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.

New #LEDs are here that are under 500 nanometers wide. These could power extremely high-resolution displays. spectrum.ieee.org/nanoled-rese...

I'm in the process of replacing all the landlord's 60Hz flickering prison guard white #LEDs in this house, with Philips Ultra Def. I don't want to waste, but the landlord brands all tend to fail in 12 months from normal use anyway.

@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.

If you want to support @LaserMistress and check out her various projects, like a light graffiti projector, various #zines , and her excellent primer on #leds , here’s her linktree to all that: https://linktr.ee/ClaireDanielleCassidy

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

Therabody JetBoots Pro Plus Review: 3-in-1 Recovery Tech

https://web.brid.gy/r/https://www.wired.com/review/review-therabody-jetboots-pro-plus/

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.

Here are the boards! I soldered a first one by hand, but the #WS2812B #LEDs are very close to each other. So some have burn marks. Hot air is no option, it would burn them up. So, I bought a hot plate and tried again. It's so much faster and easier! And it worked directly after #soldering.
I only need better solder paste, this one was difficult to clean.

And now a followup on how to actually update a row of LEDs efficiently, using bitplanes:

New vid! #PCBs I made in 2025, part 1: LED charm ✨

Finally 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. 😸

This is what happens, if you leave me alone with an #ESP32, a #WS2812 LED-Strip and some time.
I have not yet implemented it to display maintenance times. I believe #UptimeKuma will internally handle that as up and note the maintenance somewhere else, but I'm not fully sure.

#tinkering #homelab #diy #leds #idea

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.

A new XIAO add-on board from Seeed Studio next, designed for seamless COB LED lighting strips - I know some model-making friends who are going to love this one!

I quickly updated the code of a previous project, and I'm ready to start finding out what I can do with that display :)

But it's already been a long day, so it'll wait tomorrow :)

Considering options for volumetric LED cube. Am trying to straighten pebble lights in these tubes. There is a back channel signal wire currently superglued & I pulled this through with a thread. Thoughts on support to glue lights to & straighten? Grateful for technique & material ideas. #leds #neopixel #pixelblaze

Feststellungen. Abgeleitet aus meiner ganz persönlichen Erlebenswelt beim Navigieren durch den täglichen Verkehr.

Nummer 1: Den #autofahrende interessiert eine auf rot springende (Fußgänger)Ampel nicht. Es kam in den letzten 7 Tagen 0 mal vor, dass an den Ampeln, an denen ich als Radfahrer warten oder betteln musste, nicht zuletzt eine:r bei rot fuhr. #alter, #thissucks ! Was ist falsch mit denen?

Nummer 2: wenn ich (mit dem Auto) auf der Landstraße unterwegs bin: neue, rel. große Fahrzeuge blenden mich, immer! das ist echt nervig, dass die eine #Zulassung für diese hellen #leds bekommen

Bin ich da allein? das kann ich doch nicht hinnehmen? Für #1 werd ich die örtlichen Verkehrsüberwacher informieren, aber für 2 brauch ich eine: #Anwältin #autokorrektur

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.

Learn here how to install the wLED binary, which means flashing your ESP32 microcontroller.

Make sure your power source is constant, which means use a uninterruptible power supply, UPS, at least while you are flashing!

Please do not brick your ESP32

This is een important word of warning from the wLED Creator

New setups should use the ESP32 not the dated ESP8266 because that micro controller reaches end of life / end of support soon. The ESP32 also has Bluetooth which The ESP8266 lacks.

Heed his Warning
