Here are some Hobby Scopes that might even be quite professional if you develop them further. They are virtual instruments. Making Scopes with tablets may be much more easy now.
The µSCOPE – A poorman’s oscilloscope
The oscilloscope is still one of the most important measurement tools of the electronic engineer. With the advent of the often very reasonably priced USB scopes, such an instrument is now within reach of every body.
Digital oscilloscope – Build a simple Inexpensive digital oscilloscope. Single channel, about 100 MSPS. RS-232 based.
xoscope is a digital oscilloscope using input from a sound card orEsounD and/or a ProbeScope/osziFOX and will soon support Bitscopehardware. Includes 8 signal displays, variable time scale, math,memory, measurements, and file save/load.
xoscope – digital oscilloscope for Linux
MHZ100Q is a low cost FPGA-based high speed data acquisition system. Version 2 is a standalone board containing 2, 100MHz 8-bit A/D channels, preamp, 7th order elliptical antialiasing filters, and a Xilinx FPGA.
MHZ100Q – Open Source FPGA-based 100MHz A/D
A USB interface is implemented in the FPGA firmware. Power comes from the USB bus. Schematics, VHDL and Verilog source code, and signal capture and display software are available and being posted.
NYC Resistor is a hacker collective with a shared space located in downtown Brooklyn. The NYC Resistor Microcontroller Mailing List is a great place to meet others with the same interest…
NYC Resistor – Hack Build Learn DIY Electronics
“In this hands-on workshop, you’ll learn how to use a soldering iron safely and effectively, and get plenty of practice with both soldering and desoldering techniques. We’ll be soldering up some Game of Life kits – LED tiles that generate nifty animations.”
Intro to Soldering Workshop
Other Classes Examples –
“We’ll learn to program an Arduino and interact with the physical world! This class covers an introduction to Arduino, including how to use light sensors, LEDs, buzzers, and more.”
“Turn almost anything into a musical instrument with Teensy, an inexpensive Arduino-compatible microcontroller. The Teensy 3.2 has a bunch of touch sensors and analog and digital inputs,..”

There are places like your Backyard, outdoors, a village… where your Gadgets will stop working !!!
You will feel suffocated when your Smartphone or Tablet fails to respond to your caring strokes. Your Dupey is perishing due to Undernourishment. All you need is “Electronic Solar Umbrella” which was invented by me delabs on June 1st 2014.
The Red Light is for Data Networking SmartUmbrellas using Advanced Multi-Threaded Infra Red Technology.
SUN – Smart Umbrella Networking
I just invented the SmartUmbrella – My Drone is Rushing to the Patent Office.
(Keep this confidential till my drone returns safely, the beagle boys are using Blimps with Large Magnets to capture Drones.)
These are high tech jigs, fixtures and instrumentation/automation gizmos that bill built. Electrical gizmo builder for the UNLV Physics Dept.
Bill O’Donnell – Tech Gizmo Builder
These projects are advanced and not for a beginner student or newbie hobbyists. These pages are knowledgable and will help students and DIY enthusiasts understand more about Lasers, Precision Temperature Control and stepper motors among other things.
Auto Fill Circuit for Laser Cooling Loop – Ethernet Data Logging
Here is an automation solution with a ethernet usage. The code and diagrams are also there. This is something that covers many aspects of engineering in one project. Try such things out to learn, only after you have mastered the basics.
“The Ethernet connection is based on an XPORT form Lantronics. Basically it lets you use a serial port to send things over Ethernet. A PIC microcontroller with an A/D converter digitizes the pressure, the pressure set point, the high and low pressure alarm points and the supply voltage (since everything is ratio-metric). “
DSO Nano v2 is an Open Source Portable and lightweight Digital Storage Oscilloscop that has a Color display and is designed for basic electronic engineering tasks. Its palm size and handy features make it great for in-field diagnosis, quick measurement, and hobbyist projects. Schematics and source code files are also openly available for re-innovating.
DSO Nano – Digital Storage Oscilloscope
Auto measurement – Useful for quickly exploring signal characteristics. Measurement options include frequency, cycle time, duty cycle, peak voltage, RMS voltage, average voltage and DC voltage. Please note that frequency, cycle time and duty cycle can only be measured while triggering.
Features – Waveform storage and playback, 6 triggering modes, 200Khz Analog Bandwidth, Complete measurement markers and signal characteristics. Built-in Signal Generator too.
User Interface Overview – The screen is broken into a central display area and 3 operation bars around it. The menu on the top provides the most frequently-used adjustments to signal display. The status bar on the bottom provides precise measurement results and monitoring status. Adjust more advanced functions with the column of function icons on the right.
“My hobby has been a present occupation as it is because I liked electronics relatings since I was little. Railroad, anime, comic and TV game as well. As for programming in the hobby, because they are electronic handicraft” – Chan Japan
ELM – Electronic Lives Mfg
Chan has many projects for learning the use of Microcontrollers. even Instruments. You can even study about how to develop a PC Interface for electronic design you made. Then there are pages on Audio and Video Processing. See the LED Lantern and the Capacitance Meter too.
DC Servomotor Controller
This is an experiment on the closed loop DC servomotor control system (SMC). It will able to be used for practical use with/without some modifications.
Desktop Line Following Robot
In lines of the Japanese Tradition of Miniaturization, chan has built a tiny line following robot which can run on the desk, A toy that is one fifth the size of the line following robots, seen these days,
CheapStat: An Open-Source, “Do-It-Yourself” Potentiostat for Analytical and Educational Applications.
CheapStat – DIY Potentiostat
CheapStat, an inexpensive (<$80), open-source (software and hardware), hand-held potentiostat that can be constructed by anyone who is proficient at assembling circuits. This device supports a number of potential waveforms necessary to perform cyclic, square wave, linear sweep and anodic stripping voltammetry.
The device supports cyclic, square wave, linear sweep and stripping voltammetry over the potential range ?990to +990 mV and over frequencies from 1 to 1000 Hz. The device supports a range of environmental, food and drug quality control, and educational applications. The reverse of the circuit board supports a three-line LCD display and a joystick, which is used to select an experiment protocol, change its parameters (frequency, starting voltage, end voltage, scan rate), and initiate the experiment.
DIY Potentiostat – CheapStat – EEMetric
The device’s schematics, parts lists, circuit board layout files, sample experiments, and detailed assembly instructions are available in the supporting information and are released under an open hardware license.
