In this video we do the 20th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Weather Indicator.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to have a look at the two square waves from the astable multivibrators.
We use the UNI-T UTi260B Thermal Imager to investigate the circuit’s heat profile.
We use the Riden RD6006 Bench Power Supply to deliver 9V to power the circuit and to report on its current draw.

In this video we do the 19th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Touch Buzzer.
This circuit uses a Darlington pair to amplify the very weak signal from the touch sensor.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to look at the square wave from the astable multivibrator.
We use the UNI-T UTi260B Thermal Imager to examine the thermal characteristics of the circuit, particularly the 1K resistors getting warm.
We use the Riden RD6006 Bench Power Supply to provide 9V for our circuit and also to measure the current drawn by the circuit in its inactive (11mA) and active (12mA) states.

In this video we do the 18th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Rain Detector.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to see the 1.6 kHz square wave from our astable multivibrator.
We use the UNI-T UTi260B Thermal Imager to watch the thermal effects of the circuit. We see both the 1K resistors in the astable multivibrator get warm, but only the activated side of the bistable multivibrator gets warm.
We use the Fluke 17B+ Digital Multimeter to buzz out the circuit looking for mistakes.
We use the Riden RD6006 Bench Power Supply to provide 9V for our circuit. I make a mistake and connect it the wrong way around to begin with!

Low-Water Indicator | Project 17/20 | Maxitronix 20in1 | In The Lab With Jay Jay

In this video we do the 17th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Low-Water Indicator.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to see the output of the astable multivibrator. In the video I make a mistake and attach the probe to the wrong pins.
We use the METCAL PS-900 Soldering Station to solder the wires I use for the banana plugs I attach to the touch sensor an voice sensor (microphone).
We use the UNI-T UTi260B Thermal Imager to look at the heat profile of the circuit. We see that the low resistances (470Ω and 1KΩ) get the warmest, but the higher resistances (e.g. 10KΩ) are also slightly visible.
We use the Fluke 17B+ Digital Multimeter to check the resistance of the touch sensor.
We use the Peak Electronic Design Atlas LCR45 LCR Meter to measure the resistance of the resistor we use in the LED attachment circuit. This extra circuit allows us to switch out the buzzer for an LED, which makes a lot less racket. The resistor it uses turned out to be 470Ω.
We use the Riden RD6006 Bench Power Supply to provide 9V for our test circuit. Usually I take a current reading to see how much power the circuit draws in its various states, but I forgot!
We use the Horusdy Soldering Station with Hot Air Gun for its hot air gun in order to shrink the heat shrink which we added to the banana plug cables we attached to our sensors.

High-Water Indicator | Project 16/20 | Maxitronix 20in1 | In The Lab With Jay Jay

In this video we do the 16th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: High-Water Indicator.
After we build the circuit we dump the sensor in a glass of water which causes the alarm to trigger. To avoid the obnoxious noise we put an LED in place of the buzzer.
Please be aware: while talking about this circuit I said that the astable multivibrator “flip flops” between states. And that’s kind of true in one sense, but I should be clear than an astable multivibrator is not a “flip flop” circuit. A flip flop circuit is a different type of circuit known as a bistable multivibrator, which is a different kind of thing. In this experiment we use an astable multivibrator to generate a 1.62 kHz square wave which provides our tone, we do not use a flip flop or bistable multivibrator circuit.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to measure and visualize the 1.62 kHz square wave which generates our tone.
We use the UNI-T UTi260B Thermal Imager to investigate the circuit thermals. We see that the 1K resistors in the astable multivibrator generate the most heat.
We use the Fluke 17B+ Digital Multimeter to measure the voltage across Q5. Between about 500 mV and 750 mV is enough voltage to enable the output.
We use the Riden RD6006 Bench Power Supply to deliver the 9V DC required for the project. We use the current measurement from the power supply to see that when the LED is active the circuit draws about 23 mA compared to about 11 mA when the LED is not active.
We use the Horusdy Soldering Station with Hot Air Gun to dry the sensor after it got wet.

Dear Diary
Just wanted to take a happy snap of the lab today. All is flux. All is temporary.
State of the lab
Thought today was snapshot worthy. Here is my lab as it stands at the end of 2023:
And this is what my lab looked like two years ago, when it began:
Progress on lab upgrade
The lab upgrade is going fairly well. I have to say I’m a bit impatient for my ‘verve‘ hardware to arrive. The CPU is here, just waiting for the case, PSU, and RAM. And one of the PCIe adapters.
That bunch of cables on the floor is roughly where ‘verve’ will go when it gets here and has been assembled.
