OVERVIEW I have a schematic diagram for a electronic stimulation system, meant for applying electric fields to different types of materials ranging from liquids to soils. The implementation is very simple, consisting of an 5V Arduino pro-mini module, with 3 different pin outputs going to a connector. Each output is different. One puts out 5V, another does 3V via a voltage divider, and the last one has a RC filter on one of the PWM ports. I also have 4 LEDs, 2 switches, a CdS light sensor and a power jack. I developed the schematic myself along with some help from some engineering mentors, but need help with validating portions of the design, namely the current buffer and ESD protection stages. I also need to make some minor changes to the board, e.g. Adding a push button. DESIGN When I prototyped the buffer output using a Npn current-follower, I couldn't see my source waveform showing up on my scope. Maybe I made a measuring mistake, but need validation from someone more ski...

This is an attempt to allow me to set the "fixed price" option, because in the other listing it only lets me hire you as "per hour" and "hours per week," and "number of weeks." The work is as before, converting solar panels into multiple 5V out charging USBs. Fixed rate is at (from previous message boards) Schematic and bill of materials - $1369.86 Circuit board layout, including gerbers and drill file - $547.95 This is totaled at 1917.81 I want to have one prototype up and running as soon as possible (ideally on or before June 8, 2015). I will pay you the 1917.81 as soon as the loan comes through, and will update you as more information becomes available. Thank you, Todd Campbell

I am a design student investigating air pollution related wearable technology and I am looking for an engineer who knows a lot about air purification systems, headphones and wearable devices (components) in general. A startup in China recently released their design for a wearable air purifier device and claims that it can effectively purify up to 3000 litres of contaminated air per hour. Here are some articles on the product:   [obscured]  /2014/11/headworm-headgear-china-air-purifier.html   [obscured]  /2014/10/30/chongqing-tech-team-rolls-out-worlds-first-wearable-air-purifier.php Essentially it is a "non-ozone electrostatic precipitator" with 6-8 hours of battery life and a very small pm2.5 dust sensor They have not released too much info on the product but a lot of people are skeptical of the device. I would like someone with enough knowledge in these related areas to comment on feasibility of the product, whether it can actually be effective or not. ...

I'm designing a product that requires a handheld controller which will regulate variable temperature to a wearable product. Think of a temperature controller on a heating pad. I will need this designed to my specs based on the heating element and application. There will need to be a small PCB with temperature safety cutoffs contained in a small handheld device. This a 110/120V A/C-powered system. I prefer a designer who can do both electrical design and has experience with plastic molding and/or can create a 3D printed case for the electronics. Electrical components will need to be able to pass any and all safety standards and certifications.

Looking for someone to assist me in finding a supplier or who can create a wearable wrist band that tracks (GPS, Temperature, and Heart Rate) where the info can be transmitted back via BlueTooth or Local Wifi Network we only need the hardware piece, we have all other aspects of the project covered. I have a feeling there is something already designed like this, so its just a matter of coming up with it. I will pay just for info about a project, or if necessary I will pay to have someone design this for us - needs be a cost effective sustainable solution

Without seeing the design I have in mind for this project it will be difficult to explain to you exactly what we want to produce. Essentially we're in need of a square panel (apx. 30"x30") made out of a .5 inch white cast acrylic that is translucent enough to trigger LED sensors through it. These sensors will need to be able to control volume, music controls (play, pause, next, etc.), an LED light strip, and a relay switch that powers two 110v 10watt lights. The panels audio components will need to include a bluetooth receiver for controlling and inputting mobile devices. It also needs an option of a 3.5mm stereo input that will bypass the bluetooth's audio for direct connection. This will all need to be output to a stereo jack (3.5mm or RCA). For lighting, the panel will need to include three functions for controlling a RGBW LED light strip. These need to include, set color, auto dimming, & sound activated responses. Also we need a relay sensor/switch to power on &am...

Hello, I am in need of some updates to be made to an existing Arduino-compatible PCB layout. The original layout uses all PTH components. These are being used for elementary education student courses, and I've found that it is too overwhelming for the students to have to populate the entire PTH PCB. So, I would like to have the layout modified so that some of the "less interesting" components (according to the students, which happen to be mostly the passives) are modified to SMT, leaving a few of the "more interesting" components (I/O, power, and MCU) as PTH for the students to populate themselves. The students will receive the boards with the SMT's pre-populated. For this job, I will provide the Eagle files (both schematic and layout), a revised BOM with the suggested SMT replacement components, and stenciling logo change. There are a total of 11 components that will need to be converted to SMT pads and the traces adjusted accordingly. The BOM is a draft, s...

I require a bespoke KVM device, with the following features: 1) In-line functionality - The device must sit between a computer and its KVM peripherals, so that a local user can make full use of the system, as well as a remote user. 2) Video support - The device should support D-SUB VGA, DVI-D and HDMI connectors. 3) Keyboard/Mouse support - USB support only required. 4) Storage - The remote user must be able to provide files to the computer. This should be implemented by uploading files to the device, which then presents a USB storage device to the computer. This should include the presentation of an ISO image as a USB CD/DVD drive. 5) Connectivity - The device should have at least an Ethernet connection, but ideally include a 3G/GPRS module for use in the event of wired network outage. The primary non-functional requirement is minimum cost per unit for production. I would need to see at least a high level design of the hardware and software before I could accept a proposal. Su...

Your task is to design a cup holder/Spice rack transporter (choose only one application). For the cup holder the intended use is to attach the cup holder system to a desk. There should be a part in cup holder system to secure a coffee mug in it. The intended use of the spice rack is to mount it on the wall or the ceiling close to cooking area. In both cases, the spice rack holder and the cup holder could be placed and locked above the working area. To achieve this objective, four parts/group of parts (subassembly) should be designed. They are: Attachment group, locking group, transport group, and cup/spice rack holder group. Each should address the following functional requirements. The function of the attachment group is to secure the transport group to a desk, wall, or ceiling. The function of the locking group is to lock the transport group so that it is not falling under its own weight. The function of the transport group is to move the cup holder/spice rack in the space anywhere a...

I have a large qty of wireless gaming controllers. The company no longer exists. They made 2 type, one that was a universal amd one that was not. I want to take the one that is not and convert it to be universal. It has bluetooth or sometype of wifi built in but i believe it is a fixed frequency that is out of typical range. It may be a hardware or a software solution. It does not matter as long as it works.
