Time for an update on the led clock project by me and Wouter Jansen. A lot of things have happened recently; We’ve send out a call to action to all the people who’ve shown interest in investing into the first prototype run and the we’re happy to announce that our first prototype run is not only …
Lighten up your ESP8266
For a workshop I’m giving at my employer I’ve been wanting to interface a nice NeoPixel (WS2812) LED ring with an ESP8266. Using the NodeMCU boards without the actual firmware provides a nice platform that gives a small packages, with breadboard ready pin spacing & USB to serial chip. It has been a struggle to …
ESP8266, MQTT & SmartConfig
Having done a lot recently with the ESP8266 and the excellent MQTT firmware by Minh Tuan I found that there was one mayor thing missing in the whole headless module setup; An easy way to configure the ESP8266 while it didn’t have Wi-Fi yet. Looking around I found some code made by YoungBuger on GitHub which is basically …
Eurotrip 2015 – Neuschwanstein
Our last stop on the Eurotrip was Neuschwanstein Castle, in Germany. One of the greatest castles in Europe – and one of the world’s foremost tourist attractions. Part theatre, part fairytale, Neuschwanstein Castle embodies the soul of King Ludwig II of Bavaria, popularly known as ‘mad King Ludwig’. Neuschwanstein was designed to be a hideaway …
Eurotrip 2015 – Ljubljana
Our fourth stop in the Eurotrip was Slovenia’s capital, Ljubljana — with a lazy old town clustered around a castle-topped mountain — is often compared to Salzburg. It’s an apt comparison, but only if you inject a healthy dose of breezy Adriatic culture, add a Slavic accent, and replace Mozart with local architect Jože Plečnik. …
Eurotrip 2015 – Bulgaria
Bulgaria’s central heartland is vital to the national consciousness, for its role in the 18th- and 19th-century National Revival; this legacy lingers in the period architecture of Lovech and Koprivshtitsa, and at battle sites such as the forested Shipka Pass. The area around the Central Mountains contains two mayor mountain ranges: the Stara Planina and the Sredna …
Eurotrip 2015 – Istanbul
The second stop on the Eurotrip with Radost was Istanbul, a fascinating city built on two Continents, divided by the Bosphorus Strait. This is one of the greatest cities in the world where you can see a modern western city combined with a traditional eastern city, it’s a melting pot of many civilizations and different people. From the …
Eurotrip 2015 – Vienna
This year, me and Radost made a trip through Europa. Our first stop on the route was in Vienna. Having never been to Vienna in my life before I was eager to experience this capitol of music and imperialism. Having booked a great hotel in the middle of the city, we were able to explore …
Iceland
[su_quote cite=”Stephen Markley” url=”http://talesoficeland.com/”]The problem with driving around Iceland is that you’re basically confronted by a new soul-enriching, breath-taking, life-affirming natural sight every five goddamn minutes. It’s totally exhausting.[/su_quote] Last year I had the chance visit one of the top destinations on my bucket list with my friend, Eveline. Iceland is a land sculpted by …
Allow me to Interrupt
Recently I had some problems with my I2C brightness sensor on my clock. It messed up the main routine of smoothly drawing the clock at a rate of 30 updates per second. Analog was a solution to this, but it didn’t solve the main problem of the design. Interrupts where the way to go if I …
