Oops. Connected to 24VAC instead of 12VAC. The ESP8266 survived but from there back is toast!

Charcoal Chicken Rotisserie

Gave the rotisserie a second go with charcoal again. Turned out great!

ESP8266 Controlled Remote PSU

The remote power supply for the cherry lights and the RGB garden lights is now complete. This will eliminate one sonoff which was previously used to control the cherry lights on the mains side.

Charcoal Rotisserie Mod

I took the grill out of my gas BBQ and put some charcoal baskets in to try out my new rotisserie. It turned out well, bit of a learning curve with the charcoal though...

Massive Fish

Caught a massive fish...

Garden Lights PSU

Created a power supply controller for the garden lights to turn on and off the set of standard cherry lights and supply the IOT garden lights with power also. Each (24vAC and 12VAC) are controllable via relays. It also has a rectifier and DC-DC convers to supply 5V and 3.3V for other projects and the ESP8266 controlling the PSU.

Bacon Wrapped Chicken Thigh Fillets

Bacon wrapped chicken thigh fillets with mash and veg. This was a real crowd pleaser.

Today I converted the garden lights to run off AC rather than DC which I think will work out better. I've added a bridge rectifier and smoothing cap to each.

24 Disk RAID 0 Roulette

Created a 24 disk RAID 0 for S&Gs on the Supermicro storage server. It has a ASR-52445 in it.

Today I got another set of component drawers, the same manufacturer as the other set, just with larger drawers.

6 Racks of Ribs on the BBQ

6 racks of ribs on the BBQ =) This time I cheated with the rubs rather than making my own usual recipe. McCormick Tenesee Smokehouse and Slown & Low Texas rubs.

For the first time I blew up an ESP8266. Which is difficult to do, they are pretty robust. This one is kaput though =/

The remote lock/unlock for the car has these weird surface mount buttons on them. They have a rubber plunger and they are not tactile. These needed replacing because they started to fail. I took a gamble on some surface mount tactile switches from ebay (a few bucks for like 20). They fitted well and give you a much more obvious click feeling when you press.

Sonoff Flashing - 5v injection

I found a place to inject 5v so you can flash the sonoff and test the relay is functioning.

iTead Sonoff Logo

This evening after a session of DarkMatter great progress was made on the SonoffMQTT project. This project aims to replace the firmware on a Sonoff with custom firmware so that it is accessible via MQTT instead of the supplied eWeLink. Having it available on MQTT means it will plug directly into Home Assistant and will be cointrollable from there. After soldering some headers into the board, I was able to power it externally (not mains) and flash it using Arduino IDE.

Flashing Sonoff with custom firmware. To do this you have to externally power the Sonoff with 3.3v via the header. This, however, does not allow you to operate the relay because the coil is on the 5v relay.

Arduino Logo

A pretty productive day. The code has now been refactored to accept simple non-json type commands on specific topics ie <uuid>/relay/0/set. This allows the relays to work with the "switch" function in Home Assistant.

MQTT Home Assistant Sensors

After some refactoring of the dual relay board code, it's now reporting temperature, humidity on MQTT topics. This means it will work correctly with Home Assistant.

The storage server got an upgrade to E5-2620v1s.

Updated design with larger resistors and the missing silk screens added.
