    Hi, My name is Cody Phipps and I am freelancer located in Austin, Tx. I am Electrical Engineer with a focus in power and control systems. While I attended Louisiana Tech University, I worked on many projects dealing with designing and printing PCBs. After started my career in transmission line studies, I quickly found out I wanted to develop electronics for my career. I started freelancing and evenutally started an LLC to chase my dreams as a product developer. Since then, I have developed over 80 products for many fields including medical, military/government and industrial. Products that I have develop include: - IoT and wirless capabilities (Wifi, BLE, Thread, LoRa, etc) - AC and DC power systems -Solar and alternate energy systems -Wearables -Many types of sensors - accelerators, temperature, humidity, etc In addtion to design, I also offer printed circuit board assembly and I have built a majority of my designs myself. I achieve this with my personal line that I have which is capable of building small run jobs (up to 500 units a week). I also have access to a larger line for much bigger manufacturing jobs. Here is the typical breakdown of what you would expect from my services: Research and Development: - Identify major components - Draw breadboard proof of concept block diagram - Build breadboard proof of concept - *See firmware Development Section Schematic Capture: - Draw symbols and footprints of components not in library already - Capture Power circuit - Capture MCU circuit - Capture peripheral circuits - Export Bill of materials Layout Design: - Determine board shape, constraints and layer count - Floor plan components - Draw power and ground planes - Trace Critical traces - Trace the rest of the nets - Run DRC - Draw Fabrication Drawing - Draw Assembly Drawing - Export Gerbers, Drills, OBD++, PnP, etc - Send Boards off to Fab - Order stencils, Components, etc Firmware Development: - Develop Firmware for POC - Add finishing touches to the firmware Build and Test: - Develop Test plan - Check in Parts - Assemble boards - Perform Testing - Write Product specification - Determine next steps I can give virtual tours of products I'm working on as well as give you five references to ones I developed products for and with.

    I’m Kevin. I design things. Over the last ten years I have taken over twenty commercial products from concept to manufacture while navigating startup challenges along the way. I am “practical” above all else. A team player and easy to communicate with, I am able to take rough concepts and deliver them as working products or prototypes with minimal cost and hassle. My specialty is electronic hardware design, though most projects involve physical or mechanical parts as well. This is my full time job, working from my dedicated workshop near Portland, Oregon. I have in-house capability for most aspects of bringing up new designs and fabricating one-off devices or prototypes. We have high resolution SLA 3D printing (UV resin), a large 4x8’ production CNC machine suitable for plastics and most aluminum, and plenty of bench/floor space for your project. I have relationships with various local machine shops and test labs, so extra support is convenient if needed. I work in Altium Designer for schematic and PCB board layout, and use Solidworks or Autodesk Fusion for physical component design and working with complex physical assemblies. I have designed many injection molded parts, stamped metal parts, etc. Many of my products involve radio so I’m familiar with the FCC test lab process for both module based radios and custom designs. I have designed Internet of Things IoT products, wireless mesh networking, and low cost proprietary point to point radios. I am intermediate level coding on small 8 to 32 bit microprocessors in C,C++. My code is extremely "human readable" and cleanly documented. I have solid experience with Mircochip PIC processors, Atmel, STM32, and MSP430. I have written several low level handlers for custom board hardware and protocols. If you’re looking for a competent person that is easy and reliable to work with, and who will handle your project as if it were their own, let’s chat and see what happens. Electronics: -Embedded Hardware Design -PCB Circuit Board Design -Low-level Microprocessor Coding, C, C++, Python -Radio Wireless Communications and Certification -Internet of Things, IoT, Mesh Networking, Zigbee -Robotics -Automation -Short Run PCB Assembly -Prototyping and Test Fixtures (in house) -Reverse Engineering, Proprietary Protocols -Testing, Debugging, Product Validation Mechanical: -Solidworks -Autodesk Inventor / Fusion360 -Complex Assembly Design -Process, Testing, and Assembly Fixtures -Injection Molding -High Resolution SLA 3D Printing (in house) -CNC Machining (in house) -Industrial Processing Fixtures -Plastics Fabrication (Tanks, Jigs, Wet Processing, etc.) -Rapid Prototypes and 3D Printing for Industrial Parts -Moving Parts, Gearing, Bearings, etc. Support Services: -Connections with Contract Manufacturers -Crowdfunding, I've raised approx $400k via Kickstarter, Indiegogo -Relationships with Asian and China Manufacturers -Injection Molding & Stamped Metal Parts from Asia -Patent Experience (I hold 7 Patents)

    I graduated from an accredited university with a bachelor's degree in electrical engineering with a GPA of 3.65. Since that point I now have over 10 years experience in various fields of engineering ranging from electric drives to security systems. My primary focus has been with embedded systems and PCB design. I have used numerous controllers in past designs however the most popular with my clients has been the arduino and various versions of it. Also the teensy has been a popular choice lately. I use Eagle Cad to design PCB's and can design up to four layers although two layers will suffice for most projects. I also have have experience with various IOT modules such as the laird bl652, esp8266, and the particle. If you have any questions please contact me.
