[IC] Anchor – Volume control with built-in USB Hub
« on: Fri, 03 July 2020, 18:13:08 »
Anchor
246366-0
Hi, I’ve been designing a QMK powered volume control pad that has a USB hub built-in.

246368-1
This is a 3 ports unpowered USB 2.0 hub intended for wireless keyboard or mouse receivers, it also able power wired keyboards or mouse with low power consumption.

246370-2
This 48mm knob is selected in the design; it can be replaced with 48mm knob on the market.

246372-3 246374-4
It supports 2u and 2 x 1u configurations.

246376-5 246378-6
Next to 60% and MX Vertical for scale. Dimension TBC.


It constructed with bead-blasted, black anodized aluminium.
Since this could be my first time hosting a group buy, I’m keeping it simple; only one colour will be offered. Let me know what you think!

I love the giant knob and the usb hub. Personally not a fan of the beveled edges. How would this plug in to a computer? would you just connect it to one of the usb ports on the front?

I would suggest 3 buttons so that you could program them to play/pause, previous track, next track

1 thing I missed when using a 75% (back on a fullsize now) is being able to quickly and blindly slam on the numpad enter with the thumb of my mouse holding hand.
So this would be nice if the wire could route to the top (knob side) so the button would be on my mouse side.

I'd use 1 USB port for my FIDO authentication key, 1 for easy access to plug in a flash drive and maybe get a short 6 inch cable to plug in my keyboard.

I see that you mentioned only one color, really no chance to have another one?  (WHITE IS HOT)

This is the knob macro that makes more sense than others to buy, purely because of the usb ports, it would be very sad to have to miss it for the color or just buy it and powder coat it later

I would love one of these if it was a 3.0 hub instead of a 2.0 hub.  The idea is fantastic though.  I could easily see adding this to my office setup once I get back into my office.

There will a mini usb / usb c on the back for connecting to a computer.

I thought about it, but it'll be too big for 3 ports hub.

Ooh, I like this. I often need hubs and the big knob looks great.

I'd love to have more colours, finding a manufacturer to produce accurate and even colour anodization is the hardest part of the project, especially in UK, where I'm based in.

I'm considerating powder coating in UK, but the numbers of colours will impact the powder cost if GB order number turns out small.

Also, to keep the cost down, I selected an off the shelf aluminium knob from Aliexpree/Taobao - which you can see in the renders. It will be a mismatch between the case and the knob If I go for powder coating.  I may consider offer case only kit, so they can buy their own knob.

The intention of the hub is for plugging in wireless mouse/keyboard receivers and place it on the desk where is close to the devices. Think of it's like HHKB built-in USB hub.

USB3 port is not ideal for wireless receivers as it emits frequency that interferes wireless signal. I know it could be plug into usb2 port but It's a new level of complication of making a usb3 hub, like power supply and etc...

Will this have an additional layer of complexity where this hub can be switched between two or three PCs / laptops? It would certainly add a lot of utility and attractiveness to this product.

Now there's this, ROTR, CU7 and Soap in the pipeline.

I am definitely interested, but will only get one of these. USB hub is a plus so I see this as a competitor to CU7 which has gone into radio silence.

2 keys is enough for me  :thumb: I see that as an advantage.

Not a big fan of the beveled edge either, but that's not a deal breaker. This would come down to pricing and when the GB will be available.

I've been looking at a macropad-hub with knob, and this one is absolutely what i was looking for! Unless is very expensive, i will totally but It if its available.

I recommend you make a post about this on the subreddit of mechkeyboards so people will know about the project!

Other color options would be nice,  grey or silver.

Second this. I can never have enough USB 3 ports. Are they just more expensive?

This looks perfect for me at work, maybe this can be fulfilled before I return to the office.  :p
Definitely interested, watching the thread.

The issues with this device acting as a USB 3.0 hub were briefly referenced earlier in the thread but to elaborate:

The two main issues are: 1) Power and 2) RF Interference

The power issue is fairly straightforward. If I remember the spec correctly, each USB 3.0 port must be able to supply between 150mA and 900mA of power at 5V. Thus, this device would have to be capable of supplying up to 13.5 watts of power to act as a hub, necessitating an external source of DC power and/or being limited to functioning only when connected to a host device port supporting USB-PD.

The RF interference issue is slightly more complex. There is a known issue with USB 3.0 ports generating interference in the 2.4 GHz ISM band. The OP seems to be averse to the amount of testing that would be required to properly implement an RF shielded USB 3.0 Hub while satisfying the design criterion of "a 3 ports ... USB ... hub intended for wireless keyboard or mouse receivers". There are mitigation methods available which would allow the stated design goal to be realized, but they add cost and implementation complexity.

While it is possible, though poor engineering practice, to simply apply mitigation measures like a fully enclosed receptacle shield and hope they are sufficient, I imagine it would add a not-insignificant cost to have the design properly tested in an RF absorber chamber, likely multiple times during prototyping.

In any case, the RF design considerations necessary to satisfy the original design criterion are non-trivial so I can appreciate the OP's reluctance.

More details on the RF interference issue can be found here, among other places: https://www.intel.com/content/www/us/en/products/docs/io/universal-serial-bus/usb3-frequency-interference-paper.html

Edit: Added a missing preposition.

That makes me wonder how CU7 intends to implement that feature. Or are they overpromising?

If you're referring to USB 3.0/USB 3.1 support on the CU7, I read that they've dropped that feature in favor of USB 2.0 in the interest of expeditiousness.

All the way in!

Would be cool if this had sufficient weight so that it doesn't slide around the desk easily
