MOD-IO got beautiful DIN rack plastic enclosure from Giuseppe Mascolo

We noticed this Twitter post from Giuseppe Mascolo @linuxpeppe
He designed beautiful plastic enclosure for MOD-IO which could be attached to DIN reel:

the design files are uploaded to Thingiverse


New Open Source Hardware board released: BB-TB6612 Dual DC motor controller with PWM to drive small robot cars with 12V up to 1.2A motors

BB-TB6612b

BB-TB6612 is dual channel DC motor controller board it is nice add on for the Robot chassis we have ROBOT-2WD-KIT , ROBOT-2WD-KIT2 , ROBOT-2WDL-KIT , ROBOT-3-WHEEL-KIT and can drive these gear motors: MG-6-120 , MG-6-48  and MG-6V-1:380

The digital logic can be from 2.7 up to 5.5V. The motor voltage can be from 2.5 up to 13.5V.

PWM, CW, CCW, brake-stop, stand-by modes are implemented.

 

Gear motors and accessories for building robot cars are in stock

MG-12V-DE5

We got some new toys in stock for robot builders. The MG-12V-1:100-DE and MG12V-1:380-DE are gear motors for robot cars, working at 12V with 78 RPM and 300 RPM . Both have digital encoders which give two channel feedback for the rotation speed, used for identifying the speed and rotation direction. The MG-12V-1:100 and MG-12V-1:380 are lower cost alternatives to those motors but without encoders.

These motors can be attached to a flat surface with MG-FIX.

MG-FIX

The MG-WHEEL-43mm are rubber wheels with diameter 43mm and a width 19 mm which attach directly to MG-6V and MG-12V gear motors.

The MG-WHEEL-65mm is rubber wheel with diameter 65mm and width 25mm. It requires a special MG-COUPLER.

COVID-19 quarantine projects to try with eduArdu while at home :)

Keep social distance while drinking with friends 🙂

No this is not an eduArdu project, but it is still fun to implement.

The eduArdu Social Distance project is using the onboard Ultra sound distance meter and beeps with its buzzer when someone comes closer than 1.5 meters from you.

The eduArdu Infrared Thermometer project uses MOD-IR-TEMP and scans surface temperature from a distance of few centimeters. If the read temperature is above 38 C it will beep with the buzzer to warn you.

eduArdu-IR

Both projects are easy to implement together with your children.

Programming with open source hardware educational board eduArdu and Scratch 3

Screenshot from 2019-07-29 14-52-10

New demo code which transforms eduArdu in Makey Makey and tutorial how to use with Scratch 3 is uploaded to GitHub.

Here is the result from above code:

eduArdu OSHW educational board new demo and tutorial updated on GitHub

eduArdu-3

The eduArdu-BotKit demo is uploaded on GitHub. This code control the robot with sound.

New LED_Matrix_Light library is uploaded. It contains only Clear, SetPixel, GetPixel, ClearPixel, Line, DrawRectangle, UpdateMatrix functions and do not take lot of memory like the LED_Matrix library which contains text scrolling and fonts.

Two more demo for capacitive buttons are add. One make sound depend on capacitance, the other prints the value of the capacity measured.

Programming eduArdu with Arduino explains how to install Arduino and some basics of programming for beginners, like what are arrays, variables, etc. It may be used as practice of what is learned in C/C++ class in school.

eduArdu-BotKit transforms your eduArdu in small bot

eduArdu-4

eduArdu-BotKit consist of two continual rotation servo motors, two 32mm wheels, ball wheel and converts eduArdu in small robot:

Here is small video clip of small demo how to control eduArdu robot with clap of your hands.
