I’ve got C-Bus lights at home and I wanted to tie them into openHAB so I decided to (surprise surprise) use a Raspberry Pi to bridge the gap. I already had a USB to RS-232 cable, and the C-Bus setup had a Serial PCI Module, so I could dive straight into it. Here’s what I did to get C-Gate running.
I finally got around to assembling my ESP32 Feather-compatible board. (A few days after Adafruit released theirs. Didn’t know they had one coming) Booted straight into Espruino, connected to wifi, toggled pins. Very cool having it work first try!
Espruino is awesome and here’s a way to help fund it!
A bit unfortunate that I’ve got a stack of Wi-Fi HATs for the zero already, but I’m definitely happier to have this option. Should be good.

Cool product! I was actually looking for something like this a while ago, good to have a source now.

It’s a Bluetooth microcontroller running Espruino, a JavaScript interpreter. Firing it up and running some code was so fast and easy. Once I removed the battery tab, I opened the ide, selected the puck from the connection list and then hit upload with the default blink code. This is easily the most polished kickstarter I’ve helped fund.

Just saw this on Hackaday, very nice technique for driving LEDs. I can’t believe we haven’t seen it before. It uses tricks with voltage drops to drive n²+2 LEDs with n pins, instead of the n²-2 that charlieplexing yields or the n of one-to-one connections.
13 brand new boards to assemble! All the components for them arrived in the mail this week, so I’m ready to go. Might take a while though…
