I am looking to create a frisbee for a new game i have invented. The frisbee needs to be approx 175g including the electronic timing device. What i hope to achieve is a frisbee that when thrown is just a normal frisbee, but when caught it activates a variable timer 2/3/4/5 sec. The timer then activates LED's to flash if the frisby is not spinning before the time has lapsed. The electronics need to be moulded within the plastic with access to the battery and the switch for on/off and varying the timer needs to be accessible. Finally the unit needs to be waterproof, sand proof etc. As this will predominantly be a beach game.

Looking for someone who is good with logic and basic understanding of the game of poker. Poker has 10 levels from High Card to Royal Straight Flush. There is no real basic logical sense from one level to the next. I want to make sense of this game by making a kid version that relates to the gameplay of poker. A possible comparison could be Football (US Soccer) so a child can understand the rules and easily memorize the gameplay.

We are an Australian start up creating quality underwear and tshirts for men and women. We have a supplier for our T-shirts from Indonesia which allows us to do small qty orders. The problem is its hard to find anyone here that will do underwear. We need help finding a factory/supplier in china who will do small qty orders. We need the factory to create us a sample so we can check quality. This will be women and men's underwear that is mostly cotton. The elastic wasteband we have a supplier in China but happy to use the factory we team up with if quality can match. We have samples that we need copying with some minor altercations. Look forward to finding someone who can assist us with the process and into the future as things grows. Please put your per hour charge or an offer to us for total price so we can get an idea of what your are offering. Look forward to finding the right person to join this exiting opportunity.

I have an Autometer Speedometer that puts out a square wave at 5 volts DC. The faster the speed, the higher the hertz. I need a circuit that will trigger at 175 hertz and above and turn off below 175 hertz. It has to be powered by a 12 volt DC source. Would prefer if possible that the hertz setting can be made variable. I need it to put out a negitive trigger for a relay.

I have an audio source (portable cd player) connected to an amplifier through the AUX In. At the push of a button (preferably wireless) I need to have a device interrupt the current audio source by lowering its volume and instead feed a pre-recorded message to the AUX In to be played on the Receiver. The message is no longer than 30 seconds. This is similar to PA systems where when the announcers starts to talk the music is lowered. These are my constraint: 1. The solution has to be an existing device (or multiple devices) that integrates with my current setup. No computer solution. 2. I need to be able to easily record a new announcement on the device. 3. The cost should be less than $200.

We are looking for a partner who could help us to develop an IOT box which will contain up to 48 home keys. The box should be able to be opened via password provided though the app which we are building already. The Box will have a safe type pin code lock and the password will be provided via the app. Once the user input the passcode, then the door of the box and lock of the specific key will be opened. The box will be powered via ac adapter and wifi/lan cable should be available. The box size should be under 50cm high, 30cm wide and 10cm deep. The box material can be anything light weight but need to have strength that normal human can not penetrate with bare hand. The box must have water proof version and non water proof version. Below is a spec which we assume. Bluetooth Option Spec: - 5V Power supply for controller - 24V Power supply for lock device - Microcontroller module 400Mhz - Bluetooth 3.0 module - Relay switch - Electric door lock device - Developed firmware - 9-...

I have a Bluetooth Low-Energy beacon project that is based on a CSR1010. I have the beacon code working but the beacon function is currently broadcast (transmit) only. Now I need to add the ability to detect (receive) when another paired beacon comes into range. When another beacon comes into range it will trigger a PIO output. Need someone with lots of experience programming CSR BLE chips.

Hi there, I'd like someone to build a 12v circuit for me that provides a 60hz sinewave oscillator. We'll later take this sinewave oscillator and use some MOSFET transistors to amplify the signals. We'll then connect a transformer to create a 12v-to-120v inverter capable of 5000 watts. The power source of the inverter will be a 12VDC deep cycle battery rated at 110ah @ 20 hours. The battery will also be connected to an alternator providing 100 amps at 14.3 VDC. If you can build the oscillator, that's all we need for now - but if you think you can build the whole project, then great - please indicate that in your proposal. I look forward to your proposal! Please include the word "inverter" in your proposal so that I know you read this project description. Here's some reference material:   [obscured]  /watch?v=VDi_uFSr3w0   [obscured]  /wp/?p=415 I'd like the inverter to be as close to pure sinewave as possible, but that objective will be limit...

I need you to make me a circuit (tangible, not just diagram) that will connect between 2 of my solar batteries (12 V). When the first one dies, I need it to switch to the other (backup) battery automatically and keep them relayed / connected so that the solar panel will begin recharging the first one (that died). Please let me know any info you need and how much you will make me this circuit for. May need 2-3 of these circuits, so please quote me per circuit made. Thanks so much!!
