Dear Joseph, We admire your experiences, skills, and services. We are a passionate small group of young people in California dedicated to building new, affordable technologies that improve people's lives. Since we are at an early stage in our startup with a stiff budget, our job is currently three-part in order to complete our 3D design and transition it for production and campaign it initially on a crowdfunding platform (Indiegogo or Kickstarter) that accepts our product to showcase to backers. The three job parts are as follows: 1) Two PCB additions 2) Digital product test (Autodesk or like) 3) BOM Our 3D design is for our vacuum-like microelectronics, which come in a pair. We anticipate a MCU in our PCBs that connects a custom-built microvacuum, 1202H004BH flat BLDC micromotor (or smaller), UVC microlight, photomicro sensor, Bluetooth, 1.55V 110mAh cell battery, and on/off button. Bluetooth is to allow them our two microelectronics to synchronously do the same thing. Our goa...

We have hundreds of industrial machines for manufacturing processes. Most of these machines have simple control panels and are not connected to the corporate network in any way. We would like to connect some of these machines to the corporate network and log the status of the machines to a central database. This way we can perform analysis on the machines. The first machine that we would like to attempt this for is a knitting machine. After opening the front panel of the machine, we see Molex styled connectors used to connect the front panel to the main logic boards of the machine. We have also found documentation that clearly describes the pin outs. We would like to tap into these connections and connect them to a Particle (  [obscured]  /prototype) Core or Photon. These prototyping boards are Arduino-like, but also come with a strong management platform. Much of the information that we want to capture is simple on/off status information. For example, is the door of the mac...

We need help designing a very simple circuit, that will fit our specifications. We are trying to use the attached LED, with the attached LED driver (or an equivalent), but we don't know how to design an appropriate circuit for our specs. We want the LED to run at 18.2V and 1.2Amps. We don't need anything fancy, no PWM functionality. We just need to turn the LED on and off very quickly via a +/- 5V signal. Please see the "Shopping List" below for further requirements and specs. SHOPPING LIST: Input Power 24v dc-27v dc Battery 150AH Led Requirements 1. Build a linear array of 120 light that will be powered using a 24vdc 150 amp battery. 2. The lights will be mounted on a heat sink that will cool the lights to temperatures well below the required operating temperatures. 3. Regulate input to each led to 18.3v dc and limit amperage to 1.2 amps 4. Ability to turn light on and off 10,000 times per second for 14 micro seconds. 5. Each LED will have a dedicated driver to prevent t...

You will get a real life netlist of a combinational block (no memory elements). Your task, is using standard Python programming language Generate a new logically equivalent netlist which only uses NAND2 and NOR2 gates, which replace all the different gates that are there already.(refer block32 notepad for verilog code) Requirements: ? Code should be tidy and commented ? The code should work also on other netlists ? make it as generic as possible ? The netlist generated should be a legal verilog netlist including input, output declarations, wires, unique gate names etc. ? Tip: use a text editor that supports highlighted verilog syntax like: sublime text, Notepad++, Nedit or emacs ? Assume the drive strength to be X1 in all NOR2 an d NAND2 that you would use ? Code should be easily extended to new types of gates upon request ? i.e. when a new netlist comes with new gate types inside ? the change process should be easy

ARDUINO-BASED CUTDOWN DEVICE FOR HIGH ALTITUDE BALLOON This project would involve designing, programming, and fabricating a finished prototype, possibly using a small single-purpose Arduino processor (i.e. Micro or Nano, or something similar) to serve as a cutdown device for a high altitude balloon. Requirements: - The device needs to be as small, lightweight, and durable as possible. - The device needs to operate using an Energizer Advanced Lithium 9-volt battery as its power source. Operation: Basically, the device would be a simple timer. - Turn on the device and a small red LED begins to flash, letting the user know that the device is active. - Turning on the device starts a 60-minute countdown. At the end of the 60-minute period, the device would activate a reed relay to allow current from the 9-volt battery to flow to a user-supplied piece of nichrome wire that would heat-up and sever a small piece of braided mason lin...
