DIY SonarFirst lets start with the expected signal level.Based on the 400RT160 datasheet (http://www.robot-electronics.co.uk/files/t400s16.pdf) and the Pro-Wave Electronics Corporations application note (http://www.prowave.com.tw/pdf/an0508309.pdf) the...
The Forward ChannelI have simulated many options but I have not really done much better than the current setup. The backward channel without any additional filtering is suppressed nearly 20 dB. Really I have to wait until I physically test the modem...
In this post, I will go over details to drive the robot manually using keyboard and command line. I won't go over the details of setting up raspberry pi Raspbian OS as there are many good tutorials and it's not the main point of this project. Once you...
Prototype delays due to electronic components shortagesAs already stated a few times, we are still victims of the electronics industry supply-chain difficulties. Back in July, we informed you that “98% of more than 2000 components are now secured...
Summary: I first try to get a UART up to provide some I/O for the shell. Half seems to be working. Deets: For my first step, I am going to simply get a serial port up with the System Workbench HAL drivers, and attempt to wire that into the eLua. ...
All documentation for the expansion board is available on the Supercon Badge project page. Of course you can do a ton more than this hardware, but blinkies are always the first step! A Demo: The Hardware: The hardware couldn't be simpler. I added a 595...
Today we’re pleased to share with you a series of Python examples for OpenCV development. This code works with either the StereoPi or the Raspberry Pi Development Board, as both support using two cameras simultaneously. Our ready-to-use code (and also...
The following log is going to be a bit of a brain dump on the current state of the firmware/software development. This snapshot is captured in the R0.3 ROM uploaded to the files section today (also tagged in the Git repo). First a quick overview of how...
One last thing that was still missing was the symbol table. Apparently the output of the softmax layer maps directly to the symbol table, and since this output is 128 in length, I was searching for a table of this same length.The prime suspect was of...
The project is wholly composed by off the shelf components: ESP-01ArduinoDS3231 RTCNeoPixels5V to 3V3 regulator The ESP-01 creates a hotspot and serves a page with a form and a button The Make it Glow button maskes the ESP01 send the string typed ...
The Binary Encoder The first Working Digital Computer module described in the book was the Binary Encoder. Here's what it looked like: It's job was to accept decimal input from the operator and convert it into binary codes the computer could use. ...
Overview This guide provides instructions, code and components on how to build a internet enabled home automation system that allows scheduled control of multiple sonoff wifi enabled switches as well as routed control messages over the internet using...
This contest has ended and the winners have been announced! Thank you all for participating! TL;DR Phase 1 ends June 1st: We'll ship 50 people free kits and cloud credits! Submit an IoT project idea that uses one of Cypress’ PSoC® 6 Wi-Fi/Bluetooth...

A Chaser Circuit consists of a clocked IC or other electronic unit like an Arduino that drives an array of LEDs in such a way that individual LEDs (or small groups of LEDs) turn on and off in a predetermined and repeating sequence, thus producing a...
