Unboxing #25: Unboxing the EEVblog BM2257 Multimeter | Learning Electronics In The Lab With Jay Jay

In this video we unbox the Brymen EEVblog BM2257 Digital Multimeter which arrived recently from my mate Dave Jones of EEVblog fame. Thanks Dave!
In the video I mention about the Multimeter Fuse Pack available at the EEVblog Store (but out of stock), but I don’t think that particular fuse pack has the fuses I need for the BM2257. I have asked about what fuses to get on the EEVblog Forum: Appropriate fuses for EEVblog BM2257 Multimeter.
The BM2257 came with Zinc–carbon batteries which I haven’t seen before. You learn something new every day!
There will be a demo video coming out soon to go with this unboxing video, just like I did for my Fluke 17B+ Digital Multimeter:
I am very happy to have my new BM2257. Thanks again Dave. <3

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.

Touch Buzzer | Project 19/20 | Maxitronix 20in1 | Learning Electronics In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video over here.
You can support this channel on Patreon: patreon.com/JohnElliotV
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 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!
