A Physical Knob For Browser Tabs

April 30, 2019 by 35 Comments

If you’re like most of us, you have about twenty browser tabs open right now. What if there were a way to move through those tabs with a physical interface? That’s what [Zoe] did, and it’s happening with the best laptop ever made.

The hardware for this build is simply an Arduino and a rotary encoder, no problem there. The firmware on the Arduino simply reads the encoder and sends a bit or two of data over the serial port. This build gets interesting when you connect it to a Firefox extension that allows you to get data from a USB or serial port, and there’s a nice API to access tabs. Put all of this together, and you have a knob that will scroll through all your open tabs.

This build gets really good when you consider there’s also a 3D printed mount, meant to attach to a Thinkpad X220, the greatest laptop ever made. At the flick of a knob, you can scroll through all your tabs. It’s handy if you’re reading three or four or five documents simultaneously, or if you’re just editing video and trying to go through your notes at the same time. A great invention, and we’re waiting for this to become a standard device on keyboards and mice. Check out the video below.

A Personal Fight Against The Modern Laptop

January 26, 2017 by 206 Comments

If you haven’t gone laptop shopping recently, you’re in for a big shock when you do. While the current generation of MacBook Pros is rightly torn to shreds for being an overpriced machine with a stupid gimmick of a Touch Bar, there are issues with laptops across the industry. No one has figured out how to take a high-res iPad screen and add a keyboard, most laptops with a display smaller than 13 inches are capped at 720 resolution, new features are introduced at the expense of old ones, binary blobs are cast into a web of BIOS whitelists and missing drivers, No, the Microsoft Surface doesn’t count, because while it’s a nice machine it’s a tablet with a keyboard, not a laptop.

After months of searching, [Hamish Coleman] found the closest thing to a perfect laptop. It’s a Thinkpad X230 from the ancient days of yore, or 2012 depending on how you’re counting. It’s close to perfect, though: aside from an old CPU and GPU, the only real show stopper is the keyboard. Replacing that keyboard was [Hamish]’s personal fight against the modern laptop (YouTube, embedded below), and he’s making it easier for us to fight against the current crop of craptops, too.

Making A Thinkpad Great Again

August 26, 2016 by 42 Comments

The Thinkpad X220 is almost a perfect laptop. The X220 is small, light, was the last small Thinkpad to use 35W CPUs, has great Linux support, incredible battery life, and can be found used very inexpensively. For the Thinkpad Mafia, the X220 is a badge of honor, but it does have one glaring drawback: the LCDs in these laptops are capped at 1366×768 resolution.

A few wizards in Japan and China have taken up the X220 and developed an adapter to give this tiny laptop the display it deserves. Mentions of a FHD mod – the Lenovo-speak for a Thinkpad display upgrade – can be found on Taobao, but the anglosphere doesn’t get these cool toys. [Vectro] decided his X220 wasn’t up to snuff and decided to build his own Thinkpad mod to give his trusty companion a bigger and brighter display. He succeeded, and did it in a way that’s much better than any previous attempt.

Stock, the X220 uses an LVDS bus for internal video, and there aren’t enough lanes on this bus for a 1080 display. The usual way of modifying the X220 for a display with higher resolution is tapping into the eDP present on the Thinkpad dock connector. [Vectro]’s solution differs slightly from the usual way of doing things – instead of using an I2C EEPROM to report the resolution, DPI, and model of display, he’s using a microcontroller. This gives him the ability to control the power state and brightness level of the display. It’s a great solution, and is designed to be a relatively easy drop-in mod.

The new display works, and Thinkpadding at 1080 is awesome, but there’s still work to be done. The dock connector is incompatible with this mod, and hopefully scaling this up for small-scale production. Producing a few X220 FHD kits is going to be a problem, as each wire in the eDP cable is individually soldered to the connector. It doesn’t scale well, but there is certainly a demand to make the greatest Thinkpad even better.
