This sourdough monitoring device has been a fun hobby project. Hardware took 15 minutes and software took 5 . Right now it's in a mini DIY box with ice packs for temperature control, and it rises nicely.

I learnt that after every feed, the fermentation peaks like an asymmetrical bell curve. Once it drops, that's the best feeding time, so it sends me a notification on my phone. A mature starter doubles consistently and levain triples. Thank goodness fermentation is this mathematical because I would not have figured it out by just looking at the mason jar.



On the software side, I am using buzz.xyz for the first time. In about 5 minutes, Bumble built a dashboard, monitoring logic and structured files that would've taken me a day or two in Claude directly. And API cost a fraction of Fable.

Right now I've just been collecting and analysing data before the next code run. I might include prediction analysis which needs ML and maybe add CO2 and pH sensors for accuracy but I reckon in version 2 or 3.

I am so tempted to build a temp-controlled box which would only cost $15 but time is a factor right now



I shared this ugly DIY circuit on a breadboard in the cardboard inside this styrofoam container to a friend who started her sourdough business from home and just opened a cafe in Singapore. She is so excited and wants to connect me with pasta madre and panettone experts. It's always a nice feeling when people like what you build.

But now I gotta figure out how to make it more user friendly and less ugly looking =)

The Core vs. Knots dispute from OP_RETURN policy change (Core v30's - 2025) to BIP-110's failed consensus proposal days ago consumed an enormous amount of community attention and goodwill over what started as a relay policy disagreement and escalated into a fight over who sets those rules.

Both sides saw themselves as defending Bitcoin's infrastructure, one against data bloat and node costs, the other against censorship and precedent-setting restrictions. These are important concerns and the people who spent a year on them weren't being petty or frivolous.

For the people watching from outside, they witnessed the robustness of Bitcoin's consensus in real time. BIP-110 needed 55% miner support to lock in early, but it only got 2.5%.

Despite it all, I can't help but think that the energy spent on this governance fight with a two-block splinter chain and heated debates came at the cost of attention that would have otherwise gone into building the financial ecosystems Bitcoin was designed to enable.

I doubt we have even tapped into 1% of Taproot's potential for building financial infrastructure that can empower people, enable global trade, and benefit billions worldwide. It's easy to get caught up fighting but we should never lose sight of what matters.

Keep building. We have so much work ahead of us.

After a failed sourdough starter attempt, building a kit to measure temperature + track its rise, with a bot to ping me when its time to feed (when it peaks). I’ve got ESP32 + ToF distance + temp/humidity + Telegram bot. Also testing buzz.xyz with goose harness + anthropic API to build the web dashboard. Buzz is fun. All in about $10 (hardware + api). My serendipitous kinda projects.

A starter is ready when it reliably doubles within a predictable window. But it goes through a phase. The first few days, bacteria rules and it stinks so bad. Then it has its moment of silence; you'll think it died. Finally the wild yeast wakes up and the smell shifts from sour to bready. Temperature, humidity, how much you feed all makes a diff.

Testing this, I was quite excited when it started pinging me but I was out all day and v1 fermented so hard it overflowed and coated the sensor. v2 sensor incoming with lessons learnt!

This girl needed some strength training alongside pilates and upgraded from pink dumbbells to pink kettlebells and whoa the burn. So good.
