I live in fear that if I die my wife will sell my retro stuff for what I said I paid for it. #-o

I have evtech which was the eevblog recommended budget meter, think it was more than £8 though!

Edit: and think he may have persuaded me to get a Siglent to replace my rigol.

It is a glorious time to be involved in such things. Uploaded the Gerbers at midnight on Saturday and received the PCBs at 3.45pm today (Friday).

Also, I order the components from Digi-Key in the US at 11pm on Wednesday and received them at 9am today (i.e. only 34 hours later). :D

Now to get soldering and see if it works.

Oooh, go on, flash your boards ;) - I'm assuming you went DHL? :D

Yes.

The boards were a little over 100 x 100 so I ended up paying $13.66 for 5 boards. DHL was $25.02.

This a very rough proof of concept for something I have had at the back of my mind for about a year. There are a whole host of reasons why it won't work. So I want to try it out before posting any details.

First glance at the boards suggest quality may be a little better than those I have used before.

Everyone seems to have swapped to jlc recently. On the home brew sites you see people giving away dozens of boards where they have ordered a couple they needed. I picked up 4 of 5 different boards for free recently because of jlc :)

They're quick and ridiculously cheap. It's cheaper (and less grotty) than trying to etch your own by a country mile. If you keep the value of boards below £14 you don't end up paying any VAT/duty either. You can get a lot of boards for £14.

They’ve done some really clever marketing sponsor all sorts of electronics oriented YouTube channels, including some with pretty low subscriber numbers but where those subscribers are just the right people to target.

Yes smbaker doing RC2014 stuff has quite low subscribers but in the RC2014 world he probably has the most, and RC2014 is all about design, ordering and building boards. So it pretty much means everyone in that small community has gone or is going jlc. And I think most people here have made that conversion as well.

A re-printed copy of the New Advanced User Guide, courtesy of Mark at Retroclinic.

I've not seen this mentioned here, but you can now get this, and the Master Reference manuals in lovely, re-printed binder editions. I already own the original Master Reference manuals, but I'm still tempted to pick up a re-print at some point.

Well, not quite today and not very acorn related but it's main use will be for acorn development/emulation.

A Dell Optiplex 760 usdt with 4Gb of ram and a core2duo e7400 cpu for £10!
I also got a Phillips Brilliance 2218 22" widescreen 1080p monitor. For £10!
£20 for a PC with a decent monitor which also works with my RiscPC is a win in my book.

Much has been said about that desoldering station, all positive.

I have one and have not regretted it.

I think one of the above is better for the job :^o

I still use braid more often than the desolder station.

I'm about to reverse engineer a Victor 9000 hard disk DMA board, it's rare as hen's teeth so whilst I might use braid for cleaning holes out, I'm going to use the right tool for the job on this one! :D

Smaller (partial) surface mount 8-bit IDE podule.
IMG_20180810_220808.jpg
It fits vertically in an A30x0.
IMG_20180810_220541_HDR.jpg
Only one short that stopped it working first time, it was on the first resistor pack I fitted. (I still need to seriously improve my surface mount soldering skills. Never used so much desolder braid whilst assembling a PCB before)

I have one, but it is not easy to get the small filters for the gun; except, I ordered some of th large ones from farnell intending to cut some of them down and they sent me the discontinued (by them) small ones instead :)

Nice work! This is the latest version of your own design, I take it?

Just a small evolution, 374 buffers replaced with 574's to make the layout easier. Swapped the 245's around so I can use R/W signal from podule bus rather than having to invert it, saving a GAL pin. Clock pins for the latches are combined saving me another pin on thr GAL, together that made enough room for a 3 bit page latch for the ROM in the GAL, so removed the seperate page latch chip. Still uses the same ZIDEFS software.
