Micro-services Architecture with Oauth2 and JWT – Part 4 – Oauth2/Scopes

The last number of years I have been working in the area of migrating from legacy monolith (web) applications to a (micro) service oriented architecture (in my role of Java / DevOps / Infrastructure engineer). As this is too big of a subject to put in a single blog post, I will split this in 6 parts; (1) Overview, (2) Gateway, (3) Identity Provider, (4) Oauth2/Scopes, (5) Migrating from Legacy, (6) Oauth2 and Web. Introduction Recap: In the previous articles…

My daughter is quite artistic (as any proud parent would say), and created a wire animal in a bottle. For this bottle she wanted some lights at the bottom (inside), but… the requirement was that no wire may go through the glass (which would have made everything lots easier of course). By total coincidence, some weeks earlier I did order some wireless power transfer kits. They contain two coils and two little electronics regulator boards to send and receive wireless…

My last electronics project was creating a LED dimmer for some dinner table lights. This all works fine, but the bare light bulbs were a bit bright to look at directly. The MVP (Minimal Viable Product) version to fix this problem consisted of some ugly paper strips, taped to the bulbs 😉 Even though this MVP version did help, it doesn’t look too good, so a long-term-solution was needed. The lamp fittings are metal, and have some ribs which make…

I wanted to build my own WiFi dimmer, to connect my dinner table lights to Alexa (Amazon Echo Dot). The used parts are an ESP8266 (I used a Wemos D1 Mini Clone), an ATTiny45, some sort of power module to supply 3.3 volt, and a zero-cross-detector / Triac dimmer module.
