Hello, I'm currently adding to a robot prototype I have, and would like to work with someone who has experience in working with manufactured products. Ideally you are a mechanical/electrical engineer or an industrial designer that would either help with the internal electronics and motors or a designer who will help with materials and 3D designs that are ready for manufacturing. The things I have already worked out are: - The way the robot navigates - Self balancing on ball (see picture) - Dimensions The things I need work on: - A way to interact with the robot - Developing the arms to fit the design - Work with parts (micro processor and such) to help when it comes to manufacturing

I am looking for a circuit designer (and possibly builder) who can use Broadlink Home Automation DNA to create an item that work through the Broadlink RM PRO to call lighting scenes. Broadlink is an existing semi-open source home automation system manufactured in China. The electronics seem quite high quality and they have created an aspect to their system called Broadlink DNA. This is a way that almost any other electrical appliance can communicate with the Broadlink hubs. Broadlink is a way of storing and centralizing remote commands for various light switches, TV and airconditioning systems. By using an APP on your mobile the system calls the stored commands and broadcasts them. What I am looking to do is create a unit that has a set of buttons that can be programmed through the APP to call scenes from the Broadlink. The scenes are a series of commands that activate a set of devices. This could be a "arrive home scene" where all the lights in a living area are switched ...

Hello, I am looking for ideas / approached / protocol suggestions on a wireless device implementation. Please do not bid on this if you do not have working experience with this type of network! I will not pay if you do not have real experience! My application has a master base / router to send out ON and OFF commands to the end devices.Each end device needs to be individually separately controllable. The end device is battery powered and controls a light. There is no real data to send upstream, so one way may be an option. The tricky part ... it needs to support 500,000 devices under the same roof. The protocols I have reviewed thus far will not support this many devices. So I am looking for protocol suggestions and frequency bands. Again DO NOT respond if you do not have real, successful, hands on experience! Thank you PS this device does not have to communicate on or over the internet. Additional information: The network topologies is open. I am able to use wired or wireless re...

Hello, I am looking for additional ideas / approached on a LiPo charger circuit. Requirements: Schematic - can be hand drawn if very legible Single cell LiPo battery (100mah, with no secondary protection) +5V input voltage And the final, most difficult requirement... Total BOM cost of <$ 0.20 USD in volume. This will eliminate the typical LiPo single chip charger solutions. Probably will require discrete components. Additional information: Charging source is a USB port so figure 5V 100ma Over voltage charging protection is required. Deep discharge protection is required. There is a micro already available, so a digital I/O and ADC is available for intelligent control. That can be used to enable a series pass transistor, and ADC to monitor voltage. You would need to provide all scaling / and interface circuitry. Low bat indicator is desirable, can use micro ADC if needed.

I am looking for a device that will wake a child up and remind them to go to the bathroom. I want this alarm to have a wireless shut off button that can operate on the other side of a house (50 feet). I would also like this device to be set, shut off, and monitored though a app on iPhone or Android. The main unit I would like it to be plugged in with a battery backup and the secondary unit to be battery powered.

Greetings, I'm a patent holding developer in search of a creative, active individual or group that can supply various control panels for several products I am currently prototyping. I can provide the necessary function of the device along with it's intended placement and user interaction but the development of the underlying electronics is beyond my expertise. So my ideal candidate is someone who messes around with this sort of stuff for fun and can take a concept and build AND SHIP me a finished product that I just connect and go and continue the development of the prototype. Thanks, Jeff

We have a project to build some prototype boxes with a mind to producing approx 10 per week later in the year I want someone to price and build the first box. I will work closely with you to deliver it. The box will hold an intel NUC, a 5 port switch module and aphantom power audio preamp. It must be able to all be powered from POE and provide POE to one of the network outputs. I have sourced the NUC and included details on the diagram I have sourced the POE splitter and injector Only the green items on the diagram remain open to source by you. The case should be plain and simple, standard off the shelf aluminium section is fine by me with custom end plate. but I am flexible and happy with suggestions included 3D printed. Please only send me details if you speak fluent english and send me your skypeID. I would like a price for delivery of the first box - if you need to ask me questions you can caveat your price with assumptions. I will assess the box with videos and photos etc...

I would like to create a circuit that controls 2 muscle stimulating electrode pairs with an arduino UNO micro-controller. Attached is the current circuit which works well for the stimulating electrodes, however there are a few changes I would like to implement to this configuration: - I would like to be able to adapt this circuit so I can control their on/off state using the arduino. This includes precise timing of when the electrode's become active and the duration for which they remain in the 'on' state. - I would like to be able to keep the integrated intensity control If this is a job you would like to take on, please do not hesitate to contact me and I will be happy to discuss details, any queries you may have and provide a full request for quotation. Kind regards, William Markiewicz

I need help putting together a control unit for a custom sous vide. I first looked at using a PID system but was told that a programmable touchscreen control could be the better way to go. I have a little electrical background but this is pass me. I need a unit to control the temp and time like a PID but I need preset buttons to hold set profiles. If this is something you could do please let me know. Thank you.

We have a series of circuit diagrams and an image of a PCB layout from which we need to produce manufacturing files and a BOM. We are aware that at least four components are obsolete, and suitable replacements must be found. This is a time-sensitive project. We have included the image of the board layout (two-sided), and an example of one of the four circuit diagrams with component values shown.

Hi, I'm looking for someone to design and build a small prototype board for a round, small (ideally 30mm diameter or smaller), coin cell powered device. The device would be placed on a horizontal lid and in "sleep mode". When the lid opens, the circuit is activated and a clock is started. After 5 minutes the device would beep once per 30 seconds. After 10 minutes the device would beep once per 5 seconds. Beeping would continue until the lid is returned to its original state (horizontal). Device would then enter "sleep" mode. I found this schematic online which I think would be helpful as a starting point   [obscured]  /5748/timer-with-alarm/. My thought is that an accelerometer would be used rather than a tilt switch for better reliability and smaller size. Buzzer should be relatively audible from one room to another in a typical residence. Once board is designed/built I would create a clamshell housing for it. Thank you for considering.(ID: 7...
