Hello! I'm looking for someone to help to design an electrical circuit for an e-cigarette. Ideally, you have a knowledge in electrical engineering, you are vaping, and have experience with building custom box mod style batteries, etc. I would need someone to make a drawing of the circuit and a parts list that I would than order and solder together. More technical details on request.

General idea Preparing cattle for a livestock show typically involves the following: 1. Wash the animal 2. Place animal in chute/trim stall and blow dry 3. Once the animal is dry apply product to hair that encourages hair to fluff and continue blow drying the animal. 4. Clip the animals hair as needed 5. Style animals hair as needed; typically limited to legs Number 3 above is very important. Well trained and fluffy hair can be groomed to hide the animals faults. Lots of time is spent growing hair and then training it to fluff or "pop." My idea: utilize static electricity to fluff the hair. Once the animal is in the chute and dry, apply static electricity to "fluff" the hair. Once the hair pops, it could then be sprayed with product similar to hairspray to keep it in place. The system used to apply the static electricity would need to mount to the chute/trim stall and consider safety of animal and participating people; it could also be a hand held device. I am looking for someone to design this system Anticipated deliverables: a. Phase I i. Product development ii. Conceptual design b. Phase II i. Procurement and testing of assemblies ii. Mocking up the agreed upon configuration iii. Empirical test and evaluation iv. Manufacturing drawings

I want to build a PCB with the following features: IR transmitter/receiver ZigBee transmitter/receiver ( already built in cc3200mod ) Antenna to increase RF signal strength. Extra memory to store actions. RTC Temperature indicator Motion indicator Micro USB for power USB port to use dongle if no WiFi around. Ethernet port Reset button Power button for on/off LED Light indicator for power LED Light indicator for Internet connection Screen to show time, date, and room temperature (user can use this device as a clock) This PCB with IR transmitter/receiver will act as a universal remote and as a ZigBee transmitter/receiver. Both for Home Automation. My team has finished developing the iOS and Android apps. Backend has been developed on AWS. I have ready API’s and ready structure for the communication between the device and the backend.

I need a realization of a wireless video transmission to an IOS or android device from a custom pcb via wifi. The task includes: - software implementation of an app, which displays the transmitted video on the device - pcb which includes a wifi chip and a camera interface for hdmi video signals. - firmware for the mentioned pcb Range will only have to be around 20m. Its also ok if a PCB designer only designs the pcb and the firmware.

I'm looking for an engineer to help me with an experiment I'm conducting as a hobbyist. I need a simple radio device built, that can transmit at a certain frequency with minimal power output. The truncated scientific journal article, containing the specifications and desired outcome is copied below. More information can be supplied as well. Thanks: Frey, Allan H., Human Auditory system response to modulated electromagnetic energy. Journal of Applied Physiology. 17(4): 689-692. 1962. (*) Asterisks indicate unreadable characters in the original copy. NOTE: In 1962, frequencies were expressed as kiloCYCLES, megaCYCLES, etc., with abbreviations being kc, mc The intent of this paper is to bring a new phenomena to the attention of physiologists. Using extremely low average power densities of electromagnetic energy, the perception of sounds was induced in normal and deaf humans. The effect was induced several hundred feet from the antenna the instant the transmitter was turned on, and is a function of carrier frequency and modulation. Attempts were made to match the sounds induced by electromagnetic energy and acoustic energy. The closest match occurred when the acoustic amplifier was driven by the rf transmitter's modulator. Peak power density is a critical factor and, with acoustic noise of approximately 80 db, a peak power density of approximately 275 mw / rf is needed to induce the perception at carrier frequencies 125 mc and 1,310 mc. The average power density can be at rf as low as 400 _u_w/cm2. The evidence for the various positive sites of the electromagnetic energy sensor are discussed and locations peripheral to the cochlea are ruled out. TABLE 1.
