The smart TV can use the 5 GHz, but doesn’t as it has a direct ethernet cable connection. Router is about 6m from the tv, but with no...

I was having trouble logging in to the router gateway, but am in now. It uses 2.4 and 5 GHz channels. The 2.4 channel width is already...

I can’t see much from the outside. No access panel for the power board so it’ll be a case of spudging horrible plastic clips all the way...

Model UE55NU8000T, with a ‘smart’ remote operating on Bluetooth (except for the power button, which is IR) and a normal one, which is...

The Rigol has arrived, and I’m just getting familiar with it and waiting for the 100x probes. It’s very nice to be able to capture...

If you insist, then. I’ve ordered the Rigol DHO804, which has some good reviews. Having four channels on the Fluke has been helpful, eg...

The VBRP was the much improved version. VB = Victor Balding, the founder and owner of Balding Engineering. RP = Richard Prime, the...

Yes, like most small-time machine users, I’ve set up the VFD and hoped for the best. This one’s been in use for a year; I have other old...

This, a 1961 Beaver VBRP:

Ok. I have to be careful about the selection of the resistors - running a VFD with the output open circuit can ruin it. Using high-value...

It was the multimeter measuring. The supply neutral is referenced to earth at the pole transformer, probably around 100m of cable length...

Thanks, the line trigger trick worked better, but the trace is either incomplete or slowly redrawn, presumably due to variations in line...

But the VFD isn’t a step-up type - the output is three-wire, effectively delta, 3ph at 240 Vrms phase and line voltage. It should, as I...

No neutral. The VFD output is 240 V P-P. How come it displayed the real 240 V mains ok?

Try as I might, I couldn’t get the scope to trigger properly. This is channels 1 and 2 on U and V terminals of the motor, scope set to...
