Discussion
Sure, but I believe this topic is well beyond the scope of a practical guide on a DIY signing device.
This topic directly relates to “due to sanctions its difficult to find hardware in rusia”.
Sanctions on hardware exist (in too small amount unfortunately yet, in 9 years) for the reason — it is used in missiles and rockets to kill thousands of Ukrainians on a daily basis.
Mentioning “due to sanctions” without mentioning why they exist in the first place is a manipulation when there is genocide happening right now and sanctions exist right because of this genocide.
This may be well beyond this topic but one can not expect simply celebrating “a rusian guy finding hardware for a cool DIY stuff” until those hardware stops being used for genocide purposes.
Its very unfortunate that its still possible to find ANY western hardware in rusia.
