delabs has been online since the late 90s. delabs started adding its circuit designs on free website services like netscape and geocities.

Visitors started coming in larger numbers around 2000 and reached a peak around 2010.

The visitors were many DIY Enthusiasts, Amateur Radio People, Engineering Students, R&D Engineers and EE Firms. 

After 2010 the website popularity reduced due to some unhealthy developments in the world wide web.

delabs Sites

delabs electronic circuit designs are the main resource. These consist of Industrial and Instrumentation designs of delabs when it was a Manufacturer in the 80s and early 90. It also contains later designs to some extent which was related to the online design service.

Unfortunately plagiarism, imitation and content scraping has discouraged delabs from adding any more content online.

Many of my online ideas and designs have been used by individuals and companies without attribution or giving me the credit as the creator of that IP or Intellectual Property. Some took the credit for themselves and even obtained patents for Open Design Ideas of delabs.

Hence the Archive of designs, ideas and circuits will be maintained. Nothing new will be added after 2020 unless some serious contribution or support comes to delabs from the professionals or companies.

delabs Methods

A gist of Methodologies and Postulates from delabs Experience from the 80s as an R&D Engineer, Manufacturer and Businessman. Includes some worn out wisdom from my School and College Days.

delabs name was developed from a Garage Laboratory that i created at home. It was a Science Lab with Chemistry Apparatus that were used by my Grandfather and Electrical and Mechanical Gizmos made from abandoned parts and broken things. Visits to Flea markets for old Gramophone Records and Needles also helped me find Vintage Electronic Instruments and Industrial Parts for Enhanced Electronic Experiments. Much later came college and i became an Engineer and worked as an R&D Engineer. Then i created my own small Industrial Instruments Firm.
