« Didactic Bench » by Kevin KENTZA ZANA is a laboratory equipment realized locally throughout the mastery of microcontroller programming and electronics. It is made of the following devices inside a single bloc: Low frequency Generator, oscilloscope, ohmmeter, voltmeter, capacitance meter, frequency meter, ammeter. This equipment allows to realize more than 80 per cents of electricity, electronics and electrotechnics practical works in general and technical high school and higher education. It is also used in research laboratories. It’s transportable as a laptop and it costs approximatively 250 000 FCFA. In the market, at the moment, laboratories can’t acquire all the mentioned devices with less than 1 000 000 FCFA. Then their acquisition as separated components needs a large space in laboratories.

« Special Signal Generator » by Ulrich SIMO DOMGUIA and Raoul THEPI SIEWE: Designed and realized locally, it uses physics and dynamic systems laws to generate conventional electrical signals ( sinusoidal, square, triangular) but also more complex signals as impulsions with bell shape, impulsions with sticks shape, chaotic signals. These signals result from the mastery of electronics and microcontroller programming. There are signals used in practical works and in research, telecommunications and in biomedical engineering.

« Solar tracker » by Hyacinthe TCHAKOUNTÉ: It is a device responsible for automatically orienting the photovoltaic plates to the optimum incidence of the sun’s rays in order to optimize the production of photovoltaic electrical energy. But it has an acquisition card that records the various data from the photovoltaic plate ( sunshine, temperature, humidity, electrical voltage, electrical current, electrical power and even wind speed). This gives it the character of useful equipment for research on photovoltaic panels.

«Locally manufactured optical bench » by TALLA Alain : The locally manufactured optical bench is a didactic tool that allows practical work in geometric optics to be carried out ( Descartes’ laws, focometry and lenses, the deviation of light by a prism). The designers designed the corresponding optical instruments and had them manufactured locally using the expertise of glaziers.

Local bread oven based on scientific laws : In order to contribute effectively to the reduction of famine in the sub-region while preserving our environment, M. Kouemou Cedric and his supervisors have designed, realized and scientifically studied a new model of bread oven using bio-coal, and a solar-powered, microcontroller- controlled blower. Unlike existing ovens on the local market, the oven prototype produced has safety, ecological and economic advantages. Baking tests have been carried out ( especially on Kumba bread) and the results obtained are in line with the requirements of bakeries in terms of quality and quantity.
