A couple of years back, we got a Bolt and had a bunch of electrical work done to support charging in the garage. Current state:

  • 200A service to the house, with a freshly rebuilt panel
  • Solar with battery backup (Enphase equipment)
  • 100A subpanel in the garage (significant loads: freezer, garage door openers, EVSE)
  • Old dumb Siemens EVSE on a 50A circuit on the subpanel (plugged in)
  • Emporia Vue monitors in the main panel and subpanel

Now we're getting a second EV, so we want a second charger. I believe we have plenty of load overhead in the 200A service for this, but not in the 100A subpanel in the garage. We don't actually put that many miles on our cars, so restricting the charging

Help, I have too many knives! These are all fine blades, but they're just not getting the use they deserve in my kitchen--and I could use the cash for more knives and tattoos :)

ALL SOLD, THANKS!

All prices are in USD and include CONUS shipping from northeast US, payment via PayPal or Google Pay. I'm open to shipping internationally but will add a surcharge for the difference in price. If you buy more than one, I'll take $20 per knife off the total. I'll give each knife a fresh edge before shipping it, unless you want me to leave it as-is for whatever reason. Feel free to post any questions; DM to discuss detai

Howdy! When we bought our house (~1975 raised ranch in New England), we knew that the upstairs hall bathroom (roughly 5x6.5) had been re-tiled after previous tenants flooded it. Unfortunately, it seems that the work was shoddy--within a year, the mortar had failed and the tiles were loose. We finally got into gear to replace them, so I removed the vanity and toilet and pulled up the tiles. The plywood underlayment was in pretty rough shape, so I pulled that up too, and discovered that the subfloor is planks (1x10s laid perpendicular and nailed to 2x8 joists at roughly 16" spacing, see pics below). What's more, some of the planks are in bad shape; in particular, the ones by the toilet flange

My subwoofer's built-in amplifier has an automatic sleep circuit; when it detects no signal on the line for a certain period of time, it cuts the power to the whole thing.

At least, that's the idea. What actually happens is, when the amp is in this sleep mode, the subwoofer makes a fairly loud sporadic crackling/popping noise. When there's signal on the line and the amp is live, it works perfectly (and is completely silent before the sleep kicks in), so the problem presumably lies somewhere on the circuit that only goes hot when the sleep mode is active. What kind of component could this be? What should I be looking for on the amplifier board, and how can I test the relevant components to s

I took a lot of pictures during my brew today, illustrating how a brew-day works with my mechanically-automated two-tier indoor RIMS system. Technical highlights:

  • All-electric system with no 240V wiring (a heating element suffices for mash, and the heating element together with my electric stove are plenty for boiling 8+ gallons of wort)
  • PID-controlled temperature-regulated mash
  • Set-it-and-forget-it continuous-recirculation mash (thanks to a float valve)

I continuously recirculate the entire volume of brew water during the mash; there's no sparging. This has a cost in efficiency, but I've found that consistency and flavor are much improved over the batch
