#DosWeek. I'm making some mad progress with my OPL3 FM synthesis program. Here's a video showing a step sequencer and you can modify the timbre in real-time. I'm taking my inspiration from Teenage Engineering Pocket Operators. Here, I've created a MIDI note to Block/FNUM table to properly set the FM frequency, for real notes. Currently, the app can switch between four patterns that are randomly set up at the beginning of the program.
Let's hang out and talk about nerdy things. Linux. Retro computers. Old video games. Alternative OS's. Stuff that makes us smile. You can join the chat and ask questions.
Well that didn't work well! lol! My data connection took a nose dive! I'll get it sorted and we'll tru this again tomorrow. :)
A casual "May the Fourth" live video
How I described this interview back when I first released it in 2019:
“I get to hang out with the papa of Nerdcore, MC Frontalot, to talk about his new album, Net Split, his break-up album (sorta) with the Internet. We then talk about 300 baud modems on C64's and other things that prove how old we are. In other news: I love my job.”
Worth noting: I still love my job.

Went to my dad's house and picked up some more stuff. (A lot more. But y'all probably don't care about most of it.)
On the left, my Tandy monitor from my 1000. Now, if I can only find the keyboard.
On the right, the SVGA monitor we upgraded to when we upgraded to a 486x66 DX2. I really wish I could find that computer
This is really astonishing to me that both of these survived. My parents had a flood back in 2010 and I thought all of this was in the basement. But my dad found these, and a few more monitors, stacked up in my brother's closet. I have to go back tomorrow for the remaining monitors.
Just ordered these boards. This is my proof-of-concept for resistive touch-sensitive buttons on a PCB, like that thing @Sohl found on Hackaday.
Mostly what I'm doing is torturing the board house here:
My prediction is that all the individual buttons will work (except the two-half-circle one), the LED on L1 will work but not L2, the small buttons will be too small to press just one, and the matrix will work but ghosting will be a problem.
Just got the email that the fab accepted my ...
Should I be excited about RISC-V?
RISC-V based products are starting to hit the market, as reported by the Lunduke Journal and others. Certainly any new instruction set is a little exciting, and the open licensing might be nice for manufacturers who won't have to pay ARM's fees anymore. But I'm not sure that openness will trickle down to people like me. I'm not going to build my own chip factory any time soon. I'm going to buy chips like the Allwinner D1, which seem as proprietary as ever. And just like their ARM-based cousins, they require operating systems to ship nonstandard bootloader blobs in order to run.
As a consumer, if my favorite Chinese SoC vendor offers an ARM chip and a similarly specced RISC-V chip, is there a good reason to pick the RISC-V one? Or does it boil down to marginal licensing cost-savings and minor performance benefits?

The rules around here are super simple:
1) Be Excellent to Each Other.
2) No cursin' or posting material you couldn't show on prime-time TV in the 1980's.
That's it, really! Be cool and keep it clean so folks can enjoy this at work and around their kids.
Oh, and nerdiness is encouraged. The nerdier the better.
