What did you build today (Pictures) ?
-
Battery powered MySensors Washing machine & dryer monitor, using LDR's to monitor LEDs on front of the appliances.
Each time a LED toggles, the node wakes from interrupt and sends a message. Easy peasy!
When a device is ready, I'll get a message on my mobile phone :smile:

Still need to stuff it in an enclosure...
@Yveaux So I never fully understood the reasoning behind putting sensors on a washer or dryer. So you start your clothes washing or drying before you leave for somewhere. Is there a reason to know that it's finished when you are away? There is nothing you can do about it until you get home, at which time you could reasonably assume that it is finished. If you are home, can't you just go and check it after some time? Why would you need a message on your phone?
Just curious.

@dbemowsk just to keep the machines running continuously ;-)
And I need to go up 3 stairs to just check on them :hankey: -

Or if someone else than you starts the machine before leaving for the full day, and you come back much earlier and if you don't have a warning you don't necessarily think about checking the washing machine when you arrive home. Here with the warm temperature if I leave the laundry in the washing machine for 4-5 hours without opening, I'm good for a new wash because it will smell pretty bad :(

@dbemowsk
My wife actually fairly often forget to check when the washingmachine is finished, and notice it a few hours later, when kids are a sleep and there is quiet in the house, I will imagine receiving an SMS when washing machine is ready to be emptied will help her, as she is checking her phone often,, even when kids are using all her time -
The value on a dryer is even more tangible: the sooner you get your clothes out, the less wrinkly they get.

@dbemowsk while you are at it..consider :)
The dishwasher can be added as well. My devices dishwasher / washing machine / dryer send messages to all tvs that are turned on. Identifying themselves and invite you to come and clean them :). It comes in handy and absolutely jaw dropping on your visitors.
If you turn on the stove air circulation system in the kitchen... Why not greet the wife with automatically start the TV in the kitchen and play her favourite radio channel at her preferred volume...

Back to the OP topic, I made a micro-usb OTG cable (bottom cable below) that passes through all 5 pins:

This will replace the more fragile cable above it in the next generation of my nRF5 micro-usb programming/debug adapter.It turns out you can't buy this cable. At least, I couldn't find any for sale. Instead, I had to make it myself. Fortunately, Adafruit sells a little DIY kit that helped tremendously:

@NeverDie So many colours of nations offended... Have you thought of going for President ?

Actually, this was the very first time I've used shrink tubing. How could I do it better?
Mostly I didn't want there to be much bending, which might lead to tearing loose the solder connections. I wanted the finished cable to be a "once and done." Now that it's done, the connections should go very easy.

I use raspberry for watching television, movies etc. Today I build raspberry hat to turn on from remote control. Attiny85 recognizes programmed remote code and by optocoupler short circuit on pins.
@scalpel how do You program the ir code for the power button ? can it be programed from the linux running in the rpi ? or it is just hardcoded into atiny code ?
-
@scalpel yeah, I did this kind of project also and I wonder if there is a software for that :) It would be fun to be able to set the wakeup ir code from the linux os, with for example i2c or 1-wire interface.

@sincze hi, could you elaborate a bit more the TV messages, do you have any link with more info? Was that the LG tv with Mqtt that was mentioned on the forum?(or I mixed forums)

@dakipro we use kodi on al lgl tvs. The libreelec TV box has cec and can turn on the TV via hdmi. If TV is on I am able to control the volume via the LG webserver. Kodi (api) can display the notifications for Me :). Not that fancy but it works like a charm.
