Anything over 60 is fine, people stress way too much over cadence when it's really not that important until you're years into your cycling hobby. As a mountain biker, my cadence will go anywhere from 40-ish to well over 100 on any given ride, it's not a big deal. Yes there's an ideal cadence for max efficiency at higher power outputs which is around 85-90rpm, that's what you'd ride at if you're training hard or trying to win a race but for recreational riding and especially as a novice, it just doesn't matter yet. Ride whatever cadence feels best until you get serious enough about cycling that you're shaving your arms & legs for drag reduction & extra speed. 70rpm is perfectly fine and it's not going to wreck your joints or cause any bio-mechanical issues.

Rick doing his best to herd cats, and it is just one cat. Chris had all the cold brew that day. But he is amazing and engaging.

So question for the collective wisdom of this group: what cadence do you spin at? My natural cadence is probably low 70s, but it seems like consensus is 85-ish would be better. I can spin that fast but I need to force it for a while to build the muscle memory. Also, what a difference a professional bike fit makes as a novice. My saddle was too low and my cleats were mounted out of position. It seems like fixing those two issues alone has given me a free 20W, not to mention the more comfortable position on the bike. I’m still not sure I’m on the right saddle, but I’ll give it a few hundred miles post-fit to make sure.

A lot of those filament regulators focus on reducing the differential mode noise. I think the DHT would be more sensitive to common mode noise, because the filament itself is the cathode in the signal path. Depending on the circuit topology, you may or may not be able to bypass the noise to ground. The common mode noise starts from the secondary windings on the power transformer, and gets more complicated with the switching regulators noise riding on top of it. It depends more on the implementation than the pretty numbers in the datasheet. -

I had recently posted on FB about a visit to an Audio store where I heard a system approaching $500K list price. A hometown friend pinged me and - among other things - said he has a friend/classmate (Princeton I'd assume) who "runs Oswald Mills Audio." Maybe you can get a friend-of-friend-of-friend discount 🤣

Three kinds of switching mode filament supplies made in my kitchen. Right: Traco brick, only 5V with some fine adjustment, designed by Kevin Gilmore and slightly modified by me. Left: DC-DC Step Down Converter XL4015, adjustable voltage and current limiter, have used it for 2.5V to 6.3V. Middle: TPS62913 Low Ripple Buck Converter (green board) My own design but done with help of TI datasheet (all info needed is there). Copper color board is an Elekit regulator with 2A3 and 300B auto detection. I’ve added a trimmer for fine adjustment of voltage. All three seem to work all right with my electrostatic amplifiers. I also have Pete Millett, Tentlabs and Coleman filament regulators. They are all bulky with heat sinks and produces a lot of heat. Yes, I do agree. Yes, at some point it (probably) will be a different matter. -
Happy birthday you Dusty Chalk!

My favourite band in the world had their friend Clint Carney make a video for them as part of their Kickstarter. The song itself already tugged at my tear ducts, it's so powerful, and the video is everything I would have wished for and more: For those that don't know, or haven't followed Al1ce since 2020 (like I do), it is very rare that Tash goes without her stage makeup. I think there is meaning behind that choice in the video... For reference, the previous video that Clint Carney made for them is also a favourite:

No, I don't think so, but that's okay, their fanbase has grown by like a Brazillion since 2020, and I'm happy for them for that. Thanks everyone!

That's how I felt after hearing Oswald Mill Audio Imperia speakers at his loft space in DUMBO years ago with JP#s. Big speakers with intimate live sound.
