Unboxing the Bluz Dev Kit – Kickstarter

logo_nobg
In April of 2015 I found a Kickstarter called Bluz which offered a cloud-connected Bluetooth LE development kit that could be run off a coin cell battery for months or even years on end. The Bluz is very similar to a product called the Particle Photon released earlier last year and the Photon has quickly become one of my favorite development platforms for developing Maker projects. I figured that a Bluetooth LE dev kit would be a great addition to my maker tools.

After a bit of wait, it arrived on my doorstep and I figured that I would record an unboxing video and a simple test with the Bluz.
Since I pledged $49, I received what they call the Wearables Kit which included one Bluz dev kit, a Coin Cell Battery Shield and an Accelerometer shield.

The accelerometer shield that I received was not a custom Bluz created one, but actually a Sparkfun branded shield that I had already purchased on my own (an extra never hurt).

The coin cell battery shield is unique to the Bluz and allows it to be powered off a single coin cell battery. Included in this shield is an on/off switch that is surprisingly missing from the number of other battery shields that I’ve bought and tested.

The Bluz itself looks very similar to the Particle Photon and actually has the same footprint so that it can take advantage of the same shields as the Photon. It even piggybacks off the Particle’s online development tools and the same deployment pattern (aside from the need to be hooked to a gateway that I’ll talk more about later). One big difference in the immediate presentation of the Bluz is that it does not have a micro USB port for powering it. This is partly due to the fact that it can supposedly last longer periods of time on very little battery and its primary purpose is to not be continually connected to an outlet. The’ recommended method of powering it is to use the coin cell shield, or the VIN, or 3.3V pin
For my unboxing, I didn’t have a method of powering it through the Vin or 3.3V pin directly or a coin cell battery lying around, so I decided to use a Particle Shield Shield in order to breakout a DC Power connection (which ends up powering it through the Vin pin anyways).
The major thing to know about the Bluz is that it needs to be connected to a gateway or the Bluz iOS or Android apps in order to communicate to the cloud. While there are plans to open source the iOS and Android connection code, they haven’t been released yet and this is a pretty big limitation for anyone like myself that wants to use a direct communication line between Bluetooth devices and the Bluz. However, Bluz sells a gateway shield that can be attached to a Particle that allows up to 8 Bluz to connect to it and communicate to the cloud.

Also, I have yet to test out the claim that it can last months or years on a single coin cell battery, but will be using it future projects and will be testing this out. There is one difference in the code that supposedly helps the Bluz achieve this feat. The code inside the loop function contains a System.sleep call in the default sketch.

I expect the Bluz to be a worthwhile investment and can’t wait to see what kinds of projects I can build with this low powered Bluetooth LE dev platform. I love that they leveraged the Particle ecosystem and online development IDE as well.

Youtube Video Efforts & LED Mask

Lately I’ve focused more of my efforts on Youtube videos for the side projects that I build. While I enjoy the process of writing blog entries, I also found that I enjoy the visual draw and documentation capabilities that Youtube allows me for the generation process of my side projects. Through the provided analytics I’ve been able to see that the videos I make generate higher engagement, but the value of written posts in providing engagement for text and programming related questions and solutions is undeniable.

The latest video I’ve posted to my Youtube channel is about the making of an LED mask. I have thought about the project in the past and this October I decided to build one using a Particle Photon as the controller. Due to the spacing of the Neopixel LEDs on the strip (60 LEDs per meter) I decided to interlace the strips with an offset.

For those that don’t know, Particle was previously called Spark and I had used their first product, the Core, in the past before the Photon was released. The Photon is evolution of the Core. While much of the platform has stayed the same (both the good and the “could improv), it remains one of my favorite hardware development boards due to its size and capabilities. I’m looking forward to the upcoming release of the Electron that I backed on Kickstarter.

If you want the code for the LED mask, you can find it here.
