Reactive Technologies

I have over 25 years experience working for start-ups, small companies, big companies, and as a freelancer. My specialty is rapid prototyping for proof of concepts, minimal viable products, and one-off designs. I can take your idea from conception to production, or anywhere in-between. My clients include commercial and industrial corporations, univ... ersity and pharmaceutical research laboratories, artists, and makers. Projects have been as simple as modifying Arduino libraries so that they play well together, to full custom product design with overseas sourcing and manufacturing. Some projects have even been to space. Check me out on LinkedIn: Visit Reactive Technologies on Facebook: Or browse my personal blog: RoboJay.us Projects are billed on an hourly basis plus expenses. I do not mark up parts and supplies purchased for your project, and will provide you with detailed hourly tracking and receipts. New clients will need to pay a deposit prior to work, and will be billed at negotiated milestones. Building things take time. I will provide you with realistic time estimates and make best efforts to stay on schedule. If issues come up, I will let you know as soon as possible, and we will work together to achieve success. I treat every client as a partner. You will only pay for services that you need, and I will deliver what you pay for. It's that simple. Live Long and Prosper. This is a WindSonde, a device carried aloft by a weather balloon that reports altitude and GPS location back to a base station. My client uses these prior to launching their rockets to check wind direction and speed at various altitudes. The design started on a breadboard to test the interfacing of the various off the shelf modules, let me develop firmware, and gain overall confidence. This design combined an Arduino Micro, Adafruit GPS module, XBee transceiver, SparkFun barometric sensor, Pololu motor driver, and a bit of custom circuits. I hand wired two perfboard designs, one for the client to test and one for myself. Perfboards are ...Read More
