Do you have any info you can share on this recorder? Sounds really interesting!

Is it possible to buy the standard version and upgrade to the pro later for the difference between the two pricing tiers ($30)?

Is that a feature of the $20 plan? Or only the $50?

What a great response by Adams! I think the acceptance, and even the celebration of failure is present among the “maker” community in the USA to some extent, which has really drawn me to it.

I wonder if there’s the same outlook on failure among other creatives, would be interesting to compare the hobby communities opinions between the USA and UK.

I’m assuming each image was taken with 123 microamperes? Or is that total dosage over the 21 hours? If it’s total that’s much less than medical dosage, but if it’s per image that’s a lot more!

Thanks for the info, how interesting!

(for those who don’t know, mAs = mA • seconds = milliampere seconds. It’s how Radiographers measure how much x-ray photos are being produced by the tungsten filament in an X-ray tube. kVp is kiloVoltage potential and it’s how we measure the speed and thus the penetration power of the X-rays. 130kvp is slightly more than the 120kvp used for an avg human chest radiograph)

What kVp/mAs do you use for this? How are you avoiding the artifacts seen from medical imaging? Curious, in school for CT in the medical field.
