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 put a hook on a stick so I can reach stuff that is high on my pegboard.

In this video I mention Ali the Dazzling and the Star Wars Kid. The wood shop channel I enjoy is Workshop Companion.

We use the Deep Hole Long Nib Pen to mark the points for drilling.

We use the Rockwell RD2971 18V Drill Driver Kit Drill for drilling.

We use the Bosch IXO VI Electric Screwdriver to drive in my screws.

My pegboard hooks are these ones: HORUSDY 120-Piece PegBoard Hooks Set, Peg Board Assortment 12 Different Types of Hooks for Garage Organizer Bins Shop Display Hanging.

We use the 14500pa Cordless Hand Held Vacuum to tidy up after ourselves.

We use the Yum Cha 10pc File & Rasp Set Metal File for filing.

We use the Plato Model 170 Wire Cutter for cutting our string.

The KVM I mention toward the end of the video is my AOOCOO 4K@30Hz HDMI USB 2.0 8-Port HDMI KVM.

If you’re interested in HDMI specs there is heaps of info on the Wikipedia HDMI page.

The monitor I mention toward the end of the video is the UPERFECT 15.6″ HDMI LCD. It’s physically small, but high resolution. I stop using this monitor because I was having trouble making it work with my new KVM and my studio workstation ‘verve‘.

The new component drawers I am getting for the new space on my pegboard are these: Jaycar HB6330 33 Drawer Parts Cabinet

In this video we see what has arrived in the mail from AliExpress.

We use the Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer to test our MOSFETs as they arrive.

We use the Brother P-Touch D210 Label Maker to label our component drawers.

We use the Scotch Titanium Scissors to cut open our packaging.

We use the Hakko CHP 3C-SA Precision Tweezers to manipulate our components.

Stuff that arrived included:

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!
