We talked about Otto micro:bit, possible shields to use.
Df mini delay bug solved.
Good speakers to use for audio player.
OLED mouths and eyes for Otto
Visual studio for collaborative text coding
Ivan showed cool games with Otto scratch
Claudio Gasparini show us his cardboard Otto that he will post here.
Esp8266 and esp31 libraries and new blocks for iot.
Servo library
Ideas for education in robotics including more out of screen activities, tangible programming robots and games.
Did I miss something? Nicolas Piers Kennedy
What is happening with the gamepad is that getting shelved or it actively being pursued now or later?
How soon before the next release is available?
Those are my three questions.
Small is sometimes better unless you have big fingers. Then you wan't more grip for your buttons and case
Would it be safe to say then. ( about the multiple displays). If it can be done in a sketch, mutiple oleds, then it can't always be done in blockly? There are videos of sketches using 5 oleds off a nano or uno. Just trying to get a bearing on what is possible or not if I see it done on you tube or somewhere on the internet.
Once I get a base to work from it makes the tasks of finding or questioning what is possible a reality.

I was disappointed to learn just how many "brains" are close sourced and sealed up like a scroll.
ESP 32 is RAM * 250, program memory * 100, clock speed * 10 * dual core + wifi & bluetooth + loads of hardware peripherals + RTOS to run parallel tasks. Another world...
Nicolas case wise, do these come with shields, can they be used the same as the nano when it comes to size and dimensions. Are there cheap knock offs of this esp? Eds cost quite a bit compared to a nano every. Will they have universal boards to use or will they closed source circuitry ?
Can you point to me on amazon what the boards you have in mind you plan to use? I would like to take a look and see if I can find a model on grabcad. thanks.
Is this it?

This one has https://www.amazon.com/Aokin-ESP-WROOM-32-Development-Bluetooth-Microcontroller/dp/B08NW6K357/ref=sr_1_17?dchild=1&keywords=esp+32&qid=1622385489&sr=8-17a tiny camera
There are also board in Wemos D1 mini format (but it seems no IO/servo board for them), or ESP 32 in Arduino Uno format, in all cases the pinout is public and there's no need to investigate like on the tokymaker (which is not that hard to understand anyway).
It's a bit bigger than a nano in the "NodeMCU" format, but the same with IO adapter board. And no need for "knock off" as it's cheap by design, a module is <5$ and the module on a development board (like on link above) is <10$ and easily found <5$. Cheaper than nano + bluetooth adapter.
And it's also not too difficult to start from the ESP32 module alone (including ESP32 IC, 4MB memory and antenna) to design a custom PCB that can then be smaller than nano+shields available online if you want to go the open source hardware way. I made one for another project and on a 5*5cm surface it has ESP32 module, USB port + battery connector + battery charger with power path, step down, 240*240 pixels IPS LCD, accelerometer, IO Extender, connector for plug-in boards, SD card reader, SPI flash chip, neopixel, NRF24 connector, 3-way navigation button. So without the unnecessary stuff for an Otto there's enough room to connect servos and end up with a board much smaller than what we have now with nanos and no need for any bluetooth module, IMU sensor etc
Places like adafruit, sparkfun and digikey are price gougers imho.. It might be the same or different over there. But here it is very limited, and very closed source.
I have been wanting to point out too.
Is the hype greater than the facts.
ESP32 has been around for a few years, there are different versions of ESP32 now but if you stay on the initial one it's very well integrated with Arduino, except the dodgy ADC everything advertised is working and you can effectively do thing like use a camera to do face recognition, do speech synthesis outputting data on the I2S peripheral etc And no problem with its wifi capabilities, it's used in many wifi modules, including arduino boards like the nano-33 Iot, which end up having a wifi module much more powerful than the main microcontroller...
The only drawback is the power consumption, but on a robot with hungry servos or stepper motors, LCD, led arrays etc it's not really an issue IMHO.
For PCA 8965 there are cheap breakout boards, you just need to connect power and I2C and you're done, having a specific shield for each MCU/dev board is not necessary.
ESP32 and Espressif (parent company) won't disappear overnight they sell decent products, increase sales year after year and are profitable.
That's so very true. I remember back when kk2.0 boards were hackable, open source and then programmable with a usb hub. We flashed new updates on them all the time on these. (Drones)
The came along DJI (China). They flooded the market in the cs shows, bought up thier competitions at cheap prices, then hooked a deal with the faa. Now you have a closed ccd and you have to pay to fly.
That is why I am believer in graphical interfaces like Blockly.
Fast results, cheap parts and just your imagination. Well that a good printer.
Nicolas I learn from history and I question everything.
Sorry for the long lessons. (posts)
I reached to her through sparkfun with otto. She wants nothing to do with us. Least that what direct email said.
