What I learned building with Claude, and where you can learn too.
I'm Hisham, a cellular systems engineer who loves creating UIs with Claude. In my own time I build things with Claude and local AI models, and I write down what I learned, including what went wrong. Below are those lessons, and a few free things to learn from.
meFrom a chat window to a home hub
Part 2 of my personal AI engine. In one month it became the place where receipts, our calendar, the smart home and my Claude Code sessions meet, and its tools started to plug in.
Learn with me
- GenAI 101My free public course on generative AI, in English and Arabic, not Apple's.
- present-in-htmlMy free Claude Code plugin for making presentations in HTML, personal, not Apple's.
Want wireless and DSP? Free lessons in English and Arabic: Wireless 101
What I learned, entry by entry
Every entry is in English and Arabic.
From a chat window to a home hub
Lesson: a tool registered in ten places is a security bug waiting to happen. Keep one registry.
A shared calendar on the TV
Lesson: a cheap SD card can freeze a whole computer. Keep constant writes in memory.
Texting my own AI, end to end encrypted
Lesson: a message that was sent is not a message that was seen. Check on the phone, not in the logs.
Cloud vs. local LLM agents for lecture slides
Lesson: the skill's checker passed a deck that was still the template; a judge reading the slides caught it. A layout check is not a content check.
One HTML file, a whole Keynote
Lesson: HTML is more than websites. One file can carry its words, its look and its behavior, and open anywhere.
Two nails, two assistants
Lesson: the real takeaway had nothing to do with AI. When the tire light comes on, go look at your tires.
Bedtime stories for a three-month-old
Lesson: design from what a three-month-old can actually see, not from what looks lovely to adults.
Building Wireless 101
Lesson: AI writes clear lessons fast, but an engineer has to review every module for accuracy.
Generating voice from text using local models
Lesson: write for the ear, and check the words, not just the file. Local voices now draft a whole book for free.
Building a personal AI engine
Lesson: failures here announce themselves as successes, so fixes should make failure visible. Part 2 carries on the story.
Building an interactive Islamic kids website
Lessons: kids' content demands higher quality, and bilingual is hard but worth it.
Building WirelessHub with Claude
Lesson: a detailed CLAUDE.md file makes every new session with Claude productive from the first minute.
My journey, from Cairo to California
Where it started: wireless engineering, doctoral research, and the move into industry.
