TL;DR: Installing a DIY telemetry led display on a sim rig.
When Googling for DIY led displays for sim rigs, it's very likely to come across TM1638-based modules. They are cheap, compact modules, work with 5v and are very easy to interface. I am using a pin-less Arduino nano …
read moreArrived from Monza this week, after attending the whole F1 weekend.
It is a fantastic experience with great cars (F2 insane sound...),
massive crowd and the fact that the circuit is inside a gigantic park within Monza city,
helps a lot!
When walking around the park you can spot part …
Sadly I only have a few hours left in Phuket before flying back home, however I bring very good memories of this lovely place on Earth - extremely kind people, beautiful weather and landscapes, delicious food.

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 …
For more than a year I've used Domoticz with lua scripts to manage my "superhots garden". For me, the scripting ability is Domoticz's most powerful feature. Overall Domoticz is fine and it packs a bunch of features - most of these I wont ever use and for that reason I felt …
read moreThe time has come for me to upgrade the server where I run this blog. It's not that Debian 6 (squeeze) wouldn't serve me well for another 6 years, however, I'm taking this chance to start from scratch by reviewing every service configuration and start using adequate tools for deploying …

read moreThree years after, I took another step and built another rig. Obviously I planned to improve on the previous and so far, it's mission accomplished! Two of the most noticeable improvements are the feedback system and motion response times.
The feedback potentiometers are now directly connected to the …

After digging around the web for auto-watering systems, I've settled for
a solution that doesn't rely on electricity, doesn't require much
maintenance, is compact and most importantly, waters the plants in a
decent manner (doesn't keep them flooded with water).
It is from AutoPot …
ACUDPClient is a Python module used to communicate with an Assetto Corsa dedicated server. Using its UDP protocol,
real time telemetry, lap timings and session information is pushed to the client.
A few actions, like sending/broadcasting messages are also available.

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 moreToday 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 moreLast 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 …
