"I've really improved my programming skills over the years. The original prototype had a lot of spillage and I also had to work on that," he said.
Nkhumise has also worked on timing to make sure that the right steps are done at the correct time. The steps include putting maize meal in the compartment and water in the pot then pressing a button that does the rest of the work including, whisking and turning the pap.
"When I told my mother about my invention she was happy about it. I also had an uncle who only ate pap and his wife said this would have been helpful. So I got a lot of high fives," he chuckled.
Nkhumise, who is working on other inventions under his company Planet Eye, said this invention is relevant even though there is instant pap.
"Instant pap is ultimately not cooked the same way as pap, this is still the same as traditionally made pap," he said.
Nkhumise said he is looking forward to the future and creating new inventions that will take off.
"We want to be the most influential technological company in the world with inventions that are brand-new," he said.
The design is open sourced to the public.
