Hi, I know the very basics of Blender, but I'm stuck on a certain tutorial: I need a recorded video example/video explanation that clearly shows me the steps in this tutorial so that I can get to the same end result. I've been trying to figure this out for weeks, but I can't seem to get any further. Hopefully there's someone on Freelancer who's wanting to show me this through a recorded video. For an experienced Blender user, this is most likely done in a couple of minutes.
I have a board, i need someone to build some codes to test the functionality of the boards. Its pretty simple, will share the schematic so one can refer the pinout. I just need some basic codes well written and editable so i can test the board well. Budget is fixed to 600 INR maximum, since it's fairly simple task.

I want to use the ESP32-S3 module with a RP2040 attached for a project. The RP2040 doesn't have any flash. Instead the ESP32 boots and once running downloads a binary from its own ROM into the RAM of the RP2040 by bit-banging IO47(SWD) and IO48(SWCLK) into the SWD port on the RP2040, then boots the RP2040. There is a discussion how to do this here. A post by Lurk101 half way down indicates he has got it working from a Pi So this code needs converting to run on an ESP32-S3. Just compile the standard "flash the led" C program into an RP2040 binary to test it. Obviously write it using the standard Espressif libraries for the ESP32 so the binary is saved in the standard file structure and
My project is for an ESP32 data logger and data history display. I need to log serial data from a sensor, which will be displayed in the form of a chart on a html data will then be stored in an SD card for future reference. I am looking for a freelancer with expertise in this project. I have a working sample. The esp32 is on APmode, uses a sd card to store the requested data from a sensor. The ESP32 host a webpage that users can log in and see the data stored, data is pulled from the SD card via http request on a file called data.txt. My problem is as follows: The chart only displays 20-40 data points stored. But if there is more, like weeks or month worth of data points it freezes or re-starts. I figured it has to do with the amount of time the http request takes ...

Hi, I need to program the LILYgo 7000G board to communicate via MQTT via LTE and wifi. It is also required to read the GPS position. Regarding the power part, it is necessary that the board goes into deep sleep consuming in general less than 50 ua/hour. To achieve that it should be possible to turn off the SIM7000G via software through the ESP32 and put the ESP32 into deep sleep. It would be necessary to see the rest of the electronic components and their power consumption.

I'm looking to build a charging device that uses the ESP32 micro-controller powered by a Li-ion (for example battery for a FireBeetle ESP32 battery port) or Li-Po battery which will be charged by a solar panel. At the same time (while charging) the ESP32 will be still working for the purposes it has been installed for (it will be working for 10 hours, between 09:00 and 19:00, so actually working only in the charging hours). Of course it should have protection when fully charged, to stop charging, etc etc. Please, only for hardware designers who have already made something like that. The other offers will be dismissed.

Connect an lcd display to a esp32, and a vs1053 board along with a lithium battery for a project. I also need appropiate code so that the esp32 can communicate with the display properly, and a system by which the vs1053 can send audio to an app. The app will analyze the audio and send back results to the esp32 and the display more details can be given. I can provide and send materials for the project. I already have a display, a battery, the esp32, the vs1053, and some connectors. Anything else I can buy, as long as it's relatively inexpensive. All I need is a functioning prototype and a possible cad design of the final device.
Hello, I need an Embedded software developer on the ESP32 to write an Ethernet Library, based on the official esp32-arduino Ethernet Library, to support for a custom RF module.

The aim of the project is to control the barrier mechanism at the entrance& exit gates of the sparking...the parking slot through a mobile app GUI like a flutter. The reason for that is to make a parking more smarter by pre-booking for the app, navigation helps them to find where they parked and payment. Controlling the barrier since uncertain behaviors can happen like leaving the car all day at the slot which is annoying others. Required for me to have the hardware: A microcontroller such as ESP32 / Arduino / servo motors / Leds / LCD and a space for a parking slot. Software: A GUI with features such as ( booking own slot in real-time, Navigation, and payment, and might more) I would like to hear from you very soon.

I have implemented a simple websocket echo server and a corresponding client that runs on separate esp32s3’s and communicate via wifi and it works. However the performance is very poor (~ 500ms for a roundtrip) so what I need is a optimization giving ~50ms roundtrip times. I have also implemented a python client and tested it against the esp32 server with good results (1000 roundtrips): Number of echos over 50 millies: 999 Number of echos over 75 millies: 40 Number of echos over 100 millies: 29 Number of echos over 150 millies: 13 Number of echos over 200 millies: 8 Number of echos over 250 millies: 8 Number of echos over 300 millies: 5
...the ESP32-S3 module with a USB port for a project. The ESP32 should boot from its flash and first detect if there is a USB pendrive plugged into it. If so it should copy two files - the executable file and the .HTML file from the pendrive to its flash. Then it should reboot, obviously now ignoring the pendrive and run a HTTPs secure webserver over WiFI in AP (access point) mode. Once a user logs in, the HTML file (about 250k) is served to the user, along with the application data from a 16384 byte RAM array on the ESP32 using the Websocket API. Changes made on the webpage by the user, usually using an Android tablet, also using the WebSocket API are stored in the RAM array, and also sent over the SPI bus to the rest of the system. At powerdown, indicated o...
