Wildlife UAV Challenge

While attending the PDXElectroHax meet up I was told about a project that was getting underway to do with building a UAV to help protect rhinos in South Africa from poachers.

There was going to be a kind of kick-off meeting on Saturday and would I be interested in attending it?

PDXElectroHax Meet Up

I came across a group called “PDXElectroHax” on meetup.com. They meet only once a month, however the upcoming meeting was the next day, so I decided to attend. It’s a relatively new group – only started about three months ago. The meet up was at an very interesting place: a “maker space” called ADX where […]

I never got around to using it to any significant degree and that always irked me. The kit was not cheap. This Holidays I was looking for some kind of fun project to […]

Trickle-In Effect

As I am starting again from scratch, I’ve been shopping around on the internet for equipment and components.  I had a book I impulse bought, called “Make: Electronics” by Charles Platt, that helped me compile a list of things I need. A surprisingly long list it turns out. A lot of the items I could […]

Charging the Flux Capacitor

I’ve decided to get back into electronics again as a hobby… Unfortunately there’s not a lot of free time… and what little there is will be sporadic at best. Still, I’d like to make good head-way with the endeavour. I’d hope that by keeping this journal it will help focus my mind, as well as […]
