DocScrutinizer05 | freemangordon: R/2R network on parallel port? how uninspired. I loved the 1bit DAC with like 16fold oversampling directly to the PC beeper more intriguing | 00:55 |
---|---|---|
DocScrutinizer05 | true speech from a single TTL-level output | 00:55 |
freemangordon | DocScrutinizer05: naah, that was too noisy, 8bit DAC was way better :) | 00:57 |
DocScrutinizer05 | nowadays those 1bit DAC are considered the most linear and accurate thing you can find in top notch CD players | 00:57 |
freemangordon | I know | 00:58 |
DocScrutinizer05 | admittedly with 128 or 1024fold oversampling | 00:59 |
freemangordon | iirc the problem was that 8088 was not fast enough to output enough samples per second for good sound | 01:01 |
freemangordon | using speaker IO prots that is | 01:02 |
freemangordon | *port | 01:02 |
DocScrutinizer05 | yep, particularly since that port been (and still is?) hooked up via some weird console ioctrl | 01:03 |
DocScrutinizer05 | iirc | 01:04 |
freemangordon | well, the code was written in ASM (I am talking about DOS days), but still CPU was too slow for anything but a robotic voice | 01:05 |
DocScrutinizer05 | according to wikipedia you'd need 2^(16*2)-fold oversampling for a 16bit accuracy of a 1bit DAC | 01:05 |
freemangordon | while with 8bit DAC on PP it was giving an acceptable quality | 01:06 |
DocScrutinizer05 | :nod: | 01:06 |
DocScrutinizer05 | just kidding basically | 01:06 |
freemangordon | yeah | 01:07 |
DocScrutinizer05 | but tbh I'd not use a R/2R but a logarithmic network | 01:07 |
freemangordon | DocScrutinizer05: actually that's what we used, now I remember | 01:08 |
DocScrutinizer05 | you can achieve 16bit quality witha 12bit-log DAC | 01:08 |
freemangordon | 9 resistors | 01:08 |
freemangordon | 1 with constant resistance and 8 with variable | 01:09 |
DocScrutinizer05 | of course you should encode your samples accordingly then | 01:09 |
freemangordon | DocScrutinizer05: well, I had written a test program counting from 0 to 255 on PP, so nearly linear DAC was achievable by fine-tuning varable resistors | 01:10 |
freemangordon | *variable | 01:11 |
freemangordon | however, I need some sleep | 01:12 |
freemangordon | night | 01:12 |
* DocScrutinizer05 just woke up, finding his fridge as empty as the last 4 days :-/ | 01:13 | |
* DocScrutinizer05 wonders if flu not vanishing is the cause or maybe also the result of this | 01:13 | |
DocScrutinizer05 | increeeedible, a useful SPAM to council ML | 01:17 |
merlin1991 | huh? | 01:27 |
DocScrutinizer05 | council@maemo.org got a unsolicited mail from koon-hongkong - about *phones* | 01:29 |
DocScrutinizer05 | emergency phones though | 01:30 |
DocScrutinizer05 | like for elevators, highway etc | 01:30 |
DocScrutinizer05 | koontech.com | 01:32 |
DocScrutinizer05 | respect for their spamming department | 01:33 |

chem|st | freemangordon: still not able to build modest | 11:42 |
chem|st | after 14th I may have some time, from the stable user point of view there is no "big" reason to hurry, most want the nifty features not included | 11:43 |
chem|st | it was frustrating burning 3 evenings with trying to find out how modest might build | 11:46 |
chem|st | especially after I had it built and was told that it was the wrong version... oh no it was the right one... does not build anymore | 11:47 |
chem|st | I am going to show my sister how to build stuff for fremantle next week, if anyone got a hand with this modest crap it would be much appretiated | 11:49 |

freemangordon | chem|st: I can build modest for you. and AFAIk there is a really wanted feature to be included in CSSU-S - libcurl3, it fixes a couple of things broken by IPv6 | 18:56 |

luf | merlin1991: pong | 22:35 |
merlin1991 | what's your avaiablility on the 13th (thursday)? | 22:35 |
luf | No plans for that night ;) | 22:36 |
merlin1991 | then now you've got plans :D | 22:37 |
luf | I see :) | 22:37 |
freemangordon | merlin1991: confirming that systemui no longer leaks, it sits steady on 1620k, 22 hours uptime | 22:54 |
freemangordon | will continue to check though | 22:54 |
merlin1991 | that's good news :) | 22:55 |
freemangordon | yeah :). I was thinking... is it a good idea to reverse systemui itself and to make it .launch, that could save some memory. not sure how it will behave in act_dead though | 22:56 |
freemangordon | not now of cource :D. but in a month or so, when I am no more disgusted with it ;) | 22:58 |
