Electronic, 3D printing and embedded programming
To help with fast prototyping, I’m going to create a set of shields for the WeMos D1 mini. The shield of this article manages the EBYTE LoRa device (E22, E32 and E220) with HardwareSerial, already exists a variant with SoftwareSerial.
To help fast prototyping I’m going to create a set of shield for WeMos D1 mini, the shield manage a 3.3v relay with configurable pins
For fast prototyping, I will create a set of shields for the WeMos D1 mini; the first is a service board with integrated pcf8574 IC, an encoder, and five other pins to use as input or output.
After carrying out all the calibrations, all that remains is milling our piece. If the whole process is successful, I expect an excellent final product.
One of the most important features is the auto-level. Even if your CNC is precise, it will never be accurate to one-hundredth of a millimeter, but to carry out the removal of copper, you will have to have an excellent level of precision.
Here we are going to learn how to do auto-level.
I have been prototyping PCBs with the CNC for years. I have created a CNC machine suitable for this, and today I would not know how to do it without it.
I have been using bCNC for some time as a GCode sender, a very simple open-source software, we will see how to install it and do the probe.
I want to modify the WiFi module firmware of my FlyingBear Ghost 5 to support the Web Socket protocol and I want to develop the web interface as well.
Here I’d like to explain what is the MKS WiFi module how to program and how to connect a device that can be used like WiFi module alternative.
In this article I would like to show my custom PCB for the Ciclop 3D scanner which is fully compatible with the original ZUM.
I’m going to use the esp32, and the first problem was how to put It on breadboard, so we are going to print an adapter, then I build a PCB to program.
When I went to use esp12 and esp07, and the first problem was how to put it on the breadboard, luckily I found an adapter developed by tweeto, and that was what I needed, but I would like to make it easier to use, so I redesigned it smaller and added some labels to identify the pins, than I create a PCB to use It as programming board.
