ESP32

I just got my ESP32s from Bangood.

Temperature Sensing I2C IC modules that accurately measure temperature.

2 x 12V 80W Auto Radiator fans to be installed as ceiling fans. Require speed controlled PWM outputs.

Ceiling lights.

Control of reversible motor to drive bed mechanism as well as opto flag to count the revolutions on the lifting winch spools.

#214 New: Easier ESP32 installation in Arduino IDE (How to)

Disappointingly I couldn't get the USB port to open either in Ubuntu or Windows and on neither of the two ESP32s. 

 The USB to UART is made by Silabs and I tried using the drivers in Windows to see if I  could get the USB to the PC communicating.  I installed the drivers. No apparent change. I deleted the 210 chip series  USB drivers rebooted and unaccountably the Com ports began to work.  

Dodgy Connector.  Found one USB cable that worked where the others dont. Possibly the OB Micro USB cont quite to spec. Nasty.

Lovely Spot

Weathered granites and white trees in open bush. Some sign of prior visits from the Clan of the Brown Butterfly but not too objectionably so.

 

The Garmin 72H is a GPS and no more. No lifestyle "hanging by your testicles from a karabiner in the Rockies" statement or any of the other marketing bullshit. It has a display that can be read on moving motorcycle and has buttons so it will work in the rain. Only cost a cuppla hundred bucks if memory serves.

The handrails finally fabricated and fitted. Feeling SO safe!!

A large camping ground where (I assume) the Avon Decent is staged.
It is only 24 H stay and the Ranger will come kick you out despite the place being deserted.

 

Current Sensor

30A New Range Current Sensor Module Board For ACS712

Descrition:

The current sensor chips: ACS712ELC-30A
The module can measure the positive and negative 30 amps, corresponding to the analog output 66mV / A
Pin 5V power supply, on-board power indicator
Using gold plated circuit boards
No test current through the output voltage is VCC / 2
Size: 31 x 13mm

This will hook straight to the ADC GPIOs in the ESP32. 

ESP8266 220V 10A Network Relay WIFI Module.
I have two of these.

Arduino "Hello World"

Well not quite. I did a Morse Code snippet instead.

Jan 2018 Snaps

The bed is an appalling structure, bolted to the wall @ 1metre. Inner spring mattress and conventional truss and slat design. Would like something more elegant in terms of padding and more ergonomic in terms of space. Either it folds up @90 against the back wall or gets lifted straight up to the ceiling. The space underneath is reclaimed as living space and the structure of the bed base becomes  ; speaker cabinet , VDU, electronic test equipment etc as appropriate to it's positioning. i.e. overhead or perpendicular against the back wall.

 

View from Bed. 

Sink and Roadside (Starboard) Door.

Top Unit of two stacked Engels in front of the wall separating off the shower compartment.

Aft Head level section of the workbench.

Turn your head 45 Degrees forward to get this view.

The R&D Pi on the bench - look down.

The R&D Pi Entire rig on the bench - look down and 45 degrees forward.

Standing in the Galley looking Aft. The large screen HDMI TV (Monitor) is bolted to the panel affixed behind the bread maker.

The view from the sink looking to the curbside (Port) .

A crisp skinned huwhite loaf freshly beeping and emerging.

The view from the Work bench, at head height, over the HDMI Monitor. You are seeing a Laptop (Lenovo) that is running the network. The Car "Radio" that drives the Audio system - mostly Bluetooth.  And a few Dinosaurs.

Same set from 45 degrees stepping toward to spine of the truck.

Ditto - close up.

Ditto - step back.

Composting Lavatory - Not optimal. Needs reengineering both Bioloical and Mechanical. Still acceptable performance. 

Power board and Pi openHAB module.

Forward Bathroom bulkhead looking Aft

Vietnameese Girls are not white enough.

A locals market in Hoi An. It is only a half mile or so from the CBD but is still rural. A typical drive into the country in terms of distance would get you into Thailand.

Vietnamese women love to cultivate white skin. They hide away from the sun with a Nosferatu like obsession and in doing so dress like some Off World Warrior except their Armour is festooned with Hello Kitty, Flowers and Bunnies, leavening the effect. I was told this wasn't some hayseed rural quirk - all Vietnamese women are equally prone to dressing like this during the day.

The food is so fresh that food poisoning would be out of the question.

Even the vegetables seem to be wriggling.
