2024-03-15 Ferranti Argus “Hearing Aid” Computer
In the “Original Series” chapter this very interesting Wikipedia article talks about the “hearing aid computer” that used the OC-71 germanium transistors which were used in hearing aids and could go only up to 25kHz clock rate. That was quite slow – tube computers could clock at 500kHz. Later models used faster transistors and could

This is going to be greatly reducing the need for herbicides – weed killers, which are poisonous, not good for our food. Making for a better, greener world. ▶️ Watch this reelhttps://www.facebook.com/reel/3353248441633569?mibextid=zAoTV8&s=yWDuG2&fs=e
2023-12-07 Laser Weed Killer, Scarecrow, Bug Killer
These autonomous laser devices can be working in the fields around the clock. They could severely reduce the need for herbicides (weed killer chemicals), and insecticides which are also harmful to good insects and other animals and pollute the environment. It’s highly unlikely that a weed will become resistant to a Laser! They can be
