Introduction: How to Make Electrical Sandglass
Hey, this is the electrical sandglass we want to make, it not shows the time as perfect as a clock,although it is of no actually use for showing time, just for fun, for electronics nerds :).
Step 1: Buy the Pcb and Components
1. We buy some PCBs(here I recommend SysPCB Shenzhen China, fast prototyping service) and components from internet. You can design the PCB by yourself or ask it from PCB layout company, component can source from digikey or mouser or somewhere else.
Step 2: Assemble the Components( IC LEDs and Other Electrical Parts) on PCB
We do the assembly on PCB, some components like LEDs you can solder by your self. For IC, resistor,capacity, better find a an assembly house to do it for quality consideration
Step 3: Assembly Two Main Parts Together
We assembly the two main parts together, they are connected by PCB connector. Simply press them will finish this step.
Step 4: Overview of the Device
we finished the assembly, here is the overview of our electrical sandglass.
Step 5: Enjoy the Fun Please
Plug into the socket, we see the performance, it works great. Wanna try it your self?
We have a be nice policy.
Please be positive and constructive.
