Hi Guys

I am very happy that finally had time to compare these two new expansions after soo many iterations and thanks to Piers Kennedy calibration it was a breeze to make them walk properly. It is funny that after calibration they both are steering to the right, I must have done something wrong? Please let me know.

On the left there is the Otto esp8266 as promised testing the walk, as you can see it walks quite decent even with the servos at 3.3V I am using an ubec+lithium as Bill SCHONFELDER does in his robots. Anyways I want to leave the esp on hold until we properly document all the new expansions and finish the design for wheels module. But if you like it, feel free to explore it.

On the right is the humanoid expansion I think is gonna be a hit and with the hammer it looks really cool! Can't wait to start some battles or make it play some drums?

This biped races are gonna be fun for the tournament

Check this out, this Otto humanoid works seemingly with OLED libraries

min 25 explains how to optimize variables but i recommend to watch it all, this might be a solution to leave room for more components even with nano clones.

Thanks to nishana nibha she shared the code here

We are not the only one making Otto compartible with ESP and that is awesome!

I hunted the repo for you Nicolas https://github.com/pass810/Otto1_library

Piers Kennedy this Japanese seems also using Raspberry now

Bill SCHONFELDER i know you will like the use fo the color LCD 😀

Alright guys check this out!

Making a super simple sound level display, made in Blockly 😉 very few blocks. Is this what you were looking for Bill SCHONFELDER ?

I am still playing with multiple type of sound sensors but you can expect something like this, please let me know, otherwise is as Piers Kennedy said, "not worth to ask too much to the poor nano". We could add a fast hartley transform library for a realistic analyzer but will be for one specific application.

When you want to imitate the visual, it is all possible with blockly 😉


We should make a project for all things we can do with OLED

Hi guys

Just a simple example of how we can make nice emotional OLED mouths for Otto with the new expansion.

You can see the proportion is quite ok, we can always put it higher or use a bigger OLED display

I am just using regular geometric shapes instead of bitmaps, in this easy way we could have less memory for nano and more control of the size (mouth opening), when combining it with the cool dfmini speech you guys made.

Let me know what you think.

Alright Who is ready for a second online meetup?

Otto Blockly improvement progress #2 "Servo Blocks"

So as a continuation of improvements on the back end for Otto Blockly this week behold the new generation of Servo blocks ;P + map math block + better input and output blocks for general arduino purposes.

I bring together lots of needs you guys have been requesting and the video of Piers Kennedy to make the microseconds servo control

Next we are gonna tackle DC motors and make them work quick and fast with blocks.

Suggestions welcome.

if you wanna test now the new blocks do the following steps
1. go here https://github.com/OttoDIY/blockly/blob/master/www/blocs%26generateurs/motors.js
2. Right click on "Raw" save link as... (that will download just that file)
3. Use that file to replace the one installed in your computer in
C:\OttoBlockly\www\blocs&generateurs
4. Press F5 in Otto Blockly or restart the application, that will update the blocks

Repeat same step with these files:

new inputs and outputs look update

for map block you need to update

Let me know how it goes

Otto Blockly improvements progress #1 "DFmini Software Serial"

Hi guys good news! i just updated the MP3 DFMini block setup/init to convert into Software Serial libraries and to trigger sound events.

If you wanna try them before the new version comes (we still have a long list of things to do 😃) you can just simplify replace these 2 files in your local installation folders:

The blocks code update
https://github.com/OttoDIY/blockly/blob/de3a7ddd1572a8809ccc28ab13eb50f4bf94125a/www/blocs%26generateurs/actionneur.js
goes here C:\OttoBlockly\www\blocs&generateurs

The English update
https://github.com/OttoDIY/blockly/blob/1061420af70ef30574dd10fb2923194436b369d9/www/lang/Arduino_en.js
goes here C:\OttoBlockly\www\lang

And the toolbox update
https://github.com/OttoDIY/blockly/blob/de3a7ddd1572a8809ccc28ab13eb50f4bf94125a/www/toolbox/toolbox_arduino_all.xml goes here

Here there is a video of the single booster using a small 16340 lithium cell from 3.7V to 5V to power a humanoid alike Otto with 6 mg90a servos at the same time in some movements (the metal ones) including a neopixel matrix 4x4 in full brightness.

I also tested the module separate and it powers more than 2 servos at same time Piers Kennedy Bill SCHONFELDER

Timm H. Try testing them out separate from the nano
