In a nutshell, inputs are what the system receives, outputs are what the system communicates to us or to another system. So an input can be a microphone, an output can be a speaker. It is not as simple as that (some components are both inputs and...
Seeeduino Nanos are a clone version of the original Arduino Nano. Arduino is a big proponent of Open Source Hardware, and they made many of their designs available for others to use, following certain guidelines. The Seeeduino Nano has a very similar...
To confirm this all works together and start receiving webhook events from Zoom, the webhook endpoint needs to be validated first. To do this without deploying to a live server, use a service like `ngrok` , `zrok` , or something else to provide a secure...
Let us begin by removing both components marked in the picture below. By removing the integrated RGB LED we are saving some precious mA and by upgrading the voltage regulator (next step) we are expanding our battery range by using a better regulator...
Once this step has been done, we can proceed to interconnect the modules as shown in the following schematic: For the cabling, it was helpful to have the chassis already printed so the cable lengths could be better estimated with all modules in place....
Create a custom socket for the X-tal oscillator from some female pinheads.Solder the 74HC14.Solder the optional power supply.Solder the power LED/resistor.Solder the power switch / header.Solder the decoupling capacitors (100 nF) around the chips.Solder...
Screw the 4 M3 stands off into the PCB and secure them with M3 nuts. Next, fix the MDF heater support structure on top of the stand offs. Make sure not to screw it too tight and leave some space for the thermal expansion. After complete, you will see...
After thermal testing seems great, now you can try reflow something. Here I am using a SSOP chip with an adapter PCB to try out my reflow hotplate prototype. The last photo shows the result of reflow after some cleaning.
The L7805CV is a voltage regulator integrated circuit (IC) that is commonly used to provide a stable and fixed output voltage of +5 volts. This component is part of the 78xx series of voltage regulators, where "78" denotes a positive voltage regulator...
The IRF520N is a power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) commonly used in electronic circuits for switching applications. Here are some key points about the IRF520N: Type: The IRF520N is an N-channel MOSFET. In N-channel MOSFETs,...
A relay is an electromechanical device that functions as a switch, using an electromagnet to control the flow of electrical current. Here are some key points about relays: Switching Function: Relays are used to control the opening and closing of electrical...
The HDMI video output port holds the VGA-to-HDMI adapter. The one used in this design is sown in this photo. At the bottom of the photo we can just make out the DC5V connector. This is to power the adapter, as there is no power supplied via the VGA cable....
