Yes, assembly is available. For the current group buy, you can find details for the assembly service here: https://www.slicemk.com/products/ergodox-wireless-assembly

For the planned low end version, assembly will just be installing switches/keycaps (no soldering). A similar assembly service will be available for people who just want to receive a complete keyboard.

I recently developed a high end wireless ErgoDox keyboard [1] though I'm working on a more affordable version that will be announced in March/April. It will be around $200 with all the components (some minor assembly required). If you would like to be notified, please subscribe to my mailing list [2] for "ErgoDox Wireless Lite". If you are interested in details, you can also reach me via email (see profile).

That is correct. Typically if want to update your keymap, you would just update the firmware running on the dongle. The firmware on the two wireless keyboard will pretty much never change.

https://www.xudongz.com/blog/2020/ergoblue/firmware/ has a lot more information about the controller (with photos). In summary:

- The dongle is reasonably small. If you're traveling with it, you can toss it in your bag with a battery pack and it acts as a Bluetooth keyboard (for your phone/tablet/laptop/etc). You can plug it into your desktop, in which case it acts as a USB keyboard in addition to Bluetooth for other devices (phone/etc)

- Modifiers work fine but layers don't because some software still needs to maintain state. For example you might have the layer switch key on the left but want the next key to be on the new layer on the right. Theoretically one can do this with custom software on the computer though an external controller/dongle is straightforward and doesn't need to account for OS/platform differences. It also lets you connect to multiple devices simultaneous via Bluetooth.

- There's an option for hot swap switch sockets, in which assembly is putting the case together, soldering some header pins, and popping in the switches. There will be an assembly service for people who just don't want to do it but the process itself has been thoroughly optimized that it shouldn't be difficult.

I've been working on a aluminum and wireless version of the ErgoDox and the group buy will start this weekend. It will be around $350 excluding switches and keycaps.

With DSA keycaps (the shortest possible one) the total height is 29mm (including rubber feet).

You can see the details of the earlier laser cut prototype here (and subscribe to the mailing list for updates): https://www.xudongz.com/blog/2020/ergoblue/. The details of the aluminum version will be announced when the group buy is officially announced.

You can find also my contact information on my homepage for questions and feedback.

I've been using my new keyboard for a few months now and haven't had any latency issues. Most of the newer custom wireless keyboards run ZMK (https://zmkfirmware.dev/) and latency issues are uncommon. If you are interested in making your design wireless, consider joining the Discord.

This past year I designed the ErgoBlue (https://www.xudongz.com/blog/2020/ergoblue/), a split ErgoDox keyboard that is wireless and solar powered. I'm obviously biased but I think it's a pretty unique build.

The interest check ran a few weeks ago and the group buy will run in a few weeks (group buys are essentially preorders where a certain number of quantity is required in order to achieve some economies of scale so it's not prohibitively expensive).

Took this screenshot last night: https://i.imgur.com/pl22srz.png

I would have reported it to someone at project euler but couldn't find any contact information beyond a link to an inactive forum.
