The heatsink I ordered for my Raspberry Pi arrived with double-sided tape instead of a thermal pad; so I installed to the official case fan accessory instead.

<p>Two months ago, I mentioned that I was looking to buy a heatsink for my Raspberry Pi on AliExpress (AE). 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. In the meantime, the Raspberry Pi Foundation had released a potentially better and official cooling accessory.</p> <p><a href="https://www.ctrl.blog/entry/raspberry-heatsink-case-fan.html#src=feed">Read more …</a></p> urn:uuid:60587710-68c6-44af-896c-1738ded92c19 2020-12-30T00:21:00Z 2020-12-30T00:35:00Z

Why isn’t the Norwegian keyboard layout variant of the official Raspberry Pi keyboard accessory available for sale in Norway? 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-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 some of the unexpected benefits of replacing the wheels on my office chair.</p> <p><a href="https://www.ctrl.blog/entry/rollerblade-wheels-chair.html#src=feed">Read more …</a></p> urn:uuid:4018f176-61e4-49a2-9b69-7ac3c8a557a8 2020-11-21T01:13:00Z 2020-11-21T01:13:00Z

Projector bulbs have a limited life-time, and getting hold of them can be difficult. Here are my experience from owning three projectors over the last decade.

<p>I’ve owned three different projectors in the last decade. All of them have been your average mid-range wall-mounted home-theater projector. Fool me thrice, and I’ve finally learned my lesson and bought a TV instead.</p> <p><a href="https://www.ctrl.blog/entry/projector-lamp-trap.html#src=feed">Read more …</a></p> urn:uuid:09d1f9aa-cd2a-405d-aa22-773b13807b0c 2020-11-16T17:33:00Z 2020-12-02T11:45:00Z

The battery on my seven-year-old MacBook Pro 15″ had begun to swell and replacing it myself was way cheaper than via an authorized dealer.

<p>The battery on my seven-year-old MacBook Pro Retina from late 2013 (a.k.a. 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>
