trying to track chang'e 5 with some online websites 2020-087A = NORAD 47097 = Chang'e 5 s/c find TLE from satcat on celestrak celestrak n2yo   btw, these 2 websites are mainly for earth bound (geo-centric) satellites. So when chang'e 5 is moving away from earth, they are less accurate asof 26 Nov, Chang'e 5 is already 362,461 km from earth  all in all, for Chang'e 5 and similar interplanetary spacecrafts, it is much better to follow twitter from Scott Tilley , Cees Bassa , Daniel Estevez ,  UHF Satcom , J McDowell or r00t heavens-above weibo: China航天 空天逐夢 9ifly cascwx casaclep zgjw_81 others: sixth tone TLE faq: Celelstrak: how to convert TLE to some other formats

- go to projectpluto website, pseudo MPEC for recent added objects. find the lines which contain Change'5. you will find Chang'e 5(2020-87a) and Chang'e 5 booster (2020-87a) - click the link which has name Chang'e 5   ( 20087a in this case)  - manually copy the MPC data under astrometry section - goto to online find_orb page, and paste the data, and click "Compute orbit and ephemeridis" button   if everything is done as it should, you will the generated output as below   - click "Orbit Simulator View" button here you are, and have fun: or just simply click  this link

 arecibo       Single radio elements have limited spatial resolution (the diffraction limit of the telescope).  This diffraction limited resolution is proportional to wavelength (as it is also for optical telescopes, but it seems more extreme for radio telescopes due to the huge range of wavelengths over which they are typically used).  The diffraction limit for a circular aperture of diameter D is q ~ 1.22 l/D, where q is the angular diameter of the Airy Disk at the half-power point (the full-width-half-maximum, or FWHM) in radians.  At a frequency of 5 GHz, even the Arecibo dish has an angular resolution of only about 50 arcseconds.  The fully-steerable GBT has a resolution at this frequency of only 150 arcseconds.     Because of the limited spatial resolution of single element telescopes, sophisticated techniques have been developed to combine single elements into multiple-element arrays, which work together to form a single telescope.  In such arrays, the spatial resolution is dete

 started from kickstarter in 2020, an "smart" fluid bed type coffee roaster     basically the most simple "one touch" mode has 8 settings. If you look at the flavor, it just illustrates the basics of different roast level, from light roast to dark roast. I guess the main difference is the roast time.  comparison with ikawa and sandbox: 首批用家反響: 銀皮收集盒與上蓋無法完全密合 機器下豆盒與機器有間隙, 不密合   銀皮盒烘120克會卡豆子, 有4～10克不等的豆子卡在銀皮盒 有用家建議這樣改:   88g,有12顆應該是 機器本身因素沒有翻攪到 也許是我們在玩家模式時用的風力比較小，而使得側邊有的豆子似乎容易盤旋不太會掉到斜坡下被熱風吹到所致   pros and  cons of fluid bed roasting.  19 Aug 2021 new improved parts zeczec   SR540 SR800 mod

   onstep:   Howard Dutton's smart hand controller github   OnStep is a computerized telescope goto controller, based on Teensy or Arduino control of stepper motors. It supports Equatorial Mounts (GEM, Fork, etc.) as well as Alt-Az mounts (including Dobsonians, and the like.) OnStep was designed, from the beginning, as a more or less general purpose system and provisions were made in the firmware to allow for use on a variety of mounts. stellarjourney thingiverse groups.io trinamic's stallguard and coolstep hoshimiya's coolstep :  faq  https://learn.watterott.com/silentstepstick/faq/

colorlight 5A-75B( 8 HUB75 ports), 5A-75E(16HUB75 ports) based on lattice semi ECP5-25F, used as LED Panel 卡萊特接收卡( meaning LED panel controller), These are known as a "Receiver Card". Its main function is to receive and forward framebuffer data using a proprietary protocol (from a "Sender Card") and send out control signals to LED panels (via shields, like a HUB75 shield). This 5A-75 receiver card has been out for a few years, and getting less popular now. Usually The system consists of 2 parts, one is sending part made up of sending card; and receiving part made up of receiving cards.   There is  2 kinds of control  systems, one is Synchronous control system, the other is asynchronous.  Widely used Synchronous control cards are Linsn(using Spartan 6), Novastar(using Spartan 6), popular asynchronous cards are control Dbstar(using Spartan-6 Altera) and HD. Synchronous card will synchronously display what is shown on your PC to the LED Display you set up. You need to

Cooler mountain temperatures provide a slower growth cycle for the coffee tree which prolongs bean development . This longer maturation process imbues the coffee bean with more complex sugars, yielding deeper and more compelling flavors. Better drainage at high elevations also reduces the amount of water in the fruit resulting in a further concentration of flavors . The soil in which the finest Arabica coffees are grown is extremely fertile and often volcanic. These rich soils surrender hard, dense coffee beans highly prized for their potential to provide exceptional flavor. HKU 永續坊
