I'm not generally a fan of huge vehicles but sometimes you actually need one. My 4wd Expedition pulled >8000 lbs of boat and trailer straight up a steep hill to my house with shocking ease. I took it very carefully on the way back down, though. 🙂
One of my favorite vehicles ever was my 2007 MDX, which had an amazing combo of torque-vectored SH-AWD handling and capability. I sold it to a friend, still going strong after >200k miles.
Excited to hear some fun creations at Burning Amp, and I might even load up my new sub design for others to ogle. ;-)
iVTM4 is SH-AWD but a bit more biased towards the front. Either system is amazing on ice and snow and slippery surfaces. All it takes is ONE wheel with some traction and off you go... and in turns, well, it feels 2000 lbs lighter...
Best one I had was the TLX SH-AWD. That thing was a beast. Completely balanced.
Speaking of Audio... the ELS in those Acuras was simply awesome.

Not that anybody needs additional distractions, but if this is your thing, and you are arriving early, or are still planning your arrival, a 'maker fair' is going on just a little down the road from Petaluma in Vallejo the same weekend as Burning Amp. The entrance fee for Friday looks significantly cheaper than for Saturday/Sunday. See https://makerfaire.com/bay-area/ .
A lot of it seems kid-oriented, but not everything is. I know that the makers of the BikeOn bicycle clip-on motor kit will be there, for example.

Amp Camp Attendees (And anybody else who wants to look, of course...)
Zenductor 2, the amp we're building next Saturday, build guide can be found here:
https://www.diyaudio.com/community/threads/zenductor-2-amp-camp-24-version.418631/
Of course, we're going to go over all this at camp, but take a look now and familiarize yourself beforehand. Enjoy!

Really stupid question: Is there a BAF T-shirt for this year?
Also, has anyone walked from the Petaluma Fairgrounds (where the airport bus stops) to the Best Western? Is that reasonable? (I tried looking on google maps and it's an overpass and the sidewalk situation looks a bit unclear)
Thanks,
Dennis

Not stupid at all.
Yes T-shirts will be available, we're just running last-minute.
Can't properly address the sidewalk question, but I suspect it's not going to be an issue. Looking on street view it appears to have sidewalk the entire way, however it's going to be awkward as pedestrian access and USA are usually mutually exclusive ideas...

T-shirt design. Thanks to Sheldon, a fellow member, for this amazing design!
Hmm... looking at last year's Zenductor. This one has double the caps, double the heatsinks, double the transistors, an inductor, nicer speaker jacks... is that the inductor ahead of the transformer?
Still, no cowbell.
Dang, I love that T-Shirt...
So, what's the power rating this time? 10 wpc?
BTW, I just looked at the build guide. Awesome job by all involved... the amp, the guide, the pictures.... etc... see you soon.

(I) Assume you set the bias potentiometer P1 in such a way that 2.00 amperes of DC current flows in the inductor. 2.00 amps is the absolute maximum current permitted by the manufacturer's engineering datasheet. Calculate the theoretical maximum possible RMS power when driving a 1 kHz sinewave into an 8.0 ohm load.
(II) Now assume you are a bit more conservative, and you choose to run the inductor at less than its absolute maximum value. Because you don't want the inductor (or the MOSFET heatsinks!) to get super crikey blimey OMFG hot. So assume that you set the inductor's DC current to 1.4142 amperes instead. Again calculate the theoretical maximum possible RMS power when driving a 1 kHz sinewave into an 8.0 ohm load.
{some of the inductor's DC current flows in resistor R6, and the rest of the current flows in resistor R7, so measurements of inductor current are fairly simple}

Say, North of 7 watts being conservative.
On a clear day, I live by the Coast, it's foggy right now, with a couple of 10 inch cow bells for heat sinks we might reach 10 watts... and keep the inductor in a chilled chamber.
Thanks.
BTW, what's with the RED LED? I thought Nelson's designs all work better with a BLUE LED. Is he purposely derating these designs so they won't compete with the XS300?
