New satellite images show the scale of demolition that has occurred on the East Wing of the White House in less than a month.

Two of the pins are intended to connect to NCTs (as temperature sensors). However, the elements are not actually present. So either it was determined during the design process that temperature sensing is not necessary or the LED board is used for multiple different products.

JK @jk8051.bsky.social · Sep 13

In terms of the overall design philosophy, it's interesting that this board has absolutely no logic at all. Just the LEDs and a single zero-Ohm resistor. The RGB pins are just straight-up connected to the corresponding LEDs.

Removing the second, internal diffuser reveals the colour LEDs and the other side of the 8-pin connector. Notably, the board does not use multi-coloured LEDs. Instead, there are 12 monochrome LEDs (4 R, 4 G, 4B), presumably in an effort to keep the cost as low as possible.

Picture of the LED board with the frosted internal diffuser removed. Under the diffuser, we see the other side of the 8-pin connector, as well as 12 further LEDs. Instead of multi-colour LEDs, there are four red, four green, and four blue monochrome LEDs.

The rear of the board is covered in aluminium (and thermal paste) to better conduct heat away from the LEDs.
Note the 8-pin connector at the top. This links the LED board to the rest of the lamp electronics.

Same as the previous picture, except that the rear of the board is still covered in a thin coating of white thermal paste.

With the outer diffuser removed, we can see the board carrying the LEDs. The outer ring of LEDs is warm white. The frosted dome in the center covers the RGB LEDs.

Top-down view of the lamp with the external diffuser removed. There is a ring of 12 warm white LEDs on a PCB with white solder mask. The board is fixed with two screws to the lamp body. At the center, there is a half-sphere internal diffuser covering the colour LEDs.

The same board, now removed from the lamp body.

While Zigbee Light Link is technically an open standard, these kinds of lights are primarily sold as cheap extensions to an already existing Philips Hue setup.
Ledvance was spun out off the German lighting manufacturer Osram in the mid-2010s. These days, they are owned to 100% by Chinese investors.

Time to butcher some Hue-compatible smart Zigbee lighting (and hopefully learn something along the way).

It is September 1939.
A hostile, aggressive, imperialistic foreign power has violated the borders of Poland with wanton disregard for international norms and practices. Europe, in the midst of an arms buildup, feels incapable of standing up to the aggressor.

Today near Pankovo, Novaya Zemlya. All vessels active off the west coast.

Very uncertain, but possibly two helicopters visible about 40km northwest of the launchpad, about 1.7km apart, outside sovereign airspace. What do you think @m1k3d3l7a.bsky.social?

Finally, I'd like to thank Rosatom for organising peak Burevestnik activity around my two weeks off from work.

I think it is time to get a new hobby. 🫡

About a month ago, while looking through Russian NOTAMs, I stumbled across this location on Google Earth, north of St. Petersburg: 60.352N 30.772E. It was largely constructed between 2022-2023 and while I can't offer a definite assessment, it looks like a missile test facility.

Site with lightning arrestor towers, twin layer fencing, large dome structures, one container surrounded on three sides by a berm, and four containers linked by piping in a central position. In addition to the north are two large concrete pads.

I stumbled across this location in Demyansk, Russia, around 57.68N 32.52E; it's covered by a low level (SFC-1450m) daily airspace closure between 0600-1900.

This was a civilian airstrip that had been abandoned, but appears to have been undergoing some significant work between 2023-2024.

Folks ask me how I keep up to date on major breaking events from time to time. The answer is: It honestly depends. But here are some of the best resources for monitoring events in real-time, aside from doomscrolling here or on The Bad Site. These are in no real order other than the first one...

A violent brawl during an opposition march leaves a political figure deceased in a puddle of his own blood. A year on and the event is still shrouded in mystery. In our latest, we investigate the circumstances around Dido Kakisingi’s death www.bellingcat.com/news/2024/12...
