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.

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...

I am looking for someone who will assist me in the design of a cosmetic compact which will primarily be made out of wood. The product will be aimed at the high end market and will be required to have a faultless design and finish that will appeal to people willing to pay a premium. The product will hold replaceable make up 'pans' and I will need assistance in the design of the fixing mechanism in which the pans are placed and replaced in the compact. Ideally I would be best supported by someone who has experience working on high end and/or luxury items with multiple components and who are able to fully design for manufacture. I am looking for someone whom I can give a detailed brief to and they will be able to come up with innovative ideas for the design and replacement fixing mechanisms. I will also require assistance in the design of the primary packaging and make up brushes, however this can be arranged separately. attached is an example of the size compact product we would be lo...

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 am looking for someone who has deep experience in plastic molding, extruding, design and fabrication. I need to develop a product that is able to slide over a piece of rectangular steel tubing (with fairly tight tolerance) to protect it from drop impact and abrasion. The steel is 6"x3"x1/4" wall thickness with radiused corners. An example of the steel is here:   [obscured]  /products/hrsteel2.phtml?page=rttube The plastic needs to be fade resistant (completely non-fading is preferred if such a thing exists as this product will be outdoor). This material should also be resistant to coastal salt spray and typical road chemicals. It also should be CNC machinable, resistant to impact/abrasion and is ideally available in many colors (the ability to custom match would be perfect). I prefer lengths provided up to 20' long which we could then cut to length and machine in our shop. My guess is that these will need to be 1/8"-1/4" in thickness. The...

To create a 3D model of a kettlebell as per images and output in either SLDPRT or IGS or STEP file format. The zip file attached shows a version created in .MAX. Unfortunately this file format is not usable by the factory that is to manufacture the prodcut. We therefore need the file recreated in one of the above mentioned formats. Since the 3D model was created, the Kettlebell shape has altered slightly. This can be seen in file named 'Updated Kettlebell Shape.pdf' where the top curves (from a profile view) are smoother / the 'bell' is less rounded nearer to the handle.' This is an urgent job so we would require it to be completed by the end of the week.

Must sign a NDA, An electrical or non-electrical, strictly mechanical way to sharpen a pair of scissors. Accuracy is the main design factor. Needs to have a way to lubricate the metal if it is designed like a honing machine. Needs to be easy to use for anyone, as well as safe. Looking for someone that we can work with from the beginning of a design, testing and a final prototype in hand. Looking for just some rough design ideas and a couple drawings. Might lead to more work all the way to prototyping.
