I want to make a mindfulness bracelet. The bracelet will vibrate every hour or 1.5 hours to remind the wearer to focus their mind and thoughts on what they're doing right now and to be present in this moment. I do not want it to be bluetooth compatible. I'd like it to have an on-board accelerometer to turn the device on and off automatically (if this is going to be expensive and bulky, I'm okay to have an on and off switch). I'd like to have a button or switch on the device so the user can chose 60, 90, or 120 minutes. That's it. A simple bracelet that vibrates every hour or so, can be turned on and off, and the time interval can be changed. I need the hardware designed/created to be able to move on to the next step.

I do not see any call for an Arduino. A micropower PIC chip should work. I see where the accelerometer might be desirable, but for me, personally, if I am drifting in random thoughts I am not moving. others I know become hyperactive when distracted. Can you explain your thoughts on that? Needs a battery, a charging method, a piezo buzzer, the buttons, and the sensor. Maybe also a thermal sensor on the inside surface so if it is not being worn, it does not operate. Display? Waterproof? Impact resistance? How will it recharge?

Hi, Many years in the business of electronics design and development. Capable of taking a idea from concept to manufacturing. I have the resources available to assemble and test prototypes with full reflow facilities. There is nothing out of the question with the specifications you have supplied however much (as always) is in the detail. Typically of this class of devices is managing the amount of energy required and how to store it. i.e. Managing the bulk of the energy source compared to the energy demands required. There are a number of ways that device activation can be done other then using an accelerometer but the costs of using one are no longer prohibitive. How far did you want to take the development at this stage? You referenced two kickstart projects.. is this a new one? Always happy to chat. James Harrison-Smith (Sydney).

Hello, how are you? I hope you have a bright day/evening from your side. I have read the details provided, but please contact me so that we can discuss more on the project. I believe I have the required skills in this case. I will work on your requirements personally since I do not outsource to third parties, this guarantees you high-quality work that is delivered on time. You can also request for revisions till you’re fully satisfied with the work. I believe writing is a passion and not a money making business where people will deliver low-quality work just to get paid. Try my services, and you will never regret. Waiting for your kind response

Can create a simple timing circuit and look into accelerometer options although I believe a switch would be better as wearing it would cause multiple false positives on the accelerometer throughout the day if its used to turn internal services on and off. I assume this is for electrical design only and you have a mechanical designer as well. I can keep consideration for spacial battery power concerns and the smallest circuit possible. Also assuming this bid is for the design files only and maybe a breadboard prototype. An actual circuit board made from this would certainly be more money to be fabricated.

Hi! I am an engineer from Ukraine with over 5 years experience in electronics design and electrical engineering and near two years in web development. During 5 years of working for Efes-Electronics LLC I have been participating in and studying full cycle of electronic components and parts production, took active part in the design and installation of hardware and software process automation and control systems based on industrial PLC's. I was developing my own hardware platforms for the needs of Ukrainian industrial enterprises like Zaporizhstal, Azovstal etc. I also participated in the development of auxiliary electronics for Daewoo passenger cars. You can find examples of my works in my portfolio. Feel free to contact me for any additional information about my experience. I'm interested to work on promising turn-key projects combining both hardware and software development for end-customer market or for commercial and industrial applications. Kind regards, Eduard.

Hello! I can do such thing. Development, manufacturing, shipping included. Microchip, power supply and accelerometer. Programmable. I think, the better variant will be without the batteries (like watches driven from hand moving) and without buttons: just connect to computer/phone and reprogram. Regards, Mikhailo Kudin

A quick search has shown me that an accelerometer can be easily be implemented. We will have to collaborate the design, a quick brainstorm makes me think that a device aesthetically similar to a fit-bit would be suitable for this device.

I will make circuit that consists of accelerometer and sense electronics that does on/off functionality. I will implement a circuit consists of buttons that can be pressed to set the vibration timing duration to 60, 90 or 120mins. NOTE: This will be large in size (circuit board), like a functionality prototype.
