Hello.....

My idea 1 is to  develop the BBC micro:bit North Indicator by using the BBC micro:bit compass as well as 5 X 5 LED matrix.

By using the data of compass arrow in LED matrix is continuously shows the NORTH Direction. which means if anyone rotate towards north to east the arrow at LED matrix will rotate in opposite direction to show the north indicator. and in this i will use one of the push button as reset button to reset the entire north indicator program. Entire thing is run on simple 2 AA battery.

My idea 2 is to develop the BBC micro:bit Mood Indicator by using the BBC micro:bit compass as well as 5 X 5 LED matrix.

By using the Bluetooth Low Energy on board to recive the person mood through mobile app and show it in LED matrix. And in this i will use one of the push button as reset button to reset the entire program. Entire thing is run on simple 2 AA battery.

Micro:Bit is one unique board, not for its fully function and powerful feature, but for its easy to use and easy to learn even for Kids.

I have to admit that this time BBC is ringing the bell for next-generation hero from UK. If so, the vote out of EU is not problem, because UK is still taking a lead.

My propose is to use minimum resources for a fun toy. A BLE controlled crossbow blot to fire a cotton ball stick with paints on head.

The crossbow blot is fixed on one SG90 steering driven platform. Try to use only 3 Digital/Analog pins to control 2-D angle and fire-button to let off the cotton ball stick.

Just try to amuse some naughty kids.

Hello, my idea is to create an watchdog for blind people or for people who have low vision.

All this can be achieved thanks to the small size of the micro bit and:

1. An array of infrared sensors 8 × 8 which serves to make a recognition of the person
2. Ultrasonic sensor for the detection of possible obstacles and of the relative distance
3. bluetooth module with the ability to interact via a cell so that if the person needs assistance have to press a button or connect to the voice recognition and sends its GPS coordinates to a fixed number, this advantage of the GPS module of the mobile
4. pressure sensor to detect the heartbeat and possibly monitor it via your mobile phone
5. conductive liquid sensor, this sensor provides the ability to tell if the visually impaired person is walking on a slippery surface and then take precautions

    3 motors for vibration

    a battery power supply

Possible additions are 2:

• integrate it to the glasses, all the sensors on the front of the eyeglasses in such a way that the micro can process the information in a specific direction and insert the 3 moped vibration on the lateral slats, this is because the type of vibration the person understands if it has a simple obstacle in front, or a slippery surface, or a person
• The second alternative is to integrate it with a stick, this to ensure that we exploit the stick support to proactively report the presence of slippery surfaces and, if desired, you can use a combination of accelerometer, gyroscope and ultrasound sensor to understand if in the next few centimeters, there it will a step, and also because the stick can be integrated flexible photovoltaic panels to extend the life of the device.

I thought to be able to integrate the stick also for a possible energy recovery through a piezoelectric placed under the stick, in such a way that every time the stick is placed on the ground there is a quantity of energy recovered.

I hope I have explained to outline my idea and that it is of interest

Good day

Does anyone know if they still use ticker tape timers in school physics experiments for measuring acceleration ?

If so, just pondering if this could be modernised slightly with the likes of the micro:bit. Either by using the built-in accelerometer, however that may not be so clever when dropping weights, so alternatively by using a punched ticker tape with an optical sensor and a micro:bit as a data logger, giving near real-time analysis of that data without the need for the rather tedious measuring of dots and manually plotting graphs. The 'timer mechanics' could be a simple plug-on shield to the micro:bit containing a photodiode a couple of tape guides and even use the micro:bit's built in LED's as the light source. Might need to mount it on a weighted base to prevent it from flying off the table though.

The likes of Douglas's LCD display idea could provide access to the data or alternatively it could be transferred to the teacher and displayed on a large screen.

I would love to tryout this board and make a health tracker which will record the daily physical activities fitted into the shoes and will sync the data to smartphone or server for analytics. That can again be extended by pairing with smartphone to so that any accidents with the person can be detected.
