In this post, I will show you how to flash a Sonoff Wi-Fi smart switch with the Tasmota firmware. Tasmoata is open source firmware for ESP chips. It gives you extra functionality like control via HTTP, Web UI, MQTT or serial compared to the Sonoff app. It also makes it easy to integrate with other services like Home Assistant. But most importantly it has no external dependencies and it won’t collect your data.
This is just a quick review of a couple of LED bulbs I got for my car some time ago. I want to share this so people don’t make the same mistake as I did buying these crappy LED bulbs. They were pretty cheap but even so it pointless buying them if they don’t work and just become e-waste. Also, it’s a pain to keep changing them when they die or start to flicker especially if they are in hard to reach places that require removing car parts to get to.
Recently I replaced/retrofitted the reverse lights and back fog lights on my car. I thought I’d document the process and post it online so it can help out anyone trying to do the same.
In this post, I will show you the contactless clamp power meter I made. I used a readily available SCT-013 current transformer clamp. The great thing about this is that you can measure the current flowing through a wire without having to put an amp meter in series with the load and source. This means you also don’t have to expose yourself to a potentially dangerous voltage.
In this post, I’ll show you how to do OTA(over the air updates) to your ESP32/ESP8266. This means that you don’t have to connect your ESP board to your PC by cable and can instead push firmware updates wirelessly over the network(as long as you are connected to the same network). The process of uploading the firmware remains almost the same. The only difference is you have to select a network port under Tools -> Port -> Network Ports instead of a COM port.
In this post, I will show the spot welder I made. A spot welder is a very useful tool that can weld two pieces of metal by simply pressing them together and passing a high current through that small point. This causes that particular spot where the metals are pressed together to heat up sufficiently to melt and fuse them together.
In this post, I’ll talk about the online GDS File Viewer/Editor I made(or I’m making as it’s still a work in progress). For now, I will make the development version of the app available online so people can find it and test it. Eventually, I will post the code on Github but first I want to add some more features, refactor the code and maybe write some unit tests.
In this post, I’ll show you how to program the Attiny microcontrollers via the Arduino IDE using an Arduino board as an ISP programmer.
In this post, I’ll show you how to program the ESP32 Camera board to live stream the video feed to your browser.
This tutorial will cover the hardware and software setup for the icestick development board that uses an iCE40 FPGA. The IceStorm open source toolchain will be used for programming the board instead of the vendor tools. For the demonstration, we’ll make a simple binary counter that will display its value with the onboard LEDs. The logic design will be defined/coded with Verilog.
