Hello yatz,
I know this post has been around for more than 3 years.
But have you found speakers/trainers for your Arduino workshops in Tagum, for the past years?
I will be coming back to Davao 1st quarter of 2017 and start conducting a series of Arduino, BeagleBone Black, and IoT workshops for students/makers/professionals.
I am Davao-born but was working in Manila and Singapore for the past 8 years.
You can drop me an message here if you are still interested: ianfellarioza@gmail.com.
Thanks,
Ian
