Module PCBs assembled

By |2019-09-10T21:30:03+00:002019-09-10 20:31|electronics, modules, news, prototype, tech talk|0 Comments

Hi there, and welcome to our monthly status update!

First things first, we've finally delivered every UHK, including the ones with non-black cases! If you want to order a UHK, possibly with a non-black case, now's the time. New orders ship in a week.

As for the modules, we keep making progress. Each of the module PCBs has been assembled since our last update.

Key cluster

The main key cluster PCB didn't create any unexpected surprises.

His little brother, the key cluster trackball PCB, however, has proven to be more difficult.

The surface area of this board is merely 1 square centimeter or 0.15 square inch. This is not a whole lot of room for a dozen components, and we can't make it larger due to the lack of space.

The PCB fab kept rejecting this board because the components were too close to the edges. The only solution was to use smaller magnetic sensor (which detect the rotation of the mini trackball). 

We ended up using a sensor with the HVSOF5 footprint, which is ridiculously small compared to the other components we use. I'm waiting for this part, and it'll be quite an exercise to solder it. But I'm ready for the challenge, and so is my new microscope.

Trackball

The trackball board came out pretty nicely. It's also completely useless, unfortunately.

While soldering the parts, I realized that the pinout of the ADNS-3530 optical sensors is backwards. The datasheet features the "top side" of the component, but as far as we're concerned that's the bottom side. Unlike trackballs, regular mice probably use this component in a reverse-mounted fashion, hence the misunderstanding.

Istvan has redesigned this board, and it'll be fabbed soon.

Trackpoint

There's not much to say about the trackpoint PCB. I haven't found any issues yet. I think it'll work well once I write firmware for it.

Touchpad

The touchpad PCB has turned out pretty well, too.

This board is hardly our final iteration though. Azoteq, the manufacturer of the IQS572 touch sensor IC that we use, reached out to us and offered to review our design.

They made suggestions on how to improve the ESD immunity of the design, but perhaps even more importantly, they suggested to use a finer pitched sensor matrix to improve the resolution and increase the sensing area of the touchpad.

We plan to implement their suggestions, and then we'll send some samples to them for further review. The sensor IC is very sophisticated and has a myriad of configuration parameters, so having it tweaked by Azoteq will be extremely helpful. Azoteq provides the best support I've witnessed so far, and I'm very impressed by them.

As previously mentioned, we don't have an ETA on the modules yet. We keep making progress, and we'll announce the ETA when the time comes.

Module PCBs are ready

By |2019-08-13T20:40:32+00:002019-08-13 20:40|design, electronics, features, modules, news, prototype, tech talk|4 Comments

Hi there, and welcome to our monthly status update!

István, our PCB designer, has been on steroids, and he finished the PCBs for every module! The boards are being fabricated right now, and are expected to arrive in a week – at which point I'll assemble them.

We already showed an inside look of the key cluster module in an earlier post, so this time, I'd like to showcase the right-side modules. I'll feature three images per module: the assembled version, the half-assembled version, and the latest PCB which is being fabricated.

Please note that the following modules are only prototypes. Their color is not representative, and neither is their surface quality, which will be way smoother once the modules get injection-molded. The color of the PCBs will also differ, as we'll use black soldermask for the final boards.

Trackball

The trackball only has a single PCB. It utilizes the ADNS-3530 optical sensor, which happens to be the most compact optical sensor according to my knowledge. The retaining ring can be removed by rotating it counter-clockwise, so one can easily clean the ball.

Trackpoint

The trackpoint is composed of two boards. The top board is provided by our supplier and contains the actual trackpoint module. The bottom board is designed by us, and its purpose is to do protocol translation between the PS/2 protocol of the trackball PCB and the I2C module protocol of the UHK.

Touchpad

The touchpad module is composed of two boards. The bottom board is a trivial one which simply routes the pogo pin header to an FFC connector, supplying power and data to the top board. The top board does the actual sensing using the Azoteq IQS572 touchpad sensor IC. The top side of the touchpad will be covered by black film.

When I said that that the boards are ready, what I really meant is that these boards should be fully functional. Their design is not set in stone yet, but we expect only very minor changes going forward. Even our mechanical design is fairly advanced and should contain the mechanical features needed for injection-molding.

As I previously mentioned, we don't have a solid ETA on the modules yet. As you can see, we're making rapid progress, and we'll get there, but we surely won't rush them, as we want to get them right.

How to use macros on the UHK?

By |2019-07-17T23:29:24+00:002019-07-17 23:28|agent, features, howto|1 Comment

Once in a while, we get emails asking how to use macros on the UHK, so let's see how.

First up, the macro has to be created. You can see some default macros under the Macro section of the sidebar. You can add new macros with the plus button.

Second, you have to assign the macro. You can assign a macro to any key of any layer of any keymap. Let's say you want to assign the "Go to UHK site in browser" macro to the Q key of the Fn layer of the "QWERTY for PC" keymap. This way, the macro can be triggered via Fn+Q.

To assign the macro, simply go to the target keymap, choose the target layer, and click on the target key. Then the key action popover will appear. Click on the Macro tab, choose the desired macro, click on the "Remap key" button, and finally click on the "Save to keyboard" button that appears in the bottom right corner.

You've made it! Happy macroing!

Module prototypes galore

By |2019-07-10T20:00:30+00:002019-07-10 20:00|design, modules, news, prototype|4 Comments

Hi there, and welcome to our monthly status update!

We've been making quite a bit of progress with the modules, and have mechanically prototyped the key cluster, trackball, and trackpoint modules.

The overall mechanical design, the shape of the PCBs, and the way the PCBs are interconnected inside the modules are pretty much finalized at this point.

All of these prototypes are 3D-printed, and even though we use state-of-the-art SLS (selective laser sintering) 3D-printing technology, their quality, finish, and accuracy is a far cry compared to the final injection molded plastic parts. To give you a reference point, this is how the final key cluster module is expected to look.

Right now, the key cluster prototype features a PCB without traces, only meant to be used for mechanical prototyping. But we've designed a functional PCB in the meantime, sent its design to the fab, and the manufactured PCB should arrive in a couple of days. This will allow us to make a fully-functional key cluster prototype.

Similarly to the key cluster module prototype, the above trackball module is only a mechanical prototype, but the functional PCB has been designed in the meantime, was sent to the fab, and should be manufactured soon.

The design of the the trackpoint module PCB is in progress, and we'll submit it to the fab as soon as we can. Afterwards, the touchpad will follow.

Let's see some UHK pictures with the modules mounted.

We're super excited to see the modules coming to fruition after such a long time. I'll make demo videos as soon as we're ready with the functional module prototypes. We still don't have a solid ETA on them, but we'll be keeping you updated.

Key cluster and trackpoint module progress

By |2019-06-14T00:20:19+00:002019-06-13 23:23|demo, design, electronics, firmware, modules, news, prototype, tech talk|6 Comments

TL;DR: We've been making progress with the key cluster and trackpoint modules. New orders ship in a week, except non-black UHK cases.

Hi there, and welcome to our monthly status update! Let's get right to it!

Production status

If you want your UHK shipped in a week, you should pick the black UHK case option. Otherwise your order will take longer due to temporary parts shortages. This shortage was mentioned in our previous monthly update, and we've been working on resolving it, but it's taking more time than anticipated.

If you have any questions about the ETA of your order, please do read the delivery status page. We keep this page up-to-date, and we're unable to provide more accurate information, not even if you email us.

Module progress

In our previous monthly update, I included a picture of the development board for the key cluster module. In the meantime, I've also written firmware to drive it, so here comes its obligatory demonstration:

From a technical standpoint, the BlackBerry trackball is an interesting little beast. The ball itself is not even electrically connected to the PCB. Instead, its four spindles rotate when pushed in the four directions. The spindles contain magnets which alter their magnetic fields about 9 times during a 360 degree rotation, and the alternating magnetic field is detected by the hall-effect sensors on the PCB.

Given its limited resolution, the BlackBerry trackball is hardly an ideal device for controlling the mouse pointer (right-sided modules will perform far better in that department), but it's very well suited for scrolling in every direction. I'm actually surprised how well it's already working, even though it's the first working prototype. Over time, we'll make the acceleration and speed of the mini trackball configurable, which will make it even more useful.

As far as the firmware goes, firstly, I slightly extended the UHK module protocol responsible for the keyboard halves and modules to communicate with each other. This allowed for the transmission of not only key states, but also pointer movement information. Then I wrote a driver for the BlackBerry trackball purely using interrupt handlers, which is the most efficient approach there is. Finally, I made the key cluster transmit the pointer movement information of the BlackBerry trackball to the right keyboard half which is the brain of the UHK.

The above pictures feature our most recent mechanical key cluster prototype. The creation of a working PCB is underway.

We've also made a mechanical prototype of the inside of the trackpoint module:

We may change the trackpoint component depending on various design constraints, but the overall mechanical design is expected to be close to final.

We've actually made progress with every one of the modules, but haven't yet prototyped the others. We'll be sharing all their juicy details in our upcoming newsletters.

Mapping a virtual numpad on the UHK

By |2019-06-06T21:29:45+00:002019-06-06 21:26|agent, features, howto|0 Comments

People ask from time to time whether we provide a numeric keypad. The answer is no, but one can create a virtual numpad very easily in Agent, the configurator application of the UHK.

See the following screenshot. The numpad is mapped to the Fn layer, and its keys are laid out in a familiar fashion.

The big advantage of a virtual numpad is that one doesn't have to reach out all the way to the other side of the keyboard. This results in increased productivity, and the mouse is much closer, too. That is, if you even use a mouse after mastering the UHK mouse layer.

New orders ship in a week

By |2019-05-16T21:20:32+00:002019-05-16 20:25|design, electronics, firmware, modules, news, prototype, tech talk|5 Comments

TL;DR: We caught up with pre-orders, and new orders ship in a week! Our customers made some awesome carrying cases for their UHKs. The UHK mouse mode is surprisingly useful, and viable for creating digital art. We're making progress with the key cluster module.

Hi there, and welcome to our monthly status update! Ready for warp? Let's punch it!

Production status

We're thrilled to say that we've finally caught up with pre-orders, and incoming orders now ship in a week!

There are two exceptions regarding order parameters, though. If you want your UHK shipped in a week, you should pick the black UHK case option and a non-blank keycap printing option. Otherwise your order will take a bit longer due to temporary parts shortages. Feel free to check out the delivery status page for more information.

Please note that the order numbers have been removed from the delivery page. If your order hasn't shipped yet, it's because of the above exceptions. According to the delivery status page, you can shoot us a mail to change your order parameters to expedite delivery.

DIY UHK carrying cases

Some of you shared your DIY UHK cases, and they're so awesome that I ended up writing a dedicated blog post about DIY UHK cases. I'm very impressed by these cases, and I'm sure they're of interest of many UHK owners.

Creating digital art with the UHK

There are few keyboards with a dedicated mouse mode, and the UHK might just have the best implementation of all. Brandon Yu's drawing is a testament to this.

I'm super impressed by Brandon's work, and wouldn't have ever thought that anyone would create such a beautiful drawing purely with the UHK.

The UHK mouse mode will never be as good as a dedicated mouse, but it's surprisingly capable in the right hands. This is due to the implementation of the mouse pointer acceleration and its number of configuration options.

Key cluster module progress

We've been making progress with the key cluster module. András got the latest CAD model 3D printed, and we're glad to say it's more robust than ever.

In the meantime, I've been doing some electronics prototyping.

On the right side, you can see a breakout board designed by SparkFun, featuring a BlackBerry trackball – the kind of mini trackball that will be put into the key cluster. It's wired to an old hand-soldered UHK left half. The left half of the UHK is just like a module from an electrical, firmware, and protocol standpoint, so it's a great development board for modules. The design of the key cluster PCBs is in progress, and this is the whole Frankenstein keyboard on my desk:

(Yes, my UHK is backlit. We'll release a backlight upgrade kit eventually.)

I also started to extend the firmware, and created a dedicated project for the key cluster module based on the firmware of the left keyboard half. The two projects contain a lot of duplicate code right now, so I'll be gradually extracting the shared code to a module API which will be consumed by all the modules.

Your feedback

You've been sharing more than your fair share of tweets over the last month. Thanks so much, and as always, please keep them coming!

We'll be keeping you updated on all things UHK, and we're looking forward to talking to you on 2019-06-13.

DIY UHK carrying cases

By |2019-05-19T16:01:51+00:002019-05-01 15:20|howto|0 Comments

We get requests from time to time to provide a carrying case for the UHK, and we'd like to offer a case, but there's way too much on our plates nowadays, and we're not sure when we'll be able to offer one.

Fortunately, this didn't stop our awesome customers from making their own cases, and boy, these cases are amazing! I'll feature three cases below.

UHK case

If you have a UHK without a UHK palm rest, then look no further than @contracode's case, and make sure to check out his tweet for instructions.

UHK + Palm Rest soft case

If you have a UHK with a palm rest, then Stephen Walsh's case is probably the best choice for you. See his tweet.

Since writing this article, @z0nelevel let us know that the UHK and the palm rest fits into many 13 inch notebook cases like this one:

UHK + Palm Rest hard case

If you have a UHK with a palm rest and you're willing to spend more on a robust case, then Cole Chamberlain's case should be a great option which he made from a Pelican 1085 hard shell case. Check out the relevant Twitter conversation.

We're never ceased to be amazed by the ingenuity of our customers. We're still not sure when we'll be able to provide an official UHK case, but the above should be more than adequate in the meantime.

Catching up with pre-orders

By |2019-04-18T23:49:46+00:002019-04-18 21:01|manufacturing, modules, news|0 Comments

TL;DR: We've been making rapid progress with manufacturing. We've shipped six mini batches since our last monthly update, two additional mini batches are assembled and we will ship them next week. Afterwards, only three mini batches remain to be shipped, and we'll be caught up.

Hi there, and welcome to our monthly status update! Ready for warp? Let's punch it!

Manufacturing progress

Since our last monthly update, we've shipped mini batches 59, 60, 61, 62, 63, and 64, which is decent, but not as many as we had expected.

Mini batches 65 and 66 (the latter is not displayed on the delivery status page yet) are already assembled, but we're waiting for palm rests. Our palm rest supplier is behind schedule, and is expected to ship enough palm rests next week to complete these mini batches. (We ship individual packages as quickly as we can, so no need to email about this, folks.)

Afterwards, we'll only have to assemble about three mini batches. Should the Keyboard Gods show their support, we'll catch up then.

That is, excluding orders which contain non-black cases. Those may take a bit more time. Which brings us to the…

Non-black case shortage

Due to a temporary shortage of non-black cases including non-black UHKs and non-black extra UHK cases, orders including such items are delayed until non-black cases roll into our factory. We emailed the affected customers, and offered them the option to switch to black cases to expedite shipping. So the opportunity is there. If you want to switch to black cases, just let us know along with your order id.

This shortage is expected to be resolved in about a month, and we don't expect that a similar shortage will happen again. We ordered literally tons of colored plastic pellets, so we may not run out for years.

Module progress

András has refined the mechanical design of the key cluster module and ordered a 3D printed version of it which has yet to arrive. Then we'll evaluate the robustness of the new design. Based on the CAD models, the design looks good. We shall see soon.

The mechanical design of the right-sided modules is being finalized, too. Some details are still unclear, but András made major progress recently, and we'll get them 3D printed, too. The bottom part of these modules look very similar, and we want to have a shared bottom part for them in order to minimize tooling costs and increase reliability.

The design of the modules is rapidly shaping up, and I'll have to develop the key cluster firmware soon.

Your feedback

Twitter was noisy, which has become usual when we ship a decent number of orders. Thanks everyone for sharing your nice tweets, and please keep them coming!

We'll be keeping you updated on all things UHK, and we're looking forward to talking to you on 2019-05-16.
