If any of the info on this website was useful for your projects or made your head spin with creative ideas, and you would like to share a token of your appreciation- a donation would be massively appreciated!

Your donation will go to my Robotics Fund, straight towards more sensors, actuators, books, and journeys. It takes a lot to continue building these robots, and I’m really thankful of everyone who helps encourage me along the way.

CBC News Maker Faire Ottawa Interview


For Maker Faire Ottawa, CBC news in Ottawa interviewed me about my robots!

You can watch the video clip here, and also mirrored here.


It was pretty neat to hear from people when they were visiting my table that they saw this on the news. When I was going to get some bus tickets, some people came up to me and were all like “you’re the person from tv with the robots”! Yeah! Hopefully some young makers saw the robots and become inspired to build their own. That would be the best.

Here’s a photo of RoboBrrd meeting R2D2! (Photo cred to Britta – thx!)


Big thanks to the Maker Faire Ottawa team for this opportunity, and Sandra Abma @abmacbc for the interview!

New Boards!

Four new boards, open source hardware, timelapse video, and a tutorial!

New Boards!

Big day, we have four new boards! Here is a little overview of each:



RoboBrrd Brain (APMB)

Your RoboBrrd needs a brain! Use this Arduino Pro Mini Breakout board that was specifically designed for RoboBrrd to get it up and running.

Available Now

You can buy these boards on our store, right now.



Timelapse Video

Here is a short video of the making of the boards in gEDA! Time goes by so quickly on timelapse mode…

Watch on YouTube



New Tutorial

We are including 3D printed enclosure ‘sleds’ with each of the boards. It would be very tedious to design these by hand, but there is a way you can export the pcb from gEDA into Inventor. We thought we would share this with you!

Open Source Hardware!

The gEDA pcb files, as well as the Inventor enclosure files are open source!

Nutrition Monitor for the Elderly


This is a nutrition monitor for the elderly. It calculates a malnutrition score based off of body mass index and the daily food intake. The score is then uploaded to a remote dashboard that a guardian can view, and be alerted if it exceeds a threshold.

With the nutrition monitor, a problem can be addressed in a few days, rather than many months.

It is a step in the direction of being able to be more aware of ourselves by using sensors placed in our homes.

Watch it in action:

You can get started making this yourself! Check out the Instructable, NutriModule Arduino library, example Arduino sketch, and the Processing sketch.

MAKE Connected Home Contest

I entered this project into the MAKE Connected Home Internet of Things contest. The prize was a $500 gift certificate at the Maker Shed. We won! Read the article here.


Thank you to everyone who watched the video, commented and shared it with friends, and to the MAKE staff.

It was quite a shock to get a call from Stett at MAKE on Friday evening saying that the Nutrition Monitor won! (My hands were shaking well into Saturday morning.) I will never forget this!

Right now, I’m considering the Printrbot Jr V2. After there are some more purchases in the RoboBrrd Store, we can probably get it!


Just as some background, I saw a tweet about the contest, and noticed that the deadline was really quick. If you read this blog frequently, you might have realised finishing a project very quickly is a struggle for me.

Knowing a gist of what I wanted to make, I researched around about malnutrition. On Sunday (Feb. 2), I dived more into it and learned all about it. There were two references in particular that helped:

Nutrition Support for Adults (accessed Feb. 2, 2014)
Malnutrition Universal Screening Tool (accessed Feb. 2, 2014)

Monday (Feb. 3) it was time to start building. I finished the Arduino library before the hardware was done, then finished the hardware, and created the application plus the remote dashboard. The reason why it’s so tricky to make IoT projects is because of the numerous ‘components’ that have to talk with each other. There are many points of failure. I really lucked out that I didn’t hit many snags.


The one snag I hit was with the conductive foam in the DIY force sensitive resistors not un-compressing fast enough. Instead of the weight being recorded after it automatically detects removal/putting back of the food on the module, a button is pressed instead. The sensors are still a little glitchy, however they can be improved.

Reading the feedback from comments, with some heads nodding thinking it’s an interesting idea, is very motivating. This project is only the first try at the idea. With the future modifications in mind, it will get better.

Future Modifications

- Adding wireless radios to broadcast the data to the internet
This way, there will be no computer needed (except to access the remote dashboard).

- Improving the weight sensors
The conductive foam is very DIY, and this can be done much better to result in more accuracy and reliability.

- Shape detecting mat
Instead of modules, have one ‘mat’ (or plate), that can detect the shapes of many foods placed on it. And detect the weight within that shape area. It will be easier to clean than individual modules.

- Better remote dashboard
Currently the BMI is hard-coded into the desktop application. This should be able to be input via the remote dashboard. Also, ensuring privacy and security of the data is important to be improved.

There are also other interesting ideas suggested, to increase battery life, when to send the data, and maybe switching the place of the module (on the food, instead of the food going onto the module).

One of the obstacles will be the elderly using it / not dismantling it. They may still believe they do not need help, or they may believe it is a spy device by the CIA.

It would be great to run a beta test with some of the future prototypes. I wonder what the feedback would be?

Our future will be full of connected devices. It will be so interesting to have everything synced, communicating with each other, and helping our lives.

Now, I am looking for people who are experienced with health/medical/connected devices. If you know of anyone (or are someone), please email me!

Also, if you are interested in potentially beta testing this (or know of someone who would be able to beta test it), let me know.

Until next time, make something weird or connected, maybe both- weirdly connected!
