Circuit Design of Digital Thermometer The temperature sensor used in this project is LM35. The output of a temperature sensor is directly proportional to the temperature but in analogue form. Hence, the output of LM35 that means pin 2 is connected to...
What is the Anthro? The Anthropomorphic Robot is our answer to the lack of existing full-size humanoid robots available to the general public. What is preventing people from owning their own right now? There are three factors: Cost: Even if there were...
Hans Forsberg will host the Hack Chat on Wednesday, October 21, 2020 at noon Pacific Time. Time zones got you down? Here's a handy time converter! From our lofty perch atop the food chain it's easy to make the assumption that we humans are...
The project uses Edge Impulse FOMO (Faster Objects More Objects) custom ML algorithm to detect multiple objects and its coordinates using a compact micro-controller with on-board camera (Nicla Vision). The object detection ML model will use the...
Yet to be done or even researched by myself.Dataset collection: ⦁ Identify Domains and Use Cases: identify the use cases that the small system is intended to handle. For example, if the system is designed for home automation or if it's...
Having started my training in electronics with an 80C552 based development board, coupled with an eeprom emulator, the ability to modify and upload code was essentially as easy as it is with an Arduino these days.Rather than having to erase and burn...
This is my first Arduino project, so I'm using a SparkFun RedBoard (I'll worry about prettier form factors and portability once I have the basic operation down). /*The transcranial stimulator I made is a super cheap LM317 voltage regulator kit turned...
Chording keyboards are not new. Douglas Englebart (inventor of the mouse) also created a chording keyboard called the "Keyset". It only used 5 keys (for the 5 fingers), so only 31 codes were available. By extending the keyset to use 2 more keys, that...
Built with Open Hardware components: Arduino with Touch and Bluetooth shields. Pre-programmed with One-Touch keyboard that allows input by swipe gestures with one finger (or similar touch surface). Operating System independent. Works with both desktop...
This is a form of peaceful protest against the abusive handling of a boy who took an electronics project to school. The project was simply a digital clock and law enforcement decided to arrest and hand cuff the boy because it 'may' have looked like a...
Alright: so what I am attempting to do is to build a two axis CNC that spits pancake batter onto a hot metal plate.I'm diving into this project with minimal knowledge of this sort of stuff from before, I have pretty much no experience building similar...
My previous creation of CPLD board in the above picture is surely working for VHDL training, but it is too simplified and we need wiring of switches and LEDs for testing the results. Indeed the macro-cell in this CPLD is just 36 and just switch and LEDs...
Image processing is now a hot topic. It helps us to process images, analyse them, even to manipulate them and generate data from it. There's a branch of image processing that I just learned yesterday and that is OCR or Optical Character Recognition.OCR...
Getting the numbersThe images are captured with the notebook's camera with OpenCV and then processed to get more clear images for the numbers, then with Tesseract I get the numbers in text format.Choosing where to slideUsing PyBrain I create a neural...
Check out my latest project Hacking Wearables for Medical Device Development. Hack a $35 Arduino compatible nRF52 ARM Cortex activity tracker to build low power devices. Currently, used to prototype wearable medical devices at MATTER Lab. Complete...
