DSN 나우
DSN Now is the NASA JPL live display of the Deep Space Network, the antenna complexes at Goldstone in California, Madrid in Spain and Canberra in Australia that communicate with spacecraft beyond Earth orbit. The page shows each antenna and the spacecraft it is currently tracking.For each active link it lists the spacecraft name, the […]
블리츠오르퉁
Blitzortung is a community operated lightning detection network that shows lightning strikes on a live map. The map displays strikes as they are detected, with color indicating the age of each strike, and offers views for Europe, North America, Oceania, South America, Asia and Africa as well as for the whole world. Detection is based […]

Windy is a visualization platform for weather data, showing wind, gusts, temperature, pressure, precipitation, clouds, waves and many other layers as animated maps. The interface lets the user select a forecast model, an altitude level and a time step, and also display radar, satellite and lightning layers as observations.Our view: a must, extremely visual and […]
회로에 관한 모든 것 교재
The Textbook section of All About Circuits hosts Lessons in Electric Circuits, a free electronics textbook by Tony R. Kuphaldt. It is organized in volumes on DC circuits, AC circuits, semiconductors, digital circuits and a reference volume. Each volume moves from basic concepts such as voltage, current, resistance and the fundamental circuit laws to network […]

Explained Visually is a set of interactive explanations created by Victor Powell and Lewis Lehe at setosa.io. Each page takes one mathematical or statistical idea and lets the reader change parameters while the visualization updates. Topics include Markov chains, eigenvectors and eigenvalues, principal component analysis, ordinary least squares regression, conditional probability and image kernels. Short […]
IP 주소 블랙리스트 확인
The IP Address Blacklist Check tool on WhatIsMyIP.com serves as a diagnostic gateway for auditing the reputation of a specific IP address against more than 70 DNS-based Blackhole Lists (DNSBL) and Real-time Blackhole Lists (RBL). By cross-referencing an IP against these global databases, the service identifies whether a network identifier has been flagged for activities […]
CivilMath 토목 공학 계산기 디렉토리
CivilMath provides a specialized suite of web-based calculators designed for structural, geotechnical, hydraulic, and transportation engineering analysis. The platform facilitates complex technical computations for beam deflection, truss forces, and section properties, alongside geotechnical modules for assessing soil bearing capacity and lateral earth pressure. It also includes utilities for fluid mechanics, such as pipe flow and […]
BOINC(Berkeley Open Infrastructure for Network Computing) 프로젝트 앱
BOINC (Berkeley Open Infrastructure for Network Computing) is free, open-source software that lets people donate their computer’s spare processing power to scientific research. It was created at UC Berkeley’s Space Sciences Laboratory, originally to run SETI@home, and was released as a general platform in 2002.How it works: You install the BOINC client and choose which […]
NIOSH 리프팅 방정식 계산기
This calculator applies the revised NIOSH lifting equation. Inputs are the horizontal and vertical location of the load, the lift distance, the asymmetry angle, the frequency, the duration and the coupling. The results are a recommended weight limit and a lifting index.The lifting index compares the actual load with the recommended limit, so a task […]
DINED 인체 측정 데이터베이스
DINED is an anthropometric database of body dimensions from Delft University of Technology. It provides measurements such as stature, reach and hand size for several populations, with percentiles, and tools to select the dimensions relevant to a design.Design decisions based on a single average user fail for many people. Percentile data allows designing for a […]
