When vibecoders try to build robot arms
(turns out voltage adjustment knobs on benchtop power supply are physical knobs and change voltage when power is off)

ESP32, amp, mic, speaker, sd card, screen, two buttons and I’ve got a voice AI assistant and a meeting recorder + transcriber in one device.
Tried to make a mash-up of tiktok and Obsidian and it didn't go so well, most of the videos are just ads instead of quotes. The Obsidian part came out OK...
(might have to try a few videos to see a working one)

Today I'm releasing my entire newsletter archive (350+ posts) and all podcast transcripts (300+ episodes) as AI-friendly Markdown files. Plus an MCP server and GitHub repo.
A few months ago I shared my podcast transcripts on a whim, and y'all built the most amazing things—an RPG game, a parenting wisdom site, infographics, a Twitter bot, and 50+ other projects.
Let's see what happens when I give you even more data.
Grab the data here: LennysData.com.
Paid subscribers get all of the data (some 350 posts and 300 transcripts). Free subscribers get a subset.
I don’t think anyone’s ever done anything like this before, and I’m excited to give you this excuse to play with that AI tool you've been meaning to try.
Here’s my challenge to you: build something, and let me know about it. I’ll pick my favorite and give you a free 1-year subscription to the newsletter. Just post a link to your project in the comments here: lennysnewsletter.com/p/how-i….
If you’ve already built something, slurp in this new data and submit it, too. I’ll pick a winner on April 15th.
Check out today's newsletter post for inspiration on what you could to build: lennysnewsletter.com/p/how-i…
LFG.
Mass produced 157 free calculators with AI and deployed them to a single website. Nobody asked for this, but if you don't like giving up your email to see what a car loan is like..

If you have one of the larger Claude subscriptions, how do you use up unused credits at the end of the week?
What does it say about Powerpoint wizards that Claude for Powerpoint churns through tokens 10x faster than months of development work?

The unlock from this is we can score the coach output before and after any prompt changes and also model provider performance over time
Improvements Found:
- Repetitive phrasing
- Always supporting, never challenging
- Inconsistent length
- Loss of context between chats
If you're building an AI coach, would love to hear how you're evaluating it.
