This DIY oscilloscope project is powered by a STM32 processor and the details of its design are shared by Vitorbnc on Instructables. As an oscilloscope, it displays signal waveform, voltage magnitude, frequency, and duty cycle. Besides, it also features capabilities to measure inductance, temperature and pressure.

GreatScottLab‘s new project video is about making a DIY soldering station using Arduino and a standard JBC soldering iron. The video also provides all the basic info you would need to know about soldering station, including thermocouples, AC power control and zero point detection.

Parking in your home garage could be a bit of challenge if you have a bigger vehicle. You would like to make sure when you parked, you had enough space to walk around the vehicle. This Instructable describes an Arduino based garage parking assistant that would allow you to park in your best spot every time.
It uses an ultrasonic transducer to measure the distance between your car’s bumper and the backside wall of the garage. A control box with visual indicators using bright Green and Red LEDs signals you when you are on the exact spot. Prior to its first use, you need to calibrate the sensor by parking your car in the best position that you like.
Jesus Echavarria from Spain has tipped us off about his latest experimenting circuit board. This time he has made a testing circuit board for Adafruit’s FONA808 module that carries SIMCOM manufacturer’s SIM808 GSM and GPS transceivers.
The Adafruit board includes this module and also some electronics for choosing voltage levels, battery connection and charger. Because I need to test and programming some of this modules, I decide to make an specific PCB for it, allowing the programming and debugging via PC, wich is more comfortable that use a microcontroller for all these tasks. I use the MCP2221 USB-Serial bridge and add some electronics to give the board more functionality. So it has a connection for a 3.7Li-Ion battery, battery charger, manual pushbutton to turn on/off the module and also several led’s to indicate the status of the different elements and network connections. So, let’s go for it!
Becky Stern’s new Instructables describes how to build a very simple realtime YouTube subscriber counter using a ESP8266 board and a seven segment LED display module.
I was inspired by the Play Button awards YouTube sends out for subscriber milestones and whipped up a simple circuit using an ESP8266 wifi board and seven segment display to show off my realtime subscriber count. This is a great IoT beginner project, with just a little soldering and a code personalization required to make it work for your own account.
Before attempting this project, you should be generally familiar with uploading new programs to your Arduino board and installing code libraries, both of which you can learn for free in my Arduino Class, though you really don’t have to understand any of the actual Arduino code to get this project running.
