    Joby and his team was able to complete the project. However, it took much longer than expected and also cost more than originally anticipated. We would choose not to work with Joby again over this unexpected additional expense and time delay. We did not expect this as Joby had great reviews prior to this project. We assume that he was not familiar with the subject matter at hand and bit off more than he could chew. We would be okay with rehiring Joby for a project he was more familiar with.

    IGNORE THE COMPLETION RATIO. The duration of the project was extended due to my inability to constantly be engaged with the project due to other commitments meaning Joby had to wait throughout until I responded. This has added to the timeline of the project and unfortunately had a negative impact on his overall completion ratio, so he is not to blame for this I am. Joby did an excellent job with no delays on a very demanding project applying existing technologies in a totally different way. He has gone beyond what was requested and his knowledge and expertise in applying these technologies has made the project a massive success. We will embark on the next phase of development and I have total confidence that Joby can deliver what will be required and look forward to carrying on working with him in the next phase of work. YOU MUST HIRE THIS GUY!!

    I have a patent on what is called a smart glove or a wristband to be used by cyclists to improve their visibility and communicate their intentions more clearly to drivers. It uses a small accelerometer that determines the cyclist hand signals for turning and stop and activates LEDs within the glove. I have a prototype board design that uses a pic microcontroller and is programmed currently using PicbasicPro. The design functions well but has some limitations with the use of a glove and I would like to adapt the electronics into a wristband. The wristband would have multiple LEDs that could be seen from front and back. I would also like to charge via usb and be water resistant, if not near waterproof to hold up with sweat and rain. I also want to look at some type of wireless or Bluetooth communication to activate remote led light indicators that can act as turn signals and brake lights.I am open to other microcontroller platforms such as arduino. I have the existing pic source code, prototype board layout, prototype PCB design for a starting point. The current design uses a MEMS accelerometer.The first part of the project would be the wristband with LED design and the second part would be the addition of Bluetooth to the wristband and a LED Bluetooth activated signal. The wristband design itself is open for discussion. It could be a flexible strip of very bright LEDs in a silicone translucent jacket with either a flexible stretch portion or an adjustable clasp like a watchband.We would need a confidentiality agreement for more discussion. I would also like some design input as well as Prototype and possibly manufacturing quote.. I can provide a concept rendering once the NDA is signed. The rendering is meant for concept and may not be able to be manufactured exactly as Modeled.Please estimate a bid and sign the NDA for more information.

    Firstly, thanks to the freelancers who showed interest to our previous post for the same project. New freelancers are also welcomed to bid on this project.We delayed in replying to the freelancers because we were still updating the requirements. Now instead of 4 sensors (as in the previous post) we need 6 sensors to be part of this application. Please revisit the updated list of sensors below and provide estimation.Project Description: I am looking for a Android based smart phone application to control electronic sensors / home appliances.The connectivity between smart phone and sensor/hardware appliance is via Bluetooth.The project consists of parts - 1. Mobile User Interface (UI)2. Underlying Sensor Specific Code and Bluetooth Packet Generator3. Sensor DeviceAs a first step, I would like to develop/create the Sensor Specific Code and Bluetooth Packet Generator. For instance let us take that user wants to determine room temperature using a temperature sensor. From UI user requests for temperature. Command from UI is processed by corresponding sensor code (temperature sensor code in this instance) and is then converted into a bluetooth packet which is ready to be transmitted (done by "Underlying Sensor Specific Code and Bluetooth Packet Generator" module). The format of bluetooth packet needs to be defined, so that at receiving end Sensor Device can interpret users command. Sensor Device responds back with temperature determined by the temperature sensor, via bluetooth packet and then to the UI. Attached high level flow diagram for reference.The code must incorporate following updated six sensors:1. Temperature2. humidity3. Light4. UV5. pm2.56. PIRPlease Note: Each sensor specific code should be independent and should be extendable.

    Based on your profile, we have noticed that you have strong competency for Micro-controller and Bluetooth.We think you will be a great fit for our project, which involve a hardware and firmware design of a device that intended to be controlled by a mobile phone (android and iOS). The project will require a very secure approach for pairing method, proximity detection, and need for 2 way communication between the mobile phone and the hardware. No worry the app will be taken care of by another mobile developer which should make your life easier.Let us know if you are still available and willing to take on new project. If you so what would be the best time to have a quick chat.Details on the firmware/hardware will be discussed later in private messages.Hope hearing from you soon

(If the card is swiped half way and then back out and then forward in a fast,slow or jitter motion), the magnetic reader can still read the data from the card. It also must have a long life rechargeable li-ion battery. The device is required to be portable, so the PCB is required to be as small as possible. Thankyou.

    I have an app that I have mocked up in photoshop. I have pre-sliced all elements into individuals PNGs so you will have no problem making the layout.As far as the actual application goes, the functions will be self explanatory (based on the layout and controls). This app"s primary function is to control a Adafruit Neopixel strip of LEDs via Bluetooth based on different user choices of visual displays. There will also need to be a music visualization function, and a voice recognition (you can use any existing api for this) for simple spoken colors: yellow, red, etc.In order to aid you, we have obtained an open source application that has a very similar feature set and is currently able to interface with the Bluetooth LED strip.This job is urgent. As such, we need to weed out people that aren"t reading our description.

    I want the framework of an app built to evaluate a concept. The app should:1) Run as a service in the background always. Clicking the APP icon should open the app, but there doesnt need to be a functional GUI.The service should be able to launch itself if it somehow gets closed by the user (perhaps it can open on a slow timer, like once per day).2) The app should periodically (every 30 minutes), turn on bluetooth (if it is not already on), scan for discoverable bluetooth devices, and automatically pair/connect to our bluetooth device. The bluetooth device is one my company makes and controls the firmware on. We want multiple phones to connect with multiple devices seamlessly without having the user interact with the phone. If the app can"t find the bluetooth device, it should restore the bluetooth connection back to the previous, and go back to sleep until the next 30 minutes.We will place the device into discovery mode all the time. When the app comes close to the device, it should auto connect in the background.3) A bluetooth transaction should occur with details not covered by this work.The primary purpose of this project is to assess how seamlessly we can make this app work in the background. The idea is to use the phone to occasionally get some data from our device, silently and in the background, and process it. A successful outcome will be the user not having to interact with the app, the app consuming little to no battery power, and the app can generally be relied on to be running in the background.
