I used to run another site and these were popular. I know they are not related to yaqin but I still get requests for them so here they are:

Pronouncing Yaqin

Dan Ashby — Tue, 30 Mar 2010 12:34:25 +0000

A good multi-lingual friend of mine showed me that pronouncing Yaqin is easy. The only bit you need to remember is that a q in pinyin (the romanisation system for mandarin) is pronounced like a ch with the tongue flat, as in cheese as opposed to bent tongue as in Charlie.

Thanks, Andy.

Server upgrade

I’ve upgraded the server that this site runs from. It is now a P4 2.8 HT – it used to be an Athlon 2600XP. I’ve also tripled the RAM to 1.5GB. I’d love more bandwidth but I can’t afford it – sorry.

Higher quality MC-100B schematic is here

Dan Ashby — Wed, 10 Mar 2010 09:20:11 +0000

The previous schematic was a little tough to read. This one is much clearer thanks to Trevor Lowe.

Yaqin Tube Valve facebook group

Dan Ashby — Tue, 05 Jan 2010 15:50:44 +0000

I thought I’d make a Yaqin facebook group to see if it turned out to be a better place for discussion etc. Facebook allows uploading of images and a more casual interface than my website. Please join up and see how it works out. Ultimately it will only be any good if people use it.

Site back up and running

Dan Ashby — Sun, 15 Nov 2009 22:50:27 +0000

Dear visitors, after a downtime of about five months, I’m glad to say the site is now back up. This was an unavoidable result of difficult personal circumstances. All I can say now is welcome back.
