Hi, and welcome to my page where I cover the gadgets I make and sell.  

Updates and random info below.

2019-05-03 You have to go through checkout to get shipping price, I know it sucks.  Batch shipping is 60 NOK, FedEx priority depends on destination but is generally less than 200 NOK.

2019-05-29 Just found out the FedEx option has not been available for some time.  If you don't get the option of International Priority, there may be some issues with your shipping address.  Make sure your phone number is digits only.

Christmas update

 

Happy holidays everyone!  2018 has been interesting, moving to a new web site and getting the Jammafier and tri-sync helper out.  2019 should see the completion and availability of the JVS-PAC2, and hopefully the scaler.

Jammafier

I got parts for 10 units just before the holidays kicked in and should have them ready for shipping early 2019.  Apart from implementing a screen-saver to conserve the life of the OLED, I think this project is mostly done and I'm very happy about the reception and support it has gotten.  The initial inrush of orders has calmed down a bit, but I plan on having this available on a continuous basis - real-life obligations permitting.  I've enabled stock counting in the store, which either shows stock available or units not already sold in an imminent production run.

One big issue with the Jammafier is the time it takes to assemble it, it has a lot of parts that require manual soldering.  I got another 40 Jamma edge connectors, the hardest part to source, and when those are gone I'm done with manual assembly.  If there is still demand, I will look into having it assembled in China.

Retro Scaler A1

I got both the PCB's and parts for a new revision just before the holidays, and have spent a few nights playing wit it.  Acouple of my arcade PCB's are very noisy so in the revision I wanted to try a selectable low-pass-filter (LPF) to see if it would make a big difference - it didn't.  It's an improvement, but not sure if it's worth the added cost.  Firmware is pretty much the same between rev 1.4 and rev 1.3, so I don't have to make a decision right now.  The 240p test suite http://junkerhq.net/xrgb/index.php?title=240p_test_suite, has proven quite useful in exposing some oddities with the ADC I'm using.  All tests look really good, only thing I haven't figured out yet is PAL interlace (625i).

My goal when I set out to make this was to make something as good as or better than the XRGB2 for arcade games, and I'm happy to say that this thing is way better when it comes to image quality.  I hope to have it 'out' in 2019, which is about time - I've been messing with this thing for years.  Apart from a firmware development, the big hurdle is manufacturing cost. I hope revenue from the Jammafier and JVS-PAC2 will contribute to making this a reality.

JVS-PAC2

Sorry for the delay on this one, I do appreciate getting requests for it though.  I will not do manual batches  apart from an initial proto-type testing batch, but rather go straight to having them manufactured in China like the red original JVS-PAC's.  So when it's finally available, it should be available :)  At least that's the plan.  It's based on the code and hardware of the Jammafier, so it should not take too long. Stay tuned..

 

New batch of Jammafiers

Just a short update on things cooking in the lab.  A new batch of Jammafiers is in the works, almost ready to go out - except the audio connectors are still missing, but supposedly in transit.  There are a few units in this batch that are not spoken for, so if you are in need of one - pre-order yours today :)

JVS-PAC 2 features

I've finally gotten around to tinker with the JVS-PAC 2, a lot of the core stuff has been ported over from work on the Jammafier.

Keyboard output with MAME mapping is a no-brainer and default, I always strive for things to 'just work' for 'most cases'. There will be no XBOX360/One, PS4 support as I assume official licenses are out of reach and I'm not in the possession of the crypto stuff Brooks have - I actually have no idea how they pulled it off.

What I'm aiming for with this one is a single firmware that presents itself to the computer as:

  • A Capable keyboard (enough simultaneous button presses for fighting games etc)
  • A Mouse (I got a dynamic golf panel and would very much like to play marble madness on it)
  • Two Joypads

The idea is to have an .ini file on micro-sd and use the OLED/buttons to toggle/set configuration - i.e. to switch from keyboard to joypad without having to re-flash the firmware.

I've gotten some input on making it 'xinput', which I frankly don't completely understand as x-input is an old windows API, these requests also mention the xbox 360 controller and steam..?

Is the challenge at hand to make the JVS-PAC2 work 'out-of-the-box' with steam titles - drop me a message via the contact section if you have any input (pun intended :) ).
