Camera stabilizer
In the world of videography and cinematography, visible camera shake is a common thing. Visible camera shake usually is caused by the movement of the camera operator when using a camera. Camera stabilizer is a device used by many people to reduce or remove the visible camera shake to create better quality videos. Most camera stabilizers available in the global market uses advanced technologies that can stabilize a camera very easily. However, the use of advance technologies has caused a spike in the price of these camera stabilizers. There are very little to none option when it comes to a low-cost camera stabilizer available in the market. This project main purpose is to design and fabricate a low-cost camera stabilizer that would be affordable to more people from different walk of life. The low-cost camera stabilizer will use simple mechanism to stabilize a camera instead of advance technologies that are used on most high cost camera stabilizers. The result shows that this low-cost camera stabilizers were able to stabilize a camera and reduce the visible camera shake using the balancing mechanism
Characteristics of BSCF–SDCC–Ag composite cathode powder for low-temperature solid oxide fuel cell
A fuel cell is a type of clean energy that may be utilised in various applications across numerous sectors. Solid
oxide fuel cell (SOFC) has attracted considerable interest as a fuel cell type due to its excellent efficiency and durability.
However, SOFC may encounter specific challenges because of its operating temperature, which is generally high. This
circumstance might negatively affect the overall system performance. New materials that can work with SOFCs in the lowtemperature
range (LT-SOFC) must be introduced to overcome the challenges. The milled barium strontium cobalt ferrite–
samarium-doped ceria carbonate (BSCF-SDCC) composite cathode was introduced as a potential candidate for LT-SOFC
material. Argentum (Ag) was added to the BSCF–SDCC composite cathode to act as a catalyst material for efficient
performance. The characterisation of a BSCF–SDCC–Ag composite cathode was investigated under two properties,
namely, chemical and physical. The X-ray diffraction results for phase identification showed that Ag addition exhibited
compatibility with BSCF–SDCC composite cathode with no occurrence of impurities. The morphology and element
observation showed that the composite cathode powder was well mixed, and all significant elements were uniformly and
homogeneously distributed. The average percentage of porosity value was also obtained in the acceptable range (20%–
40%). Specifically, it ranged from 21.12% to 22.50%. Therefore, the findings of this study prove that the addition of Ag
can improve the performance of the BSCF–SDCC composite cathode, which is in line with the function of Ag as a catalyst

CHARACTERISATION AND AREA-SPECIFIC RESISTANCE ANALYSIS OF BARIUM STRONTIUM COBALT FERRITE - SAMARIUM DOPED CERIA CARBONATE - ARGENTUM FOR SOLID OXIDE FUEL CELLS
One of the most challenging aspects of fuel cell technology is searching for appropriate materials that can address and compensate for solid oxide fuel cell (SOFC) weaknesses. This study focuses on a barium strontium cobalt ferrite-samarium doped ceria carbonate-argentum (BSCF-SDCC-Ag). Some experimental work has been done to investigate the material’s potential use in low-temperature SOFCs. The experimental variables include chemical, physical, and electrochemical characteristics. The phase identification of the composite cathode powder was analysed and showed that all element intensity peaks appear at their respective JCPDS numbers, with no secondary peaks occurring. The morphology and element distribution analysis illustrated micrograph images and the mapping of the material demonstrated that all elements are properly distributed and
mixed. Based on the findings of the porosity and density tests, each sample contained the acceptable range value of porosity between 21.12 % and 22.50 %. The electrochemical
performance was analysed at 400 C, 500 C and 600 C. In comparison to BSCF-SDCC, BSCF-SDCC-Ag 1 wt% had a greater ASR value. The ASR value drops in the BSCF-SDCCAg 3 wt% sample while increasing in the BSCF-SDCC-Ag 5 wt% sample. Apparently, when the temperature is set to high, the ASR value is inconsistent. This might be due to the
symmetrical cell sample condition, since its surface is cracked. Overall, the BSCF-SDCC-Ag 3 % contributes to a decrease in the ASR value at temperatures 400 C and 500 C, but at 600 C has a slight increase in ASR value of approximately 10.4 %. Thus, further exploration of the production technique and preparation procedure is crucial to ensure the cathode reliability and performance for SOFC application
