There's no good music on the radio tonight. The best thing I heard was some esperanto song on China Radio International on shortwave. I am so bored.

>>2998038It's a 3V lithium battery, you can get them in all sorts of form factors. Solder wires on one if you're in a pinch, though instead of that or a cell with leads, I'd want to replace it with a socket. Probably for a 2032 or 2430 or whatever it originally had, but upsiziing to a socket for something like a CR123A might be appealing. A rechargeable battery or supercapacitor might also work, a supercap is what my Hitachi oscilloscope has, though I can't say whether it had that stock.
>>2998045Yeah it uses a BR2032 with solder tabs. Can't use CR2032's as the battery chemistry is a bit different and there is some reverse current leakage through a diode in-circuit that causes the battery to leak. Thanks for the socket idea, I never thought of that. It would make future battery changes easier.
>>2998106Ah, it's a lower leakage chemistry. I don't see why it would matter if the voltage is the same, are you saying there's leakage current that goes back into the 2032?
I know prepping is a bit of a meme, but what are some of the best food items to store long term? Is rice one of the best emergency foods? It’s cheap, it lasts for a very long time if kept somewhere dry (relatively easy to store), and a person can survive off of it in dire situations.What does /diy/ think?

>>2998093>zoomer confused by common house appliance.*zoomer confused by black magic and numbers that don't add up along with some anon that could've ended this thread yesterday if he just addressed the amount of contacts that are in the bulb socket of the lamp.
>>2998073Nta, but you're thinking way too hard about this. The original post made perfect sense. By "dim and bright at the same time," he was talking about the filaments. There are only two contacts on a dimmable incandescent. >1st position: off>2nd position: dim filament only>3rd position: bright filament only (what you called medium)>4th position: bright and dim filament both active at the same time (full brightness)Lamps are either a 2 position switch, (no brightness adjustment), or 4 (3 total brightness settings out of 2 distinct filaments). It's not that hard.
>>2998095ffs, HOW DOES THE LAMP POWER TWO FILAMENTS WITH ONLY 2 CONTACT POINTS?!?!!? You would need at least 3, two hots, one neutral.How are none of you getting this, despite me specifically mentioning the bulb/lamp contacts in every post? That doesn't mean I don't want you to talk about them.
>>2998069There are actually multiple contacts on the bulb and the socket when there are multiple clicks on the switch not just hot and neutral. Its like neutral, hot, hot. Three clicks alternates between one hot or the other, than both at the same. Two I suppose would just do one or the other. Each filament is a different size, or brightness. My aunt had a three way lamp and it was all fucked so I had to learn a lot about this to fix it.

>>2998074>We had a pair of some German-made strippers but the name was rubbed off.If the brand color was yellow I would take a bet that it was a Jokari.They got a collection of wire strippers. One for every taste.If it was red/blue it was most likely Knipex. Great pliers but they also got wire strippers.
Tested these LEDs at 3.3V & 1kOhm resistor to see if I could use them in my game project as indicators. Current was about 1.4-1.6mA for all of them. All the reds are quite usable. They could use even larger resistors (maybe 1.5kOhm) to make them more even with the other colours. Clear yellow & green are okay too. The frosted yellows & greens are unusably dim even when viewed from the front. The green side on the two bipolar LEDs is a bit dim too. Maybe could try that one with 680R or something.
>>2998090Side view. I plan to ditch the frosted 5mm yellow&green and try the others with: - reds: 2.2k - yellow: 1.5k - green 5mm: 820R- green 3mm: 1k - bipolar red side: 1k- bipolar green side: 680R
>>2998092>I plan to ditch the frosted 5mm yellow&greenand yet, they are the fairest of hue, texture and coherencetruly high-borne princes of the landif they need a bit of extra current, you must give them their due, to thank them for their gift of harmony and beauty
>>2998090You could always run them from the battery or other upstream power source, but that will create a brightness variation with battery capacity if you use resistors, and I doubt you want to voltage mirror them. If you have a 5V rail I’d definitely use that.Also that yellow clear LED looks gnarly. Full of bubbles.
How dangerous is lead, if it's unlikely anybody will get cut and bleed while dealing with it?I'm interested in buying a sheet of it for making figurines I might sell, but I don't want to use it if I run the hazard of customers getting ill from it (or getting ill and blaming it on lead).

Hey /diy/,I want to frame a shipping container, not to live it but just turn it into a barI want to frame it, then put some cheap board up and put reclaimed wood I have layjng arou d as a feature wall/sIta not going to be air-tight after I cut the windows in but I have hears that condensation from the cold steel and air-cavity between the feamjng can lead to rotWith all the effot I am putting in Id hate to have to pull it all apart in a few yearsWhat should I do? Is it a problem if I am not living in it but just occasionally use it a few times a year?
>>2996688Why not use rigid foam panels instead of expansion foam? Seems like it might be cheaper and less waste.
>>2997922>The trick with containers is to eliminate the possibility of air touching the metal.I imagine he means with ridge foam there will always be water condensing on the inside. 1/2 year you will have wet walls and CEILING behind the ridge foam, and even if your interior dew-point only lasts a few hours, it will take more hours to dry, if it ever does.I'd engineer some positive yet filtered, constant flow through venting.
>>2998011It's going to happen with expansion foam, too. Seems like an overblown problem though. Massive amounts of condensation are only happening in rapid temperature changes, which really shouldn't be an issue.
>>2998016?unless he heats the fucking thing in winter in which case he will have tons of condensationframing the interior of a container seems retarded, just build a normal structure to whatever size you want, ur not saving money buying a container
>>2998080>unless he heats the fucking thing in winterThat would be a rapid temperature change, possibly. But it's unlikely a shipping container is going to have the thermal mass. Doesn't sound like he's going to be heating it anyway. But using your analogy, anon, your car will rust apart just sitting because the panels and insulation will keep the moisture trapped. It's just not how it works. I agree framing it seems rather pointless, though. At most it might reduce the noise, but unless someone is beating on the walls with a hammer, it shouldn't be that bad.
I just got a used neo max for $200 USD with the 5 watt laser etcher, both like new in box off fbmp. Last 3d printer I had was in 2012 and was a new makerbot replicator 2x, and it was horrendous. I am quite happy with this new printer thus far...However... I come to ask, is there any compelling reason not to swap this to direct drive from bowden, either with the official sprite kit or print the bracket myself. Its speed is already limited by the bed movement, so I am not sure I would lose much since its a slow one anyway, ringing probably wont be an issue, etc.Anyone else have knowledge of this setup?
>>2997931Why ask? Just do it. Also there is a 3D printing thread.
>>2997938suck my cock, post something relevant or kys.
>>2997931>Anyone else have knowledge of this setup?no
>>2997931>Anyone else have knowledge of this setup?now that I've spend some time thinking abouit it.Nah, still nothing.

6.75×5.25m total, comprised of two structures in one. solar shed is 2.5×5.25m. barn side is 4.25×5.25m.solar equipment shed was built by me and my 81-82 y/o (at the time) dad from 4/2023 to 6/2024. barn construction began 2/2025 and was bult mostly by me with some help from my wife. wife's rabbit business partner/friend and her husband helped install the steel roof and siding. the roll-up door arrives in 4 weeks, but the actual building(s) construction is complete as of 5/2026.solar shed houses inverter & batteries with our smaller 2440w array mounted on the roof. larger 4450w array is ground mounted just south of it. power to the house is buried in conduit that runs under the barn side. shed also stores building materials and garden tools. Barn side is dedicated to wife's rabbit business.shed side is 2x4 walls, 2x6 rafters, on concrete slab foundation, OSB sheathing and composition shingle roof. barn side is pole barn construction with 4x4 posts set 1m deep in concrete, furring strips between posts for steel R-panel siding and roof. there is one 2x4 stud wall on the north, also furred for steel siding, but it is not load bearing in the traditional sense. the barn currently has a dirt floor.all built on an extreme budget using lots of repurposed & scrap materials. shed cost aboot $975 all-in. barn was more expensive, less scrap/repurposed material @ $4,150. total structure $5,175 includes every screw, wire, conduit, panel, lumber, doors, window, concrete & trench machine rental.solar system provides 85%-110% of our power, total cost: $15,200. system layout designed by me, DIY install, grid-tied, non-export, self-consumption. all pricing in CAD. Dad's still happy, healthy and doing Dad stuff with Mum @ their house.
Next phase: HVAC installation. just arrived today. 100% paid for by livestock sales. Wife and I should be able to get it installed this weekend, and will post update.We opted for the hybrid AC/DC model. it is just the updated R32 version our our 2022 model 410-A units we have installed in our house. they can simultaneously switch between our home 120v AC and a dedicated PV array via internal inverter. this will allow us to replace our 8 Qcell 305w panels with newer 460w panels, then repurpose the older 305's DC direct power our existing Great Room HVAC and the new barn HVAC unit. this will remove 1200w-2600w burden from our household 120v solar/inverter/battery system. this means more PV available to our inverter and less import from The Grid.Overhead 1.8×2.4m roll-up door door has been held up 9 days past delivery date, waiting on some random part on backorder. spoke to the manufacturer today, updated delivery date is next week, July 8... allegedly.
Just got the 3rd wall frame up. How did I do?
>>2998012quality work, Anon. lumber looks true and framing is square. looks like youve got a overhead or double door opening. any windows or man-door planned for the 4th wall? Will it be steel roof & siding?what is its purpose? tool shed? Lawn equipment? Storage? A little bit of A, B and C?
>>2998060this fag bumping and hyping his own thread lmao
>>2997986 Me>>2998060 Me>>2998012Not Me.I updated my thread with this weekend's next step. if thats "bumping" then so be it. in that case, ill be "bumping" my thread again this weekend with the mini-split install and probably next weekend when I get the roll-up door and install it. I find it odd that participating and showing progress of ACTUAL DIY rather than just abandoning a project thread is so frowned upon in /DIY/.>>2998061all of that said, thanks for the "Bump" wanker.
Not this house or area, specifically, but WTF is the "landscape" for rehab on what is surely LEAD PAINT house that needs TLC and DIY?In 'Frisco, CA there was some scam where you'd get sued by neighbors who'd claim your lead got into their dirt, even though all dirt in SF has lead, and it was illegal to take samples before hand. No idea how that shake out or if still going on.But what about more "reasonable" areas? I'm I going to be "Catch-22" where I can't fix shit without building a NASA tier clean room 3 stories high, but I'm also going to be hit with "blight" fines?https://www.zillow.com/homedetails/432-Pine-Ave-Cumberland-MD-21502/36163766_zpid/

I am running a new water line from the meter. 3/4 copper was the plan but should I consider PEX? I like it because there will be fewer joints to fail if I do one run from the meter to the house.
>>2996657Nobody does it because you can much more easily drop the black PE pipe in and also never have to give a fuck again.

I live ludicrously far from all laundromats, they charge a pretty fucking penny for a wash and a full dry, and I have no vehicle, no friends willing to drive me to a mat, no family in my town, and churning clothes like butter in hot bathwater with the head of those detachable mop handles for 4 hours is starting to lose its luster. The drying I can take. Is there a faster or better alternative, especially a ghetto, simple one, when I live a poor life, mostly due to living costs?Don't say move. This is literally the best gig a fella like me can get. Not because of any record but because it's all bills paid and they didn't ask for a lease agreement.
>>2997901Cry about it
>>2996871Get less absorbant clothes. Sportswear is easily washed and dried.Wash individual items in the sink with a little handsoap or shampoo. You probably have limited space to dry everything at once anyway. Actually wringing things out is more effective than just soaking and limply moving them around.
