Roman MeliškaYou’ve heard it here before Harvard Business Review noticed: <a href="https://mastodon.social/@asymco" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@asymco</a> & Judd diving deep into iPhone disrupting surgery navigation.

Aaro KoskinenThis <a href="https://bitwoods.duckdns.org/tags/ePaper" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ePaper</a> seems to have 7 internal LUT sets for different temperatures. At 20'C refresh takes 4 secs. By fixing temp sensor to > 50'C, refresh takes 3.5 secs and there's no difference in picture.I copied this "fast" table and started reducing iterations and frame counts so that picture quality still remains intact.I've now reached < 1 s refresh, even for the full 648x480 and it still looks very nice. And now it's fast enough for simple <a href="https://bitwoods.duckdns.org/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> terminal use!<a href="https://bitwoods.duckdns.org/tags/DIY" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DIY</a> <a href="https://bitwoods.duckdns.org/tags/Computing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Computing</a> <a href="https://bitwoods.duckdns.org/tags/LowEnd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LowEnd</a>

Aaro KoskinenLittle progress today but still: Dumped the OTP table data from e-paper which helped a lot. In read direction, these things lack MISO pin so <a href="https://bitwoods.duckdns.org/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> spidev can't read anything but I was able to do it with GPIO bit-bang from userspace.So I have a copy of LUT data and I'm now able to modify and re-load it back to device. There's a baseline and method for the optimization.A crucial document is UC8179 doc that documents the OTP data.<a href="https://bitwoods.duckdns.org/tags/ReverseEngineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ReverseEngineering</a> <a href="https://bitwoods.duckdns.org/tags/SaturdayNight" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SaturdayNight</a> <a href="https://bitwoods.duckdns.org/tags/Hobby" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Hobby</a> <a href="https://bitwoods.duckdns.org/tags/LowEnd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LowEnd</a> <a href="https://bitwoods.duckdns.org/tags/Computing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Computing</a>

Aaro KoskinenThis week's <a href="https://bitwoods.duckdns.org/tags/ePaper" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ePaper</a> <a href="https://bitwoods.duckdns.org/tags/hacking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hacking</a> status: Got partial updates working nicely (pixel-wise) on 15€ unbranded 5.83" WFT0583CZ61. It's just as slow as full refresh, but limits flickering to the updated area, like a single 8x16 char, so the other part of the screen remains readable during refresh.Now I try to make custom LUTs to make it faster. Nice; all registers are documented but no mention about operation principle whatsoever. Typical trial-and-error <a href="https://bitwoods.duckdns.org/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> driver programming.<a href="https://bitwoods.duckdns.org/tags/LowEnd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LowEnd</a> <a href="https://bitwoods.duckdns.org/tags/Computing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Computing</a>

Aaro KoskinenHeh, I've never been an artsy-fartsy graphics guy but I just now recalled how typewriters and matrix printers implemented bold text with 1 color back in the day - just rewind back and type harder!So I tried the similar with my e-ink display. Just go back and redraw a bold character with 1 pixel offset - and you get a nice readable bold text!I consider this a major personal achievement of the week.<a href="https://bitwoods.duckdns.org/tags/Computing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Computing</a> <a href="https://bitwoods.duckdns.org/tags/LowEnd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LowEnd</a> <a href="https://bitwoods.duckdns.org/tags/TextMode" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TextMode</a> <a href="https://bitwoods.duckdns.org/tags/Monochrome" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Monochrome</a> <a href="https://bitwoods.duckdns.org/tags/ASCII" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ASCII</a> <a href="https://bitwoods.duckdns.org/tags/Guthenberg" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Guthenberg</a>

Aaro KoskinenTesting a cheap 6" <a href="https://bitwoods.duckdns.org/tags/epaper" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#epaper</a> display with 80x25 <a href="https://bitwoods.duckdns.org/tags/VGA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#VGA</a> font (sorry for crappy pic due to light & cabling restrictions).I've never seen this tech in real life before, and it's simply amazing! Text is better than on many of the paperbacks I have.I want to simulate <a href="https://bitwoods.duckdns.org/tags/IBM_PC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IBM_PC</a> <a href="https://bitwoods.duckdns.org/tags/MDA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MDA</a>, and thought 1 color bit is OK but forgot about the attributes. 8x16 font on 640x480 has room for the underline attribute (last 5 lines in the pic). But what about "bright", maybe a dotted line?<a href="https://bitwoods.duckdns.org/tags/LowEnd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LowEnd</a> <a href="https://bitwoods.duckdns.org/tags/Computing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Computing</a> <a href="https://bitwoods.duckdns.org/tags/TextMode" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TextMode</a>

Aaro KoskinenMy old 8086 machines are showing some aging symptoms so building some new bare-metal machines for <a href="https://bitwoods.duckdns.org/tags/DOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DOS</a> hacking.Found a TR2350 board from Ebay for 10€. Designed for fanless operation and takes around 5W, just perfect! Although still very overkill for with 128MB RAM (maybe I could get a smaller SO-DIMM). It's based on AMD Geode.Didn't get it to boot over USB - then I dd'ed my emulators image to CompactFlash card and tried IDE boot - worked instantly!<a href="https://bitwoods.duckdns.org/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RetroComputing</a> <a href="https://bitwoods.duckdns.org/tags/PermaComputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PermaComputing</a> <a href="https://bitwoods.duckdns.org/tags/LowEnd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LowEnd</a>
