- Fleshed out the Linux Serial Ports Using C/C++ page with more info on custom baud rates.
October 2020 Updates
Resolved Netlify build error which started with commit 377ec8:
5:07:04 PM: ┌─────────────────────────────────────────────────────┐ 5:07:04 PM: │ Plugin "@netlify/plugin-deploy-core" internal error │ 5:07:04 PM: └─────────────────────────────────────────────────────┘ 5:07:04 PM: 5:07:04 PM: Error message 5:07:04 PM: Invalid response from buildbot: Error: The TCP connection with the buildbot timed out after 60000ms

You may have a circular loop in a shortcode, or your site may have resources that take longer to build than the `timeout` limit in your Hugo config file.
I then tried Netlify options to rebuild the
masterbranch without cache, and the build worked!
Added a page on the SOT-583 component package.
Added a page on the SOT-883 component package.
September 2020 Updates
- Added info about board packages to the Arduino page.
Added info about schematic page templates to the A Beginners Intro To KiCAD page.
Added support for the search service Algolia.
- Updated information about the
BCrange of BJTs on the Bipolar Junction Transistors (BJTs) page.
Added more online simulation tools to the Circuit Simulation page.
Added a new page on
555 Timer Circuits. Added a 555 timer calculator to NinjaCalc (which is also embedded on the 555 Timer Circuits page).
UPDATE 2021-05-22: The 555 timer info has been moved to the Timers And Multivibrators page.
Updated the Mbed Studio page.
Added a page on the EasyScale communication protocol.
Migrated NinjaCalc from a Vue.js based app to Next.js/React based app. This took quite a long time to migrate, I’m estimating about 32 hours to migrate all functionality except for two calculators to Next.js. Deployments are now automatically done by Vercel (I’m using the “Hobby” tier which is free forever). Unit/functional CICD testing has also been added with GitHub Actions. Commit https://github.com/gbmhunter/NinjaCalc/commit/458137fb79237562acb8a3f3d09a13d30438bb49 was the beginning of the migration.
Updated the Cables page with more information on cable insulation materials and combined power/data cables.
