My neurologist advised that I should try EEG Neurofeedback. Unfortunately public health insurance doesn't cover it.

Well, I'm just going to DIY it. I just ordered an open source Neurofeedback device with some electrodes.

Everything costed me just under 200 €, which is roughly the cost of a single session. I'm by no means a trained professional, but I think I can make up for it with unlimited free sessions.

EEG-SMT - Open Source Hardware Board

Low cost open source EEG device completely assembled USB interface

Olimex

Just got one of my more involved Home Assistant integrations online. We added a pressure transducer to monitor the water pressure for our pressure tank (where the well pump comes in). We have an Olimex PoE ESP32 there already and I decided to custom design and fabricate a PCB (first time ever) as a hat for an ADS1115 ADC and connectors.

It works! So we can now monitor our water pressure in excruciating real time precision. Just because.

Ahora que se puede vincular teclados bluetooth al #ESPectrum ha llegado la hora de independizar mi #Olimex de otro cable, el de alimentación, con una batería…

@olimex Does this ili9486 Touchscreen also work on older RapberryPi version than v5 ?

EDIT: Hm Will not work, because the case and holes doesn't fit on Pi4 ...

Olimex ESP32-P4-PC is an open source IoT board with a 400 MHz dual-core RISC-V chip and plenty of I/O for $29

Open hardware maker Olimex has introduced a new development board powered by an ESP32-P4 processor featuring a dual-core 400 MHz RISC-V processor, and a low-power 40 MHz RISC-V microcontroller core.

With just 768 KB of internal memory, 32MB of PSRAM, and 16MB of SPI flash storage, the Olimex ESP32-P4-PC is clearly not meant for use as a general purpose computer. But it’s a fairly versatile […]

Olimex ESP32-P4-PC board offers HDMI video output, Ethernet, four USB 2.0 ports, and more

Based on an Espressif Systems ESP32-P4NRW32 SoC with a 400 MHz dual-core RISC-V CPU, 768 KB RAM, and 32MB PSRAM, Olimex ESP32-P4-PC is one of the most feature-rich ESP32-P4 boards on the market so far. The open-source hardware board features 16 MB SPI flash, HDMI and MIPI DSI display interfaces, a MIPI CSI camera interface, a 3.5mm audio jack, Gigabit Ethernet, and four USB 2.0 ports, as well as a UEXT connector and a 20-pin GPIO header for expansion. It takes power from a USB Type-C port, a LiPo battery, or PoE through an add-on board. Olimex ESP32-P4-PC specifications: SoC – Espressif Systems ESP32-P4NRW32 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz Memory 768 KB HP L2MEM (for dual-core CPU), 32 KB LP SRAM, 8 KB TCM (for LP MCU

ESP32-C6-Devkit-Lipo – A small, open-source hardware ESP32-C6 board with battery support, UEXT connector

Olimex ESP32-C6-DevKit-Lipo board is a small open-source hardware board based on the ESP32-C6 WiFi 6, Bluetooth 5.0 LE, and Zigbee/Thread SoC with support for LiPo batteries and UEXT expansion modules. It's the second announcement from the company this week, and comes after they introduced the MOD-ESP32-C5 to add wireless connectivity to boards equipped with a UEXT connector. The ESP32-C6-DevKit-Lipo adds to the list of small ESP32-C6 USB-C boards, such as the 01Space ESP32-C6 board and Seeed Studio XIAO ESP32C6, among many others. It's actually larger than most similar boards, but differentiates itself with its open-hardware design, dual USB-C design, breadboard compatibility, LiPo battery circuitry, and a UEXT connector. ESP32-C6-Devkit-Lipo specifications: Wireless module – ESP32-C6-WROOM-1-N4 module Espressif Systems ESP32-C6 SoC CPU - Single-core 32-bit RISC-V processor @ 160 MHz Memory - 512KB SRAM, 16KB low-power SRAM Wireless 2.4 GHz WiFi 6 1T1R with Target Wake Time (TWT) support Bluetooth LE 5.0

From the #DECtalk Mini github repository I commpiled with the #Pico-SDK today the RPi #RP2040 Pico version and changed it
from USB serial 115.200 Baud
to GPIO0/1-TTL-Serial 9600Baud.
Sounds fine on the left 3.5mm Audio channel
(GPIO28/Pin 24) of a
#Olimex RP2040-Pico-PC Board :)
