Bluetooth Unleashed Design Challenge

131 posts
This is just a quick video to show what prizes were received for finishing more than 10 blogs in the Bluetooth Unleashed design challenge. Thank you very much element14 - this is a very useful collection of prizes.   For more info on the design challenge and my project see the links below....   Related Links: Bluetooth Unleashed Design Challenge Bluetooth Unleashed Design Challenge: The Challengers Bluetooth Unleashed Design Challenge: About This Challenge   Links to other blo ...
For all the parts to this project, click here! Smart Doorbell System   Introduction This short blog post discusses a wireless temperature probe! It re-uses hardware and software that was designed earlier, for a Smart Doorbell system. All the hardware and software is documented, click on the link above for deep-diving into it.   I was originally about to add some functionality to measure outdoor temperature, but then got bored when I realized it did not involve soldering - there is an ...
This blog post takes you through the building the Bluetooth maze, with multiple top plates as you see in the picture below. The Beaglebone Black Wireless is the brain of the project and is used to run the servo mechanism. Currently, I have two ways to run the servo mechanism as you see in the video below using a 2-axis thumb joystick and a BBC MicroBit which sends data to the Beaglebone via bluetooth. As of now I have two laser cut top plates with 3D printed parts, but I plan to add a couple mor ...
In my previous blog post - Bluetooth Maze - Moving servos using MicoBit , I had a huge problem were the 3D parts that I had printed using PLA filament were snapping because of the weight of the MDF. And based on my conversation with a bunch of folks at I local maker space who work on motor mechanisms/hydraulic for a living, suggested that I need to take the weight off  servos by having a metallic ball which I can place the MDF top plate on, so this meant I went to my local hardware store ak ...
Time for a short and quick update.   I took Project LOKI out for a little trip to the grocery store and wanted to show the results.     As you can see it was able to find 3 mac addresses while I was out.   Here is our Blue Book ready to carry out the clandestine adventures with Project LOKI.     Here you can see Project LOKI powered up and portable inside the Blue Book.   For further adventures I think I will have to look at better venting though sin ...
Hello everyone,   This is the final post. Which is good. Now that the project is complete I can think of enough enhancements to keep me busy for another 11 weeks.   Goal of this project was to see if I could use Bluetooth technology to implement a home security system. I originally wanted to use Bluetooth BLE for the project. When I saw all of the coding required and the steep learning curve I decided to go with legacy Bluetooth. Considering the small footprint that my HSS applicatio ...
For all the parts to this project, click here! Smart Doorbell System   Introduction The Smart Doorbell System is a Bluetooth Low Energy (BLE) project to build a better doorbell! However, it could also have other uses - to open and close gates, to act as an emergency attendant button or to control or monitor all sorts of things. It can also be connected up to a Pi or BeagleBone, for extending reach and capabilities even further. For example, the Pi could log and timestamp activity, or activa ...
As part of this blog post my idea was to post the final steps to build the Bluetooth maze, that is putting the 3D printing and laser cutting components together and have the servo mechanism moving, but I ran into a couple of problems. Basically I have found the the MDF top sheet that I have laser cut which would have the marble roll around is too heavy for the 3D printed servo mechanism, and it snaps the blue printed parts , and the one you see in the picture below are the 3rd version and are mu ...

  Hi, this is just a very quick update showing a longer video I made, using my laptop instead of the phone to handle the web interface of the Flask app. It showcases all the available effects and presents the parameter changes in realtime in a bit more dramatic fashion than my previous videos. Warning, tons of strobe lights ahead. ...
This roller coaster project had some ambitious goals because it is always fun to try and stretch to see if you can achieve them. Dealing with 7 MCUs and all the different development environments wasn't too difficult, but it was still lots of work. Designing the PCBs was fun and they worked well. However assembling 5 PCBs was a bit of a chore because they had hundreds of switches to mount. I definitely did not properly anticipate the time required to design 66 different 3D printed parts and prin ...
This blog wraps up work on the Type-N-Text (TNT) devices. It has come right down to the wire with only hours left in the challenge and I really wanted to get these devices working. I miscalculated the amount of effort the project would take pretty badly so everything would have had to go perfectly in the last 2 week to complete everything I wanted to achieve. But of course things weren't going to go perfectly and they definitely didn't. After completing the micro:bit-to-PSoC communication in the ...
I gave the mesh networking several tries but at the moment it is simply not workable.   Mesh network is not workable.  At least not now.   IMHO the STSW-BNRG-Mesh is not workable for the maker community. There exists this library and there are also examples included. But these examples work only with Keil uVision or IAR Embedded Workbench and both of them are proprietary and require a licence. Both of them have also a free version where the code size is limited to 32 kB. But the ...
Hello Everyone, This post covers the last of the sensors and the cameras. Included in this post are the Carbon Monoxide and Natural Gas sensors, the Range solenoid value, and both cameras. I decided to document the last of the hardware and software in this post and create a separate post for the summary.   The original camera kits I tried did not work out (Defender Security 720p DIY Surveillance Camera Module with WiFi. There was a quick start guide in the box. I never could connect to th ...
