handcrafted LED powerhouse needs a major heat sink

Seguin Island lighthouse in Maine is visible up to 14 miles out. The LEDs replaced a 1 KW halogen bulb that was no longer practical when the underwater power line failed in 2019. If you ever wondered what it would be like inside your flashlight, here you go. Do not look into the light.

Check your Amazon invoices for sales tax. Two out of three orders this weekend charged regular sales tax on tax free weekend.

NIB Switch Lighting Co liquid filled LED bulbs from 2011

The Switch LQD cooling system actually filled the bulb with liquid silicone to distribute heat. They were a passing fancy but they look really futurismic. I found them in storage, still new in their packaging. I'd probably just open and use them like a 5 year old ripping Barbie out of her box like some kind of animal, so if someone wants to buy them I'll entertain offers. I am sure I paid real money for them back in the before time. PM me if you are interested. They do not appear to have leaked but I am not going to unbox for testing.

What lie does your digital MPG display tell you?

I have a 1994 4.0 and the overhead console tells me I averaged 21 MPG on a recent highway trip. Actual miles/gallons was 17.3 which is exactly what the car should be getting. Stock tire size and the speedo almost exactly matches GPS speed so it's just plain wrong.

Beware, bike path is now a linear playground

A kid dropped his backpack in front of me and ran off the path to retrieve a football. Then four little kids on bikes came flying at full speed down an embankment and one almost t-boned me when he couldn’t make the turn.

I recommend keeping your speed under 10 mph while passing through all the apartment complexes. Maybe I'll use the street through that area instead. Kids be kids, it’s on you to be safe. (edited for clarity)

The printer lives! (let me sing you the song of my people)

IT LIVES! https://imgur.com/a/aCPeaY7 (sound on!)

After failing with a "modern" USB to Parallel adapter and an Epson network print server, the thrift store gods sent me a USB 1.1 parallel adapter old enough to support my ancient printer. This makes me unreasonably happy. I also found 3 Tower of Power vinyl records in great shape so overall an excellent day for obsolete technology.

I spent $25 on a bit of nostalgia and will confuse the heck out of some youngsters today.

Dropping off a donation and popped inside a thrift store. Found a brand new looking Panasonic KXP 1080i dot matrix printer for $15. Last saw one like that in 1992 so I bought it for no reason whatever. Splashed another $10 for a USB-Centronics adapter. When I heard the song of the dot-matrix again I was inexplicably filled with joy. BTW, tractor feed paper has gotten EXPENSIVE and greenbar is almost unobtainable in 9.5x11.

I'm bringing it to the office today to share my happiness.

Update: total whiff on the USB adapter, this IEEE1284 USB adapter is incompatible with the ooold SPP parallel port. It would fail during the negotiation and reset. I ordered an Epsonnet print server off fleabay that I'll direct run to an empty ethernet port on my box. Now I have to get it working, my pride is on the line.

gifted a Nespresso machine, surprisingly efficient and suitable for small-scale solar

I'm a propane stove, hand ground pourover coffee kind of guy. I recently received a Nespresso Vertuo machine and a bunch of coffee pods so I decided to stick it on the watts-up meter to evaluate it for mid-day caffeine top-ups. I was super surprised to see that brewing 8 oz of coffee only used around 20 WH, flash heating water on demand rather than storing it hot. It uses 0.5 watts on standby and bursts between 350 and 1300 watts for under two minutes brewing a cup. That is totally manageable for my existing kitchen inverter and the vampire load won't matter because it will be completely powered off between uses.

It won't change my morning routine because I love grinding coffee and having a big pot ready for when the fam finally wakes up, but it has found a place in camp #2's minimalist kitchen.

Nothing’s wrong and I know the key trick, I just want to poke around. I’m wondering if anything is cheap enough to throw in the toolbox just in case? 1994 ZJ 4.0
