A detailed Walksnail Avatar X brick-recovery log using direct W25Q01JV QSPI access, Raspberry Pi Pico pico-serprog, flashrom, SPL/U-Boot repair and the official 39.44.18 updater.
AMD BC-250 ā building a DIY Steam Machine
Something a little different from RC this time š An AMD BC-250 mining board is getting a second life. The plan is to turn it into a Linux computer, and eventually my own Steam Machine. First up: sorting out the cooling. The original heatsink needs a few changes for fans blowing down onto it. I […]
Testing a General-Purpose Wireless Link with Live Image Data
Some projects are built for one specific job.This one is not. The radio link Iām working on was not designed specifically for image transmission. It is a more general wireless transport built on my own firmware running on a Raspberry Pi Pico 2 with an SX1280 transceiver. The modulation is FLRC, and the link uses […]
Small DIY LCD display
QCZEK LRS for ASR6601-based modules with 27dBm RF output.
A fresh version of Qczek LRS firmware is now available, optimized for ASR6601-based modules with 27dBm RF output.Check out the full update details and flashing instructions.
Tasmota-based smart plug as a power regulator
This is a method to convert a Tasmota-based smart plug into a power regulator. I used the AVT 1860 kit as the output component, replacing the potentiometer with an optocoupler. The optocoupler is driven by the unused ESP GPIO 0. You can find the schematic and a few photos below. Iām not providing a detailed […]
pix2pix for FPV ?
Justy playing with pix2pix model to convert small semantic maps into FPV views.. Use only 15 colors for sending a minimal data stream … but the results are not as expected š
Something completely different – DIY blood smear
My first try, using 3d printed https://openflexure.org/ microscope š
Building OpenIPC FVP gears
It’s amazing that someone spend their time to run wfb-ng directly on CCTV camera board running hacked linux OS. The RX part is also amazing because it utilize $20 Nvr board š If you want find out more you need to follow the guide https://github.com/OpenIPC/wiki/blob/master/en/fpv.md The thing i done it’s only design of 3d printed […]
LoRa chip running whole device
In an era when the average application occupies many megabytes and requires dozens of libraries to run, it is still possible to fit the entire functionality of a device in 40kB of flash memory. Therefore, a single small ASR 6601 chip, in addition to LoRa radio communication, supports a display, buttons, joystick, UI, and more. […]
