... Cat 12 Year old Snow Beast looks most like!

12V - price, power supply, heavy gauge wire, line drop ... 110VAC modules looks better in every way, except more intense points of light. 3 - 50W modules cost half as much as the 1 - 160W 12V module. Could put 6 in the same area, 300w 110VAC same price at 160W 12VDC, using mains voltage over light g...

Heatsinking will definitely become advisable as voltage is increased to 12V+, monitor closely! 200w into power supply is 80% efficient = 160w 12V 40w heat. 160w LED is ~20% efficient = 32w light 128w heat. 110VAC COB typically use a bridge rectifier and small cap(?) to push ~158DC through ~48s LED....

Any computer PS should supply a good 12V high Amps, I stocked up on Dell DA-2's for 12V 18A in a nice package, about $10 each in quantity. LED panel might draw 160w at 14V but likely less than 60w at 11V. Voltage >> brightness is more exponential than linear! Higher voltage permanently dims LEDs, so...

"Pollen "dies" quickly at 80ºF+". 85ºF and 90ºF Thermostats for fans will be set near roof, leaving temp at plants noticeably lower, with natural (unpowered) convection for milder temps. Having suffered multiple nights in the single digits Fahrenheit, everything except perennial herbs should be dead...

Oh crap! Been so busy ... forgot to mind the snow, Snow on the side streets and slush on the mains this morning! Don't remember where I stored the shovel, think I know where the salt is, been kicking it every time I delve into deep storage ... will need hammer to break it from solid mass to spreadab...

As the Hub Motor Turns slower and the Lipo Fire Burns dimmer. Try not to feel old. Can we reverse aging ??? Imagine that!!

Well, with proper diet and exercise you can extend and better enjoy your life ... or prolong the misery ...

Little improvement from 2nd week+ on De-sulfator. Battery 1 - 12.5Ah from 60Ah battery (21%) Let charge on desulfate setting for 1 week Battery 1.1 - 21.25Ah from 60Ah battery (35.4%) A 70% usable capacity increase from 1 week on desulfator! Will test weekly and post up results. Battery 1.2 - 22.5Ah...

. ... Greenhouse Progress - Season 1 Down in the teens, too much cold! High Tunnel not designed for prolonged freezing, effective for frosts and brief cold ... Basil all frozen and many of the Tomatoes and Peppers were killed, everything except some Herbs took damage. High Tunnel provided a 5-6 wee...

You can probably fix your money, and health, woes by giving up cigarettes and beer?

Tried to distribute the ripe and, as much as possible, the Green Tomatoes. Everything with some color was matched and placed in separate bags with an Apple, or 2. Variety was from nearly ripe to the leftovers at green, with no color. Will report on degree of success and time required from each degre...

Running 1750w of electric heat and a fan to distribute it. Hoping to keep everything alive through the night, tomorrow colder, not getting above freezing and into the teens at night. Will be harvesting out for tomorrows distribution including Green Tomatoes (fried green Tomatoes is a hick delicacy)...

Been riding my refurbed Watseka most of the Summer ... Just picked up newer version, the NAKTO City Electric Bicycle CAMEL Women 26" Black. Nakto.jpg Complete with plastic basket. I thought the Watseka was in bad shape ... this is a truish Halloween comedy of horrors! But 1st, gave the guy $50 for a...

I cleaned out someones inventory of odd length pieces, don't remember the size. Pulled long and squashed flat it is about 5/16" wide. Works good for me, guessing about 8ga? However, been using a lighter gauge in my power tool upgrades and have had 2 packs fail do to degraded-broken TCB. Just not hea...

Running 3 - 12V 40w heating elements from solar panel into 250gallon water tank to store solar energy against nightly cold. Might resort to grid electric heat assist for the forecasted 19ºF Friday night. Time to empty and upturn the outside rain barrels, try to save the goldfish. Garden has Peas sti...

Lens reflector kits for 20-30-50w COB LEDs

$13.29 for 10

Has weather seal, covers live connections. Hot melt or Silicone as alternatives.

MeanWell S-150-12-15 for supply with trim-able brightness?
Likely 160w@14V, 100w or less @12V?

Cycling individual cells and have many over 2500mAh and several @ 3000mAh+. Looking good! Problem with LiFePO4 is monitoring for self-discharge. Voltage is very level from ~3.3V-3.2V and similar to SLA, static voltage seems to "idle" high, making precise voltage-capacity monitoring, confusing-proble...

Me too, 180Ah is IMO a very small bank. When one reaches 80% SoH I start looking to replace and scrap it. Especially with a power bank ... 180Ah @ 80% = 144Ah bank .. scrap it? Why not buy a 90Ah, add it and have a 234Ah bank for half the price, and longer life, of a new 180Ah? Deterioration of old...

Had Ice on the birdbaths in the garden this morning. Only the hardiest still growing. Swiss Chard, Onions, Beets ... Was 35ºF at 10am ... 70ºF in the greenhouse(with morning Sun). Buttoned down the greenhouse: Taped plastic over the vents in the peaks sealed the roll up sides by screwing 1/2" hose t...

I have found that lifespan deteriorates evenly if, C rate is based on actual capacity. 2000mAh cell might deteriorate .01% per cycle at 2A. = 1C 50% 1000mAh cell might deteriorate .04% per cycle at 2A (2C) but only .01% at 1A (1C). Maintaining same original charge\discharge rate produces accelerated...

Processing at .5A. Had some cells cycle at 2000mAh+. (higher Amp cycling proved extremely poor!) 1 metered 2500mAh+ charge and discharge. Will be cycling in batches of 10p using copper adhesive foil wrapped magnets. I have 2 iMax B8s with 5A capability so should be able to cycle test 20 cells per da...

Just replaced 2 60Ah SLA for a neighbor's mobility wheelchair. Charged and did a metered discharge on both old ones and got: Battery 1 - 12.5Ah from 60Ah battery Battery 2 - 5Ah from 60Ah battery. Concentrating on Battery 1 1st. Will continue weekly tests until improvement levels off. Than on to Ba...
