Little solar lights I think have just crossed an important threshold. In the worst of Newfoundland winters: overcast days, snow on their little tiny panels ~ they still charge enough to run through the night.
Melting out from under deep drifts, the batteries don't die - they spring back to life. Even after hundreds of charge cycles, still usable.
They are bright enough for illumination (not just decoration).

My hub75 based display has started having rendering issues lately. After messing around for a while and getting nowhere I believe I've finally fixed it by reducing the power supply voltage to 4.7V instead of 5V. I guess some of these displays don't really like 3.3V logic and reducing the difference helps.

Yesterday I managed to turn #esphome into a #wled knockoff. (Part of my #lamp system.) If anyone else is considering it, let me gently suggest No. It *technically works*, which is the worst kind of works.
Overlapping segments are great (really!) and way more reliable than switching presets, but that is where it stops. Mostly when wled Just Does, esphome+fastled Just Doesn't.
If you were hoping to piggyback additional capabilities, you should also know that 22 LEDs in pairs (plus "all") leaves about 9% free flash. This is not enough for audio, or most sensors. And of course control suffers.
That said, don't forget that every #ledstrip is also a #5v supply and there are no rules against putting multiple magic shards in a single object..

Since it'll take some time for the PCBs to arrive, I decided to make a #prototype on #perfboard. It works fine, and I can test my programs using it. Turns out an #ATtiny814 is good enough for the task.
The #WS2812B #SMD #LEDs are very bright, though, and reducing brightness also reduces the possible color range.
The different color shadings are not very distinguishable, yet. I might have to adjust the color palette.

ELECTRICAL POWER SUPPLY QUESTION
Can anyone here sanity-check the #electrical #power solution I've ended up planning for my next automated #insect monitoring tool?
This will be a unit running on mains power. It includes a #RaspberryPi 4B controller (also running a #camera and various sensors), along with a number of high-powered #LEDs (to attract insects and to illuminate photos).
The #RPi requires 5V supply and I am using an A009 BuckBlock to deliver constant current for the LEDs. This works optimally with a 24V supply.
The RPi will turn the lights on and off using a relay.
At present, I'm thinking that the best approach is to power the whole unit with a 24V AC-DC converter and then use a second 24V-5V converter to step down this DC for the RPi.
That means three power converters are required. In this diagram:
The cyan converter is for mains (ground is back through this converter, but the diagramming tool was not good for representing this).
The yellow converter steps down for the RPi power.
The pink converter delivers constant current for the lights.
Am I missing something? Can this be done better? Will I need additional capacitors to stabilise the RPi voltage when turning on the lights suddenly draws down an extra 27W, or should a decent step-down converter handle that?
TIA for any assistance.

@MakersHour Q1: who/what
A1: Hello, I'm Ted. This past weekend I did the a glue-up on a doll-scale version of an Art Deco column.
Also, as you see I'm on leds.social, there are LEDs involved, so I was testing the lights I plan to use. Because the diffusion of the acrylic panels isn't much, I'm trying wide COB strip.
Today or this weekend I plan to laser cut covers for the open parts on the top/bottom.

Alright folks unfortunately @darkosubotica re-tripped a desired hobby of mine and I'm going to get into programmable LEDs.
Looking for all suggestions and input! Its a tough space for hobbyists. I'll just be documenting my thought process here.
**What's important to me?**
- programming, not tinkering with wires and soldering
- I'm interested in individually addressable LEDs for fine-grained effects / fun. I know I won't use those capabilities to light my wardrobe, but it's fun!
- I like accurate whites. In a past life I was a theater lighting designer.**Things I have to figure out:**
- WLED supporting controller (ideally supports 5v and 12v)
- Zigbee vs wifi?
- Leaning zigbee, but then I need a zigbee hub, so which one
- LED Strip type (WS2812b vs WS2805), and seller
- Solder-less connectors?
- Surely something else I'm unaware of -

Skilhunt joins the bespoke LED club with the high-CRI SL-F50
This hasn't been officially announced on their site yet, but they sent me one and they didn't say not to talk about it, so here it is.
It's a 6V 5mm square quad-die emitter without a dome. It seems similar to the Noctigon NTG50 and Fireflies FFL5009R, but not identical as those LEDs have phosphor covering the space between dies.
Claimed color rendering index is 95+ with R9 (deep red) of 80+ and 5000K color temperature. Measured CRI is 95.8 with R9 of 86.2 and R12 (deep blue) of 83.6. CCT is 5020K with Duv of 0.0018 (very slight green tint).
In this small textured reflector, there's a bit of tint shift across the beam and a slightly dimmer area in the middle of the hotspot. I don't think either is problematic when illuminating anything but a white wall. Those issues wouldn't be present at all in a textured TIR optic.

New vid! #PCBs I made in 2025, part 1: LED charm ✨
https://www.instagram.com/reel/DTH1NuelDigFinally pulled together a prototype with this little board – one of my new #Charmware set, reviving the series of modular tech #jewelry bits I started back in 2018. Been dreaming of assembling these with elytra and bike-leather, and the day finally came... The board still needs some tweaks (smaller switch etc.), but with my fixed-up #KiCad workflow, those will be a snap. 😸

Planning on creating an #enclosure for my #diysynth #perfboard modules.
I'll use 5mm transparent #polystyrene for the body, and 2mm #aluminium for the front panel.
Here is a crude #prototype done in #cardboard.
I'll have to unsolder the #potentiometers and #LEDs to place them on the panel. The audio jacks will be connected to the pin headers.

My six year old #BeardGrabber is watching a video about the development of blue #LEDs by #ShujiNakamura. I wonder how much he understands; hopefully his younger brain will pick up and retain more than my tired one. 😅
