Some weeks ago I talked about the Magic Home LED Controller as I was adding support for it in my ESPurna firmware. At the time a user pointed me to the H801 Led WiFi Controller by Huacanxing. The user in question (Minh Phuong Ly) even did a pull request with some preliminary support for it. So I decided to give it a go.
The H801 is a 5 channels controller that you can find for about 9-10€ at Ebay or Aliexpress. It’s slighly more expensive than the Magic Home Led Controller (you can find the later for 7€ at Aliexpress) but it also is quite different from the insides…
I’m having some busy weeks again and the blog is suffering from my absence 🙂 I had a bunch of comments to accept (please remember all comments are being moderated). And even more projects pending (including a new version of the ESPurna firmware). But I just wanted to let you know that I will be at the Barcelona Maker Faire next June 17 & 18.
There are so many ways to tell the time. DIYers have been doing clocks since the Ancient Egypt (obelisks lacked portability, thou). Every modern maker has a clock amongst her first projects. I have done some myself, including a fibonacci clock, a wordclock with a fancy green matrix effect and an unreleased project that hopefully will see the light someday soon.
But recently I came back to the idea behind the wordclock before, to extend it in different ways:
Replace the ATMega328P with an ESP8266 (NTP support and user interaction)
Smaller sizes (8×8 LED matrices)
Smaller PCB, less buttons
Add buzzer for alarms
Replace the 3D printed part with a wooden grid cut in laser
Completely closed enclosure, better presentation
Fix some issues with the original board (like the lack of a beefy capacitor across the LED matrix power lines).
Last February 7 I attended a workshop at a the SokoTech in Barcelona to assemble my own Fenderino, the coolest guitar ever (my knowledge about guitars is very limited, so take this sentence with a grain of salt).
The guitar is actually a shield for the Arduino UNO and has been designed by the people at abierto.cc, an initiative aimed to provide open(-sourced) tools for educators, created amongst others, by David Cuartielles, co-founder of Arduino. The shield is inspired by the works of two very good friends of mine: Marc Sibila (@marcsibila) and Jordi Divins (@jdivins). You really should be following these guys, they are doing very special things as Instròniks.
After a busy month I decided to spend some energy on doing hardware instead of software and the result was the ESPurna board I posted about just yesterday. The goal was to have a device based on the ESP8266 I could fit into my house wall gangs, with an SPDT relay to work with multi-way switches and power monitoring using the same IC the Sonoff POW uses: the HLW8012.
As a side project today I’ve been searching on the box of the TODO projects and I have rescued a KEMO STG15 [Ebay] plug housing with socket. These sockets are somewhat expensive and really bulky but the good thing is that there is quite some room to fit some electronics inside, but not a Sonoff board, too big.
