Fish ‘call’ the Fisherman

pascal
Pascal Katana, a Fourth Year student at the Department of Electrical and Information Engineering at the University of Nairobi, Kenya, developed an electronic device that ‘automates’ fishing. The trap employs amplification of the sound made by fish while feeding. The acoustic signals are radiated and attract other fish who head toward the direction of the source thinking there is food there.
Once a good catch is detected by a net weighing mechanism, it triggers a GPRS/GSM device attatched to the system and the fisherman gets a call/sms informing him that his catch is ready. Pascal is in the process of developing a by-catch control system which will ensure that his contraption doesn’t cause overfishing.

Simon Mwaura’s Mobile Remote Control Inventions

Simon has hardwired a way to open and lock his door remotely via his phone, as well as get tea brewing and other manual and remote tasks. The video speaks for itself, so I’m not going to say anything other than to link you to my past thoughts on challenges for tech entrepreneurs in Africa.
