I need someone help in developing a formula for a homework assignment I am doing with a patent leather shoe. The shoe is a red patent leather high heel shoe. The assignment is requirements are: Using a regular microfiber cloth, what formula is needed to change the red patent leather shoe to a pink with rubbing the cloth on the shoe (the heat from the rubbing of the shoe will induce the heat to trigger the color)? 2. Once you rub the cloth to the shoe and change the cloth, the shoe will have 72 hours to stay pink before it goes back to its original color (red). Is there another formula that needs to be implemented (think of a moon ring / technology) How will the shoe change back to its original color ***Remember, the shoe will not change color by the rain or sun, it will only change color by the microfiber cloth. The shoe must keep the gloss once it change color (must stay patent leather). Must know a formula ( or if its technology must know a way to make the color stay for 72 hours). The formula has to be accurate with an exact amount or weight. I have to take this to the lab to test it. Budget is negotiable

This item is a set of four stock crate rockers required for the removal of a stock crate from a flat bed truck / lorry. The contract owner has a diagram and photos of similar items for consideration and ease of understanding of what's required. The device will require some engineering consideration to ensure that the item built to their design is safe and within the requirements of the job at hand.

Hi there :) I need someone to assist me to look into the standards typically used with products using cryogenics. This will include going through company websites and seeing which standards (ISO, CE, UL) etc are listed. I would need companies in the following industries profiled: - cryotherapy (whole body and localised) - cryonics - cryogenic air conditioners and refrigerators - other I expect a applicant with an engineering background & with a solid level of English (however native level not necessary). Looking forward to seeing your applications!

We are needing to make a modification to our product. During testing of this product it was determined that we need to make the screw more secure. Currently there are two prongs (picture in the attached images) which are meant as a guide for the screw. However, these prongs are ineffective and the screw dangles loosely up and down and back and forth. This creates difficulty for shipping as the screws easily come out during shipping and also presents difficulties during installation as the technicians have to adjust the screw by hand each time. The screw is meant to be held in place ready for the technicians to screw it in without manual adjustment to improve speed. We need a guide that holds the screw securely in place with the tip of the screw right at the edge of the opening. The guide should not involve any extra parts. It should hold the screw tight enough to hold the screw in place during shipping but not too tight as to make screwing (with an impact drill) difficult. We do not require technical drawings. We just require a solution. Our engineers will work out the technical drawings.

I'm looking for help from an engineer who can help me create a prototype of a toy lego drone, similar to this one: The drone will have 2 foam missiles on them which can be launched for the remote control. It will also have a target on it, that when hit by a missile will trigger a light or sound to indicate a hit. - Easy to assemble by a child - Can be operated via bluetooth and smartphone app - Multiple drones can be operated in the same area without their signals clashing - Has to be as cheap as possible to produce - Has the ability to shoot 2 foam missiles from the drone (spring operated) - Has a target on the drone which when hit will set off a light and/or sound - Similar to this product: 2D drawing coming soon. Please get in touch if this project sounds interesting to you.

I’m looking for an experienced front end developer for a 3 – 6 month project. You will be working with the endless possibilities of ARDUINO. I would like to speak to you first to see if ARDUINO would work in developing my ventilation project. If you have another idea in getting this done, I’m open for suggestions. Here is ARDUINO: You will need to be able to implement Bluetooth technology and other modifications, I will explain more to the selected Engineering Developer. Please contact me after viewing this link and let me know what my costs would be to build something like this: If possible, I would like a mechanical CAD design created and to test how functionality would work.
