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...

Hi, We have an outdoor area that is connected to our business building. Since it is old and we want to put some work into this location and make it look nice. Attached is the floorplan and images of this room 41. So for this project, I will need your help to design this area. Color for wall, lighting, any other stuff that will make it look nice. I was thinking about putting our old treadmill out here for exercise. This area will only be use by 1 person so not a lot of traffic out here. With this project, once you are done with the design, I will need the following. 1. For the color(painting), I will need you to reference houzz for the color 2. Any furniture or objects, I will need links on where to buy them (us companies since we can have it ship locally in the us). Thanks!
