Silly Job Title: Switch Switcher. I am the Switch Switcher!
In this video we do the 19th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Radio Station.
We use the LiteVNA 64 Vector Network Analyzer to measure reactance and resistance of our antenna coil.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signal.
We use the METCAL PS-900 Soldering Station to make our cable fixture.
We use the AiXun H314 Hot Air Gun to shrink our heat shrink.
We use the MUIN Solder Fume Extractor to clear the air.
We use the Riden RD6006 Bench Power Supply to provide power.
We use the EEVblog BM2257 Digital Multimeter to measure resistance and check continuity.
We use the Peak Electronic Design Atlas LCR45 LCR Meter to measure capacitance.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to cut, cut, cut.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Plugerinerer. I am the Plugerinerer!
In this video we continue working through Learning the Art of Electronics. Today we build the circuit from Fig-2N.5 which is a simple RC circuit that we charge with a voltage source.
Our charge and discharge curves for the 1000 µF capacitor looked like this:
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signal.
We use the Riden RD6006 Bench Power Supply to provide 10 V for testing.
We use the EEVblog BM2257 Digital Multimeter for continuity testing the switch we use on the breadboard.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Circuit Breaker. I am the Circuit Breaker!
In this video we continue working through Learning the Art of Electronics. Today we build the circuit from Fig-2N.4 which is a manually switched constant current ramp.
The constant current sources we’re using are these: LT3092 Adjustable Precision Current Source Module, 200mA / 500mA Adjustable Constant Current Source Module, LED Driver.
The other constant current sources I have but that we aren’t using today are these: LT3092 Adjustable Constant Current Source Module 200mA Continuous Adjustable Constant Current Output, Sensor Drive Power Supply.
The box I put everything is the 82x52x35mm-Black box from here: 70/100mm DIY Electrical Enclosure Box Electronic Project Case White Black Grey Instrument Storage Junction Controller Box.
The spanners I mention that I purchased recently are these: 3mm Ultra-thin Open Box Dual-purpose Wrench Set 6-24mm Stainless Steel Spanner Metric Ratcheting Combination Wrench Kit with Bag (6-24mm 12pcs kit).
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate Vout.
We use the METCAL PS-900 Soldering Station for soldering.
We use the AiXun H314 Hot Air Gun for heat shrink.
We use the MUIN Solder Fume Extractor to clear the air.
We use the Yizhan Digital Microscope for close ups.
We use two Riden RD6006 Bench Power Supplies to provide positive and negative power.
We use the EEVblog BM2257 Digital Multimeter for continuity testing.
We use the Brother P-Touch D210 Label Maker for labeling.
We use the nmsafety Nitrile Gloves for hand protection.
We use the ENGINEER PA-09 or PA-21 Crimping Tool for crimping.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
