“Cubesat in a Box” – design development as of 15 June 2026
Admin
So far, the design has developed as far as the use of an UKRAA PicoMuon muon detector and a power bank providing many hours of 5V power and ability to…
Ultimate speed power bank with compressor UPK 10 H5 from Lidl Supermarket, UK
15 June 2026: Purchased Lidl Ultimate speed power bank with compressor UPK 10 H5. Provides 5V and 12V outputs. Tests at LRO have shown the power bank remains switched on…
What are attachments for power banks that keep them always on called? I need an always on power bank to power my UKRAA PicoMuon muon detector during my trans-atlantic airflight of month for my altitude muon detection experiment
They’re usually called “keep-alive loads” or “dummy loads” (less commonly “load resistors”). In practice you’ll see them sold under a few more consumer-friendly names: What they do Most power banks…
Is there version software for stand-alone cosmicwatch v2 muon detector which allows data to be recorded on sd card at same time as displaying data on screen?
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,…
Installing CH340 driver for Cosmic Watch Muon Detector v2
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…
Jotham Gates’ firmware (file called MuonDetector.ino) for CosmicWatch v2 muon detectors from https://jgohyeah.github.io/electronics/2019/08/12/cosmic-watch-muon.html – allows both screen to display data and data to be saved to SD card when in use
# 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…
SD Card format required by Arduino Nano
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…
Failed attempts to upload revised firmware onto Cosmic Watch v2 muon detector
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’…
What lowest noise level in temperature an amateur radio astronomer at 1420 MHz achieve?
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…
What is beamwidth of 1.2m prime focus satellite dish with typical F/D ratio?
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…
