13 posts held, back to 1 June 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 3 pagesof Telegram’s post history, 20 posts per page.
ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.
Measured directly from 4 videos with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.
474 reactions across 13 posts, in 11 distinct kinds. The most used accounts for 34.2% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 13 of the 13 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 474reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 13 most recent posts we hold, published 1 June 2026 to 5 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

وضعیت تولید و قیمت چیپهای حافظه چه از نوع RAM چه eMMC بقدری بحرانی و عجیب غریبه که یکی از بزرگترین تامینکنندههای قطعات الکترونیکی LCSC بردهای لینوکسی Taishan خودش که بر پایه RK3566 هستند رو بدون این چیپها هم عرضه کرده که قیمت مناسبی داشته باشن. اختلاف قیمت بین نسخه بدون حافظه و با حافظه حدودا ۴۸ دلاره. به ترتیب ۱۹ و ۶۷ دلار. در نتیجه شما باید خودتون بعد از خرید دست به کار بشید و این چیپها رو از روی زبالههای ا…

شرکت OpenTools اخیراً پروژهای به اسم OpenPrinter معرفی کرده که عملاً یه پرینتر کاملاً اوپنسورس و تعمیرپذیره و هدفش حذف انحصار و هزینههای مسخره قطعات مصرفی پرینترهای تجاریه. معماری سختافزاری این پرینتر دو تا بخش داره. برد اصلی یه Raspberry Pi Zero Wعه که با یه پلتفرم CUPS بوت میشه و مثل یه سرور چاپ محلی، درخواستهای شبکه رو از طریق وایفای، بلوتوث یا پورت USB هندل میکنه. بخش دوم یه برد درایور مبتنی بر میکروکنتر…

یه یوتوبر به اسم Bitluni یه پروژه باحال و پرخرج استارت زده و یه GPU یا کلاستر دستساز با ۸۱۹۲ تا پردازنده RISC-V ساخته. ایده اصلیش این بوده که برای هر پیکسل یه میکروکنترلر اختصاص بده تا عملاً بتونه خروجی رزولوشن QVGA بگیره، که تو این فاز تونسته بخشی از این معماری عظیم رو پیادهسازی کنه. معماری این بردها که بهشون Blade میگه، روی چیپهای به شدت ارزون ۱۳ سنتی CH570 از شرکت WCH بنا شده. این میکروها روی ۱۰۰ مگاهرتز کلا…

یه طراح الکترونیک یه کارتریدر microSD با رابط USB 3.0 که قابلیت سوییچ کردن کارت حافظه داره رو برای SBCها ساخته. هدف اصلی طراح، ساخت سختافزاری بوده که بتونه بهصورت خودکار و از طریق دستورات نرمافزاری، ایمیجهای سیستمعامل رو روی رزبریپای لود و تست کنه. اکثر طرحهای موجود برای این کار از استاندارد قدیمی و کند USB 2.0 استفاده میکنن، اما این برد از کنترلر GL3224 استفاده میکنه تا سرعت انتقال دیتا رو به ۱۰۰ مگابایت …

معمولاً برای کپچر کردن تصویر نمایشگرهای کوچک LCD که تو پروژههای امبدد با رابط SPI یا I2C کار میکنن، به ابزارهای دیباگ گرونقیمت و دردسر دیکود کردن دیتا نیاز دارید. ولی خب یه توسعهدهنده ابزاری به اسم LcdTap توسعه داده که دستورات کنترلر LCD رو مستقیماً میخونه، تصویر رو بازسازی میکنه و فریمبافر رو به صورت یک سیگنال DVI-D خروجی میده. این ابزار بر پایه بردهای ارزونی مثل Raspberry Pi Pico 2 توسعه داده شده که تو بازا…

شرکت چینی Link Micro داره کلونهای ارزونی از ADCهای (مبدلهای آنالوگ به دیجیتال) پرسرعت و گرونقیمت شرکت Analog Devices تولید میکنه که روی LCSC هم به فروش میرسن. برای پارتنامبر قطعات هم دقیقا از اسم چیپ اصلی استفاده میکنن و فقط یه پیشوند LK به اولش اضافه میکنن، اما قیمت رو به یکدهم نمونه اوریجینال کاهش دادن. احتمالا فشار تحریمهای آمریکا باعث شده این چیپها رو در ابتدا برای تامین نیاز داخلی مهندسی معکوس و تولید…

Showing the 12 most recent of 13 posts we hold for @openpcb. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Citation-graph rank — 498,561 of 1,160,990entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Named by 4 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
Names
Channels on the register whose handles appear in this channel's posts.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 10 August 2026 — this entry's latest reading, not the date you are reading this.
