Hey I was hoping to get your advice.

My friend: 30 yrs old, married with 2 kids (4 yr old boy, 1 in the oven), smart guy, master in quantitative finance, phd candidate, loves coding, robotics, drones, building apps, practical guy who likes the "efficiency" of robotics and coding

He currently has a raspberry pi and learns about coding on his own time.

Gift ideas/ direction:

Arduino Starter Kits + other kits
Raspberry Pi project kits
3D printing equipment
Circuitry drawing / building like circuitscribe.com/products/super-plus-kit

Budget would be a couple hundred EUR I guess, we are a group of 8 friends (4 families) and we would all pitch in.

I know there are cool subscription kits for young adults / kids / beginners but I am not sure the value is there, they seem to overcharge for their "packaging" as I understand, and not really geared to adults.

Any ideas? or questions to consider/ ask?

Thanks in advance for your help.

Hi
I want to bury 100m of pic related under the ground, and push air through it.
Is there an easy way to calculate the airflow I will get through it?
I was thinking something like a computer case fan at each end (one sucking one blowing) which can be powered by batteries (this is going off-grid)
Would that be enough or would the air in the pipe be too heavy for such small fans to have any effect?
I want to bury it outside my offgrid cabin, then have the two ends inside. In summer it'll suck in hot air from above and push the cooled air out the other end, and in winter when it's 0 degrees it'll reverse and push out 10-12 degree air

If you use two battery powered computer fans like you say then you can easily maintain the temperature of a cabin year round. I live in a zone where we have snow in the winter and 90F or higher in the summer, and I use two computer fans to maintain the temperature in a 2 bedroom house.

You can reglaze it to keep the wind and rain out, and apply caulk to the top and sides of the trim outside. It won't undo the damage that is already done. I would be concerned that water may have gotten into the insulation below the window. Clean all the mold you can see with bleach as a bare minimum.

Nah. An impact driver will go through quite a few deck screws on a 2.0Ah project, you would be surprised. Not sure how long the 1.5Ah packs would run cutting metal with a hackzall, but you can easily get thru most afternoon projects on one charge with 12v drills and impact drivers. The M12 tools are definitely tech tools though, whether you’re zipping off a bunch of electrical panel covers or dealing with car engine covers and trim pieces, you can easily get a couple days work out of one charge.

The 12V packs are still 60% the power of the full size, so one of the 6.0Ah packs will run nearly as long as a 4.0Ah 18V pack, and 4.0Ah 18V packs in good health hold a whole lot of power, even when running saws pretty hard.

Hey /diy/,
I have a question about diamond cutting wheels.
Right now I'm finishing installation of paver bricks and due to the pattern I chose, I have to cut pavers around all of the perimeter (~180 meters total). For that purpose I'll rent a brick saw. The saw uses 350mm (14 inch) blades. And each milimeter of wear costs around 40 eurobucks. So the question is how fast do these blades wear? Maybe it would be more cost effective to buy a blade (from 80eur and up) than to rent it together with the saw?

>> No.1935953

Save yourself some bongbux and buy a second hand 9 inch makita grinder and a cheapo 2 pack of blades for 20 squid usually last me about 5 100sqm block paving jobs I'm assuming that is what you have to cut, they really aren't that hard

I have electronics that use “cell phone style” Li-ion batteries with 3 or 4 contacts. I’m tired of only having <1000mAh.

Your local machine shop probably outsources bulk sharpening even though they can do their own work. I'd copy success and find out who yours uses since the work is cheaper by far than new tooling. That's why my machinebuilderbro outsources most of his shops sharpening. It's not worth tying up a machinist.
