National Maker Week (June 16 – June 22)

June 21, 2017

 

This week is being celebrated as the National Week of Making by Nation of Makers – a nonprofit dedicated towards supporting the maker movement in the United States.

When the new administration took charge of the White House in January 2017, they took down all pages related to the maker movement in the United States. It is not known whether these pages would be restored in the near future. I learned this from watching Adafruit’s Show and Tell and I also learned that Nation of Makers decided to take lead on driving the maker movement.

They are encouraging makerspaces to conduct maker townhall events by offering grants to them. I promised myself to celebrate this week by building something useful (another blog post coming soon!).

I also wanted to share some interesting news to celebrate this week. Digi-Key and Adafruit announced that they will be donating a Circuit Playground to Girls Who Code for every Circuit Playground sold on their website. Check it out!

I also recommend checking out this week’s Ask an Engineer episode from Adafruit (shared below). Happy Making!


Etcher – A tool to flash an SD card for the Raspberry Pi

May 12, 2017

We came across a tool called Etcher from Resin.io.  It is a tool meant to flash an image onto an SD card. This is especially useful to quickly setup your new Raspberry Pi. It is a one step process where you can select the image and flash the SD card for your project.

We put together a video that shows how to flash an image for your Raspberry Pi:

 


Raspberry Pi Zero Enclosure – 3D print time lapse!

May 7, 2017

I wanted to document my projects in vivid detail. Recently, I 3D-printed an enclosure for the Raspberry Pi Zero W. I recorded the printing process. The enclosure consists of two halves. The top piece broke while trying to remove it off the bed. In my second attempt, I printed the top piece separately and managed to remove it carefully.

Psst: I am learning to make good videos and I look forward to hearing your feedback

Webinar on IPv6 over BLE

April 24, 2017

Design News is conducting a webinar on Implementing an IPv6 network using Bluetooth Low Energy devices (BLE) and a Raspberry Pi. The webinar runs for 5 days for 30 minutes. The webinar demonstrates the implementation using a Raspberry Pi 3.

It appears that this following development kit is necessary to follow along with the webinar. I will share my experience after watching all the webinars. The webinars are recorded for posterity.

Jaguarboard – Yet another (not so impressive) SBC

December 29, 2015

I usually back Kickstarter projects(in the DIY electronics domain) that peek my interest. I recently backed the Pine A64, UP and the Latte Panda boards but the Jaguarboard is not one of them.

I usually look for a cool feature that would enable me to build a cool project using the backer reward. For e.g. The Latte Panda comes with onboard Wi-Fi/Bluetooth. It has an ATmega32U4 microcontroller that enables easier interface of sensors.

The Jaguarboard failed to impress me for a couple of reasons:

  1. Lack of sufficient GPIO count – They provide access to only 4 GPIO pins. I usually make use of more than 4 GPIO pins in my projects. However, it does come with an I²C port which could be used to expand the GPIO capabilities.
  2. Incompatible with the Raspberry Pi/Arduino add-on boards – It is not possible to port Raspberry Pi/Arduino projects that makes use of an add-on board to the JaguarBoard platform. It also doesn’t make sense developing expansion modules for the JaguarBoard as the lack of a broad user base is a distinct possibility.
  3. Comparison of specs on the campaign page – The campaign creators have compared the specifications of the board to the Raspberry Pi Model 1 rather than Model 2. The Raspberry Pi Model 2 comes with 1 GB RAM while Model 1 comes with 512 MB RAM. I think that is not a fair comparison.
  4. Unrealistic campaign schedule – In my opinion, the promised delivery date of the board is a tad unrealistic. They promised to deliver the boards by January 2016. The Kickstarter campaign itself ends only on January 22, 2016. As far as I know, Kickstarter takes at least 10 days to transfer the campaign money to your pocket. This puts the campaign roughly in the first week of February. Unless the campaign creators, plan to ship the boards using money out of their pocket, this is not possible.

They also have not released any planned timeline of the project. This is possible only if they already have a stash of boards manufactured, packed and stored in a warehouse.

In summary, I am not impressed by the JaguarBoard Kickstarter campaign.
