New - Glass Battery
September 01, 2017, 04:36:23 pm

I thought this was interesting for mobile gamers  ;)

John Goodenough, coinventor of the lithium-ion battery, heads a team of researchers developing the technology that could one day supplant it.
Electric car purchases have been on the rise lately, posting an estimated 60 percent growth rate last year. They’re poised for rapid adoption by 2022, when EVs are projected to cost the same as internal combustion cars. However, these estimates all presume the incumbent lithium-ion battery remains the go-to EV power source. So, when researchers this week at the University of Texas at Austin unveiled a new, promising lithium- or sodium-glass battery technology, it threatened to accelerate even rosy projections for battery-powered cars.

“I think we have the possibility of doing what we’ve been trying to do for the last 20 years,” says John Goodenough, coinventor of the now ubiquitous lithium-ion battery and emeritus professor at the Cockrell School of Engineering at the University of Texas, Austin. “That is, to get an electric car that will be competitive in cost and convenience with the internal combustion engine.” Goodenough added that this new battery technology could also store intermittent solar and wind power on the electric grid.

Yet, the world has seen alleged game-changing battery breakthroughs come to naught before. In 2014, for instance, Japanese researchers offered up a cotton-based (!) new battery design that was touted as “energy dense, reliable, safe, and sustainable.” And if the cotton battery is still going to change the world, its promoters could certainly use a new wave of press and media releases, as an Internet search on their technology today produces links that are no more current than 2014-2015 vintage.

So, on whose authority might one claim a glass battery could be any different?

For starters, Donald Sadoway’s. Sadoway, a preeminent battery researcher and MIT materials science and engineering professor, says, “When John Goodenough makes an announcement, I pay attention. He’s tops in the field and really a fantastic scientist. So, his pronouncements are worth listening to.”

Goodenough himself says that when he first coinvented the lithium-ion battery in the 1980s, almost no one in the battery or consumer electronics industries took the innovation seriously. It was only Japanese labs and companies like Sony that first began to explore the world we all today inhabit—with lithium-ions powering nearly every portable device in the marketplace, as well as electric vehicles and even next-generation airliners.

In other words, who better than Goodenough to cocreate the technology that could one day supplant his mighty lithium-ion battery?

The new battery technology uses a form of glass, doped with reactive “alkali” metals like lithium or sodium, as the battery’s electrolyte (the medium between cathode and electrode that ions travel across when the battery charges and discharges). As outlined in a research paper and recent patent filing (of which Goodenough, 94, says more are forthcoming), the lithium- or sodium-doped glass electrolyte offers a new medium for novel battery chemistry and physics.

They find, for instance, that the lithium- or sodium-glass battery has three times the energy storage capacity of a comparable lithium-ion battery. But its electrolyte is neither flammable nor volatile, and it doesn’t appear to build up the spiky “dendrites” that have plagued lithium-ions as they charge and discharge repeatedly and can ultimately short out, causing battery fires. So, if the glass batteries can be scaled up commercially, which remains uncertain in this still-proof-of-concept-phase research, the frightening phenomenon of flaming or exploding laptops, smartphones, or EVs could be a thing of the past.

Moreover, says lithium-glass battery codeveloper Maria Helena Braga, a visiting research fellow at UT Austin and engineering professor at the University of Porto in Portugal, the glass battery charges in “minutes rather than hours.” This, she says, is because the lithium- or sodium-doped glass endows the battery with a far greater capacity to store energy in the electric field. So, the battery can, in this sense, behave a little more like a lightning-fast supercapacitor. (In technical terms, the battery’s glass electrolyte endows it with a higher so-called dielectric constant than the volatile organic liquid electrolyte in a lithium-ion battery.)

Moreover, Braga says, early tests of their technology suggest it’s also capable of perhaps thousands of charge-discharge cycles, and could perform well in both extremely cold and hot weather. (Initial estimates place its operating range between below -20º C and 60º C.) And if they can switch the battery’s ionic messenger atom from lithium to sodium, the researchers could even source the batteries more reliably and sustainably. Rather tha...

Last remaining CRT monitors from X-Arcade
April 19, 2017, 09:26:11 am

Received an email from X-Arcade today that they expect to sell out of their remaining stock of CRT monitors shortly.

"LIMITED CRT MONITOR AVAILABLE

The CRT featured in our arcade machine is no longer in production and we are down to the last remaining inventory. We should be running out by end of this month, so if you wish to own an authentic CRT monitor, please order immediately! We will shift to an LCD once our remaining stock is depleted. No companies are willing to produce any more CRT arcade monitors. First come, first serve."

RatRefresh 0.1 - Automated EDID updater for MAME and others
January 12, 2017, 04:43:32 pm

I've put up a small tool that might aid LCD users to prevent tearing when gaming. We all know CRU can update your EDID settings, but that does not have command-line support. That makes it quite inconvenient to change your refresh rates for every single game you play (especially on MAME).
I have created RatRefresh to help with that. It's a simple tool that allows you to update EDID settings from commandline. What can it do?

  • Quickly switch to a specific refresh rate from command-line
  • Automatically switch to the correct refresh rate for any MAME game
  • Allows you to enter refresh rates for any emu / game / application

So this might be ideal for your LCD-powered MAME-cab! Check it out here.

Use an Arduino to de-suicide a CPS2 board
September 13, 2016, 11:52:18 am

Quote
Dear all, after a few months of testing we are extremely happy to release the new clean desuicide / security programing method for Capcom's CPS2 hardware.

This guide is the result of almost two years of work by an small group of arcade enthusiasts to unravel the secrets of the security implementation found in one of the largest and most popular arcade platform systems. Thanks for this work it is now possible to fully preserve any CPS2 systems as original hardware.

Over the coming weeks additional details about the CPS2 hardware internals will be released providing unseen insights into how Capcom implemented security.

More details, PDFs, step by step guides, and and video at the link.

Holy cow! Are we up? We look up! Are we really up?
August 22, 2016, 07:35:32 am

I *think* we're up! I'm going to leave the server in maintenance mode for a while, possibly all day, while I make sure we're reliably up and stable and that everything's working. I'm positive there are things that aren't working yet, for instance the wiki. However, the main site and forum appear to be online. Thanks for bearing with me folks while we worked through our outage.

What happened?

The hard drives in the RAID configuration on the old server died, one at a time. We replaced them, but somewhere in the replacing we lost the boot partition, and despite the fact that it should be relatively easy to restore, we could-not-get-it-to-boot again.

Since the server was 4 years old at least, we had already been contemplating upgrading to a new box, so took the time to do so. We still had access to the old server's drives via a rescue boot environment, so migrating was doable.

It took a bit to get the new server online and configured, primarily because I used the transition as an exercise to improve my server administration skills with Linux. 

The final snag was the version of the Ubuntu we're running on the new box doesn't support the version of php SMF requires, and SMF isn't upgraded for the new version of PHP yet.

Got that resolved this morning, and now it's hopefully just a matter of troubleshooting various quirks and settings until we get everything resolved.

BIG THANKS to sirwoogie for holding my hand through this process and helping teach me to fish! :)

Several of you have offered your time or financial donations to help. Thank you, thank you, I very much appreciate it. In the future I won't be shy about accepting offers of expertise.

As for financial donations, thank you for the offers, but please consider donating to charitable organizations or those in need such as relief for the Louisiana flooding victims.

BYOAC/arcadecontrols.com is my way of giving something back to the community. There's such a wealth of knowledge and resources out on the Internet, and BYOAC is my way of being a small part of that. Maintaining the server is within my means, and as long as there's any interest in what BYOAC hosts, I'll continue to keep the server online.

Thank you for your support!

Arcade Game Review Database
July 01, 2016, 02:32:34 pm

I have decided to open up a project I have been working on for many years... it's abut 80% complete but functional.   Basically,  in about 2013 I began developing an arcade game rating and review website...

I have put many many (did I mention many) hours in to this project... as well as more than a couple hundred bucks... and it was looking like it would never see the light of day.   Basically ... I burned out.  For the last year it sat.  This year,   when the domain name came up for renewal... I decided I was going to put the damn thing online and see where it goes.  If it sees moderate success,  I will buckle down and complete it.

Essentially all letters have been populated minus the letters S and T.  Unfortunately... there are "A LOT" of S and T games.  That said,  the names are there,  just the data within each record hasn't been added.  It's a long tedious job... but one I am willing to do if the site is used.

I really think that it could become a useful tool for collectors if we get enough participation from the community.   Basically,  it will become what the community makes of it.

I am still working on a bug or two that cropped up when multiple people started reviewing,  but they'll get handled.  I am also open to suggestions, etc.   

Feel free to take a look and if you'd like to help the site reach it's potential,  sign up and review a few games!

Thanks!
