Hello,   Is anyone working on the use of the Raspberry Pi Camera module as a heart rate sensor? I am new to using Raspberry Pi. I want to build a non-contact real-time heart rate monitoring system using Raspberry Pi 3 Model B and Pi NoIR camera. I found two related projects which are: https://github.com/prouast/heartbeat https://github.com/thearn/webcam-pulse-detector   Is it possible to build this system using Raspberry Pi? Also, Is it possible to calculate FFTs and FFTs on the ...

Raspberry Pi Kiiboard

Posted by rctho Jan 31, 2018
Another as seen on the internet project. I scored a busted Happy Hacker keyboard at work so naturally, i took it apart. most of the broken pieces i would have had to melt off to make the Pi board fit into it anyway.     The challenge; how do i get this Raspberry pi into a small keyboard that already had a pcb in it.     First i had to remove everything from the board. I started off delicate cause i didn't want to damage it, but these lil' guys are tough! i had to be p ...
The Remote Home Monitoring with Hologram Nova will encourage you to upgrade your home to a smarter and more secure one, offering safety measures, protection, monitoring and key indicators for later improvement using the Nova Cellular USB Modem and the Raspberry Pi. This project is not about just turning ON/OFF a light from a smart phone. It is focused on integrating a network of sensors, nicely presenting the data in a dashboard, monitoring and controlling all the features with a simple and frie ...

Hi guys, i'm searching for people that would like to join me adding this nice emulator on the PI. NeoGeo CD SDL does have cd-rom only support and it's a great choice for people like me that would like to have a "new" neo geo cd, because the original hardware is expensive, unreliable and had low loading times.   This emulator was maded for DOS, then went for Windows, then it was ported to linux, beos, Xbox, Dreamcast end even Ps2. There's a new console coming up, called SEEDI, that'll be ...

I tried to use the Element14 Pi Desktop.  My mSATA disk works when I use a USB adapter on Windows.  When connected in the desktop, I try sudo  ppp-hdclone which doesn't see any drives. When I reboot with bootable microSD card reinserted, I see four raspberries but nothing happens after that.  It appears all USB connected devices no longer work.   Can my Raspberry Pi 3 be unbricked from this situation or is this Pi gone forever? ...

What's a PiJack?

Posted by rctho Nov 21, 2017
I needed to extend the wifi range of my router with a minimal footprint in my apt. I didn't want more peripherals plugged in all over my apt. I used a RPi0w for the wifi repeater and jammed it into a two gang receptacle box. Two usb ports (one is for console connection) and kill switch, or reset button in case the computer hangs. The console connection will also power the Pi in case the power goes out.   First i had to attach the antenna. I found tutorials online that looked easy enough ...
Hi everyone!   We're a group of students from Royal Holloway, University of London participating in AstonHack 2017 and we think we've come up with something neat. https://astonhack.co.uk/We've made a command line interface for Monzo Bank! Sadly, as the API is currently read-only, so only data viewing purposes for now. The monzo-cli tool has many useful features, these include: Viewing current account balance. Example: ./monzo balance View pending transactions - these are transactions ...
A pedometer is an electronic device that estimates the distance traveled by a person by recording the number of steps walked. Pedometers use an accelerometer to count the number of steps. A Raspberry Pi SenseHAT records acceleration along X, Y, and Z axes. You can use Simulink to record this data over a duration of time using the MAT-file logging feature. You can then use MATLAB to analyze the imported MAT-files to count the number of steps. To use the MAT-file logging feature with the Simulink ...
Halloween is one of my favorite holidays here in the US, and so much so that I spent a few years of my life thinking up and building smart Halloween props and animatronics for the haunted attraction industry. I won’t go too deep into the details of the business, but a few friends and myself founded a company a few years back with the “help” of some investors. It was my first tech startup, and like many tech companies, we had the hardware and software to revolutionize a decades ...
