Sadly, only crumbling felt inside.

Motivation to fill that void!

picked up the well known electronics textbook - Microelectronics by Millman & Grabel, from my local charity shop, today. Having gone into town to get a copy of "Unknown Pleasures" from HMV. Though not in stock so I downloaded that. Not wholly dissimilar cover art.

https://en.wikipedia.org/wiki/Unknown_Pleasures

Used that edition of Millman and Grabel during my EE degree - overall I think it is quite good.  Smaller than Sedra and Smith because it doesn't seem to hold your hand quite as much and has less content.  The main missing item (for me) is the T model of BJTs, which I find very helpful for back-of-the-envelope calculations.  My copy has the 'normal' cover art; yours is different but is the same as some other international versions of texts by that publisher.  I have a copy of Basic Circuit Theory by Desoer and Kuh that looks exactly the same.

Back in the day (30-35 years ago) I listened to a lot of Joy Division   

Hope you enjoy them both!

Makita die grinder DGD800 with 6mm collet.

collected today - I anticipated that I would need a 1/4-inch collet, which proved correct.

... and the one I got of course wasn't suitable.

On the bright side we make Makita's in the UK. - pity you didn't put a 1/4-inch collet in guys.

But seriously - the premise is that this biggest retail company can supply the right stuff, right?

They just wanna lock you into using only their accessories !
No different to what the A brands have done with various types of active probes for decades.

  Been there still doing that for the one I brought several months ago but IN REVERSE 

In Oz the DGD800 is sold standard with a 1/4" Collet so it suits my nice expensive Sutton Burr set (on the right)

Decided to buy one of the cheapy sets off evilbay for a bit more variety and lower care factor for under 20% of the cost. Sold as a 1/4" shanks but Noooo sure enough they are 6mm  and I have no collet to suit. So off to evilbay to buy a 6mm one, real deal ex UK is stupid expensive so I order a 'Makita' compatible one - FAIL  along with a 1/4 x 1/8" reducing sleeve so I can fit in Dremel sized bits.

So more a case of taking into account 'local' Metric/Imperial issues than a conspiracy it seems. Still need a 6mm collet when I feel the need to search again.

For others playing along at home the Real 1/4" Collet is on the Right the obviously wrong diameter one is on the left.

6mm Collet part # 763670-3
1/4" Collet part # 763673-7

[armandine2]

The 763673-7 collet is proving difficult to locate.

Reminds me a bit of my venerable Ofrex stapler, also made in England, that has unobtainable staples.

Might be my Google Foo is in form but MakitaUK show it as a part at least also a source in Estonia on evilbay eBay auction: #193715786164. I was getting hits in the UK for the 6mm one from the UK.

Good luck with the search

A reminder for those of us in the Colonies... it's the week after "Piss off, King George!" day, so now's the time to fill up your freezer on discount meats to grill for the rest of the summer.

My current "On The Bench Today" project is a economical set of LA probes for the LeSiglent T3DSO2012 scope I bought a few days ago.

I have a copy of eevblog member TK's Siglent LA adapter PCB on the way because the layout lends itself to my intended means of attacking the problem: solder a piece of socket header on the edge of the PCB and just plug the HP pod directly onto it as for my hobbyist use, I don't expect to need more than the 16-18" those whip leads already provide.

Okay, also because the BOM is: $15. Boom! Seeya! Done!    I figured it was something I could just throw a little money at and hopefully it works as well as it did for him; otherwise, I either get the braided cable he recommends and try it that way, or I get a few copies of oz2cpu's Siglent LA Adapter PCB made up and build that with the same pod.

   https://www.ebay.com/itm/294846434318

I've shopped around and seen the HP LA pods going for ~$20-25 with a few grabbits; but since TK's PCB was so reasonable, I splurged $35 on this HP pod which appears to be NOS and in unused condition, with all the whip leads and a full set of HP grabbits.

We'll see how it works out.

I just scored a Keithley 2306 battery simulator from the ebays.  Advertised as "powers up, no display".

https://download.tek.com/manual/2306-901-01%20(F%20-%20Apr%202008)(Ins).pdf

Dave did a teardown of the one channel model here: https://www.eevblog.com/forum/blog/eevblog-1005-keithley-2302-battery-simulator-teardown/


If anyone has one of these (or a 2302) and can measure some power supply rail voltages to help the repair effort, let me know here:

UGGGHHH! *makes sign of the cross*

Gawddamn AliEx link from non-English-speaking sub-site! If you click that link, it will infect all your AliEx cookies so you cannot get back to the English-speaking site until you delete all your AliEx cookies.

Other than that, good clips.

[PlainName]

Quick fix for that (once you're back to normal) is to allow cookies and log into the right Aliexpress, then switch to greylist the site. Greylisting dumps the cookies after a session, but the pre-greylisting cookies will always be there so you get the benefit of always starting with the same setup, normal ops during that session, and any strangeness going away when you shut the browser.

Good to see someone concerned about protecting their new scope.
