I've made a board that makes this project particularly easy - it's the SkyTraq Venus838LPx-T breakout board product I sell on Tindie, but there's a new variant designed to be placed over the first 12 pins of the Raspberry Pi GPIO header. It connects...
The MalyanM200/Monoprice Mini has an interesting feature in that it supports wifi printing - the ability to connect Cura or something similar via wifi and print directly that way. This is accomplished via combination of features, starting with...
Having done a rough design of the MicroGrid Connection Unit, the next step was to build it on a breadboard and start writing some code. I decided to use a regular Arduino Nano for the first phase, in order to not risk breaking the Nano33 IoT. They are...
By whygee on Thursday 16 January 2020, 17:50 - Updates and news This is the last post of this blog on this platform. My hosting company discontinues its free blogging service so I have to move the archives to another place, probably http://yasep.org...
On a previous post I already discussed why I chose Labview to create a prototype. I like how it very quickly and easily allows you to create a prototype. I've installed the free (for non-commercial and non-academic) community version 2020. https://www.ni.com/en-gb/support/downloads/software-products/download.labview.html...
Bidirectional audio streams?Not sure how to implement bidirectional audio over BT with ESP32's single BT radio. ESP32 can be configured as an A2DP source or sink, but not both simultaneously, apparently. What I originally had mind was that...
I’ve written about the inverter’s transformer design and current management scheme in other logs so I figured I round it off with one on the gate drive and transistors.LayoutA big goal in this design was a reduced layout in terms of both physical space...
In this chapter I will show you the procedure to use OpenMV when we are going to test the machine learning model created with Edge Impulse on our Nicla Vision board. Build the Firmware Since the Nicla Vision doesn't have any on-board SRAM we need to...
Nesta última década assistiu-se a uma proliferação enorme de aparelhos eletroeletrônicos portáteis, tais como: brinquedos, jogos, relógios, lanternas, ferramentas elétricas, agendas eletrônicas, “walk-talks”,...
The Problem Well, that was a fun experiment, and I managed to get everything working; but, I had to remove COM from the BIOS. The problem was that, with MGIA video buffer spanning $10000-$13E7F, I only have 384 bytes for the BIOS to use between...
I calculated GimbalBot's center of mass and temporarily added a bright green disk to show its location on the model:I'm happy with that. During stabilization corrections, the craft will rotate roughly around that point. As was discussed at the beginning...
The final design will use the 100-pins Hirose FX8-100 connector. The PDF contains these pictures, to give you a rough idea :The stacking height is only 3mm between two boards. Actually it will vary because the PCB wil bend ;) but pairs of PCB can be...
I just released STM8EF v2.2.6 with some really nice features from the development branch:significantly more compact compiled user codeinterrupt code in Forth (thank Elliot for nagging me)simulated COM ports are no longer limited to Port D (but work with...
