On this typical sunday morning, I needed to do some repair work on our dishwasher. The mechanism for soap dispenser was broken and needed a replacement. Luckily i was able to order some spare parts for only € 8,- So this fine piece of DIY would save me a lot of money.
So, you remember the story of The Annoying Dishwasher™? Well, yesterday I defeated him. With the use of some specialized weapons, I removed the Vocal Cords of Hell, silencing the dishwasher for ever.
Do you know the joke about the relay on the ready LED? Well, it didn’t work. As told in previous ‘Annoying Dishwasher’ adventure, it turned out the ready led only turned on as soon as the dishwasher was opened. So the only way I could connect a ‘ready sensor’ to the dishwasher, is by using the original buzzer connections.
So, The Annoying Dishwasher™ finally lost it’s vocal cords of hell and got connected an XBee using some optocouplers. It is time to jump into geek mode (as if we weren’t there yet …), and start the software part.
After I discovered the awesome little ESP8266 Wifi module last week, I spent some extra time to check out how suitable this module is when I want to use it in an ‘Internet of Things’ environment. Or, to be more concrete: Could I use this module to connect my Annoying Dishwasher directly to the internet, without the use of the XBee & Raspbery system?
Exactly one year ago, I started my Annoying Dishwasher™ Project. With this project, my main goal was to silence the annoying beast for once and for all. Today, one year later, I continue this project to make some improvements by applying the knowledge I gathered in the past year.
After test-driving most of the changes I’ve made to my dishwashers schematics, I took a leap of faith, and ordered my first PCBs. Of course I expected something better than my average protoboard, but I didn’t expect something as beautiful as the end product …
