Voor warmteontwikkeling in koperkabel was ik benieuwd wat de weerstand voor diverse diameters was.
Gelukkig heeft de Nederlandse pagina Koperdraad: Gegevens – Wikipedia deze tabel (let op weerstand is per 100m!)¹

I tried finding older versions of [Wayback/Archive] 160767437_1614740178716498_1088211482313253900_n.jpg (667×960) from Facebook: Crappy Electrical jokes and Puns. 1,666 likes · 9 talking about this.

Since around 2005–2007 Dennard scaling appears to have broken down. As of 2016, transistor counts in integrated circuits are still growing, but the resulting improvements in performance are more gradual than the speed-ups resulting from significant frequency increases.[1][10] The primary reason cited for the breakdown is that at small sizes, current leakage poses greater challenges and also causes the chip to heat up, which creates a threat of thermal runaway and therefore further increases energy costs.[1][10] Since 2005, the clock frequency has stagnated at 4 GHz, and the power consumption per CPU at 100 W TDP.

Apart from the 1973 and 1977 editions mentioned in NEN 5152 – Wikipedia it also links to a 2016 edition. After a little digging, it has at least had new editions in these years:

At the time of writing these were some 60 videos each 5-15 minutes long in reversed order (#1 at the bottom, #61 at the top).
This means it is about 10 hours of watching time well worth it.

Want: [Wayback/Archive] William Le’s Perpetual Motion Machine ver.2 – (plz visit my Amazon sto – LovelyWings
I think I like the transparent version most, but the wood versions (yellow or brown) of course have more mystery.
There are more products in [Wayback/Archive] Wooden Kinetic Sculpture for Art Lovers – LovelyWings.
You can buy some of them at [Wayback/Archive] Amazon.com: LovelyWings, for instance the brown version of the [Wayback/Archive] Amazon.com: Perpetual Motion Machine – Infinitive Marble Machine – William Le’s Perpetual Motion Simulator : Handmade Products.

Voor mijn link archief: links rondom Busch-Jaeger – 6815U schakelmateriaal (comfort, IR) via [Wayback/Archive] busch jaeger 6815 – Google Search..
Doet officieel geen LED en spaarlamp, maar schijnt meestal wel te werken. Hopelijk is dit een opstap voor schakelmateriaal wat altijd met LED en spaarlamp werkt.
Het grote voordeel van deze schakelaars plus bijbehorende functie-kapjes is dat ze tegelijk op IR+tijd en handmatig kunnen werken. Dus vanzelf aan/uit met IR+tijd, maar ook handmatig aan/uit zetten of combinaties.

[Wayback/Archive] How TINY Can I go? The BEST Power Board is here! – YouTube – GreatScott!
I will try to remake an AliExpress PCB. It is a very handy voltage converter that can take a varying battery voltage and convert it into 3.3V or 5V while only requiring very little current (25uA) on the input. Sounds awesome, but the board is way too huge. That is why I try to push the size limits in this video to the minimum.

Still to do for Michael: put the inverter on the underside of the table-top.

The picture is below; this is the part list: [Wayback/Archive] Michael Eberhard on Twitter: “@TuckiTina @MatthiasVialon AlphaSolar Komplettpaket ca. 500€ Ikea Tischbeine 60€ Holz aus dem Bestand.” / Twitter
Yield is not bad: [Wayback/Archive] Michael Eberhard on Twitter: “@truewhitemount Ich habe einen einfachen Zähler dazwischen. Gerade jetzt produziert der Tisch zwischen 180 und 230 Watt. In Summe bin ich im den letzten Tagen auf 0,6 – 0,8 kWh pro Tag gekommen. Noch ist die Motivation da, jeden Abend den Zähler abzulesen…” / Twitter
