My name's not really Walter, but I do make things, occasionally, thoes things are videos.
PRUSA XL Input Shaper Bonkers Benchy 1st attempt. (OH GOD, I've been waiting so long for this)
PRUSA XL Input Shaper finally released, so I went and ran the Bonkers Benchy they provided. honestly, the quality is worse than what I've gotten from the MK4 and the MINI, and I think that's mainly due to the 0.6mm nozzle, and the limited volumetric flow of the nozel from really taking advantage of it. the first 2 layers also detached when I went to take it off the bed.
But, this is PRUSA, patience is the name of the game with them right now, and they always manage to make things better... eventually...

Rambling on about my CRAZY New Project w/a VESC 100/250 and 25KW Motor
Переглядів 6102 роки тому
After months of playing around with different parts, and steady progress here and there. I decided to clean up my desk enough to show off the status of my current project and how insane it's gonna be, As well as hearing me geek out over all the little things I've been toiling away with in the process. This project has me taking a regular gasoline powered outboard motor, and converting it to ele...
Attempting to disassemble/salvage solar cells from a tempered glass solar panel (Why you shouldn't)
Переглядів 21 тис.4 роки тому
I was attempting to cut out an 8 call section of this solar panel for a project. As you see in the video this ended up being a total failure, due to the nature of tempered glass. But, some important lessons were learned. 1) Tempered glass cannot be cut without destroying it, or heating it to thousands of degrees to de temper it. 2) The glass panel at least in the case of this solar panel provid...
Fog at 2am with a flashlight (Intl-Outdoor P60 Drop-In)
Переглядів 63011 років тому
I looked out my window and saw that there was a thick fog out tonight. So, I went to my local park, with 2 of my brightest flashlights and took some pictures and videos. The beams look amazing with the fog floating around in them. Flashlight specs: -Intl-Outdoor P-60 Dropin with XM-L2 T6 Emitter and textured reflector. -Solarforce L2T Host. Brightness is at maximum with a full but old battery.
TEC1-12706 Thermoelectric Peltier Cooler With liquid Cooling

A TEC1-12706 Thermoelectric Peltier Cooler Bought at Dealextreme dx.com/p/tec1-12706-semiconductor-thermoelectric-cooler-peltier-white-157283 Conected to an old liquid cooling system I had lying around and I hooked it all up to a power suply. I left it running for about 20 Mins and it got down to -4C
Really appreciate this video! I’m in the process of designing some solar shiete
Live and learn. Good video.
Thanks for uploading this. It seems to have educated quite a few people - including myself.
I'm wondering if you heat the tempered glass up to melt the glue then have someone else slowly lift it as you melt it would work? Maybe even somebody get like a thin but sturdy stick of some kind to slowly lift it carefully as the other person melts the glue. I think the glue would be still stuck to those cells. Maybe a good idea would be almost like a machine that heats up the glass part after you loosen it but has a suction cup for the glass to lift. It could be a thing too? Those are all the ideas I have . Thanks for showing us.
Cheers for the deets!
Thank you for sharing this! 🤙🤙
lol at the transition at 2:22. Thanks for the video.
you should do a build video on your enclosure.
Neat. You held the phone for 15 min? So with the input shaper on are you happy with it overall or think it's under baked right now? On functional parts do you foresee yourself using it? The Bonker's benchy seems more of wishful -thinking- printing vs usable print.
Honestly, with the default 0.6mm nozzle, this thing is already pushing out plastic as fast as the current hotend can melt it. and the poor layer adhesion on this first print is strong evidence of that. What this thing really needs is a High flow nozel design so it can actually make proper use of a faster motion system.
Wow, that is a good looking printer and a good enclosure too
Well cutting that glass was bas idea from the start, little bit of heat and you could glue them off, shattered glass removal from panel is possible, but much harder
Thx man for not to embarrassed to post this... I was planning to do the same....
I had thought about buying a panel that was Broken and I thought to myself it made me hard to get the cells out because they're incapsulated In the whole thing would be a pain So I didn'tthanks for this video
Thinking about making a follow-up video? Curious what the outboard looks like with that motor.
cutting a solar panel in broad daylight if it succeeded is not ideal i suppose. You would end up shorting out the cells either physically or by water spray. One should attempt mods away from sunlight
Nice, was just wondering this and now I know, spot on vid. Ace. Thank you.
Thank you very much for publishing this!! It is very educational and it will certainly help many people, including me! At 0:24 I see "maximum system voltage 600V, 20A". Do you happen to know what the 6 Shottky diodes are? I guess they're rated at 600V, 10A. I plan to experiment with DIY of solar panels for home-lab use. I see that I can order bifacial cells from alibaba at $0.16/watt. The cells weigh 4 grams per watt, so shipping by air will be cheap. Tempered glass is actually expensive and heavy, so I'll be experimenting with lightweight solutions that certainly won't last for 25 years. In your video I see how the glass holds the cells, and it gives me ideas on the structural requirements. I think I should connect busbars between cells with enough wiggle-room, if there's no solid glass to prevent tearing of those connections if the cells move a bit. Hale protection might be handled by a cheap clear greenhouse plastic, that is elevated far enough. Oxygen/moisture might be handled by simply laminating some parts. The whole thing will be rather non-rigid. I'll see about handling strong gusts of wind.
I'm just interested in the tempered glass to make a small green houses.
Hi, Do you think it is possible to remove the glass and frame from the panels? To make a flexible panel?
If you watch the entire video you will see that its practically impossible
@@mahaniyama yep difficult even with a heat gun thanks for the response
It was at that point that Walter knew he ....
What connector is that are you using with all the Anderson connectors in it?
It's a Harting 6B size housing with a 3D printed adapter.
@@WalterWittMakes Thanks! can you share the 3D design file?
@@WalterWittMakes Also, where did you find that for so cheap!?
Cool project. I did a similar thing, but much more low budget. Be sure to choose the right outboard and prop. I used a 1,5kw motor for a 2,2 hp outboard. On paper it's a good fit but the outboard never uses more then 750w on high rpm. I would need a bigger prop but that's not possible on such a small outboard. Next time I will use a 3-4hp outboard for 1,5kw. Or at least one that can fit a bigger prop. Also, if you want a quiet motor. You have to pick an outboard with minimal vibration and you have to put alot of effort into aligning the motor to the shaft. Otherwise it will be very noisy.
cool project, share updates as you build pls
Not bad! You'll definitely want to make a video of the final product as you're testing it. Something "Stuff Made Here" style.
work at a solar company, we have alot of old panels. was wondering if i can take apart some. thanks for this. i wont even try now. lol.
You could try solvent or heatgun to melt the glue and remove the glass that way. Should not explode if you evenly heat it. Also note that glass in solar panels far is understood is not normal glass, but lead free glass. Normal glass would block sunlight and cause efficiency to drop.. how much i dont know. This same thing will cause some issues for me, since got shattered damaged but working new panel. I'l probably try slowly cut the glue between the cells and glass and maybe add plexy or something top of it.
Thanks for the video. I was planning on doing something similar, I wont attempt after your experience.
those cells probably laminated with Eva films (Ethyl Vinyl Acetate) and i think if you left them in toluene or xylene solution for a day they can come off by theirselves.
I was just givin a busted panel, I'm gonna go pour some xylene and report back..
@@Miximinium becareful tho, its highly flammable.
@@Miximinium and now!!!????
results ?
@@awesomed007 no dice. The Xylene had a small effect, it has potential. But that potentiality would require a submersion tank and I'm not looking to drop $1000 on petrochemicals.
Must be an impressive glue they use. Has to high heat and stick to glass must be impressive glue. Be nice if solvent. Surprised you didn’t try and heat the broken glass to a high heat and try scrapping the broken glass off?
Yeah I thought he was going to start picking the glass off
@@stupidscruff5794 might have been a deliberate set-up. To stop people trying. But that glue must do high heat and uv. So it's better than u can buy that's for sure...maybe a solvent though ? Impressive.
I wonder if you could melt the glue off with a heat gun.
- you would be best off to heat up the whole panel (or a large area) at once- to remove functional cells. - these things are made once - to be scrapped and recycled in a glass furnace at the end of life - metals recovery...
Tempered glass shatters if even one spot cracks, but it is stronger than untempered glass.
Sorry for your misfortune, but, thanks for sharing this. Saved me a lot of aggravation. :-)
I think one must think and wait before doing anything didn't do before
You only learn through experience. Gotta try stuff.
Nice experiment. Wish we could've seen it when the whole pane shattered like that. I suspect it's like when you use one of those piercing tools to shatter a cars window. Instant shatter. So what can be done to reclaim old panels then? Not much there to re-cycle.. maybe the aluminum frames?
Use them for yard art
Individuals cells are super cheap from china. This wasn't a wise move.
Your cost our education. Thanks for posting the "fail".
I couldn't find anything on the internet about salvaging cells from a cracked panel. Looks like I dodged a bullet with my ambitious plan.
🤣🤣🤣😂😂😂🤣
Thanks for the experiment and your effort. I was going to fix a solar panel thinking I could get to the tracks on the front side of the glass and re-wire them but that seems futile. One of my good panel produces 60V (open circuit voltage) with 4 sections of 15V in series. Some of the panels I have produced 30V, some 45V etc. I am sure the individual cells are OK, but there are some connection problems after being used for 15 years. If I can rewire them to 15V (4 in parallel) and get 4 times the current that would be good deal.
The silver in those panels is easily worth 150
20 grams per pannel. I don't think so
Thank you
Thanks for sharing..it was useful...it was nice attampt to check how its gonna behave
Hello, I made recently a very similar set up. I bought the same TEC in dx and other necesary things to do the liquid refrigeration: aluminum block, water pump, and silicone hose. Minimum temperature: -15 ºC
google translate kkkkkk sorry :D wanted to know if the peltier was the same link: D
um... What?
hello, I bought this the same dx, so it cools down a bit ... I just use aluminum heatsink with cooler, in fact that you are using this and the link? q I can to invest in a dissipagem best! : D thank you
