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.
