Learning the Art of Electronics: 1W.1 Designing an Ammeter | In The Lab With Jay Jay
You can support this channel on Patreon: patreon.com/JohnElliotV
This post is part of my video blog and you can find more information about this video.
Silly Job Title: Electronics Guy. I am the Electronics Guy!
In this video we continue working our way through Learning the Art of Electronics and begin working through 1W Worked Examples: DC circuits. Particularly we design and implement the 1A ammeter. Next week we will do the voltmeter.
I measure the internal resistances of my various analog meters, which comes out like this:
| Meter | Resistance (Ω) |
|---|---|
| 100 µA | 2,271 |
| 1 mA | 239 |
| 10 mA | 27 |
| 100 mA | 7 |
| 1 A | 2 |
| 5 V | 4,916 |
| 10 V | 9,150 |
| 15 V | 13,010 |
We use the METCAL PS-900 Soldering Station to solder our 222 mΩ resistor.
We use the AiXun H314 Hot Air Gun for the heat shrink.
We use the MUIN Solder Fume Extractor to clear the air.
We use the Riden RD6006 Bench Power Supply to provide test voltages and currents.
We use the EEVblog BM2257 Digital Multimeter to measure various things, particularly resistance.
We use the Sharp EL-546L Scientific Calculator to crunch a few numbers.
We use the Carpenter Mechanical Pencil to make notes.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to trim component leads.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

He runs us through the JFET as amplifier, constant current sink, and variable resistor. He also mentions about the SiC JFET, Silcon Carbie JFETs, which have very low resistance.

Silly Job Title: Current Commander. I am the Current Commander!
In this video we take a look at the IR-08H avoidance sensor module and another similar component. Unfortunately we weren’t able to make them work in the end. :(
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate the signals on the module.

This post is part of my video blog and you can find more information about this video.
Silly Job Title: Electron Ambassador. I am the Electron Ambassador!
In this video we figure out how the power subsystem from the Space Drop circuit works. I’m a little confused in the beginning but by the end I understand how it works. The documentation for the circuit we build is here: JJ005.
We use the METCAL PS-900 Soldering Station for soldering.
We use the AiXun H314 Hot Air Gun for heat shrinking.
We use the MUIN Solder Fume Extractor to clear the air.
We use the EEVblog BM2257 Digital Multimeter for continuity testing.
We use the Brother P-Touch D210 Label Maker to label our JJ005 circuit.
We use the Bysameyee Head-Mounted Magnifier for magnification while soldering.
We use the ElectroCookie PCB Prototype Solderable Breadboard to build our circuit on.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to trim component leads and cut wire.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Current Curator. I am the Current Curator!
In this video we follow the instructions to build the Space Drop handheld computer game which you can buy in kit form from here: Space Drop Solder Kit.
The kit comes with the software preinstalled on the D1 Mini microcontroller, but in this video we replace the code with our own version of the code just to see if we could. And we could! Our code is here: Space_Drop.ino.
We use the METCAL PS-900 Soldering Station for soldering.
We use the Pro’sKit SS-331H Desoldering Pump to remove the OLED screen which I accidentally installed without the spacer.
We use the MUIN Solder Fume Extractor to clear the air.
We use the Bysameyee Head-Mounted Magnifier for magnification.
We use the Scotch Titanium Scissors to chop up the packaging for scrap-booking.
We use the Hakko CHP 3C-SA Precision Tweezers for holding solder off cuts.
We use the Plato Model 170 Wire Cutter to snip off component leads.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

p.s. today I added OLED to my spell check.

Silly Job Title: Maker of Videos. I am the Maker of Videos!
In this video we do the 13th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Leaky Faucet.
Here are the timing measurements we took:
| Capacitor | Resistor | Period |
|---|---|---|
| 10 µF | 470 kΩ | 3.05, 3, 2.97, 3.03, 2.98 |
| 10 µF | 100 kΩ | 0.67, 0.6, 0.8 |
| 100 µF | 100 kΩ | 7.02, 7.02, 7.15 |
| 4.7 µF | 100 kΩ | 0.43, 0.35, 0.39 |
| 4.7 µF | 470 kΩ | 1.76, 1.5, 1.56 |
We use the Rigol MSO5074 Mixed Signal Oscilloscope to look for the oscillating signal.
We use the UNI-T UTi260B Thermal Imager to check the thermals (nothing interesting to report).
We use the Carpenter Mechanical Pencil to take our notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
