I need a circuit drawn. The end result will operate like a solar powered lawn light. It will be scaled up. I already have some solar cells and hopefully they will work. Each unit can hold up to 8 solar cells. They are 3" x 6" - 1.8W each. The cells can be used to turn the circuit on at night by using the circuitry. I have a battery but unsure whether it will work. Super rechargeable Li-ion battery - model DC12400 input 12.6VDC output 12.6-10.8VDC 4000mAh (these batteries came from China and are difficult to get a hold of. If we can source a suitable replacement in the US that would be preferable) The battery would need a charge controller built on the board as well. all this is to power some LED strip lights. I purchased some that may be a little too expensive for the application. They are SUPERNIGHT 5M Waterproof 5050 SMD 300 Epoxy LED strip light white. It is 16' long but can be clipped to smaller sections. I know how to solder so that's not an issue. These are waterproof ...

We are looking for consultant that can help us do some fairly basic electronic design work. We have budget for this project and are ready to start immediately. Essentially we want to take an existing reference design for WiFi enabled smart plug (   [obscured]  /tool/TIDC-SMARTPLUG-WIFI ) and perform the following modifications: 1) We would like to have two (2) completely independently controlled and monitored egress power ports. Per the documentation, the relay, meterology and microcontroller per egress port is "scalable" so this looks to be a fairly simple task. We would ask for help both with the hardware design as well as the software modifications to be able to control/monitor the second port similar to the primary (note: I am linux software engineer with 20 years of experience, but I have never written hardware drivers). 2) We need to add an electronic or mechanical switch: the board will be housed in a lockable chassis, I just need some notification when the ch...

1. Review schematic for mistake. Component pin out, labels, wiring connections for a part. 2. Review all part footprint and fix. Component CN2, U2, L1, CN3, U7, IR1 and IR2 need footprint made or adjusted for sure. Check ALL others to DigiKey part numbers and confirm. 3. PCB outline is created. It is 43MM round. It is 4 layers. Some components have required placement. After you confirm above, send files back. I will place a few components and lock. These can not move. After you place remaining components. 4. All test points (TP) need to be round pad 40x40mil and placed all on one side of PCB. These are used to load firmware during manufacturing. 5. Send PCB to me after placement. I will verify before route. 6. Route. Follow standard PCB rules. Minimum trace width is 10mm. Can be 8mm but only if need. Power traces should be bigger. GND and Power pours where needed. 9. After route send to me. I will verify. If satisfied project will close. If not, additional route cleanup will be...

This posting is for the delivery of a schematic and PCB design and layout of a 40W, 110V, 60Hz sine wave inverter. This includes design documentation and all files (GERBER, etc) required to manufacture and modify the design in the future. The incoming power will be from four of the attached lithium-ion batteries, arranged in a 4S configuration, which are already regulated to a 4.1V maximum charge by another circuit. Therefore, maximum input for the inverter circuit will be 16.4Vdc. Circuit size should be no more than 3x2x1" (LxWxH), and the smaller the better in all cases. Height is of highest concern, but overall size should be as compact as possible. The inverter will be in an IP56 minimum container, so heat generation is an issue to be mindful of - heatsinking to the outside is possible, but a design that generates little-to-no heat is ideal, and should be possible with this low of wattage. Audible noise should be non-existent - transformer selection should be of high quali...

I am looking to get an anemometer designed. The output needs to be read into a low power processor. The processor has voltage comparator pins and also ADC. Not looking for the processor design - that is already part of current design. Need to add the anemometer . The anemometer needs to be super low power design that needs to work off of 3V (2 AAA batteries) and needs to be turned on and off from the processor IO pin. Physically the anemometer needs to be small in size - 2"x2" max lengthxwidth and as thin as possible.

This project would involve programming a small single-purpose Arduino processor (i.e. Micro or Nano, or something similar) to serve as a cutdown device for a high altitude balloon. The way it would work is this: the Arduino would use a timing chip, or a GPS receiver chip, or a barometric pressure sensor as a triggering device. Once the balloon is launched, the Arduino would, at a specified point during the flight based upon elapsed time, altitude, or barometric pressure, open a relay to allow current from a 4 x AA battery pack to flow to a piece of nichrome wire, that would then heat-up and burn through a piece of string. After 5 or 10 seconds, the Arduino would close the relay circuit and the flow of electricity would stop. That's it. I'm looking for the Arduino to do this at an altitude of about 60,000 feet, or after an elapsed time of 60 minutes or at a barometric pressure of 2.0. I'm not looking for a single device that would incorporate all of these capabilities. I'm looking fo...

Hello, I need a report and/or spreadsheet that outlines the majority of fitness bands on the market. What I need to know are: Manufacturer Model Blue Tooth 4.0 ((BLE) ? Acceleromter/brand/device Gyroscope/brand/device Magnetometer/brand/device Android Compatibility iPhone Compatibility Software API that allows access to streaming of raw sensor data? If yes, what is the max sensor streaming rate? (>50Hz required) Average Price Many bands such as Fit Bit, Jawbone, Adidas X_Cell, etc provide higher level software API's with no access to low level sensor streaming data. The Android Watches, Microsoft Band and Pebble watch do indeed provide for this. Please help me find low cost fit bands that provide access to low level sensor data as well as the additional information outlined above.

Hi, this project is about developing 3 micro circuits (1 of them is remote controller). I need developer to make the following microcircuit: 1) Micro circuit with LED lights strip (6 LEDs) remotely turned on and freezing for 8 seconds, and then self shutting down. size: 80x30x8mm max Working Voltage - 12V max 2) Micro circuit with LED lights strip (6 LEDs) remotely turned on and freezing for 8 seconds, and then self shutting down, size: 80x30x8mm max Working Voltage - 12V max 3) Micro remote control (not IR), it is desirable to radio waves (or Bluetooth). Which will operate at a distance of 10 meters (max). The purpose of the remote control is to switch on LED lights described above. So remote control will have only 2 buttons (each button turns on each device with LED strip). size: 45x25x10mm. Working voltage - 3V max. Briefly, I need 2 separate devices, which controled by remote control (3rd device). Budget: TBD

Hi, I would like to hire someone to build a circuit board with electric shocking element. Please only countries that can safely ship this without risk of it being seized by customs! In the attached pictures, you will see what the final product should look like. The schematic shows the device I currently have. What you create will be identical except that it will probably not have a voltage regulator and it must also have a potentiometer. The shocking element will be at the end of wires attached to the PCB. There should be a potentiometer added to the circuit adjustable so that the shock is mildly painful at the highest setting and almost unnoticeable at the lowest. In the middle it should tingle just enough to wake someone up if they were sleeping. I do not know what voltage are necessary to do this, so you would have to experiment on yourself. The board should fit inside 2.3" x 3.7" and accommodate a 9V battery. If this is possible and you can do it, please message me...
