2019hackadayprize BICYCLE bike iot Wearables

This project is submitted for

  • Hackaday.com Tip Line
  • Hackaday Prize 2019

This project was created on 05/22/2019 and last updated 10 months ago.

Description

The increasing number of bike lanes and bike racks in our cities shows that bicycles are great for daily transportation. The device in development makes use of Bluetooth technology to connect it to a smartphone running a turn-by-turn navigation software. The application sends commands to the device, these commands are translated into directions displayed via LEDS, indicating the path the cyclist should follow to reach the desired destination, safely riding the bike while keeping the phone in the pocket or backpack during the whole journey.

Components

  • 1 × NRF52832

This would be a new era in electric bikes market there are hundreds of articles on internet about it just s I read on Nano Bảo Vệ Hộp Số 30ml page about this idea and waiting for new updates.

Seems good. Can I test this program for electric bike scirpt. I want to use it for my article blog of electric bike reviews, you can see here https://www.bestelectricbikepoint.com/

  Are you sure? yes | no

Very nice and good looking project! I would love to build one for myself, are you planning to make it Open-Source/Open-Hardware?

  Are you sure? yes | no

André Biagioni wrote 08/30/2019 at 00:23 • point

Yeah! I will post the schematics soon.

  Are you sure? yes | no

pmq wrote 06/11/2019 at 17:47 • point

Nice design! I see that you're using a lipo battery which I'm assuming is in the 3.7V range. How are you powering the SK6812 LEDs? The datasheet says they're 5V.

  Are you sure? yes | no

André Biagioni wrote 06/20/2019 at 22:53 • point

A step-up is used to power the 5V line for SK6812 LEDs.

  Are you sure? yes | no

Rahoon GOAWAY wrote 05/30/2019 at 03:04 • point

Cool idea! II was thinking of making a watch with a similar display (LEDs in a circle instead of moving hands). Did you design the PCB yourself?

  Are you sure? yes | no

André Biagioni wrote 06/02/2019 at 14:58 • point

Yeah! To place the LEDs on the PCB, I calculated all the angles and positions based on the center of the board.

  Are you sure? yes | no

What would be the advantage of this over connecting your phone to the handle bar itself?

  Are you sure? yes | no

André Biagioni wrote 05/26/2019 at 13:25 • point

Good question. Sometimes isn't safe to put a phone on the bike handle bar, and you can enjoy your ride with more safety.

  Are you sure? yes | no

I would imagine that it's better to have a less engaging/distracting device in front of you while riding. No buttons to fiddle with, no temptation to call up another app, less time spent with your head down rather than on the road ahead. Plus, old farts like me struggle to see the detailed GPS maps on a smartphone screen, and this would make navigation a lot easier. Longer cell phone battery life, too - the screen is the biggest power hog on a phone, and having it off would be a huge savings. 

Plus are you going to risk a $1000 phone on the handlebars, exposed to the elements and vulnerable to damage in an accident? Or liable to jiggle free and hit the pavement or go down a storm drain? Pretty tempting target for a thief to just reach out and grab while you drive by, too

  Are you sure? yes | no
