System Overview The Smart Knob is based on ESP WROOM 32E microprocessor module. The haptic feedback is realized by burying a BLDC motor in the main body of the knob. A magnetic sensor senses the direction of the knob and sends the angle to ESP32. ESP32...
Turn your Raspberry Pi (or nearly any Single-board or even regular computer) into a 133MS/s 32-bit Logic Analyzer, or a 3-channel 10-bit 'scope, etc.!-----------This project and its "father" were blogged at Hackaday! http://hackaday.com/2016/03/15/sdram-logic-analyzer-uses-an-avr-and-a-dirty-trick/(Thanks...
My post-holiday obsession continued until I am - finally - reading data from the Lepton using both PRUs in a Beaglebone Black. Given how - relatively - easy it is to use the PRUs I have to confess I pored over a lot of web postings before...
A small mini voice assistant robot to solve the troubles in individual use of intelligent speaker. As I want to have a voice assistant that can be customized started from the hardware and need to access to the voice assistant and control my own devices...
I started wiring up the Memory sub-system board and realized quickly that I needed the display board to show the state of the various registers. I first had to create a backplane to connect the boards into. The backplane carries all the signals...
BlueBoard#01 is... A 100mm by 100mm board that's for prototyping and one-off projects that use SMT and through-hole components. An earlier prototype Features 19 standard footprints2 x 1.27mm pitch footprints (10 pads, 28 pads)1 x 0.65mm and 0.635mm...
(Here's the complete description - sorry for some redundancy.) There are many single chip bipolar stepper motor controllers. These can supply one to two amps and work great for most NEMA 17 and smaller motors. But I wanted to control a long NEMA 23 motor...
Dyson V6 Setup and Running System Dyson handheld vacuum cleaners utilize high RPM brushless DC motors. Specifications indicate that some models can reach as high as 125000 RPM. I’ve disassembled DC56(V2), V6, and V10 models. Each has a brushless single-phase...
These are parts of AIME's operating system that I am beginning to shoe-horn into a Raspberry Pi or more probably a few Zero's networked together inside a smaller and less sophisticated quadruped. AIME was 3.2GHz dual-core intel powered and a lot more...
Basically, is a rectangular plane base with a CNC mechanism on it (ball-screw, two guides, cart and four linear bearings); the CNC simple mechanism is, actually, replacing an expensive actuator; on sides there are two triangular rods...
Top 3 struggles I have with robots and how this project solved them. 1) Cost too much. Mostly because of expensive servos and high end processors. - Designed a cheap driver/sensor board to read the absolute angle of the motor joint and run the...
