I need IC diagram that should be the backbone of a Handsfree. It should include the following modules: - Power supply module. Rechargeable batteries. They should be small enough to fit in the handsfree. I've found this model (MS621FE,   [obscured]  /attachments/solar-study/seiko.pdf) but I'm open to suggestions for others. - It should be using micro usb as source. - Red LED indication when the usb is plugged and the batteries are charging. - Green LED to indicate when the usb is still connected but the batteries are charged. The LEDs should not be lighten at the same time and should be small so they can fit in the handsfree. No LED should be on when the usb is unplugged. - Overcharge protection - This part should be designed in such a way that no harm is done to the batteries while charging and discharging. And there is absolutely no risk to the users. - Bluetooth receiver module. Other devices should be able to link to it via bluetooth. I am aiming to transfer ...

Hello, I am looking to hire a writer to create 5 detailed plots, for a series of steamy Billionaire Romance novelettes. If you have a fertile imagination and love making up stories, then this is for you. The books will revolve around the same family.Plots are to be well laid out, with character descriptions, main scene descriptions and plot outlines. The plots are for 15,000 - 20,000 words stories so should be around 1500 words each. Each story plot should have a surprising twist but needs to end with a Happy Ever After for the 2 main characters. The plot stories should also end in a cliffhanger/tease with the main character in the next book. Plots need to include juicy, dangerous, steamy, titillating encounters, wrapped around an interesting story/mystery/secret/quest etc, so your standard billionaire spank story, with zero substance will not do. Project Budget is $100. Person Requirement: - Excellent command of the English language at a Native level. - Experienced with Contemp...

Hi, I am looking for someone to build us a prototype laser microphone. This is a tool for surveillance to listen to people behind glass, we want to make a really long range one which would work at more than 500m, the more distance the better. Here is some inspiration:   [obscured]  /5961503/build-a-laser-microphone-to-eavesdrop-on-conversations-across-the-street   [obscured]  -laser.com/html/laser_voice_transmitter.html   [obscured]  /hack/how-to-long-range-laser-microphone-spying/ I want the system to use a non-visible laser, and to be small, with good battery life, at least 6 hours. I want to include digital noise reduction and the ability to record. This project is to create a working prototype, so you should be experienced in audio electronics, we will supply you any parts you want - you just need to build us a good products and provide instruction on how to build. If it works out well, we would like to offer you a further contract to manage the final production ...

ARDUINO-BASED CUTDOWN DEVICE FOR HIGH ALTITUDE BALLOON This project would involve designing, programming, and fabricating a finished prototype, possibly using 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. Requirements: - The device needs to be as small, lightweight, and durable as possible. - The device needs to operate using an Energizer Advanced Lithium 9-volt battery as its power source. Operation: Basically, the device would be a simple timer. - Turn on the device and a small red LED begins to flash, letting the user know that the device is active. - Turning on the device starts a 60-minute countdown. At the end of the 60-minute period, the device would activate a reed relay to allow current from the 9-volt battery to flow to a user-supplied piece of nichrome wire that would heat-up and sever a small piece of braided mason lin...
