can you provide more information on the mounting system?

i would check the traces from the controller to the switches, then the diode, then resolder the controller (only when comfortable with soldering surface mounted components).

What's with this "carbice" racket, <vertically aligned carbon nanotube cooling sheets>

The CLAIM: Trade performance for durability??

This is ridiculous, if PTM is just as good over the 5-10yr OBSOLESCENCE lifespan of a CPU, while performing 6 Celsius better, what use is carbice for the desktop market?.


It's like saying, I've built the hinges on my refrigerator to last 1000 years. OK, humans killed each-other 900 years ago, but you've still got those hinges for the refrigerator that doesn't cool anything where there's no food on a Dead-Earth for anyone..

Interesting, I have previously seen sliding palm rests of plastic/foam with teflon pads underneath. A premium variant of that concept would be something.

I have also had a pair of "ErgoRest": rests on mechanical arms clamped to the desk's edge, that allowed some movement. However, if you stretched the linkages too far, they instead provided resistant to sideways movement, so I found them to be more of a nuisance than help.
I think I had found them at a thrift store, and gave them away to a board member.

9070GRE, they're going with $550, that's a NO.

9070xt at $650, no competition.

Glad to see Alps getting some attention! I'm in for two kits.

CRTs have a unique look, but have mostly disadvantages at this point.

The motion clarity is also now rivaled by Oleds.

Prior, with 60fps locked games, Oleds couldn't match CRT, but now with Beam-Simulator shading, it's as good if not better.

01.06.2026 UPDATE

Hello everyone !

We've been quiet since the end of the GB so  here is an update for you on how things are progressing.

TLDR: all is good, production is starting :)
The below is a "journal" of the backstage if you're interested to know the process in detail:

- Following the GB end, it took a few days/weeks for vendors to input all their numbers to a google sheet

- Once we got the final numbers for everything, we had to go back to each supplier and manufacturer to lock their prices. Some suppliers are updating their pricing daily/weekly based on the market so we couldn't do that until ready to pay.

To give you an idea, we are talking about 4 manufacturers (CNC machining and anodization / rubber feet, silicon insert and foam pads / packaging boxes / and PCBs fab) and 4 suppliers (batteries, electrical components, solenoid, hotswap sockets)

- Hongtu agreed to pay upfront for most suppliers that had regular updates on their prices otherwise it would have been impossible to know how much to charge vendors back as by the time a vendor would pay his invoice, the price would have changed.

At the same time there was then a big accounting to do to charge back the correct amount to each vendors. Basically, 4 manu + 4 suppliers to be charged on 9 vendors with different quantities... That was a hell of a job.

- Once this was sorted invoices for pre-payment were sent to vendors and most of them have now been paid - the remaining are in the process of being taken care of.

- Hongtu has advised the raw material have been ordered and production will start as soon as it's been received.

- Production of batteries is completed and these have been shipped to Hongtu this morning.

- All packaging boxes have been produced but waiting for the EVA foam cutting to be completed before final assembly of those. All stickers have been made.

- Production of rubber feets / foam pads / silicon insert is nearly completed.

That's all for now  :thumb:

The goal is to be able to slide your palm about 1 Inch in all directions...
If that is the goal then the lower part must be bigger by 1 inch in all directions compared to the upper part. The pictures do not indicate that at all.

Also the picture indicates that the ball sits in the upper bearing depression:
1) if the depression is simple spherical cutout then you will get sliding friction there and it is likely to be too much for smooth motion (even if it is made from a low friction material like e.g. teflon)
2) if the depression is a groove (shown from the direction of the groove ... therefore seen on the picture as a simple spherical cutout) then it will allow easy movement only in one direction (the direction of the groove)

If you want to have a friction less feeling with balls then the balls must be able to move as well. E.g. to move the pad to the right by one inch the ball must be able to move to the right by half an inch! This is true for any direction.
You do not have any indication in your pictures that you allow for this.

Look .e.g. at this exploded view of a linear bearing:

Notice that the bearing balls are there in "squished" loops. The balls mus be in loops since one side of the loop provides the return path for the moving balls. The other side of the loop actually is the working area. This is the area where balls provide friction less movement between the carriage a the rail. They provide the friction less movement by rolling between the rail and the carriage surface. But because of this rolling they are also moving along the loop. Therefore they need the return path. The balls are exiting the working area of the loop ... returning through the return path  and entering the working area on the other side.

Balls move through the working area without friction since they are rolling. This is also the area where the balls are under load (possibly high forces between carriage and rail). The balls are not moving without friction in the return path. But the friction is very low there since there is no load on the balls.

Your design does not address the moving ball problem at all. That is the reason I pointed out other options (magnetic levitation, ...).

Local pickups are the go-to for CRT tvs. There's always some granny who kept a giant CRT in a room for 40 years, you just need to pick it up usually.
Maybe in EU it is more difficult finding old CRTs, and it is getting harder every year in the US as well
