This week I moved onto the challenge of determining which solution would make the ideal “maître d'” for the system, as in, which type of device would provide both the best central control function and the best user satisfaction.   I had three BLE-enabled candidates to consider, namely an Android tablet (in my case I'm testing on an Amazon Fire 7" tablet), a Cypress CY5677 USB dongle and a PSoC 6 BLE Pioneer board with E-Ink Display Shield, which I had initially suggested w ...
As part of project – Bluetooth Maze, I am using BBC Micro Bit as a supporting actor to the Beaglebone wireless which is my Hero board. In this blog post my intention is to test out a couple of features of the BBC Micro bit which I intend to use in my project. Basically, the BBC Micro bit is going to act as the controller, to control the Maze which I going to be sitting on/controlled by the Beaglebone Wireless and servo motors. The Micro bit will be sending magnetometer and accelerometer va ...
I have been immersed in trying to learn how some of the subsystems I chose for this project actually work. Current and Voltage Measurement The belt-driven DC generator  on the Stirling engine flywheel outputs voltage and current that will be monitored by a Texas Instruments INA219 chip. This chip uses an I2C interface and has half a dozen registers to deal with. The INA219 chip is mounted on a small PCB with a shunt resistor: Temperature Measurement This project uses type K thermocou ...
Introduction Hi! This will be my second update on the project BEEP. In the last blog I covered the idea and plan behind the whole project, and for this one I'll cover the first one of the modules, the ultrasonic module. As the name suggests this module uses an ultrasonic distance sensor (HC-SR04). When I think of a sensor this is the one that first comes to mind. It is really simple to use and yet works really good with sensors based on that technology all around the place. My idea is to create ...

Description of the Problem Plants need water to develop well and stay healthy.   Healthy and not so healthy plant:   This sounds very simple and everyone understands it. Neverless plants sometimes have to suffer dryness simply because the owner has forgotten them. Or they get to much water so that they drown.   In a private household watering the plants is a managable task but also creates some trouble. When you go to larger buildings like office spaces or public buildings, pla ...
Hello guys, Before I start I need to thank our community members. That was a lot of thoughts and tips tried a few and realized the issue was the model itself, that was a huge data set to be processed and matched so we decided to do something else. So before starting with the that, there was sweet suprise, thanks todanzima. The kits have arrived.... It was the Rpi 7" Display, Camera Module and Arduino. Although I'm having some issues with Camera Module v2.1, working on it, for now we ar ...

Good day!   Today I want to devote my article to programming, namely the implementation of the basic functions of a bike computer, the formulas for which we defined in the two previous articles. However, how can I program something if this is something I do not have? The answer is simple – to perform castling, in my case the king’s role is played by the FRDM-KW41Z still expected by me, and the rook’s one – by the FRDM-K64F!   My choice, I think, is obvious, ...
This week I decided to move onto the flashy part of my project (excuse the pun), which was to start playing with my NeoPixels or addressable RGB LED’s that use a WS2812 driver.     The purpose of the neopixels for my project is to provide a visual indication from afar of any customer requests and/or status change notifications.   So, as I’ve never used neopixels before, I thought to document some of my findings and my progress as I work through the process of getti ...

The Stirling Blue project will be measuring several Stirling engine parameters including inputs and outputs so I can calculate efficiency. The input to the engine is fuel - alcohol in this case, and I will need to know how much is consumed. I could do a before and after weight measurement, but I want the PSoC6 to be able to monitor all parameters in real time. The gas tank is actually a 10 ml glass jar. The fuel is drawn out using a wick that also acts as the burner. This blog explores using cap ...
Hi guys,   There's been a lot of confusions, lots of algorithms, lot of choices for the face analysis part. Spent a lot of time over it, learnt a couple of new things, so what else it was time to test things out.   I started with the traditional way, template based matching had to take around 35 pics and my beard for better accuracy, after a bit of enhancements and the discovery was, I'm really bad with Expressions it wasn't working the way I want it to. So the next option was to ...
I’ve been having a bit of good fortune this week so thought to crack on while the going is good.   It turned out that the substitute product I ordered because of a stock out with my original choice was way better than I ever imagined. It locks on tightly to the micro:bit and makes connecting external sensors and peripherals during developing and testing phase so much easier.   My Gallery Title   Then, to get to use the Arduino IDE for microbits you need to go to Boa ...
Good day!   This week I want to continue my mathematical calculations. Last time I made the assumption that the force needed to pedal the exercise bike is constant and equivalent to that of a real bike riding straight on High Gear. This statement is valid only if you ride an exercise bike always with the same tension.   Today I plan to do the following: determine the actual force (or rather the torque) created by the exercise bike, depending on the position of the tension knob; cal ...

Redesigning Modules

Posted by lexbryan May 17, 2018
Last year, I built a prototype for my farm. I was invited to exhibit it during the ASEAN Slingshot Conference: Maker Edition. Because of lack of materials, I improvised on the design and materials and I encountered a lot of problems during the exhibit. Since the board hasn't arrived yet, I went on to sketch and redesign my modules.     ...
This is my first blog post regarding actual work on the project, as well as some basic info on my Hero board - the RedBear Blend v1.

The first one is already here Unboxing the RedBear Blend My hardware My software Up next   Unboxing the RedBear Blend My Hero is an Arduino Leonardo-compatible board with a castellated N ...
Hello everyone, I am still waiting for my Bluetooth devices. However, I decided that I should test the Bluetooth adapter on the BeagleBone Black Wireless in case the adapter was defective. I did not want to wait too long if I had to replace the BeagleBone Black. I used a HC-06 Bluetooth device, from a previous robotics project, to communicate with the BeagleBone Black Bluetooth adapter. The HC-06 was attached to an Arduino Uno.   I ran into one problem. I had to fix an SAP driver error th ...

Introduction Hi guys! This is my second design challenge and I am incredibly happy to be chosen as one of the challengers. The idea for this project comes from two separate ideas that merged into one. First of all let's explain the name BEEP. The name BEEP stands for Bluetooth Empowered Education Pi. As the name itself suggest the heart of this project  will be a Raspberry Pi 3. First of all the thing that fueled the idea behind this project, I was one night sitting on the bus returning hom ...
The Stirling Blue project will be using 4 hero modules plus a couple of PSoC modules which total up to at least 8 ARM chips, and at least 3 different integrated development environments (IDEs) to handle all the software. It will also have 5 custom PCBs, which need to be designed early, to ensure delivery within the project schedule. This blog covers the PCBs that will be used with the BBC micro:bit. I want to use the micro:bit as a BLE display for Stirling engine data, but its LEDs are not reall ...

Project Plan

Posted by lexbryan May 12, 2018
Ardufarm is a modular aquaponics farm. It is composed of plug-and-play components such as filters, computer module, grow buckets, and etc. One farm may consists of one or more computer module. For a large farm, Wifi connectivity becomes a problem. This project will focus on the mesh network using pycom boards. Once no wifi is detected, the board will send the data through the nearest bluetooth device.   ...
Good day!   This week I want to talk about simple measurements, namely about measuring the speed and distance traveled on an exercise bike, but let me first present to you my exercise bike.   This is the most common exercise bike manufactured by Atemi, which I used for many years as a clothes hanger, and only the last three years I have used it for its intended purpose – for sports, and as a result the device suffered minor damage: saddle has sagged; steering has broken (it ...
Hello everyone,   My BeagleBone Black Wireless is up and running. I was able to configure the Wi-Fi and access the BeagleBone Black via the Putty terminal emulator. Although, I think any other terminal emulators would have worked as well. I configured a web server and was able to access the BeagleBone Black’s onboard LEDs from a webpage. I decided to hold off configuring the onboard Bluetooth module until I get some Bluetooth LE components to communicate with.   I did run into ...

Greetings  Thanks Element14 for sponsoring my design challenge. My PSoC 6 BLE “hero” Pioneer kit arrived today and I am now thoroughly looking forward to the next 11 weeks or so as I take my idea and develop it into what I hope will be a winning prototype application.   Unlike most bars and restaurants, I got plenty of notification of my hero’s journey from Element14 HQ to my front door. It is this transparency that I am intending to replicate using Bluetooth Low En ...
My project for the Bluetooth challenge is a fun game, I have called it a “Bluetooth Maze” , but it is basically an over engineered Labyrinth , to be controlled by a servo/stepper motors mechanism and use one of the Bluetooth Hero boards to drive the mechanism.  Basically the idea here is to bring the Labyrinth board game to the 21st century. Now if you’re a millennial and wondering what is a Labyrinth is – it is a game of physical skill consisting of a box with a ma ...
This is just a quick update to introduce the hero board I will be using for the Stirling Blue project. The PSoC6 is a dual core system on a chip with an ARM Cortex M4 (150 MHz) and and ARM Cortex M0 (100 MHz) in the same chip with 1MB of Flash, 288 KB of SRAM, 78 GPIO 7 programmable blocks, 56 digital blocks and Bluetooth Low Energy. I've never seen a 100MHz Cortex M0 with all these resources and of course the Cortex M4 takes the performance to a whole new level. PSoC Creator makes it really si ...
I have been fascinated with Stirling engines ever since studying them in University. Although we got to measure performance of internal combustion engines in great detail, we only analyzed external combustion (Stirling cycle) engines theoretically. The PSoC6 Pioneer Kit makes it feasible to put together a capable instrumentation system to examine Stirling engine operation and performance. Working with a physical Stirling engine will be so much more interesting than just analyzing Carnot cycles. ...
Waiting for my board and components to arrive, I would like to present an intro to my project – the Universal LED Animator. It is a combination of a hardware kit (a base station and some beefed-up LED strips) and a web application that together allow their user to endlessly customize animation patterns on their lighting setup. My Hero board is the RedBear, and I'm also using a BeagleBone Wireless. I already have addressable LEDs in satisfactory quantities so I can start working on the proj ...
Introduction This first blog post in the Smart Doorbell System series discusses why one would want a better doorbell, and introduces what will be at the heart of it - the CC2640R2 LaunchPad board, and briefly explores its microcontroller.   This blog post also discusses how an enclosure could be created using Autodesk Fusion from the circuit board CAD files. A nice enclosure is important for consumer applications.   Motivation Most existing wireless doorbells (lets call them doorbell ...
Good day!   During last 3 years I have been spending approximately 2 hours a day doing sports: I have been riding my exercise bike. Over these years I created my own sport-program for exercise bike. This program seems to be quite complicate since you need to do a lot of calculations when you ride. But soon it will not be a problem because I have a good idea which I intend to implement in this project! I want to create my own special computer for exercise bike which will execute my control ...
Hi Guys,   This is going to be an usual intro, an exact copy of my application with some add-on. Before getting started with that, what is AAPSAD???? AAPSAD is an acronym for Adaptive Ambiance for People with Stress and Depression.  Where and how did this came into my mind? Most of us would have been with or passed through people with depression or mental illness, which goes unnoticed until something serious happens. A few of us would have lost our loved ones, inspirations to depres ...
Hello everyone, I just received my BeagleBone black. So, I decided is was time I get started on the project. I decided to review my application before posting it here (See below) and noticed several grammar errors in the document. So, I fixed the errors. Hopefully I corrected all of them.   In my next step I will boot-up the BeagleBone Black. Then I will configure the Wi-Fi, configure a web server, and configure the Bluetooth module on the BeagleBone Black. As soon as the tasks are complet ...
We have all heard it before.  Heck I have even said it.  Just because you don't get selected as a Sponsored competitor in a Design Challenge it doesn't mean you can't compete.  If you have an idea and you want to see it through to the end, go for it!   Well with the release of the latest Raspberry Pi 3b+ and this latest Bluetooth Unleashed Design Challenge I thought what a great way to take the two and combine them.   Sadly I held off on applying for the Roadtest of th ...
