How Much Water Is Too Much?
I think maybe I’ve been drinking too much water. Gonna try to cut back to 2L per day.
Arduino project
I’m trying to debug some Arduino code with my mate Aleksei, but I really need my new scope (which hasn’t arrived yet) so I can see what’s actually going on. I might circle back to this in the near future.

EEVblog #168 – How To Set Up An Electronics Lab
This was good fun: EEVblog #168 – How To Set Up An Electronics Lab. I think I ticked most of the boxes, but it did give me an idea of a few things I’m missing. But not for long! :)
Resistance is futile
I was chatting with my mate CK about my resistor inventory. I’ve got two sets of shelves dedicated to resistors, and a folder with 50 resistors of pretty much every type possible at 1/4 watt and 1% precision.
Diagnosing non-functional RD6006W
So I have a Geekcreit® XH-M229 Desktop Computer Chassis Power Supply Module ATX Transfer Board Power Output Terminal Module which I’ve plugged into an old ATX power supply. I’m using that to power a RD RD6006 RD6006W USB WiFi DC DC Voltage current Step-down bench Power Supply module buck adjustable converter multimeter 60V 6A. When I assembled my RD6006W and powered it up, “nothing happened”. I wasn’t sure where the fault was, but I used my new OWON XDM1041 Digital Multimeter and my TENMA 72-10505 Bench Power Supply to narrow down the problem: I’ve blown the fuse for the 12 volt line on my ATX power supply. So gonna replace that soon. In the mean time I’ve been testing my RD6006W by powering it off the 5 volt line. So far so good.
ANENG AN-999S Desktop Multimeter
So I got myself a new toy from AliExpress: ANENG AN-999S Desktop Voice Multimeter Professional Digital Bluetooth 19999 Counts True RMS Auto Range DC/AC Meter (I got the ‘AN999S 4’ option with batteries and extras). It’s just a bench multimeter, but it has some cool features which make it a welcome addition to my workstation, which is that it has a built-in clock and thermomiter, and if you press the button on the COM lead it will speak the reading for you, which is pretty cool, and I guess means you don’t have to look away from the circuit to get your reading. Look forward to playing with this one, definitely a happy customer so far.
Rigol Scopes
So I watched this talk about setting up a home electronics lab in which the presenter recommended Rigol scopes as being a good budget brand for entry-level hobbyists (like me!). I did some research and collated some data and put together this report on Rigol scopes. As mentioned in the report in the end I settled on an MSO5074. I’m a prosumer, baby!
