(usually in conjunction with rotary encoders directly on the motor shafts)<br/><br/>Besides the cost of adding feedback, in the historic 8-bit era of 3d printer controllers there probably wasn&#39;t enough processing power to incorporate and act on the feedback.<br/><br/>Now that 3d printers use speedy and 32-bit microcontrollers (or even, I hear, embed a full linux computer) maybe times can change. 2026-10-23T14:06:48Z https://nostr.now/nevent1qqsz3sq0mpuqlrvwcldkdl8t6hkvyhc0sl0azv6m2a50j7e8wv6c5eqzypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6zx7mn0h In reply to <a href='/nevent1qqsr2jpqk0qryn5mzrfkatt0rjwz9kq4s3qsht7u95p5hlr58l4h4yqnptn92'>nevent1q…tn92</a><br/>_________________________<br/><br/>I&#39;ve been moved to tears by New Horizons pictures of Pluto &amp; even ETH&#39;s &#34;photos&#34; of black holes. Because whether humans were &#34;present&#34; there at Pluto or Sgr A* was immaterial, it still represents for me a triumph of human understanding &amp; undertaking. <br/><br/>What helped me feel this way was a couple of presentations I attended which showed not only the scientific results or the &#34;ooh look at this&#34; photos but also just how human the activity was, folks dedicating decades of their work in some cases.<br/><br/>Besides these two talks I&#39;m thinking of, I also had the opportunity to meet a guy who worked on some of the scientific instruments of Cassini. A humble machinist but clearly brilliant and passionate.<br/><br/>These experiences make me deeply believe that it&#39;s OK if humans never go to the stars or even the planets for themselves; there&#39;s still the work of lifetimes upon lifetimes to learn what we can of the universe remotely. And similarly, to be at peace with the fact that while some future technology might enable it, it won&#39;t happen in my lifetime. 2026-10-13T21:38:56Z https://nostr.now/nevent1qqstm7qufgfs3jxllk0583ngydvxzutqtygcrwe38g8urtkeaet5frczypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6z4z3ev4 so I&#39;m looking to replace digitalocean for the reasons, but it appears I can move the web serving back in the house (I didn&#39;t have gigabit with static ip when I gave up on self-hosting X years ago) .. so it appears that all I need is competent DNS with an API that is supported by one of the major letsencrypt (ACME) clients. number of domains &lt;10, monthly budget under $10USD. suggestions solicited, boosts welcome<br/><br/>not interested in self-hosting dns again.<br/><br/>#askfedi #lazyfedi 2026-09-14T01:08:13Z https://nostr.now/nevent1qqsvrz25lekh9eqw4fqw2ppwwkpa9ucafp9kqvh3k0yzdhjfrzmfnpqzypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6z20mdye <span itemprop="mentions" itemscope itemtype="https://schema.org/Person"><a itemprop="url" href="/npub18g0d4j2g7k6zll4jkr4clkp6vuurlyakdsrs2f4fv0ywnqfmjhuqm00a9e" class="bg-lavender dark:prose:text-neutral-50 dark:text-neutral-50 dark:bg-garnet px-1"><span>Cat Hicks</span> (<span class="italic">npub18g0…0a9e</span>)</a></span> &#39;s book just mentioned at carol willing&#39;s #pyOhio keynote &#34;single best book I read in the last 5 years&#34;<br/> <img src="https://social.afront.org/system/media_attachments/files/116/982/521/590/506/646/original/e7704497eb5248e7.jpg"> <br/> 2026-07-25T20:34:40Z https://nostr.now/nevent1qqsv756uty2l5e9cl8e7ms4002ke34rxazezf3ew2g40pl4x3f34f4czypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6zdxjx2u In reply to <a href='/nevent1qqspe03uytzxzkw94p2fmwkhlf9m9js60d0elknxf864srgtpkwanhgr8td36'>nevent1q…td36</a><br/>_________________________<br/><br/>I tried [FFShare](<a href="https://f-droid.org/en/packages/com.caydey.ffshare/">https://f-droid.org/en/packages/com.caydey.ffshare/</a> ) but had trouble getting it to work consistently.

A couple of thoughts from someone who is fascinated with musical tuning but in a fairly superficial way.<br/><br/>First, in looking at the hexagonal grid pages about 2/3 of the way through I wondered: You touch on scales with more than 12 tones, but only in the guise of equal temperament (29-TET). Would it be possible instead to develop a family of &#34;just&#34; intonations with 29 tones? Would it be described by a similar kind of grid, just with more elements, or would the shape be different?<br/><br/>Second, I went looking in OEIS for the list of &#34;best approximation to 3/2&#34; and found <a href="https://oeis.org/search?q=5%2c7%2c12%2c29%20id:A060528">https://oeis.org/search?q=5%2c7%2c12%2c29%20id:A060528</a> -- but it goes 1,2,**3**,5,7,12,29,... and I can&#39;t figure out what difference between the two statements of the problem leads to 3 being/not being on the frontier of best approximations.<br/><br/>Finally, just an observation: It&#39;s unusual to see a discussion of tuning without an appeal to the overtone series somewhere. I assume this was a conscious decision. 2025-12-25T01:18:04Z https://nostr.now/nevent1qqsqrnln936zym47cwv33erj979q3a3wvpvy6yag8rhrjmknur35zlczypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6zk2z0l6 In reply to <a href='/nevent1qqstm5n2trp4zwdd5r4nk742s3kl96s3yedluxk7fss2kvvewxstcfqq4p87p'>nevent1q…p87p</a><br/>_________________________<br/><br/>wacky takis 2025-12-24T23:30:37Z https://nostr.now/nevent1qqspvjddutf4us7ym6lsdhxhmlgr5m7qemjzpj86pz9rshpryfhp7cqzypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6z0a4y3a I know this is a weird request but if you know of any queer-themed barbershop songs that I can buy sheet music to, please send them my way in the next 24 hours<br/><br/>#vocalMusic #barbershopQuartet #TTBB #queer #lazyFedi 2025-12-15T14:39:40Z https://nostr.now/nevent1qqsw2azlm9ev8n8ghhzj27tgye5we32wwc9k2ejtn6muh6eumyy89tszypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6zdjn4l0 In reply to <a href='/nevent1qqszpltk2e8jpqv05w4tuy5asrn0v84hvpnspwjs8nmesn95434lfpgtgwkh7'>nevent1q…wkh7</a><br/>_________________________<br/><br/>I&#39;ve tried &amp; failed to write a commandline program to upload to a codeberg repo via the /contents/ API...

Previous discoveries of TNOs with extremely wide and elongated orbits suggest an apparent clustering in the longitude of perihelia ϖ≈60∘, motivating the idea that an undetected planet may be shepherding the extreme TNOs. However, with ϖ = 306∘, the orbit of 2017 OF201 is an outlier of that clustering (Figure 2) and likely unstable to gravitational influence from this hypothesized planet. Our N-body simulations suggest that the presence of the Planet X / Planet 9 that produces the clustering will cause ejection of 2017 OF201 in a short timescale around 0.1 Gyr (Figure 4). Nevertheless, more investigation is required to decisively rule out that hypothesis. 2025-05-23T08:51:48Z https://nostr.now/nevent1qqsqqljf78rge9esvzptj938t0yyxh3glk4ysr99p3glr535mv4w6pczypv42zpu527dad7xhe5atvctuvvmv88rzsmkd37ryjwplu5rnwl6zlut9mw more pico-mac stuffs on adafruit fruit jam with rp2350<br/><br/>left: 512x342 resolution on 640x480 framebuffer with hstx<br/><br/>right: 4MB mac emulated with psram (video reversed &#34;because of reasons&#34;)<br/><br/>sadly, placing the main mac RAM in psram slows emulation down considerably.
