You might remember my musings with the XOR gate with interlocked NPN transistors discussed at Bipolar XOR gate with only 2 transistors But thinking about how XOR is done with pass transistors in CMOS and the structure often creates a MUX, I wondered...
Edit: See also More 2369, with more caps !With a sporadic and limited access to the workshop (at last !) I can finally try new ideas ! I have meanwhile received 9K PMBT2369 in SMD but I decided to use the old stock of 50pc 2N2369A in metal can, that...
Flash the Arduino with the following sketch. This is also included as a file attached to the project. int last_level = 0; bool last_state = false; bool stable = false; int count = 0; const int cutoffs[198] = {/* 1*/ 833, 831, /* 2*/ 825, 823, /* 3*/...
Note: this log is obsoleted by BitsliceAfter the last log Adder with Falstad, I also converted the ROP2 bitslice to the interactive simulator : There is still the challenge to disable the output of the CLA so it can be combined by ORs with the rest...
The Technogym manual indicates that the RF HR receiver outputs a 5V and 30 ms pulse for each heart beat. A ESP32 with abilities will be the perfect µc. It's a easy job for it to read the incoming HR value and to output a pulse. Since the ESP32 works...
You can find the schematic ready to edit and go on EasyEDA here. Source code for the Arduino sketch is attached and below. Note that it uses the TimerOne library to provide higher-resolution Timer1 frequency control for the Pulse Width Modulation to...
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...
HARDWAREESP-32: The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESp32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes fully-equipped...
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 ...
What if I told you it was possible to SAFELY use ANY SmartPhone as a robot brain? On any smartphone with a browser, load a freely hosted github.com webpage with Javascript that blinks areas on the screen to send motor commands to an e.g. Arduino....
In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...
The ideaI’m David, and my goal with this repository/article is to demystify Sockets by try to explain them in the simplest possible way.In these examples, I’m going to use NodeJS and Particle (any version will do) to show how hardware can talk with NodeJS,...
