 Building a DIY mini deep freezer is a more advanced project than a mini fridge, but it can be done with the right components and some patience. The key difference between a mini fridge and a deep freezer is that the deep freezer needs to reach much lower temperatures, which requires better insulation and more effective cooling components. Materials Needed: Insulated Box or Cooler : Use a thick Styrofoam cooler or an insulated box with high R-value for better insulation. Multiple Peltier Modules (Thermoelectric Coolers) : You will need stronger or multiple Peltier modules to achieve lower temperatures. Heatsinks and Fans : Efficient heatsinks with fans are needed to dissipate heat from the Peltier modules. Thermal Paste : To ensure good thermal contact between the Peltier modules and heatsinks. 12V DC Power Supply : Make sure it can handle the power requirements of multiple Peltier modules.

when heart is not functioning correctly , patients requested to use pace maker , what pace maker do what is the mode of action of this device ?

Image
 Article Writing Pace Maker A pacemaker is a medical device used to treat certain heart rhythm disorders, specifically problems related to the heart's electrical system that cause irregular heartbeats (arrhythmias). The primary function of a pacemaker is to monitor the heart's electrical activity and deliver electrical impulses to regulate the heart rate and maintain a normal rhythm. Here's how a pacemaker works and its mode of action: Sensing Heart Rhythm : The pacemaker continuously monitors the electrical activity of the heart using one or more leads (thin insulated wires) that are implanted in the heart muscle or positioned near the heart's chambers. These leads detect the heart's natural electrical signals. Identifying Abnormal Rhythms : If the pacemaker detects an abnormal heart rhythm (such as a slow heart rate, fast heart rate, or irregular rhythm), it triggers the delivery of electrical impulses. Delivering Electrical Impulses : When necessary, the pacemake...
