Lenses: From Fire Starters To Smart Phones And VR

June 28, 2022 by 21 Comments

In antiquity, we see examples of magnifying crystals formed into a biconvex shape as early as the 7th century BC. Whether the people of that period used them either for fire-starting purposes or vision is unclear. Still, it is famously said that Emperor Nero of Rome watched gladiator games through an emerald.

Needless to say, the views we get through modern lenses are a lot more realistic. So how did we get from simple magnifying systems to the complex lens systems we see today? We start with a quick journey through the history of the camera and the lens, and we’ll end up with the cutting edge in lens design for smartphone cameras and VR headsets.

Retrocomputing, Time To Hang Up The Original Hardware?

June 28, 2022 by 57 Comments

For those of us with penchant for older technology, there’s something special about operating with older hardware. Whether it’s a decades-old camera, a vintage keyboard, or a home computer from the 1980s, the modern equivalent just doesn’t quite compare. But working with older parts definitely isn’t for the faint-hearted, as the passage of time has taken its toll on their reliability. Is it time to recognize that the supply of replacement vintage parts is not infinite, and to switch from using original hardware to more modern alternatives? [Retro Recipes] poses this question after a particularly difficult-to-find Amiga fault, and discusses it while evaluating a replacement Amiga made entirely from modern parts.

The new Amiga in question is a recreation of an A1200 with a re-manufactured case and keyboard, and the guts of an A500 Mini retro console taking the place of the Commodore board. He goes through the process of making an Amiga hard drive image on a USB drive using the image from his original drive in his teenage years, and boots it both on the 500 Mini based machine and on the UAE emulator on a Mac laptop. You can follow him in the video below the break.

We can see the logic in treating original hardware as a precious resource that’s not to be run up for fear of breaking it, but by the same token we’re still standing by that first sentence. But should the enjoyment of an older machine be limited only to those who have an original? We think not, so if enjoying an Amiga without an Amiga can be as good as the real thing then we’re all for it.

Of course, for those whose original Amigas have already broken, there are other ways to bring them back.

Reverse-Engineering Forgotten Konami Arcade Hardware

June 28, 2022 by 4 Comments

When fully-3D video games started arriving in the early 90s, some companies were more prepared for the change than others. Indeed, it would take nearly a decade of experimentation before 3D virtual spaces felt natural. Even then, Konami seems to have shot themselves in the foot at the beginning of this era with their first foray into 3D arcade games. [Mog] shows us the ins-and-outs of these platforms while trying to bring them back to life via MAME.

These arcade machines were among the first available with fully-3D environments, but compared to offerings from other companies are curiously underpowered, even for the time. They include only a single digital signal processor which is tasked with calculating all of the scene geometry while competing machines would use multiple DSP chips to do the same job. As a result the resolution and frame rate are very low. Nonetheless, [Mog] set out to get it working in MAME.

To accomplish this task, [Mog] turned to a set of development tools provided to developers for Konami in the early 90s which would emulate the system on the PCs of the time. It surprisingly still worked on Windows 10 with minor tweaking, and with some other tools provided over the decades of others working on MAME these old Konami machines have some new life with this emulator support.

Not everything works perfectly, but [Mog] reports that most of the bugs and other issues were recently worked out or are being actively worked on by other experts in the field. If you remember these games from the arcade era of the 80s and early 90s, it might be time to grab an old CRT and fire this one up again.
