The design uses an Arduino UNO Rev3, a stepper motor with a gear reducer, a rotary encoder, and an OLED screen, while a ground strap provides a current path that keeps welding current away from the electronics. ### Source excerpt MIG welding isn't very difficult -- at least not until you need to weld something at a weird angle or over a long seam. Those situations will make your welds look like they were done by an inebriated amateur. The best way to handle that is by setting yourself up to maintain stability through the [...] The post This custom motorized turntable makes welding easier appeared first on Arduino Blog. ## NuttX for Motor Control and Sensing: IMU Integration and Wireless Data Streaming DevFeed: [NuttX for Motor Control and Sensing: IMU Integration and Wireless Data Streaming]() Original publisher: [Read original article]() Author: John Lee Published: 2025-07-04T00:00:00Z Content type: tutorial Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32-C6](), [NuttX](), [Embedded Software Dev](), [Streaming](), [Hardware](), [Espressif]() Tags: [apache](), [blog](), [embedded](), [esp32](), [esp32-c6](), [espressif](), [hardware](), [how-to](), [i2c](), [imu](), [motor](), [nuttx](), [sensor](), [streaming](), [wi-fi](), [wireless]() ### AI overview This tutorial extends a NuttX motor-control system on the ESP32-C6 with MPU6050 IMU integration for vibration measurement and wireless sensor-data streaming over Wi-Fi to a host computer for visualization and analysis. ### Source excerpt This article extends the NuttX motor control system with inertial measurement unit (IMU) sensor integration for vibration measurement and wireless data streaming capabilities using the ESP32-C6 Wi-Fi connectivity. ## NuttX for Motor Control and Sensing: MCPWM and DC Motor Control DevFeed: [NuttX for Motor Control and Sensing: MCPWM and DC Motor Control]() Original publisher: [Read original article]() Author: John Lee Published: 2025-05-16T00:00:00Z Content type: tutorial Language: en Sources: [Blog on Developer Portal]() Topics: [NuttX](), [ESP32-C6](), [real-time](), [Application Development](), [Development](), [Hardware]() Tags: [acquisition](), [apache](), [application-development](), [blog](), [esp32](), [esp32-c6](), [hardware](), [how-to](), [implement](), [imu](), [measurement](), [motor](), [nuttx](), [real-time](), [sensors](), [speed]() ### AI overview This tutorial demonstrates motor control and speed sensing on an ESP32-C6 using the NuttX RTOS.

This involves going to flea markets to look for cheap vintage electronics like telephones, answering machines, radios or toys, and then desoldering and salvaging all the ICs and other interesting parts. Selected packages from my disorganized pile of chips follow. Most are POTS-related. Sony CXA1619BS A "one-chip-wonder", this is an FM/AM radio in a small package. It takes an RF signal (from the antenna) and an IF oscillator frequency as inputs and outputs demodulated monaural audio. Sanyo LA2805 This chip does general answering machine related tasks. It has a tape preamp for recording and playback; voice detector logic; beep detection using zero-crossing comparation; power amplifier; line amplifier; and pins for interfacing with a microcontroller. Unicorn Microelectronics UM91215C The UM91215C is a tone/pulse dialer. A telephone keyboard matrix is connected to the input pins, and the chip outputs DTMF-encoded audio or pulsed digits, depending on the selected dialing mode. An external oscillator needs to be connected as well. It can do a one-key redial of the last dialed number, and it can also flash the phone line. Holtek HT9170 A DTMF receiver, reversing the operation of UM91215C above. The chip, employing filters and zero-crossing detectors, is fed an external oscillator frequency and telephone line audio, and it outputs a four-bit code corresponding to the DTMF digit present in the signal. The use of external components is minimal, but a crystal oscillator is needed in this case as well. SGS-Thomson TDA1154 A speed regulator for DC motors, this chip can keep a motor running at a very stable speed under varying load conditions. In an answering machine, it is needed to keep distortions in tape audio in the minimum. Toshiba TC8835AN This chip can store and play back a total of 16 audio recordings of 512 kilobits in size. It also contains a lot of command logic, explained in a 40-page datasheet.
