Yes — but with an important caveat: the stock CosmicWatch v2 firmware was not originally designed to reliably do full SD logging and OLED display updates “in parallel” without trade-offs,…
Right — this is the bit that trips most people up, but it’s straightforward. CH340 is not a “USB drive”. It’s the USB-to-serial chip driver your Arduino Nano clone uses…
# NonOfficial-StuffForCosmicWatchMuonDetectors Extra code and stuff I (Jotham Gates) have made/adapted for Spencer Axiani’s Cosmic Watch Desktop Muon Detector V2 The official website can be found at (http://www.cosmicwatch.lns.mit.edu/) The official…
What format does Arduino use for SD cards? Arduino (including CosmicWatch-style data loggers) doesn’t define its own SD format — it relies on the SD card being formatted in a…
I have accessed Jotham Gates Githib site – how do I now load his firmware onto my Cosmic Watch v2 muon detector? Good — if you’ve already reached Jotham Gates’…
At 1420 MHz (the hydrogen line), the lowest system noise temperature an amateur can realistically achieve depends on the quality of the antenna, feed, low-noise amplifier (LNA), and how much…
For a 1.2 m prime-focus parabolic dish, the beamwidth depends mainly on the operating frequency (or wavelength), not strongly on the F/D ratio. A typical prime-focus dish has an F/D…
With a 1 m dish, observing astronomical masers is challenging but not impossible if you use a low-noise receiver and target the strongest sources. The most practical maser lines are:…
The Norsat 9000LD series is a professional Ka-band DRO LNB used for satellite communications rather than consumer satellite TV. Norsat still lists the 9000L series as a current product. I…
To add three logarithms with the same base: log(a) + log(b) + log(c) = log(abc) Example: log10(2) + log10(3) + log10(5) = log10(2 * 3 * 5) = log10(30) If…
