Vietnam is a counter-example with quite effective bicycle troops. Their army and insurgency was supplied with bicycles on the Ho Chi Minh trail.

I don’t believe the machine gun is intended to be fired while on the move. You’d have to be grabbing that grip at your crotch, aiming without the sights, all the while peddling and steering. That’s quite the tall order. Even under ambush conditions you’d want to get out of the area ASAP, something a bicycle would do better at than on foot.

My presumption is this is intended to be a fast and light machine gun placement. Speedy deployment and movement of machine gun nets without needing to carry all that weight, let along carrying a machine gun’s diet of ammunition, on your back is quite an advantage. Dismounting to get behind the gun isn’t a high bar nor particularly slow. I’m sure a soldier could be sending lead downrange in a matter of seconds. Essentially the same role as light infantry support vehicles today.

The recoil wouldn’t be that bad. Apparently the M1895 was loaded with 6mm Lee Navy at around 2,200J muzzle velocity and a cyclic fire of 450/min. That’s quite manageable. In comparison, the M249 is a shoulder mounted gun of 1,800J, 850/min. That’s 50% more recoil to manage without a bicycle frame to support the firearm.

When cars are the only way to get to a bar or a friend’s place, then you’re going to get drunk drivers. Car dependency has a big hand in causing these deaths.

You’re probably decoding noise or in the middle of the bit stream.

What you’re looking for is called “preamble.” That’s a sequence of bits used to synchronize the decoder (marks the start of data, useful in modulation schemes for clock recovery, and a few other things).

Looking at minimodem’s manual, try using the sync-byte option. Prepend your tar stream with a string of bytes, like 0x01, before sending to minimodem for encoding. Then use the sync code option to mark the start of the tar bit stream. This is as simple as cat preamble.bin myfiles.tar | minimodem --tx …

Other things to consider: start small with 300 baud BFSK before speeding up. Test with wav files before attempting physical tape or speakers and a microphone.

Shooting up or down is hard and takes extra work to understand the ballistics of such a shot.

If you’re really curious, check out Ted’s HoldOver video on the topic. He shows both the theory and practice it takes to shoot upwards.

Not a problem. In that case you’d also have theft charges and would be liable for the car’s value in civil court (or whatever the Danish equivalent is).
