Re: TinyLlama (Vortex86EX SBC)

Yes here is the thread where I found the utility Wfflash (attached to first post). I was trying to figure out why my dead GF MX200 PCI worked with the Tiny Llama and no where else. There are some other utilitys that can dump VGA BIOS in DOS as well. https://www.vogons.org/viewtopic.php?f=63&t=91158 …

I bought AST1300 too, and have had the same experience so far. The card often crashes on a resolution above 640x480. In Quake instantly after a couple of milliseconds. Compared with Vortex VGA, it's just slightly faster, about 10%, at least in Quake. Below are measurements taken from Quake (1.06). …

Often the problem isn't the current rating it's the voltage sag. USB cables are often the cause of this - I did a test on a lot of cables a while back and they all performed very differently. Some brand-name ones would drop down to 4v at 500mA... Also a lot of "5v 2A" power supplies will drop down …

About 2A Psu, for my tiny llama, was not enough. In the end, I used 20W PSU. I measured the current draw a while back, don't remember the exact numbers but it was in the ballpark of slightly under 1A. There might be an initial surge though, and of course whatever you plug into the various …

Only the original waveboards need the 12v. All of the newly created ones run on 5v. Here is the simple adapter that was made to just use the gameport for modern waveblaster boards. And that port only has 5V on the pins: https://www.serdashop.com/CHiLLandPhilAdapter so sounds pretty doable, maybe …

Maaaaybe... I'm not familiar with how a waveblaster works, does it basically just process a serial midi signal and send back analog audio? Yep, here's the pinout: https://www.epanorama.net/documents/pc/waveblaster.html BRESET (pin 15 on the CS4237B) would drive the wavetable RESET input. Is that …

Just a quick thought. With the shortage of Raspberry Pi Zero 2 boards (at least here in USA). Would it be possible to make a small adapter to connect a Waveblaster board to the crystal chip for midi tunes? I have a couple waveblaster boards from Serdashop and was thinking how great it would be to …

Throwing out a question regarding heat sink, have heatsink on the chip and remove the "blue" heat sink that it comes with or just putt heat sink on top on the blue one. What could be pros and cons depending the way to go? Underneath the blue 86Duino heat sink/shield, there's a fat thermally …

Eivind as you order from JLCPCB, dont you have any files ready to go, for JLCPCB BOM? ;) would save us some time to put a order ;) Short answer: nope. Long answer: the gerber files are included and will work today, next week and 2 years from now. BOM files however need to be updated about every few …

w00t! I'm going to see about doing a small run (5-25) of these through JLCPCB. Once I get all the stuff uploaded to JLCPCB I can see what the manufacturing cost is and how many I can afford to have done for redistribution in the US ;) I just got the BoM put together in their format, gotta generate …
