an enigma indeed...

Heading north on the A1 today, blue sky, blue sea , just out of Berwick we passed a sign , left to Conundrum and then we flashed over into Scotland - makes you think, doesn't it!

My BFE65 is currently seized. The MD65 is fine.
Great little lathe - had mine for about 25 years... so not as long as you...

This gets weirder. Same university, same lecturers, same hall of residence, same knowledge of Southampton, both built unipivot arms at school, both had chassis made at HL ...

I still need to source an adequate connector. Most give an AC rating rather than DC. Is is reasonable to convert an AC rating to give a DC rating? And if so the internet tells me VDC = VAC / (root 2). I thought it was VDC = VAC / (2 x root 2) - not something I want to get wrong!


DC is funny ...

Just received this;


We are very excited to announce that the next Audiojumble on Sunday 2nd March 2025 will be held at a new venue!

The Angel Centre in Tonbridge has been our home for 27 years and has been an important part of our history but, for the reasons detailed below, we need to look to ...

These are nominally industrial valve control connectors ...

Hmm. Is that 500V pin-to-pin or pin-to-case?

You can also run the pre-regulator sense wire to the base of the secondary regulator - it's not a Kelvin connection, but is the generally accepted way of ensuring the right voltage is delivered to where it's being used.

Twisting the appropriate wires and screening the umbilical also can help, as ...

42 arguably more so though perhaps?

He's been there, done that, moved on...

NJL3281D/NJL1302D now back in stock from the usual suspects.

Pretty sure the reverse protection diode, D1, is not needed in this use case - the LT1085 datasheet is pretty clear. Also, for stability the regulator output cap, C6, is specified at a minimum of 22uF solid tantalum or 150uF Aluminium electrolytic - the capacitor multiplier will not be involved in ...

After many many years of faithful service, my Peak DCA 55 and LCR 40 are being replaced with the newer versions... I need the higher test current of the DCA 75 Pro, particularly for thyristors, so took advantage of an offer and upgraded both.

The existing ones, which are in perfect condition ...

"Trail camera" is the more common name.

I have some of these and they're ok.
