I specifically looked for and ordered a heatsink that came with an adhesive thermal pad. Among the customer reviews of heatsinks on AE, I found other customers had resorted to installing their heatsinks with super glue. That’s a bad idea as regular super glue is a thermal insulator.

Norway must be its only market. <p>Why isn’t the Norwegian keyboard layout variant of the official Raspberry Pi keyboard accessory available for sale in Norway? Norway is the primary, if not the only, market for it. I went up the distribution chain to figure out why it isn’t available.</p> <p><a href="https://www.ctrl.blog/entry/raspberry-pi-keyboard-distribution.html#src=feed">Read more …</a></p> urn:uuid:32f01632-6e4a-4742-88f1-b4d8db7bbd98 2020-11-25T01:38:00Z 2020-11-25T01:38:00Z Rollerblade wheels are a great upgrade for your office chair Rollerblade-style wheels don’t resist movement and help you stay slightly less inactive while spending hours in your office chair. <p>I swapped out my boring old office chair double-wheeled castors for rollerblade-style wheels. I didn’t quite know what I expected, but I’m happier with my chair. The new wheels also as the potential for a minuscule improve my health; so what’s not to like?

Here are my experience from owning three projectors over the last decade. <p>I’ve owned three different projectors in the last decade.

MacBookPro11,2) had begun to swell. This is caused by a chemical reaction that happens near the end of life for lithium-ion batteries. It’s no longer safe to use it in this state as the swelling battery can damage sensitive components, and it is more at risk of being punctured and burst into a high-intensity fire.</p> <p><a href="https://www.ctrl.blog/entry/macbook-late2013-battery-replacement.html#src=feed">Read more …</a></p>
