An author since 1986, has written many technical service and engineering articles in magazines such as Popular Electronics, Modern Electronics, Electronic Servicing and Technology, and Radio Electronics / Electronics Now, Audio Electronics Magazine, Slot-Tech Magazine and Appliance Tech-Talk Magazine. Some published "assembly projects" are the Programmable Light Controller (EDS-63 Christmas Computer), Semiconductor Analyzer (SemiAnalyzer), Telephone Equipment Tester (TeleTester) ProCar anti-theft system, the Airconditioning Brownout Protector (A/C Sentry), the Microanalyzer, Semianalyzer and Bus Line Tracer.
As an electronics technician, Mr. Miga has extensive experience in the servicing of consumer, system control, audio, and communications electronics that dates from 1972. Experience varies from production and quality control of new products, to master troubleshooter for various service centers to repair units that others could not. Extensive knowledge in the service of digital microprocessor circuit designs, audio, radio and video circuits. FCC second class Radiotelephone license and ISCET certifications were both obtained without schooling, and only at the request of the companies of employ at the time. Of all 12 technicians in the employ of the service company that required them to take the ISCET test in 1983, Mr. Miga was the only one that passed.
As an engineering technician, although without a formal MSEE degree, Mr. Miga studied electronic engineering using university level books and professional training manuals. Experience is mostly in the professional contract designing, debugging and building of prototypes for manufacturers, service contractors, communications and medical electronics companies, and individuals. Specialties include extensive experience with 7400 TTL and 4000 series CMOS, embedded system microcontrollers, discrete and IC based audio and video, and RF circuits.
As a businessman, Mr. Miga started and ran three successful auto-electronics and communications retail sales and service stores from 1976 to 1982 (Florida Autosound Corp d/b/a The Delta Base). President and chief operating officer, in charge of purchasing, retail advertising, hiring, training, and firing of employees. Established a good knowledge of marketing, financing and bookkeeping. In 1983, assumed the position of planning manager with Lakes Electronics, changed the structure of retail-based customer service to better cash flow and improve customer-to-technician relationships. Also changed employee expense structure to take technicians from employee-based to independent agent system to reduce expenses. In charge of retail rates and schedules. Helped design larger location for company move in 1986. Retail sales for 1986 were over 300% of 1982 figures. Left Lakes Electronics in 1987. Started a consumer electronics service company in 1988 (Southgate Electronics). Sold Southgate in 1994. From 1994 to 2000, continued service as "Electronic Specialists", a consumer service company, from the original Boca Raton location. After the huge success of the EDS-88 CapAnalyzer, business was relocated to the large West Boca Raton estate. Mr. Miga retired A/V service in 2000, switching the service company 100% to computer sales, service and repair division. From 2000 to 2014, Mr. Miga ran all three EDS divisions from the west Boca Raton estate. In 2014 the manufacturing and computer service divisions were closed, devoting all resources to the engineering division. In 2018 Mr. Miga semi-retired and moved all operations to Keystone Odessa. Engineering and product development continues for current clients.
Marketing and Customer Relations:
Mr. Miga has extensive experience with retail advertising using FM radio stations, in magazines, with direct mail and writing for the EDS-inc website. Mr. Miga wrote all of the radio spots for "The Delta Base" and "Florida Auto Sound" stores, and wrote and published press releases for new product announcements. Mr. Miga designed all the magazine ads for the test equipment division. Products were shown in trade shows such as the yearly Appliance Tech-Talk appliance service convention, and electronic service trade shows such as the yearly NARDA/NASD convention for electronics technicians.
In dealing with customers, usually other engineers and technicians, Mr. Miga knows when to listen and when to help, and has helped numerous engineers solve problems and complete their designs in short time and on budget. In addition, he has written "how-to" troubleshooting articles, and many "kit construction articles" to investigate a need, and to develop a desire for a product to the kit builders, and this has led to a secondary marketplace for consumers who want commercially availiable units. Public relations and constant networking has also helped to form a well-rounded experience foundation in the entire product life cycle; from idea, to market research, to circuit design, to prototype, quality-control, public relations, marketing, servicing, trouble-shooting, and customer relations. Prototypes were made in the USA and most production is in China with final assembly and quality control in the USA. Mr. Miga has been interviewed for his opinions by several local newspapers and local TV stations, and has had his inventions featured on both local (WPLG, WPEC) and national network TV (CNBC).
