Welcome. My name is Philip H. Corcoran. I am a software engineer who programs microcontrollers, communications systems, databases, mathematical models, analytical reports and related interactive applications.
I have college degrees in computer science, mathematics, statistics and geo-information science (GIS), and I have practical knowledge of electronics. I have more than forty years of professional experience in developing automated data acquisition, analysis, reporting and control systems.
I work as a contract software engineer for a test equipment company in the Massachusetts North Shore area. A full-career version of my professional resume is available at career.corcoranscientific.us.
Corcoran Scientific
Corcoran Scientific is my part‑time hobby business for discovery projects focused on microcontroller‑based electronics. I design and program electronic devices using Arduino, Raspberry Pi and advanced programmable technologies. I offer free advice to help innovators develop practical project plans, and I provide professional programming and prototyping services.
Corcoran Scientific is a part-time hobby business:
► I cannot accommodate urgent requests. I work on Corcoran Scientific projects during my leisure time.
► I provide free assistance with discovery research and electronics design, since that is my hobby.
► I charge professional rates for software development, since that is my occupation.

Discovery Research
Discovery research is my name for the process of developing practical project plans. Innovators often come to me with general ideas about what they want, but with essential details yet to be worked out. Before the cost and expectations of a project can be estimated, the requirements have to be written out in reasonable detail. Essential features must be separated from convenience features, and practical technology solutions must be researched. Discovery research turns an innovative idea into a practical plan of actions. Discovery research is a hobby aspect of Corcoran Scientific: I help with discovery research for free and without obligation.
Services Information
- Corcoran Scientific is a part‑time hobby business conducted at leisure from Massachusetts through email. Corcoran Scientific does not provide on‑site services and cannot accommodate urgent requests.
- Corcoran Scientific designs and programs prototype microcontroller‑based electronic devices using commercially‑available technologies and operating at under 30VDC.
- The scope of free assistance for each project is at the discretion of Corcoran Scientific. Paid work is not considered until discovery research is complete.
- Reference designs from discovery research are for planning purposes only and are not intended as functional works. Reference designs provide a starting point for prototype development.
- Prototypes are field-usable, but only provide necessary features. Attractiveness and convenience are omitted. Prototypes are not "pretty."
- Each prototype generally costs from several hundred to several thousand dollars to produce, and often involves several months of work. Cost and schedule cannot be estimated until after discovery research is complete.
- Finishing work adds convenience features to the prototype work, such as attractive physical enclosures, appealing web pages, and easy-to-use mobile phone apps.
- Corcoran Scientific subcontracts most finishing work out to specialized professionals, after successful prototype testing. The cost of finishing work is driven by the convenience features desired.
- Devices that include motors or actuators, or that operate in special environments, may require custom mechanical design and fabrication which can add significantly to prototype and finishing costs.
- Features that require cloud services, such as telecommunications services, websites and mobile phone apps, may involve ongoing subscription and update costs.
- Commercial products are finished products that have been redesigned for manufacture, and which have been tested and certified for consumer or industrial use. Corcoran Scientific does not offer commercial product design.
- Confidential agreements (NDAs) are made with established clients only. Equity offers are not accepted. Corcoran Scientific does not accept projects for automated financial (investment, gambling or cryptocurrency) applications. Corcoran Scientific does not offer tutoring or academic assistance. Anonymous communications are ignored.
- All business of Corcoran Scientific is conducted under the laws of the Commonwealth of Massachusetts.
