hello Guys, i have a small electric circuit working with generator principle that needs to be improved. a PCB with coil on it passes by a magnet. the induced Voltage is then kept in Ecaps and is slowly released to drive 2 standard LEDs. please see attachment. the whole PCB is rather simple. only 9 components so far. in case there is small money needed for component etc, we will pay extra or ship from here...

I have a wireless flash trigger transmitter and a receiver. They work with a Amiccom A7105 chip. I want to develop something similar with an Atmel microcontroller and this Amiccom chip. I'm a electronic engineer and I need support for this project. I DO NOT need someone who writes all the code or design all the schematic, I NEED someone who can explain me some points : 1) I need to know how my trigger transmitter and receiver works(probably we need read the signals transmitted and received) (1-2 hours) 2) If they work with RF I need a quickly introduction on RF and protocol as ZigBee (1hours) 3) I need support to develop the library(SPI) to comunicate between microcontroller and A7105. (around 10 hours or less) I prefer working face to face so I prefer someone from UK / Italy or Europe.

Hello, I would like to create a new design for these camera glasses.   [obscured]  /product-detail/140degree-wide-angle-Ambarella-A5-camera_60289050481.html?spm=a2700.7724838.35.1.fGPqG8 The electronics will be the same, but the new look should be as close to this as possible.   [obscured]  /news/google-glass-price-release-date-specs-and-info The electronics and battery can be housed behind the ear, as in the original design. Once hired, I will have samples of original design to you to take apart. -Once design is approved, I want to have samples 3d printed, to test fit. Finally, I want to take product into production to be delivered to factory for electroncs.

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.

We are seeking an engineer with previous expertise in KiCAD. We need a PCB converted into a SolidWorks 2014 readable file format. There are several ways to create this: 1: We send you a BOM and a PDF of the board. You model directly in SolidWorks. 2: You already know KiCAD and Wings3D. 3: You have your own method. I don't really care about the method. I just want an accurate 3D representation of our PCBA so we can hand it to our mechanical engineer and insert it into our mechanical assembly. I hope to hear from you soon!

I have a 12-year-old Java program that I would like updated so that I can run it in an IDE such as NetBeans and make minor modifications. I'm not a Java programmer and don't wish to become one, but am familiar with Visual Basic. The program can be run online with   [obscured]  /~jgeabana/mol_dyn/KinThI.html, if you want to take a look. I have the Java source code but might be amenable to it being recreated in another language, if that would be easier. It's a simple program of about 800 lines.

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.

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 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.
