Creating User Interfaces Using LLMs: From Specification to Code
A seminar on how language models turn a written spec into a working interface: where they get it wrong, and how much the wording of the spec changes what comes out.

- HaparlamentorType a line from the Israeli sitcom הפרלמנט and jump to the episode and timestamp it came from. The transcripts were built by scraping and Whisper, not by hand.
- LoRa Gateway Log VisualizerDrop a gateway log in and get RSSI, SNR and frequency over time. Everything parses in the browser, which matters when the log is production traffic on a customer site.
- RF Instrument WrappersPython wrappers for Mini-Circuits power sensors, programmable attenuators, the Agilent E5061B and the DMX-J-SA motor. The layer everything else here is built on.
- Two-Pass AssemblerANSI C90 assembler: symbol table on the first pass, instruction parsing and base-4 machine code on the second.
How I work
- Test Console
Do it by hand first
I ran the RF test procedure instrument by instrument until I knew every step, then wrote a console that runs the sequence and records the results.
- Current Logger
Measure, don't assume
The logger captures transmit bursts and stores every sample, so a live test and a run from last month get looked at the same way.
- OPlanner
Use the data that already exists
The university publishes a calendar export, so OPlanner reads it for courses and deadlines instead of asking me to type in a semester.
