    Electronic Engineer - I Help You Bring Practical & Profitable Solutions To Market Iโ€™ll help you take your idea... to a schematic, to a PCB, then integrate software, take it to production, debug, document the process and get it out the door onto the market on time and under budget. Iโ€™m your go-to guy when you need technical skills to transform big ideas into tangible real-world practical and profitable solutions. โ€ข Need layouts and/or schematics verified? โ€ข Want enclosure design or retrofit electronics? โ€ข Seeking firmware design/development involving micro-controllers. Call Kevin. Who am I? I dig aerospace, rockets and airplanes. โ€ข Iโ€™m quick to absorb, understand and build on the information you give me. โ€ข When I see a problem, I step in to help solve it. And step away if Iโ€™m not required. โ€ข Iโ€™m trustworthy & honest, easy-going and love solving tough engineering problems. Who am I looking to work with? I want to help great start-ups bring great ideas to life and impact society positively. Honestly, I couldnโ€™t think of anything more satisfying than being part of a project that makes life better for hundreds, thousands or even millions of people and contributing to the world in a positive way through engineering. What I do is a real passion for me, not just a job. And because I understand that the most important investment you can ever make in your business (besides product development) is in the team you build. I would greatly welcome the opportunity to be part of your project. I started my career as a technician and worked my way up to engineer. I have a rare combination of skills, knowledge & experience, and I know what it takes to make your project successful. I am 100% dedicated to my craft and I love to win. Let me help you win. ________________________________________ Experience: I use Altium Designer for all schematic and PCB needs.

I specialize in developing products from concept to working systems. I can handle both hardware and software or work flexibly on specific areas like architecture and hardware design. Iโ€™ve developed two successful products: (1) KEYKatcher hardware keylogger โ€“ A device plugged into a PS/2 keyboard port to record and play keystrokes. It was popular among parents for monitoring children's computer use, with tens of thousands sold. Sales declined as PS/2 ports became obsolete (2) TightWatt pool timer โ€“ An intelligent controller for swimming pool motors, featuring a year-round algorithm. It was awarded a patent and gained national distribution. Through all the product development, Iโ€™ve created a system for planning and designing working products. This system reduces costs ( by reducing mistakes ). I frequently make product improvements in 1๏ธโƒฃ Lowering energy usage: important in battery-powered products 2๏ธโƒฃ Increasing performance: increasing sample rates or changing communications protocols 3๏ธโƒฃ Lowering product cost: making full use of the microcontroller peripherals to reduce external components I have completed more than 70 projects on Upwork but to check my capabilities or skills, you can check out the following projects: โžก๏ธ Hardware Prototype Design for Plant Monitor Product using ESP-32 โžก๏ธ Microchip ATtiny202 Code Development โžก๏ธ Energy Storage Monitoring System โžก๏ธ BM83 Bluetooth Application Schematic โžก๏ธ Embedded System with PIC Microcontroller & Accelerometer โžก๏ธ PCB Power Usage Optimization โžก๏ธ TI MSP430 Development Additional Skills: โž• Leading-edge technologies such as USB/USB-C, Lithium Battery Charging, LED and Color Mixing, I2S Digital Audio, and Analog Measurements โž• Common Communication Busses: USB, RS-232, RS-485, CAN, I2C, SPI, Infrared ( with carrier ) As mentioned above, I have a small home laboratory where I have all the tools I need to develop/debug prototype boards for your product. This includes: โš™๏ธ Multiple programmers for Microchip, Atmel, and TI parts โš™๏ธ Logic analyzers to quickly find issues with communication busses such as I2C, SPI, UART, I2S, โ€ฆ. โš™๏ธ A โ€œpower profilerโ€ with picoAmp range ( yes, picoAmp, a trillionth of an Ampere ) for power optimization of low-power products โš™๏ธ A reflow oven for assembling prototype PCBs โš™๏ธ Inspection equipment for verifying PCB assembly โš™๏ธ A fellow Upwork contractor is available to do the physical assembly work. She works at a much lower rate than me and has the patience to hand-populate / hand-solder prototype boards Some electronic inventory is on hand. I may have all the components in-house to complete your project Feel free to contact me through UpWork. Best Regards, Stephen
