I made him a wizard hat... Halloween state of mind @EspressifSystem @Arduino

Repurposing a super cheap NMMiner to create an AI companion—it doesn’t speak, it only listens, I think... @EspressifSystem @Arduino

Using #OpenSCAD to add and subtract elements and create the enclosure for mounting the ESP32-S3 board vertically. #computervision @EspressifSystem @Arduino @waveshare00

Since the most common orientation of camera sensors is perpendicular to the Flat Flexible Cable, I am going to try mounting the ESP32-S3 board vertically. #computervision @EspressifSystem @Arduino @waveshare00

Using the Waveshare ESP32-S3 camera with display as line sensor to control the MAQUEEN Plus. Testing Micropython scripts remotely using WebREPL with Thonny and the ESP32-C6 Super Mini. #computervision @EspressifSystem @Arduino @waveshare00

After designing the mount for the Waveshare ESP32-S3 camera with display for the MAQUEEN Plus, I realized I needed to rotate it so the cables would exit from the bottom; it was like mirroring the parts. #computervision @EspressifSystem @Arduino @waveshare00

Creating a sensor for a Line Follower Robot using the Waveshare's ESP32-S3 2inch Capacitive Touch Display with camera.(25.0 FPS). #computervision @EspressifSystem @Arduino @waveshare00

Using the ROMI Robot Chassis with a 9V UPS and a custom I2C controller based on the #CH32V003. An #ESP32 running #MicroPython enables experimentation using WebREPL in #Thonny.

Cooling down the ESP32-C3 with a tiny antenna. With Arduino: WiFi.stTxPower(WIFI_POWER_8_5dBm); With Micropython: sta.config(txpower=8.5) @EspressifSystem @arduino #esp32

Holy guacamole! Asking Google AI: Generate the OpenSCAD code for: A rectangular block with internal dimensions of 43mm x 90mm x 22mm (height). Open at the top, with 2mm thick walls and bottom. Two external 8mm mounting tabs at the bottom of the short sides. #OPenSCAD

Testing my breakout board for the #CH32X035. Using the Arduino IDE to generate the hex file, and then using #WCHISPStudio to program it directly via its USB interface. Not bad for an industrial-grade 32-bit RISC-V microcontroller costing less than 50 cents.

The IMSAI 8048 can download or upload binary data. I will use an Arduino to convert the paper tape format into Intel HEX, enabling the use of a serial terminal like TeraTerm, PuTTY, etc. #IMSAI8048 #D8748H #D8749H #INTEL #Retrocomputing #MCS48 #Microcontroller

Benchy detected! Doing some tests to use E18-D80NK ir proximity sensors in simple model trains setups with the IMSAI 8048 replica. #IMSAI8048 #D8748H #D8749H #INTEL #Retrocomputing #MCS48 #Microcontroller

The relay module has arrived—time to test the relay routine from the IMSAI 8048 manual. #IMSAI8048 #D8748H #D8749H #INTEL #Retrocomputing #MCS48 #Microcontroller

Replacing my vintage microprocessor trainer's RAM with FM16W08 F-RAM is the best way to enjoy those nostalgic routines without having to retype them or deal with the hassle of a cassette recorder or serial terminal. #IMSAI8048 #D8748H #D8749H #Retrocomputing #vintagecomputers
