IKALOGIC WS200 and SQ200

In today’s mailbag I received a box containing an IKALOGIC WS200 hand held scope and an SQ200 logic analyser.

SQ200 and WS200 unitsThese French-made units are oscilloscope and logic analyser respectively and they arrived in attractive packaging, directly from IKALOGIC in Limoges, France. Translations to English are spot-on, if only some others used the same care.

The packaging as it turns out was not only attractive but functional as the box arrived without any of the usual marks or dents.

To use these units it is necessary to visit  the IKALOGIC web site to grab the software which  is available for Windows/Mac/Linux/Android/IOS

First off, the WS200. I can honestly say, given my current recovery status, I was worried in case setup proved difficult, but my fears proved unfounded. These small units are easily set up (at least on a PC).

tmp90A7 The scope software installed without issue which allowed me to have an initial play by connecting the supplied micro-USB/USB lead.

As the WIFI connection is used for data, USB for power, you initially need the Ikascope to use its own internal access point and set your device to work with this access point, however once that is done you can tell Ikascope from that point on to use your normal access point if you wish (as I do).

I could however find no way to tell it about my WIFI access point. I contacted support by email and sure enough they pointed me in the right direction. The unit initially sets up its own access point and then can be used by putting your mobile device onto that network and once you have done that initially, it can in future be joined to your existing network.


So now, I turn on my Ikascope by merely pressing the probe (ProbeClick) and it immediately connects to my access point.

There’s not much to the above picture simply because there isn’t much to see externally on  the scope. No buttons to press, merely the probe to press (ProbeClick) to initiate a reading on your PC or mobile device on the downloadable “Ikascope” software. Simple. I like it.

The scope comes with the ground lead for the probe head and a USB lead for charging, along with a little setup card.


I’ve tested the unit on both my Windows laptop and Android smartphone. PC software shown above.

Here’s the Android phone screenshot.


Coming up next – a first look at SQ200..

The unit turns on automatically when connected to USB and the PC software has a clean interface. Of course, the software is also available for MAC and Linux, though not, it would seem, mobile Android/IOS devices.


The SQ200 unit has 4 inputs and handles a range of input voltages and supports a good range of protocols out of the box with more online.

Here we see the SQ200 unit running Scanastudio (3.0.14) on my laptop… testing I2c from a BME280 to an ESP8266 on Aidan’s new weather station.



Mustool G600 Microscope from Banggood

Some time ago, Banggood send me a Mustool G600 Microscope. The intended use for this was and is as a visual aid when assembling and testing small electronic boards (that’s what I need it for anyway).

MUSTOOL Microscope from BanggoodThe scope is excellent for this as it is adjustable from just a few mm height above the test object to 130mm or more. Resolution is also adjustable.

The unit has it’s own backlight and display and runs off USB. It also has an internal rechargeable battery and can run for many hours without a connection to USB power.

As it turns out, when the unit  arrived, I was stuck in hospital for some weeks and for some of that time had difficulty reading anything, full stop. The scope proved to be indispensible in helping me to read. It is worth noting that the scope has an SD memory slot and can make (quality) recordings but I’ve no use for that particular feature.

Now, my eyesight is more or less back to normal and I’m starting to look toward commencing board construction and testing again and the Mustool microscope now has earned a spot on my workbench.

Here is the Banggood link for the G600. https://goo.gl/b5EQZ4

More of my Postbag

It could take some time before I’m fully fought up with my various postbags, here is some more:

Yokogawa TY720 True RMS Digital Multimeter

In the last entry I looked at the UNI-T UT61E Digital Multimeter in this entry I’ll talk about the Yokogawa TY720 True RMS Digital Multimeter.

Yokogawa  TY720

The TY720 is a solid unit and could well become my favourite meter. As well as the usual voltage, current and resistance measurements, this rather large, backlit, 5-digit beauty (which has closed-case calibration) has data memory and does diode testing, capacitance,  frequency measurement and more. Measurements can be absolute or relative and you can select min, max, average with auto-hold, data hold and more.

Frequency measurement is from 2Hz to 100Khz and temperature readings  from –200c to 1372c (with optional probe for temperature. I did not receive one of these).

The meter runs on 4 AA cells. Too early at this point to say how long they will last but it is easy to replace the batteries. Construction looks fine and overall appearance is good. At this point I can’t find anything negative to say. Operating temperature at –20c to +55c is outside of anything my unit will encounter.

All in all, a very nice meter.

I also have a very nice Owon meter with Bluetooth but as that is currently in storage, a review will have to wait a little while, meanwhile there is far, far more in the current batch of post that I still need to cover.


First reviews of 2018

Thanks for your continued patience, everyone. Following on from my little mishap in December, which has effectively prevented me from blogging or making YouTube videos from mid-December onward, I plan to start doing some blog writing with more detailed blogs and videos to follow perhaps in April/May when I’ll also have access to all my electronics gear following house moving. Our original plans which included spending the entire summer in Spain, came adrift mid-December.

For now I’m doing my best to respond to your emails and looking to doing some short equipment write-ups. I have some catching up to do on the writing front. At least now I have a computer with camera up and running.

Here is a start on some of the stuff that arrived for me while I was out of action.

UNI-T UT61E 4-digit True RMS Multimeter from Banggood



Being used to run-of-the-mill 3.5 digit multi-meters, the UNI-T UT61E 4 digit True RMS Multimeter represented a move upmarket for me and the unit I received came complete with optically isolated RS232 adaptor. A USB cable is, as an alternative, available as an option on all models in the range except UT61A. I should have thought about that but I didn’t.

  1. Operating temperature range is 0c to 40c with storage range claimed to be –10c to 50c. As well as the usual AC/DC voltage and current measurements with accuracy as high as 0.5%, resistance and diode testing, the UT61E tests capacitance as well as frequency and duty cycle.

The meter comes complete with mini-CD. I did not need to use this.

Measurements can be absolute or relative to readings stored earlier. The unit also has a HOLD button and a PEAK button.

The meter uses a single 9v battery. Banggood supply this and many other measuring instruments. https://goo.gl/c887zA


Welcoming in 2018

Here we are in 2018 and I'm sure it will be another great year for IOT.

It could be a while before I'm back in the driving seat but for those who have been firing in questions about my health, just to let you know that I am still in hospital and am getting physiotherapy with more to come.

Armed with only a mobile phone, creating new content could be a challenge for now but I will do my best to answer comments and even add some short replies.

Thanks to everyone for your support and a special thanks to my beloved wife and good friends for making this a lot less depressing than it would have been otherwise.




Waiting for Peter, closing the 2017

MrShark at the console, while we're all waiting for Peter to come back, let's try to add some new content to the blog 🙂

I've a couple of new boards to test, unfortunately they've to wait I receive their PSUs... material for an other time 🙂

So, I'll add some valuable resources found on the net in recent times, about Node-Red development...

I wish a Happy New Year to Peter and his wife, and to all of you readers... please keep visiting this blog and comment, let's leave some new material for him when he's back 🙂

Why has Peter been so quiet?

I'm posting this entry on behalf of Peter (my name is Jonathan - a long time friend of Peter who he has mentioned a few times in the blog). Peter says:
"Unfortunately last Friday (December 15th) I was taken ill and find myself in hospital. While I am making a slow but steady recovery, it will be a few weeks before I am well enough to continue my adventures in electronics, but In the meantime I hope to have a few guest posts and will be keeping up with any conversations as best I can. Jonathan will post some updates on my health and my friend MrShark will try and help with any technical queries. Please do keep an eye on the blog and I look forward to resuming normal service as soon as I am able.

ESP8266 Mesh Experiment

MeshIn case anyone else (like me) has been sitting on the shelf over this one – and would like to have a go at an ESP8266 mesh… we’ve been having a play.

Regular readers may recall I wasted the better part of a year with those AWFUL NRG24L01 boards trying to make a mesh and ultimately getting no-where – indeed I think it is the mere existence of that board that drove me to the ESP8266.

Fast forward to December 2017 - take 3 ESP8266 modules, run the same code on each of the three, attach a LED+resistor to GPIO12… take ESP8266 modules for a walk. One is in the house, one in the office out of range, the other in the middle sitting on my car in the freezing cold.   When all 3 are talking to each other you’ll see 3 flashes in quick succession…

Christmas RGB Animation

Cloe admiring my Christmas lights

My ESP8266 home control code contains not only RGB code for serial LEDs but also a complete programming setup to generate and loop sequences… and so with merely one wire and VERY  little work, we end up with some fancy animation.

Here we see an old, gutted plastic Christmas window decoration which WAS filled with old fashioned white lights but now has a string of 69 serial LEDs running animation around the inside.

I made one of these last year but when it came to trying out my animated LED Christmas lighting this year – nothing happened – dead. After wasting hours I remembered I’d changed the code earlier this year so for anyone using my ESP8266 software and wanting to knock up a quick Christmas animation – here it is…

Odrvm 4K Action Camera

Slightly out of the normal, I’ll grant you but I thought this was worth doing a short piece on because of an alternative use for this camera. So what we have here is the Odrvm 4K Action Camera, which comes as a complete kit, in my case from Amazon.

ODVRM Action Camera as WebcamHere’s the story. I’ve been looking for one of these for ages for Spain, I have a decent camera, an SLR which would be wonderful were it not for the weight. Despite a lifetime dabbling in photography, I’ve never gotten used to carrying around a large camera in the hot summers of Spain which is where I plan to be this summer.

I can’t tell you how many hours I spend trawling through videos on YouTube for an “action camera” capable of at least 2k video and preferably with a gyro to minimise shaking.

Simba on OdrvmWell I was just down to the last couple of cameras when I received an email from a company who wanted to know if I would check out their action camera! Next thing I knew I was off ordering a camera and spare batteries on Amazon PRIME for next day delivery and this morning, my parcel arrived – well, part of it. Not unusually for Amazon, there was a last minute hitch and the batteries won’t be here until next week.

However as it turns out the camera package comes with all sorts of mounts (I mean LOTS of mounts), the camera itself contains a battery and.. there’s a spare one in the box! The manufacturers claim 80 minute battery life but if we assume that means somewhat under an hour of video’ing, it makes sense to have a spare or two.

Odrvm 4K Action Camera

As you can see from the above, action is limited to no closer than maybe 6-9” – but beyond that is extremely sharp – this is shown in the video.

So, as requested I opened the box, described what was inside then went off into the freezing cold Bellingham winter air to take a video.

And that’s fine, no-one is suggesting using this as a top end video camera but with anti-shake it is pretty good for the money – however – that’s not all because it ALSO makes a very good webcam – better I may add than Logitech upmarket models I’ve tested.  So – when you’re not out taking mountain photos – this doubles up as a webcam while it is sitting charging – sounds like a good idea to me.

I did enquire and the sound level is fixed in the unit. Right now it is not possible to add an external microphone, this will likely change in future (if I were to do any serious filming I think I would record audio on a phone with proper external mic – I’ve yet to come across a camera built-in mic that is very good.
