VCF East: [Vince Briel] Of Briel Computers

April 7, 2014 by 13 Comments

Replica1

Judging from the consignment area of the Vintage Computer Festival this weekend, there is still a booming market for vintage computers and other ephemera from the dawn of the era of the home computer. Even more interesting are reimaginings of vintage computers using modern parts, as shown by [Vince Briel] and his amazing retrocomputer kits.

[Vince] was at VCF East this weekend showing off a few of his wares. By far the most impressive (read: the most blinkey lights) is his Altair 8800 kit that emulates the genesis of the microcomputer revolution, the Altair. There’s no vintage hardware inside, everything is emulated on an ATmega microcontroller. Still, it’s accurate enough for the discerning retrocomputer aficionado, and has VGA output, a keyboard port, and an SD card slot.

The Replica I is an extremely cut down version of the original Apple, using the original 6502 CPU and 6821 PIA. Everything else on the board is decidedly modern, with a serial to USB controller for input and a Parallax Propeller doing the video. Even with these modern chips, an expansion slot is still there, allowing a serial card or compact flash drive to be connected to the computer.

Video below, with [Vince] showing off all his wares, including his very cool Kim-1 replica.

Multijoy_Retro Connects Your ‘Wayback’ To Your ‘Machine’

Moore’s law is the observation that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every two years. This rapid advancement is certainly great for computing power and the advent of better technology but it does have one drawback; otherwise great working hardware becomes outdated and unusable.  [Dave] likes his flight simulators and his old flight sim equipment. The only problem is that his new-fangled computer doesn’t have DA15 or DE9 inputs to interface with his controllers. Not being one to let something like this get him down, [Dave] set out to build his own microcontroller-based interface module. He calls it the Multijoy_Retro.

3D Printed Camera Arm Saves $143

Professional camera equipment is notoriously expensive, so when [Raster’s] LCD camera arm for his RED ONE Digital Cinema Camera broke, he was dismayed to find out a new one would run him back $150! He decide to take matters into his own hands and make this one instead.

The original arm lasted a good 4 years before finally braking — but unfortunately, it’s not very fixable. Luckily, [Raster] has a 3D printer! The beauty with most camera gear is it’s all 1/4-20 nuts and bolts, making DIY accessories very easy to cobble together. He fired up OpenSCAD and started designing various connector blocks for the 1/4-20 hardware to connect to. His first prototype worked but there was lots of room for improvement for the second iteration.  He’s continued refining it into a more durable arm seen here. For $7 of material — it’s a pretty slick system!

Between making 3D printed digital camera battery adapters,  3D printed camera mounts for aerial photography, affordable steady-cams, or even a fully 3D printed camera… getting a 3D printer if you’re a photography enthusiast seems to make a lot of sense!

 

Hack A Day Goes Retro In A Computer Museum

April 7, 2014 by 17 Comments

vt100_HAD Our friends over at Hack42 in the Netherlands decided to have some fun with their computer museum. So far, they’ve been able to display the Hack a Day retro site on three classic computers — including an Apple Lisa, a DEC GIGI, and a run of the mill DEC VT100. We had the opportunity to visit Hack42 last October during our Hackerspacing in Europe trip — but just as a refresher if you don’t remember, Hack42 is in Arnhem, in the Netherlands — just outside of Germany. The compound was built in 1942 as a German military base, disguised as a bunch of farmhouses. It is now home to Hack42, artist studios, and other random businesses. The neat thing is, its location is still blurred out on Google Maps! Needless to say, their hackerspace has lots of space. Seriously. So much so they have their own computer museum! Which is why they’ve decided to have some fun with them… Continue reading “Hack A Day Goes Retro In A Computer Museum” →

Arduino-Controlled Marquee Arrow Points The Way To Whatever You Like

April 6, 2014 by 28 Comments

Reader [pscmpf] really digs the scrolling light look of old marquee signs and as soon as he saw some Christmas lights with G40 bulbs, he was on his way to creating his own vintage-look marquee arrow.

We must agree that those bulbs really do look like old marquee lights or small vanity globes. [pscmpf] started by building, varnishing, and distressing the wooden box to display the lights and house the electronics. He controls the lights with an Arduino Pro and an SSR controller board. The 24 lights are divided into ten sections; each of these has its own solid-state relay circuit built around an MC3042 as the opto-coupler, with a power supply he made from a scrap transformer.

[pscmpf] shares some but not all of his code as it is pretty long. There are five patterns that each play at three different speeds in addition to a continuous ‘on’ state. In his demonstration video after the jump, he runs through all the patterns using a momentary switch. This hack proves that Arduino-controlled Christmas lights are awesome year-round.

Hackaday Links: April 6, 2014

Back in September we saw this awesomesauce wristwatch. Well, [Zak] is now kitting it up. Learn more about the current version, or order one. [Thanks Petr]

Home automation is from the future, right? Well at [boltzmann138’s] house it’s actually from The Next Generation. His home automation dashboard is based on the LCARS interface; he hit the mark perfectly! Anyone thinking what we’re thinking? This should be entered in the Hackaday Sci-Fi Contest, right? [via Adafruit]

PCB fab can vary greatly depending on board size, number of layers, number of copies, and turn time. PCBShopper will perform a meta-search and let you know what all of your options are. We ran a couple of tests and like what we saw. But we haven’t verified the information is all good so do leave a note about your own experience with the site in the comments below.

We recently mentioned our own woes about acquiring BeagleBone Black boards. It looks like an authorized clone board is poised to enter the market.

Speaking of the BBB, check out this wireless remote wireless sensor hack which [Chirag Nagpal] is interfacing with the BBB.

We haven’t tried to set up any long-range microwave communications systems. Neither has [Kenneth Finnegan] but that didn’t stop him from giving it a whirl. He’s using Nanobridge M5 hardware to help set up a system for a triathlon happening near him.

VCF East: PetPix, Streaming Images To A Commodore PET

PETaday

Thought the Vintage Computer Festival would just be really old computers with hundreds of people pecking 10 PRINT “HELLO” 20 GOTO 10? Yeah, there’s plenty of that, but also some very cool applications of new hardware. [Michael Hill] created PetPix, a video player for the Commodore PET and of course the C64.

PetPix takes any video file – or streaming video off a camera – and converts 8×8 pixel sections of each frame to PETSCII. All the processing is done on a Raspberry Pi and then sent over to the PET for surprisingly fluid video.

There is, of course, a video of PetPix available below. There are also a few more videos from [Michael] going over how PetPix works.
