Is that dangerously close? Should I compromise on compactness to add 1 pin spacing(gives a bit more room for routing)? I do not want to.

Or should I just put isolation tape in between  

P.S: Ignore that unbeatiful soldering. I did it like year ago, with awful solder and they were my first solder ~victims~ jobs. Now, I do it leadless and shiny btw.

I am currently editing my video series about bristle bots. I am really happy to see how easy it is to tune them the way you want.

Readings from my DIY air quality monitor yesterday and today showing a spike in volatile compounds as soon as I leave the laundry to dry

This is with >95% organic cleaning products

I’m kinda worried by how much I inhaled before I started using organic products and when I was in a tiny space

IAQ (purple), temperature (red), humidity (blue) and atmospheric pressure (gray) are on the left scale; VOC (green) and eCO2 (yellow) are on the scale on the right

VOC, eCO2 and IAQ all represent the same readings from my sensor, which is a resistance when certain compounds are detected in the air

At 8:20 PM yesterday and at 3:45 PM today, I left my laundry to dry in the room below on the graphs; there was some leakage to the adjoining office room

For reference, this is how I built the project:

My DIY air quality monitor system has been out of commission for a while and I couldn’t be bothered to investigate it

But

I did this weekend, though, and I think I fixed a few issues too

The raspberry pi zero in charge of storing the readings was struggling, apparently kernel panic

So I reinstalled the flash entirely from a recent image, added my tools and my app, all of which took an hour

Everything is back and I iterated a few times on the microcontroller app, and it hasn’t been smooth but it’s been better than last year

Issues as far as I could see were:

  • too many WiFi thingies close together in a small room => RF interference
  • the bridge node was spending too much time not reaching storage over HTTP => not getting mesh sync => nodes disconnected

So I spaced them out and I added a timed reset

Let’s see how long this lasts!

I wish I knew how to get back to this state 😅

I have everything in git, so there is a history of the code changes but I never committed the list of dependencies and their version…

I documented all that after this point

I think I may have made my son an electronics hoarder. He said he didn't need one of his old toys and ose to strip it for parts this afternoon. All I heard from the other room was 'oh, this is a really nice button and DC motor' 😂
Now he's looking forward to repurposing them in a project

Bought another screen and I'm waiting for it to arrive. AAAANNNNDDD It won't fit either. Why do I keep buying these displays with PCBs on the back?! The display itself fits, but the PCB messes everything up.

Wellp. Another week of mourning having to buy another one. Although I'm having fun with this project, I really need to earn more money. :)

(Maybe I can separate the display from the board...? I'd need to buy a connector...but they are cheaper... Humm...)

Some more workshop work on the SDG2042X Linux GUI today (got a free Monday): Fixed 5 bugs in this round, including ARB handling on the real instrument, sweep fallback timing, preset handling, and one unsafe input-parsing corner.

I hope GUI is getting a bit less fragile / more reliable.

Project 0003: SDG2042X GUI v0.2.* — first patch round and bug tracker setup – togo-lab.io

Precision Clock Mk IV - mitxela.com

GPS synchronised, millisecond precision, automatic timezones and more!

New lab gear for upcoming TōGō-Lab projects: Picked up Nordic’s Power Profiler Kit II to get a good look at low-power behavior instead of guessing with a handheld power meter.

Setup in a virtual Win10 was easy. But getting it running on my Ubuntu workbench machine was a bit more fiddly than expected.

Nordic's AppImage works, but not quite as plug-and-play as I hoped.
