A little Bluetooth nuggle for my headphones. I was just going to buy some wireless headphones but they seem to waver between cheap and likely shit and ouchingly expensive. I lose headphones at a rate of about once a month which could promise to be an expensive habit very quickly and I'm happy with £30ish Sennheiser earbuds (I buy a couple of pairs at a time, may as well be prepared). Plus, if the batteries die, I can plug them directly into the damn phone.

And it is little. I'm not sure what was in the small car-sized Logitech box that used to pipe Blueteeth into my stereogram.

Lenovo idea pad 330s 14" with i5 8th gen, 8gb ram and 500ish gb ssd. Ips screen fhd. Might be overpriced despite the claimed £250 knocked off full price. Wanted new so paid the money for it.

Not sure if Amazon links work, the catchily named 'Mpow Bluetooth 5.0 Receiver, New Bluetooth Receiver for Car, On/Off Switch,16-Hour Wireless Music, 66ft/20m Range, Hands-free Call, Ultra-thin Portable Bluetooth Aux Adapter for Audio Stereo Earphone'

There's a bazillion of them. Tested it briefly, does what it says. And a lot cheaper than new headphones that I'll undoubtedly lose or somehow terminally yank the wires out of.

I had to buy a 7mm thick 2.5 inch hard disk (lovely mix of units, they should take a lesson from car tyre sizes) in spite of the fact that I have a bunch of 9mm thick 2.5 inch hard drives. Admittedly the new hard disk has more capacity than the combined capacity of the 45 mm tall stack of 5 - 10 year old 9mm disks, and cost less than  any that I bought as stand-alone units.

It's for a new Dell Inspiron that has 256 GB of SSD as standard, and has space for spinning rust as well.

I have two new 1TB SSDs, and have had fun naming them ‘Fruit Shortcake’ and ‘Jammie Dodger’.

By-the-by, it works but sounds a bit shit* which may be a case of you get what you pay for, it ain't a £160 pair of earbuds. Probably fine for a noisy train.

*seems to over-amp and distort a little. Ironically the bluetooth box that used to plug into my stereo did the opposite, it was so quiet you had to turn the stereo up to 35 (eleven is so passé) otherwise it was like being serenaded by mice.

It's fine, it's not for hi-fi porpoises. It worked straight out of the box  :thumbsup: I wanted it for my Creative mp3 player which is fairly underpowered anyway.

A new MacBook Pro with touch bar - 13" i5 quad core, 16GB RAM, 512GB SSD.

Replaces my venerable mid 2011 MacBook Air which is still going strong but an update to my audio recording interface and software requires multi-core cpu & more RAM. I was pretty blase about buying this (just another laptop) until it arrived today. I'm bowled over - smaller & lighter than the outgoing macbook air, faster than my main quad core 2013 i7 iMac, gorgeous screen, touch ID login just works, sound is better than adequate. Yes it was very spendy but if it lasts as well as the outgoing macbook air it'll be worth it.

As mentioned, the evil geniuses (well, one called Vivian) at the Apple store made me buy a pair of new iPhones. I felt a bit bad at handing her my very grungy iPhone 6, which in the surgically clean retail splendour of the Apple Store looked a little worse for wear. I could only apologize greatly. I'm surprised she didn't get out a pair of latex gloves to touch it. Even my wife backed away a step. We'd only gone in to ask about a battery replacement so I wasn't planning on exposing it (it's been in a silicone case since forever, and all the grunge had levered its way behind it – and yes, I'm talking about the phone). On the plus side, it hid all the dinks and scratches.

But anyway, nice though it is, bigly! Sat on my desk next to my mothership-issued iPhone SE. I don't have pockets big enough to hold a dinner tray.

I'm not 100% sure that this can be described as 'computing stuff', but it's certainly related.  It comes under various descriptions, but one of the most common designations is LCR-TC1, and it's variously referred to as a Multi-Function Tester or Transistor Tester.  I just got it, although I ordered it a few days ago.

 

If you plug any small electronic component into it, it will determine what it is, and give you the basic parameters for it.  It seems to be able to identify single cell batteries (no more than 4.5V), capacitors, resistors, inductors, diodes, zeners, bog-standard bipolar transistors, thyristors, triacs, JFETs, MOSFETs and IGBTs.

You can probably buy similar unit, without a case or battery, and with a B&W screen for as low as £7 from China, and if you're willing to wait you can get this one with an internal USB charged Lithium cell and case probably for £12 on Banggood, AliExpress of eBay.  On eBay, I paid £15 with about 1 week delivery to Argos Click'and'Collect).  Now I know what to search for, they are also available for £18 on Amazon, with Prime next day delivery!

It's not terribly accurate, especially with some of the slightly more exotic parameters, like a capacitor's ESR, but certainly provides approximate values.  If you want to measure a zener, with a reverse voltage greater than 4.5V, there's a pair of special connections for that, which will supposedly work up to 30V, although it failed to measure a 29V Zener in a YouTube video I saw (but did work with a 20V Zener).

I've tested it on a few random capacitors and resistors, and it generally gives a value within the quoted error range of the components, and happily identified a MOSFET, although it measured an RDS variously between 0.2Ω and 0.4Ω, when the datasheet says a typical value of 0.065Ω and maximum of 0.075Ω.  However, for a unit costing £15, I didn't expect a great deal of fidelity!  Internally it's relying almost entirely on an AVR microcontroller for the measurements, and the ADC on that is optimistically only 10 bits typically over 5V, so naively that's resolution of 5mV, but I suspect other factors affect its ability to measure some parameters.

Quite a cool, neat little gadget. :thumbsup: :)
Actually, it is rocket science.

I've got an older variation on that theme.  I really like the ZIF socket for bunging random components in, and it's replaced my cheap Chinese LCR meter for quickly identifying random resistors without reliable colour vision.  One of my favourite functions is being able to read the ROM address from DS18B20 temperature sensors, for ease of identification or hard-coding in embedded things where a discovery algorithm would take up too much space.



Looks like yours has a much better case design, particularly with regard to accessing the lever on the ZIF socket.  I keep not getting round to trimming the plastic on mine so it's a bit less fiddly to release if you fully depress it.

It's also got basic frequency and voltage measurement, a basic frequency generator, and (more usefully, since I don't have something better that will readily do it) the ability to generate a PWM signal at arbitrary duty cycle.  Mine doesn't have the zener feature - it just identifies them as normal diodes.  Given how handy I've found the 15V diode range[1] on the 121GW multimeter, that sounds well worth having.

A lot of functionality in a cheap little gadget.  At a price that's well worth it for anyone starting out in electronics (I expect the actual *testing* of components is a lot more useful if you're not so confident about what you're doing, particularly when it comes to troubleshooting circuits), and useful simply as a random component identifier for tidying up after breadboard sessions.  The precision isn't brilliant, but it's perfectly sufficient for "what is this?" and "has this lost its magic smoke?".


[1] A niche multimeter feature that really shouldn't be:  Extremely useful for testing series LEDs, as well as zeners.

A Logitech G203 mouse. It is a 'gaming' mouse - I'm not going to use it for much gaming, but seems a reasonable quality option for a wired mouse. It has a button to adjust the DPI, if you want a hypersensitive high-speed cursor. And it has built in multicoloured lights8)

A bluetooth dongle for my thin client pc that gets used as a media server. It is going to become my zwift computer too, now that zwift bluetooth seems to work properly on windows 10.
