The arduino library supports A/D conversion at about 13 KHz, not fast enought for a useful audio-rate oscilloscope. Rewriting the acqusition loop to directly access the ADC reqisters speeds up conversion (including loop overhead) to about 688,000 samples/sec,...
If you look closely in the picture, there is a LOT more on this robot than is coded yet. I've included a PIR sensor, a microphone, and what's not seen is the little Radioshack IR reflection detector. The plan, once I learn how to use that last sensor,...

This project is very much a race against the clock. The idea for this project occurred to me after the first week of september, leaving three weeks before the end of the Square Inch Contest. Since it involves processor architecture, hardware and pcb...
At that moment in time, the "Hobby" computer was cut of the edge technology:- compatible with both of the major Z80 operating systems of the time: CP/M and ZX Spectrum- single (256 x 192) and double (512 x 192) screen resolution- hardware switchable...
1. Cel: Celem pracy jest wykonanie projektu urządzenia mechatronicznego lub kluczowego elementu urządzenia mechatronicznego, zbudowanego na bazie podzespołów LEGO oraz przeprowadzenie procesu projektowego zgodnego z rzeczywiście używanym...
Introduction I was suggested to create a project that allows people on bikes use leds to signalling their moves. This idea came to my attention as my dad is also a biker and I thought this could be useful. I recently tested wireless inductive coils for...

The plan here was to take an old Ekco radio and turn it into a modern Internet radio. There are lots of options here of course, but the one I chose is a project by Ed (edzelf). It uses an ESP32 micro-controller to provide all the heavy lifting...
The design as implemented from the original idea has the following features: Processing system ESP32-WROVER-I module with 4 MB Flash, 8MB PSRAM and external U.FL antenna connectionMicro SD card slot for data storageSeparate NXP MKL17Z32VFM4 ARM Cortex-M0+...
SolidCore CoreXY CAD Design In Fusion 360 All Metal Parts Our long term goal is to is to build a modular platform, not just a printer. Think of it as an ecosystem of parts that can be arranged in different configurations and adapted for unique applications....
The percentage of humans age ≥ 65 in the US is going up; and many seniors havemoderate to severe hearing loss.The original aim of this project was to design and build a system whereby audio from a television could be replicated in a pair of headphones...
Current version is seems working device, designed to be as simple as possible. It's build using common components, such as powerbank and 32x32 rgb led matrix. Some parts of enclosure are 3d-printed and front panel is CNC'ed acrylic glass.Actual recording...
Please check out the github repository, and the directions below. The main idea is to have the raspberry pi pico w: connect to the internet synchronize the real-time clock start taking magnetometer measurements in one thread serve up the webpage in the...
