As the United States’ pinnacle of extravaganza, the Las Vegas Strip and the rest of the town of Paradise are on a seemingly never-ending quest to become brighter, glossier and more over the top as one venue tries to overshadow the competition. A good example of this is the ironically very uninspiredly named Sphere, which has both an incredibly dull name and yet forms a completely outrageous entertainment venue with a 54,000 m2 (~3.67 acre) wrap-around interior LED display (16 x 16K displays) and an exterior LED display (‘Exosphere’) consisting out of 1.23 million LED ‘pucks’. Although opened in September of 2023, details about the hardware that drives those displays have now been published by NVidia in a recent blog post.
Driving all these pixels are around 150 NVidia RTX A6000 GPUs, installed in computer systems which are networked using NVidia BlueField data processing units (DPUs) and NVidia ConnectX-6 NICs (up to 400 Gb/s), with visual content transferred from Sphere Studios in California to the Sphere. All this hardware uses about 45 kW of power when running at full blast, before adding the LED displays and related hardware to the total count, which is estimated to be up to 28 MW of power and causing local environmentalists grief despite claims by the owner that it’ll use solar power for 70% of the power needs, despite many night-time events. Another item that locals take issue with is the amount of light pollution that the exterior display adds.
Although it’s popular to either attack or defend luxurious excesses like the Sphere, it’s interesting to note that the state of Nevada mostly gets its electricity from natural gas. Meanwhile the 2.3 billion USD price tag for the Sphere would have gotten Nevada 16.5% of a nuclear power station like Arizona’s Palo Verde (before the recurring power bill), but Palo Verde’s reactor spheres are admittedly less suitable for rock concerts.
This year’s CES has dredged up some memories. I had assumed that as one becomes old they are supposed to become used to memories of a young vigorous person that shared their body and memories leaving little else except some scars and some old stale socks lying around plus 2 or 3 pictures to prove it was in fact not a series of hallucinations. Turns out you don’t get used to it, you just endure.
30 Years ago was our CES: Commodore had the reputation of showing something new every CES and this was a time when a Home Computer meant a Consumer Computer. I have written before about how we endeavored to make sure other’s failures didn’t become ours and we did in fact make it, just in time, to the ’85 CES with what became our flagship computer, at least for the next 4 days.
To the Very Last Minute

When I say made it just in time I am counting people hand carrying the last ten or so homebrewed and MOS cooked 80 column chips either the night before or that very morning. The C128 computers where waiting lined up and open in the room seen below; cases agape much like a row of baby birds waiting on whatever engorgement MOS had come up with for us as the seconds counted down.
And then finally we stood on the second floor of our booth (yes they built a 2 story structure for us in a couple of hours the night before) surveying the now working computers; C128’s and the never released LCD machine, when the last “issue” before the doors opened arrived; a Marketing person (panting) telling us of “yet another C128 failure” though she couldn’t actually point to any previous computers that had failed. We wouldn’t let her continue with her complaint until she retracted the previous general statement of failure, more on principle than actual meanness.
The “Prep” room now empty, every CES C128 computer came through here. Note the EPROM burner and disks taped to the wall along with a residual Coors beer can
As with most highly technical in-the-field fixes this one was something to remember. My last act of “the ’85 CES show” became the simple motion of walking up to the “failed” computer station and pressing the key changing the C128 back to 40 column mode, especially important since it only had a 40 column monitor attached to it.
End of Line
Then something happened: We were done. I felt sub-processes actually end that had been consuming both CPU and I/O for months, I was suddenly unencumbered by the next “must fix”. I didn’t have a next task to pop from the stack… the phrase “End of Line” came to mind.
I was 24, in Las Vegas and had just delivered one of the major products for the best computer company in the world to the only show that mattered to us. I started walking towards the door with the uncommonly bright Las Vegas sun streaming through the windows. There were lines of people around the block waiting to enter, but the exit was completely unobstructed.
I buried myself in Las Vegas in a way that only youth, testosterone, and adrenaline can enable.
Making the Rounds
Thats me with the long hair and the girl (Judy Braddick, a somewhat brilliant Game Programmer). Note the bottle of Tequila and empty beer bottle sitting on the table in the Las Vegas airport. Greg Berlin is on the left standing two feet taller than normal humans. (Hedley Davis of Xbox fame in the foreground). It was a good CES.
I won’t report here much of what all was done over the next days as I understand that for some things the statute of limitations never truly runs out, but inspired by [Mike’s] reporting of visiting the suites of the companies I will relate one small tale here: I had grabbed my best friend and fellow hardware designer who was the father of the 1581 disk drive, also successfully released on this day, and headed out. With the 6’8” [Greg Berlin] (grandson of the designer of the Curtis Wright P-40 Warhawk) in tow we started hitting the floors of the local hotels looking for the suites of the “important” companies that never managed to personally invite us. We had a secret weapon that opened doors as if bribed; not in Greg’s towering presence but in the simple phrase: “we’re from Commodore”.
Doors fully opened that had previously opened only 12-14 inches only to stop on the shoe of the doorman, and 5.25” floppies were stuffed in our pockets like the $20 bills of a VIP trying to impress his date. The suite that comes to mind was that of Electronic Arts (EA). With backslaps and copies of this year’s (and a few of last year’s) C64 game floppies shoved in our pockets we were welcomed like old friends; appointments were made and more than a couple of chugging contests were held. They lost or at least didn’t better us as we were young and full of testosterone.
As we made ready to leave the good folk of EA, after making sure that we would swing by their booth the next day (we did), they asked if there was anything they could get for us. This may sound like a strange or gratuitous question but I had already spied the case of Michelob (a beer from the early days of 1 micron silicon) and was pointing to it before the question was fully uttered. EA grabbed the case with no hesitation as I turned to face the door so he could set the case of teardrop shaped bottles on my shoulder for me.
Back out into Las Vegas we went with Electronic Art’s beer on my shoulder… It was a good CES.
While we were at DEFCON, we had the chance to visit a few places in the area that are of interest to the Hackaday readership. We made it over to Syn Shop, the Las Vegas hackerspace.
Years ago, this area of town was home to the Greyhound bus depot, complete with all the adventures associated with that. Since then, Zappos set up their HQ nearby, massive amounts of money flowed in, and gentrification got a big thumbs up from the decaying casinos in the area. Syn Shop is just down the street from the Denny’s with a bar and the twelve story tall slot machine with a zip line, making this space perfect for the community outreach that is lacking in so many other hackerspaces. In the hour or so I was there, no fewer than two groups of people took a gander through the plate glass asking themselves if this was ‘one of those makerspaces or something’. It’s a far cry from hackerspaces found tucked away in business parks, and something that has worked well for the members of the shop.
[Andrew Bogerri] took me around the space, first showing off the PDP-11/23 which you can drive around with a remote control. Yes, it works. No, not Unix. Yes, the entire stack should weigh about 500 pounds, but the guts of the RL02 drives were replaced with something considerably more modern. Just think of it as a 200 pound remote control car, with the momentum that goes along with that.
Syn Shop has a huge space for classes, and the tutors to go along with it. Classes range from CAM design and CNC operation, to tutorials on how to use the huge ShopBot in the space. There’s also a craft night, plenty of help available for running the laser cutter, and enough electronics paraphernalia to work on anything in the sub-Gigahertz range.
Even though most of the Syn Shop members were away at the Rio getting geared up for the con when I went through, you could still tell the space is constantly buzzing with energy and spurious emissions. I caught up with a few of the other regular members at the Hardware Hacking village at the con, but that’s a subject for another post.
[Gnsart] builds props often used in the film industry. He’s created an amazing retro Vegas style light chaser sign. The sign was started as a job a few years ago. While [Gnsart] could handle the physical assembly, the cost of a mechanical light chaser pushed the project over budget. The sign project was cancelled back then, but he never forgot it.
Fast forward to a few weeks ago. [Gnsart] happened upon the Arduino community. He realized that with an Arduino Uno and a commonly available relay board, he could finally build the sign. He started with some leftover cedar fence pickets. The pickets were glued up and then cut into an arrow shape. The holes for the lights were then laid out and drilled with a paddle bit. [Gnsart] wanted the wood to look a bit aged, so he created an ebonizing stain. 0000 steel wool, submerged and allowed to rust in vinegar for a few days, created a liquid which was perfect for the task. The solution is brushed on and removed just like stain, resulting in an aged wood. We’ve seen this technique used before with tea, stain, and other materials to achieve the desired effect.
[Gnsart] then built his edging. 22 gauge steel sheet metal was bent to fit the outline in a bending brake. The steel sheet was stapled to the wood, then spot welded to create one continuous piece. Finally, the light sockets were installed and wired up to the Arduino. [Gnsart] first experimented with mechanical relays, and while we love the sound, we’re not sure how long they’d last. He wisely decided to go with solid state relays for the final implementation. The result speaks for itself. LEDs are great – but there is just something about the warm glow of low-wattage incandescent lights.
It’s just about time for CES (as we’ve mentioned once or twice), so we thought we would update you on our latest goals and ideas for the show.
This year [Caleb Kraft], [Nick Caiello], [James Munns], [Devlin Thyne], and [Brett Haddock] will be covering CES. We are currently looking for some good places to go if we get a chance to break away from the show, and while we won’t make any guarantees, we’d love to meet some of our readers! Please direct all ideas for your favorite eatery to our Contact Page. Keep an eye on our Twitter page (@hackaday) for CES updates and what your favorite writers are up to, where we are eating, and other possible chances to meet up with us.
We are also still looking for Las Vegas Hackerspaces to visit, so let us know and we would love to cover it!
Be sure to check out our updated interest list after the break, and keep sending in what you want to see!
As you already know, we’ll be attending CES this year. We’re still looking for ideas on what you, our loyal readers, want to see. We’ve gotten some good feedback, and came up with some ideas of our own. Keep sending in your ideas. Remember, it doesn’t even have to do with CES. Are there any hacker groups in Vegas that we could meet with? Any locations of interest? Let us know.
So far, we have the following requests:
Google Nexus
Notion Ink tablet w/Pixel-Qi display
Instinct Engineering – Suitcase XBOX 360, Fold out gaming couch
Car that can drive itself (most likely Toyota or Honda)
Hackaday is going to the 2010 Consumer Electronics Show in Las Vegas. This year’s show runs January 7-10 and we’re going to use every minute to scout out hacking’s past and future. We’re looking for hacks from the past that have made it into new, commercially available electronics. We also want to get a look at the products that we’ll all be cracking open at some point in the future.
Do you know of something being exhibited that we shouldn’t miss? Tell us what to look out for in the comments.
