I was in the beginning of my Amateur Radio "life" sputnik and OSCAR-1 were thrilling. Today, still an active Ham, I have my satellite antennas ready for ARISSat-1. Sounded great on the test, looking forward to some QSOs and pictures. Hat's off to the ARISSat Team, well done. de WF6J
1961 i was 5 years boy playing toys. Oscar 1 in the space in 1962 ! Those days all popular with vacumtubes triode,tetrode,pentode. Solid state was rare.Those instruments in the picture all heavy and rock solid.real strong design and fabrication work!
ARISSat-1 is scheduled to be deployed from the International Space Station (ISS) this Wednesday August 3rd (Morning in the US). The extra-vehicular activity (EVA) schedule is (all times UTC):
1430 : Hatch Open
1446 : Egress ARISSat-1 and secure to airlock ladder
1452 : Remove ARISSat-1 solar panel covers
1507 : Translate to deploy site, activate ARISSat-1 PWR, TIMER1 and TIMER2 switches, verify LEDs on, and deploy
The deployment will be broadcast on NASA TV - http://www.nasa.gov/multimedia/nasatv/index.html

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
