As explained in my last post, I moved my indoor greenhouse to the exterior but wanted to keep monitoring temperature and humidity, without relying on wall outlets.
I started with a 10AH power bank attached to the esp8266 circuit and it lasted a few days before I had to recharge …

Our weather is great here in Portugal and as such, I am moving the plants I had in a growtent for more than a year, to an exterior greenhouse. I used to actively control most elements inside the growtent such as light, temperature, wind and humidity …

A greenhouse project that I've started where light, watering, air extraction, resistors, fan are controlled automatically based on time of day, temperature & humidity sensors or simply gravity (for soil watering). All of it is connected to an Arduino and a Raspberry Pi. The Pi runs controller logic for all …read more
Today I've finished this project! A classic-looking game cabinet. The project included the design, construction, installation and configuration of all the components. Modesty aside, it's looking awesome! :)read more
Last week I've built a small, 250mm sized, quad copter, using a KK2.1 evo flight controller. One great feature of this FC is the ability to tune flight performance on site, using it's built-in LCD display. It's really helpful, specially when you're learning PID tuning!
Besides the learning aspect …read more
