    PROJECT : Decoder for light flashes to drive an lcd sign. We already have an Android app to flash clock and data to the decoder.MILESTONES :(1) Identify 2 or 3 commodity mcu parts such as 8051 or PIC16. Identify 2 or 3 lcd driver chips, ½ or 1/3 for 7 segment or dot matrix characters Prepare B.O.M. Prepare schematic. (2) Make prototype board.(3) Write firmware.(4) Test.(5) Build 5 additional boards and install firmware.There is lots of code for decoders on the internet to cut and paste. See examples below.The lcd sign is a 32 character, 7segment character, ½ or 1/3 multiplexed with a Ton 90% of 4.0 Volts.Visible light flashing of CLOCK and DATA.

  • $722 USD 2 days ago

    I am working on a project to design a compressor/limiter microphone audio processor. I am a ham radio operator looking to build a box that will allow me to connect condenser microphones with 48 vdc as well as to control Push to Talk (PTT) with VOX (voice operated switch circuit. I can get very close with schematics that I have as I am a decent tech, but would like to have someone draw the schematics and PCB layout in Eagle so that I could fabricate. Basically its a 4 channel mixer with phantom DC power, Bluetooth audio/out, and compressor/limiter for broadcast quality microphone audio. I have a more extensive schematic and BOM available for discussion for the sinning bidder.I would like to set-up milestones for 1. Down Payment 2. Schematic draft complete 3. test board layout complete 4. Device test complete.I will have further revisions of the board that I will pay for subsequent feature additions but would like to have the ability to revise this circuit at least once to make sure that it is optimum for a first run.I envision this to be a 4-5 IC circuit with an XLR connector on the front, a LM3915 VU meter (I have in my circuit library), low noise quad op amps, for gain and VOX and a transistor high and low active switch. In addition the box will have a Bluetooth headset input with gain and VOX, and a USB soundcard interface. I"m considering using the SA570 compander IC also to provide the compressor/expander circuit. The purpose of this box is to allow me to use my broadcast condenser microphone or my BT headset with my ham radios.

    I am looking for a partner with knowledge in Artificial Intelligence, Matlab/Simulink and Electrical Engineering. The goal is to perform a research and write a paper about Artificial Intelligence applied to Solar Photovoltaic Systems. More specifically, you will implement an Neural Network technique for the tracking of the maximum power point in solar photovoltaic systems. Look for Maximum Power Point Tracking (MPPT) on Google. Advantages- $30- Your name in the article for an internationally recognized congress- You can put in your resumé/CV that you was part of a project linked with Carnegie Mellon University- KnowledgeThe paper is supposed to compare different MPPT techniques that I have already implemented on Simulink with a new technique based on ANN. I will provide you articles, my literature review and all the Simulink files I have. We will Skype (I actually prefer Hangout) and will explain you what to do. Even if you are not sure if you can make it or not, contact me, let"s talk on Skype and I can show you with more details.Please call me Fernando instead of Sr.Best,Fernando Wittmann

    Need to design an electronic circuit capable of transmitting inaudible sound in frequency range of 17 kHz to 19 kHz within a geographical area of radius of 70-80 meters. The sound signal would be carrying some predefined digital bit sequence (you can use any modulation technique as long as its mathematical demodulation is possible). Sound signal should be detectable by any normal smartphone available in market. Circuit should consume as much less power as possible. Heat dissipation, if any should be taken care.Let us know how would you do it & how much time would you need for this.
