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.

Silly Job Title: Electronics Guru. I am the Electronics Guru!
In this video we continue to work our way through Learning the Art of Electronics. In this video we return to 1L Lab: DC Circuits and revisit lab 1L.4.3 in which we made a 10 mA ammeter. This time around we do a better job of it, build two ammeters from different movements, and compare our results with an actual known-good ammeter.
As promised here are the notes:
We use the Tenma 72-10505 Bench Power Supply to provide 5 V for testing.
We use the EEVblog BM2257 Digital Multimeter to measure our resistor and as our reference ammeter.
We use the Sharp EL-546L Scientific Calculator to calculate our shunt resistance.
We use the Multicomp Pro MP701033 Resistor Decade Box as our shunt resistor.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Sparky. I am Sparky!
Today is Module Monday and the module we’re looking at today is the HW-390 Soil Moisture Sensor Module. This is a capacitive sensor which is different to the two previous moisture sensors which were resistive.
The code for today’s demo is here: 2026-04-20-HW-390-Capacitive-Soil-Moisture.ino.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to look for a waveform (there was none).
We use the EEVblog BM2257 Digital Multimeter to measure voltage and resistance.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
