    My job is to design functional and tested circuits and PCBs for your application or consult you, so you can do that your self. Just give me requirements for your circuit: the price for bill of materials, deadline and a list of required features. After prototype of device is designed I almost always advise I will order a few sample PCBs for testing. After testing and debugging is completed, I will ship them to you, so you can verify my testing results. This costs a bit extra for you, but you are buying 100% working circuit design which needs no testing. Just take it and use it in your project. If you want to know how a circuit works I can develop complete math model of the circuit. This approach is way more accurate than SPICE simulation and allows you to understand how the circuit operates. I have completed at least one project having fallowing sub circuits: Analog: Low noise, low speed front-ends (from Hz to 100KHz): Photodiode, strain gauge, pressure sensitive resistors, magnetic angle sensors, tensile, thermocouples and other. High order active filters Voltage measurement (uV to kV) Current measurement (pA to tens of A) Resistance measurements (mOhm to Mohm) Frequency measurement (below GHz) Current output Oscillators (Bubba, Pierce, Hartley, phase shift, relaxation, crystal, RC) Integrated RF transmitters/receivers Digital: PCIe USB HDMI I2S SPI High speed parallel interfaces Logic circuits (TTL, CMOS) SOCs Power: DC/DC converters: Buck, Boost, SEPIC, full bridge, Cuk, Linear AC/DC converters (up to 1.8kW) Brushless and brushed motor drivers TEC drivers CAD packages: DipTrace KiCad Altium I have fallowing equipment: 1x Osciloscope RTB2004 4 channel 10 bit 300MHz with logic analyzer having 16 differential channels up to 600Mbps. 1x Oscilloscope HMO1002 2 channel 8 bit 50MHz. 1x Multimeter HMC8012 5,75digit 1x Electronic load IT8616 1.8kVA 420VAC 20AC (60A peak) or 600VDC 20ADC with AC signal analysis 1x Electronic load IT8512C 120VDC 60ADC 1x Signal generator Rohde and Schwarz AFG 20MHz 1x TP3020 30V 20A linear power supply 1x HY5003-2 dual channel 50V 3A linear power supply 2x PeakTech 6080A 15V 3A power supply 1x VP-2000VA - 2kVA 230VAC to 120VAC converter. 1x DER-EE DE-5000 RLC meter I also have programmer for: Texas Instruments CC series, Texas Instruments MSP430 programmer, Microchip ICD3/PicKit2/AVR ISP USBasp, Segger ARM programmer, SiliconLabs 8051 core programmer

    Are you curious if I can help you? Read on. The definition of an Engineer: Utilizing science and technology to create things people desire. As an electronic system developer, I transform ideas into competitively successful products, specializing in embedded systems for consumer, tech, and medical industries. I have managed numerous products through their entire life cycle. I possess the education, skills, and experience required to take your electronic product idea from concept to production. We can begin by fleshing out the idea and uncovering any hidden issues. As the saying goes, "The devil is in the details." Once we have a specification, I can estimate the project's duration. A typical project includes designing a circuit, creating a board, programming a chip, designing a user interface, conducting multiple rounds of testing, and then preparing a document for handoff to production. During our video chat, I will gladly show you what all this entails. Good communication with all stakeholders is essential. Over the years, I have learned to adjust my communication style to meet the needs of the people involved. I have worked with both startups and some of the largest corporations in the country. My Master's of Science in Electrical Engineering and decades of experience mean I have pretty much seen it all. This reduces the likelihood of unpleasant surprises. While all this sounds good on paper, I encourage you to contact me with your requirements so we can discuss what it will take to turn your ideas into reality during a video chat. When can we get started? P.S. If you are wondering whether I can understand your project requirements, here is a partial list of projects I have worked on in the last three years: Designed a medical water electrolysis device, selecting all components, laying out the PCB, writing all the code in C, and designing the touch screen user interface. This design has been in production for over a year, and I have been invited to create an upgraded version. Redesigned a battery-operated IoT temperature and humidity sensor with an e-Ink display that reports readings to the Azure cloud. Several of these devices have been reporting readings for a large facility for over a year. Designed the user-facing electronics for an electric boat, including a touch screen and a Raspberry Pi. The backend dual CAN interface controlled the electric motor and battery. The code required to format the CAN bus data for the multi-screen user interface was quite involved. The user interface was written in QT. Used Swift and Metal to write a real time interleaving procedure for use with a special AR/VR interface. Wrote a special purpose voice input text editor using Swift. Designed a special environmental control chamber with its own lighting, sound, and temperature control. I selected all the components, including the innovative heat pump, and hacked the developer interface so it could be remotely controlled from a web-based app. I designed a temperature, humidity, light, and CO2 sensor board that reported readings to the Amazon cloud. I designed the PCB and programmed the ESP32 microcontroller. Designed a LoRaWAN device to report vibration and acceleration using pre-existing modules. I wrote the code in C for an NRF52. Designed an electric fence failure alarm, an innovative design that was efficiently self-powered. The alarm communicated with the cloud through a LoRaWAN interface. Advised a client on the design requirements for an electric varmint trap. This involved a detailed circuit analysis of a number of competing devices. Assisted a client in using a very inexpensive microcontroller for a residential lighting design. Advised a client on the design of a new kind of electric pile driver, a very high current and power application. Designed a circuit to read 250 low-level light sensors using an Arduino. I designed an analog board to amplify the light signal and manage the matrix of sensors. Advised a client on the technical challenges of a dog training device. Wrote code for a cleaning robot in C using an ESP32 microcontroller. Wrote articles about stun guns and tasers for a blog. Wrote articles for a new kind of supercapacitor for the company website. Tested the user interface of a Large Language Model LLM AI.
