the Ikea TRÅDFRI Gateway. https://martijnvwezel.com/blogs/ms_word_crash/ Sat, 28 Mar 2020 00:00:00 +0000 https://martijnvwezel.com/blogs/ms_word_crash/ Believe it or not, shit tool. If you search for “The page cannot be found” or “Missing file” or something in a different language like “Fout ! Bladwijzer niet gedefineerd”. You will find a lot of Microsoft help-pages that contains no fix. https://martijnvwezel.com/blogs/spiking_neural_networks/ Mon, 17 Feb 2020 00:00:00 +0000 https://martijnvwezel.com/blogs/spiking_neural_networks/ What are spiking neural networks, and why are they the future? Spiking Neural Network (SNN) can be seen as small tiny networks that mimic the brain. In our brain, the neurons talk with each other through spikes. https://martijnvwezel.com/projects/muino/ Wed, 16 Oct 2019 00:00:00 +0000 https://martijnvwezel.com/projects/muino/ Hate to website engineering At the first glims of what I heard and saw about websites was that it is boring and not useful. This changed when I worked at a company for wireless sensor networks. https://martijnvwezel.com/blogs/papernccv19/ Wed, 16 Oct 2019 00:00:00 +0000 https://martijnvwezel.com/blogs/papernccv19/ The following paper is a follow-up from the deep learning course at the TU Delft with Prof J. van Gemert. There was a project to be made, this had some success, and after some hard work due the summer holiday, it was accepted by the NCCV 2019. https://martijnvwezel.com/blogs/smartconnect/log1/ Mon, 01 Jan 0001 00:00:00 +0000 https://martijnvwezel.com/blogs/smartconnect/log1/ This log is after boot proceder.

Using the power from the adapter the MCU sock gets 3.3V and therefore. The full output of the log is showed. From the logs its clear that the company tuya are the PCB designers and also the software developers. https://martijnvwezel.com/blogs/smartconnect/log3/ Mon, 01 Jan 0001 00:00:00 +0000 https://martijnvwezel.com/blogs/smartconnect/log3/ PS C:\Users\marti> plink -serial COM15 -sercfg 115200,8,1,n,n [01-01 01:01:46 TUYA Notice][uni_work_queue.c:146] work_queue add task:423d80 [01-01 01:01:46 TUYA Notice][uni_work_queue.c:146] work_queue add task:423d80 [01-01 01:01:46 TUYA Notice][uni_work_queue.c:146] work_queue add task:423d80 [01-01 01:01:46 TUYA Notice][uni_work_queue. https://martijnvwezel.com/blogs/port_forwarding/ Mon, 01 Jan 0001 00:00:00 +0000 https://martijnvwezel.com/blogs/port_forwarding/ Forward port to another server [L] TODO ssh -L 8081:localhost:8080 example.com Get a port from another server and connect it locally [R] 22: ssh port of the machine example.com 8081: Using this port on the localmachine you can ssh from your local pc; ssh -p 8081 example.
