WEEK THREE (2)



Bismillahirrahmanirrahim.

Last week, I managed to buy some components for my circuit. But some are not available and must buy online. I had bought all components of my circuit except for INA126P which I will buy online because of the shop does not have any stock of the IC.
For the circuit, there are a few changes being made. The INA126P pin configuration and details is almost the same with TLV24772. The 280Ω resistor also I change to 270Ω resistor. 2μF capacitor changed to two of 1μF capacitor.
I bought all of these components at we called ‘Jalan Pasar’ near Pudu LRT Station. I went to Nixie Electronics (M) Sdn. Bhd to buy all the components because Nixie has many electronics components available. 



I also am searching electrodes and electrode connectors/leads for my project. For electrodes, a technician at Nixie had suggested me to buy the massage machine which had the electrode itself and also the electrode connectors.  

Barakallah.

WEEK TWO (2)


Bismillahirrahmanirrahim. 

I plan to buy components for my circuit. So, I need to know details for each component. For EOG circuit, I use:
1.  LM7805
2. LM358
3. INA126
4. 9V battery
5. Capacitors
6. Resistors

The figure is the EOG circuit which I use for this project. 

There are a few components I had change due to some difficulties to get it. TLV247XA I change to LM358. The datasheet for   LM7805, LM358, INA126 and TLV247XA is searched and studied. The pin configuration, the supply power and the IC itself is being compared and contrast. 

Barakallah.
