Sending boards to fabrication in JLCPCB using their PCB Assembly service
In this entry we are going to add some instructive videos on how we prepare fabrication files in order to send them to fabrication in JLCPCB using their PCBA service. In this 3 videos I show what is my personal approach to prepare fabrication files to send a PCB design to JLCPCB. Including the BOM…

Making an epdiy v7 Kaleido clone – Routing – part II
In Part I of this series we described how to take an existing KiCad open source repository, fork it, and start making updates to customize the PCB.This PCB will be ultimately sent to fabrication using our trusted service of JLCPCB using their PCB Assembly service. My mission in this PCB project is to make a…

Making a epdiy v7 Kaleido clone – part I
In this post we are going to clone the epdiy v7 Hardware repository and make a custom version to control a Eink Kaleido 6 inches display.The existing epdiy v7 can control this epaper already but we want to make a PCB clone specifically for this display, removing other connectors and adding additional ones for Touch…

epdiy V7 S3 parallel epaper controller
I wanted to announce that the hardware for epdiy version 7, latest hardware for the project designed by Valentin Ronald, is ready to be tested. The original hardware you can find in the s3_lcd branch, this is my custom modified V7, that exposes 3 connectors: I’ve been testing also DES color epapers since I have…

New cases for the 9.7″ parallel displays and proposal for CLB Club
This might be a continuation from the Cinwrite DEXA epaper controller that we designed just after partnering with Freddie from Good-Display.comThe idea is to prepare an open source Firmware that is ready to be used with different examples and two target controllers: 1 – DEXA-C097 from Good-Display needs additionally my Cinwrite ESP32-S3 SPI controller Optionally…

Testing touch on small SPI epaper displays
Our now IDF ver. 5 compatible touch component FT6X36 is ready to be tested. There are two affordable models that I would like to cover in this post. First one is the 400×300 FT6336 from Good Display, we can see this one in action (2nd video, 1st had still wrong Waveform) It’s important to know…

Dust sensor data representation
The idea of using a HM3301 Laser dust sensor was to make a data representation that instead of boring numbers show a more visual appealing image representing particles and their size.For that we though about making a read each 2 minutes and use a bi-stable display with 4 grays.Components used: The build work!First you should…

Compiling an ARM Linux kernel with EBC eink interface
First of all the essentials which are clearly explained here: Build your first Linux kernel and make sure you have at least 8 GB free disk space .Please be aware that building your own Linux kernel needs to be done with care and it’s a risky operation where you might need to wipe everything if…

Making our own ESP32S3 BLE receive JPEG image Firmware
Since long I’ve been interested in using another means to receive binary data that are more low-consumption oriented than WiFi.And there is a protocol for that, which should be the standard, when sending and receiving BLE files. It’s called L2CAP: Logical Link Control and Adaptation Protocol: L2CAP permits higher-level protocols (such as GATT and SM)…

New Cinwrite SPI HAT for IT8951 parallel epaper controllers
At the moment only available in Tindie Fasani Corporation store this PCB mission is to provide: This Cinwrite PCB is open source Hardware that you can explore and even adapt to your needs. The price is 45 USD since I only made 5 and otherwise it will be impossible to cover the costs. But it…
