First day in two months the high has been below 55 and first day in almost 3 its snowed. Hopefully this bad luck isn't a sign of how things will go with the new toy i just took delivery of..

Al is home safely and with crockpot chicken pot pie on the menu I decided that some risk to global calamity was acceptable.

Thanks, it was a really good opportunity for me to get one with very low miles, only 10k. All vipers are stick, an auto of any type has never been offered. I wanted to get into a car like this now. I just dont see how something like it can ever be made again. Because of emission standards, fuel economy requirements and safety requirements (vipers went out of production due to not being able to meet safety in the USA). A normally aspirated 8.4L engine mated to a 3 petal 6 speed with giant rubber at all four corners. It's a dinosaur, in the driver's seat you will never be lulled into thinking you are driving something rationale or refined. That's what makes it special.

^ I guess they are catering to the bi-measurement-system-curious. This is Marin, after all. What do you think gave you "Freedom Units"? The Imperial System, that's what. Do you think the UK went to all the trouble of Brexit, just to use the metric system, thanks to that little upstart Napoleon. I think not!

Working on build a water cooling Uberamp. Snatched a cold plate off ebay. I'm looking for advice to mount the transistors. I dont think I should drill and tap into the cold plate. So I have 2 option: 1: 1/8 by 1 copper plates drilled to mount on the cold plate and sandwich the transistors in between. -----copper plate------- -----transistors---------- -----cold plate----------- 2: mount copper plates directly on the cold plate, drill mounting holes on the copper plates, counterbore the back side (the face contacting the cold plate). -----transistors---------- -----copper plate------- -----cold plate----------- Any suggestions? Here's a planned layout:

Alice in Chains – Down in a Hole (the unplugged version is nice, but the song works better with the noise and distortion of electric power – I think this is my favorite Alice in Chains song)

Good to know that 10th worked for you. I didn’t dare to buy smaller than 15th even it’s a short flute. When I did my digital attenuator I had 10th clearance so I had to make a conventional chemical etching. Same here, no luck with the V shaped things – probably only for the pros.

I just milled this board for a CNC probe I’m working on. Those are .01” slots. I’m surprised I could do this

Table updated! Also, some progress updates: I tested the timer, relay and LV sections on the Main Board and they all work as designed. I am very close to sending final boards to fab house for quotes. With some luck with remaining tests, it may happen this week. With that in mind, a few things we need to all think about and decide. Please share your thoughts on this thread: 1. A reminder - the GRHVxxx and GRLV boards will not work by themselves as stand alone regulators. The rectifiers, filter caps, current limit circuit for HV are on the Main Board. 2. You can use 78xx/79xx regulators to replace GRLV boards if so desired. In fact, that's how I tested the Main Board. 3. The default timer setup on the main board is about 45 seconds. You can change a couple parts to adjust. The timer and relay circuits are both optional and can also be replaced with external modules. 4. R7, 8, 9, 10 on the GRHVxxx board set the regulated output voltage. A couple of items to think about and decide: 1. We should consider, as I have mentioned before, if to have the GRHVxxx board either fully or partially assembled. I hand-soldered all the SMD parts on the main board. It's manageable. The GRHVxxx is another matter - it's small and operates on very high voltage. Soldering the HN4A51J part alone is no bargain. 2. This GB has dragged on for some time. If you have changed your mind about the item quantities, etc., please post them here and I will update the table. We need final counts to get quotes. More update to follow!

My transformers have arrived! and I have begun initial amp board testing. A few more mini T2 build notes/observations. Once the amp boards are completed using diode test on a multimeter across the leds will not make them light. The 2 red leds on the underside of the amp boards will not light if just heaters and + and -15V are applied... you need the high voltages too. The el34s heaters run at about -400V DC with respect to ground plane on the amp board, the 6922 heaters run just about 0V with respect to ground. The attachment holes in the pcb for the heatsink L bracket are plated and connected to the amp boards ground plane. So the L bracket, and therefore the heatsink and ultimately the entire case is connected to the pcb ground plane. I have decideed to turn the amp boards around so the 6922 are at the front... to me it looks more visually pleasing... 🙃

Can't stop listening to this. I thought it was a cover because of the ... specificity? ... of the title. ...but there's already a cover (but not a cover of a cover):

I know, right? And how did you get past me down the 🐇 🕳?

^^ Okay I didn't expect that to be good.. that was from a while ago.. cool to see they are still at it and pushing... and a raw track

That whole album is perfection.

Prince Street Girls How Susan Meiselas’s home neighborhood produced one of her most influential bodies of work – a study of adolescence, femininity and the gentrification of New York

I can't recall a way to change the bit rate. I'd go ahead and submit a ticket to MH. It is still a beta release so it maybe something that needs to be addressed on the next public beta.

Went for a walk in the rolling hills outside Novato with Joanne and some Brit's. I think some biscuit induced climate change made it somewhat breezier than we were anticipating. Later we went to Costco where the shelves seemed to be picked almost clean. I made it out with one of the last 4 slabs of Diet Coke. They were sold out of rice. The staff said it had been like that all week with people stocking up on dried goods. I can't think why? /s https://projects.sfchronicle.com/2020/coronavirus-map/

Tannoy Dimension TD12s driven by a pair of Mark Levinson No 333 monoblocks. Ho lee shit.

Even on YT, the production on this sounds off the charts good.

RIP James Lipton: https://www.hollywoodreporter.com/news/james-lipton-dead-actors-studio-909382 93 is a pretty damn good run.

Sure is. This is York. Settled 8000 years ago, resettled by the Romans as Eboracum in 71AD. And currently looks like this Same here. No snow or frost. So insect heaven. Gonna have to take care of ticks, which are becoming a real problem in the UK now. The UK Government said three days ago "use hand gel to clean your hands to protect against Coronavirus" so everyone in the UK went absolutely nuts, and the only remaining stocks are being sold for 10 times what they were at the end of last year. Even professional suppliers have run out - even the options of 5 liters (over a gallon) containers have run out. Yes - we had to stump up to buy some. Seller's market though, so it is what it is.

In the UK it is still stiff upper lip. We were in London yesterday (at the National Theatre on the South Bank). No sign of anyone in face masks, crowded tube, no panic buying, supermarket shelves fully stocked. But will we be flying anywhere on vacation this year? No chance. And from what the airline companies are saying, we are not the only one by a long shot. And climate change? We have had a conveyor belt of storms coming in from the Atlantic for the last three weeks. Whole slabs of the UK are flooded with towns and cities essentially underwater. We're OK, by the way - we are well above the Thames flood plain.
