≪ Erste Tests ≫

Das ist jetzt zwar nicht der ESP32-C3 Mini, der schlussendlich auf den Dachboden soll, tatsächlich kommt dort eine Version mit einem externen Antennenanschluss hin, aber einen ersten Test lasse ich mir dann doch nicht nehmen. 😀

Working toward running #microReticulum natively on the LilyGO T-Beam SUPREME (ESP32-S3 + SX1262).

Hardware exercises complete (GPS, OLED, SD) and basic LoRa ping-pong via RadioLib.

Next: implement a proper Reticulum LoRa interface layer for SX1262 on ESP32-S3 — binding microReticulum’s interface abstraction to SPI/DIO/TCXO for full RNS operation.

Interested in collaborating or testing? #Reticulum #LoRa #ESP32 #TBeam #Meshtastic

:github: A compact, Browser-based ESP32 Oscilloscope.

An oscilloscope is usually the most sensitive, and arguably most versatile, tool on a hacker’s workbench, often taking billions of samples per second to produce an accurate and informative representation of a signal. This vast processing power, however, often goes well beyond the needs of the signals in question, at which point it makes sense to use a less powerful and expensive device, such as [MatAtBread]’s ESP32 oscilloscope.

👾This isn’t the first ESP32-based oscilloscope I’ve seen, though it is the fastest.👾[ImageSource: MatAtBread]

⁉️The oscilloscope doesn’t have a display; instead, it hosts a webpage that displays the signal trace and provides the interface. Since the software uses direct memory access to continually read a signal from the ADC, it’s easy to adjust the sampling rate up to the hardware’s limit of 83,333 Hz.⁉️

In addition to sampling-rate adjustment options, the browser interface includes a crosshair pointer for easy voltage reading, an adjustable trigger level, attenuation controls, and the ability to set the test signal frequency.

👾The oscilloscope’s hardware is simply a Seeed Studio Xiao development board mounted inside a 3D-printed case with an AA battery holder and three pin breakouts for ground, signal input, and the test signal output.👾

I have two small #ESP32 dev boards with OLED. They seem to be Heltec WIFI LoRA 32 V1.x boards.
I can’t find them on the manufacturer’s websitite anymore.
heltec.org/ (v2, v3, v4 look similar, but are different.)

Only board info I can find
tha.de/~hhoegl/iot_workshop/do

Could I maybe use them for #Meshtastic or #Meshcore?
So far, no luck getting any firmware to work. Flashing works correctly though. Just doesn’t seem to match the hardware.

Or is it not worth trying with these relics?

Small white PCB. A USB Micro-B connector to the left, buttons labelled PRG and RST. A coil antenna and 2 LEDs. Then a blue OLED display. and an antenna connector to the right.The underside of the PCB with a battery (JST) socket, ESP32 microcontroller, CR2102 LoRa radio, and a chip that I’m guessing to be a voltage regulator. There’s also a printed PCB WiFi antenna and four screws that keep the OLED display on the opposite side in place.Top side of the board again, this time in high-resolution. Only difference to the first image is, that the display is off, because there’s no power connected.

Which case actually makes sense for a LilyGO T-Beam SUPREME in real field use?

I compared designs, materials, print costs, and durability (PLA vs nylon vs resin), plus SD-card access. Includes a side-by-side video (7' 49") comparison.

Two cases: 1) LilyGO designed and 2) Alley Cat designed.  Both for the LilyGO T-Beam SUPREME.  Pianistic hands included in picture to give relative size.

Anyone know of a gemini implementation for on a esp32?

Please don't respond if you think this has anything to do with AI. <3

🖨️ ePaper displays are ultra-low power and sunlight-readable, but come with slow refresh rates, limited colors and relatively high prices. Perfect for digital signage, electronic labels and eReaders.
🎥 In my spare time I created a video tutorial to explore using the same 4.2" monochrome ePaper (400×300, SSD1680, SPI) display with two different controllers: the @seeedstudio EE04 with XIAO ESP32-S3 and the ePaper Breakout Board with XIAO ESP32-C3.
