content: I think that nobody should ever contribute money to ANY flexible funding campaign, because there is always a go/no-go level for a project.Let's say a campaign seeking $100,000 got $500 worth of funding. Is the creator going to deliver? Almost certainly not. And definitely not if they have to put in much work to make the project happen.What if they get $99k out of $100k? Sure, they might well deliver. But somewhere in the middle is a threshold at which they just won't be able to (or won't care to) deliver. And since that threshold exists, why would they do a flex funding campaign in the first place?

content: I strongly dislike the Flex Funding model too (this has been beaten to death).Brent appears to have heard this feedback loud and clear, and the updated video pitch on the campaign reflects that. He has also added wording to the campaign text to address the concerns:QuoteAnd also:QuoteTo address the question actually asked by the OP:There are a very large number of purpose-built Arduino shields. All kinds of things from sensors to LCD panels to motor drivers to networking and storage (plus many others). The benefit is that if you want to test out a concept (i.e. you want to "prototype" an idea), you can simply plug in the appropriate shield(s) to the standard headers and start communicating with them immediately. No need to spin up a custom PCB or wire up a ton of stuff to a breadboard. This can let you make certain projects (or parts of certain projects) far more quickly than otherwise possible - and once you are done, then you can just unplug the shields and easily re-use them again later for other projects.Those shields are typically somewhat overpriced for the functionality, but in this case you are paying for the convenience and (hopefully) previously tested design.But even ignoring the Arduino shield pinout compatibility of the dev boards, $41 and $59 are fairly competitive prices for a 10kLE and 22kLE FPGA board. Especially one that is designed for easy soldering directly into a custom PCB.
Nerf football-sized "aquatic drone" powerful enough to tow 2 kids in floaties??? - Page 1

It was it as two motors that look like power supply fans and a LiFePO4 battery that lasts barely an hour. Color me sceptical; does anyone else feel the same?Other than that seemingly out of place claim, it looks like a fun Raspberry Pi based beach/pool companion.

Those propellers look pretty big and if the motors were beefy enough to turn those with any amount of speed it would definitely be able to tow a kid around. Typical RC toy boat props on a thing that size would be only about 15mm in diameter at most. $250? Well it is to be seen if there is a market at that price, I dunno.

Darkmatter Xbox Laptop & DIY Kit - Page 1

content: Hi guys. Newbie forum user techjango here.We'rea start-up based in Austin, Texas focusing on OSHW & DIY products and services. We recently launched akickstarter campaignto fund our Darkmatter project and thought that the users at this forum might be interested.Darkmatter is an Xbox 360 (*) Laptop Kit that you can use to convert your Xbox 360 into a portable gaming system replete with HD widescreen display, capacitive touch controls, USB ports and more. The project initially started simply as an effort to make a portable Xbox 360 system for ourselves, inspired by famed electronics hackerBen Heck- he's madeone-off mods in the past, andcontinues to dospecial orders at around $5000. We were pretty happy once we completed our own personal little mod, it was a fun learning experience (there were some frustrating points in the path, but all in all it was a good experience). Racking up the costs, they turned out to be much less than $5000, and we thought, “Why not make more of these, for other people?”. It's much cheaper to make, you learn a lot about soldering and electronics and such through the process, it allows you to play games in a small private setting and it's great for LAN parties. And so we named our little boy 'Darkmatter' and decided to crowd-fund it with kickstarter.Hereit is:We're still short of our funding goal, and would love to bring this product into the gaming and DIY/hacker community's hands. If you find this project interesting, please do help fund this on our kickstarter:www.kickstarter.com/projects/1360501894/darkmatter-xbox-laptop-and-diy-kit. We have reward levels all the way from $10 pledges (name-listing on website and a vote on color options) to $999 (fully assembled and tested Darkmatter Xbox Laptop, a how-to eBook and a skill badge)Wedemo'ed Darkmatterrecently at the Bay Area Maker Faire and got a very positive response. Ben Heck himself stopped by!We do hope our cause (andBen Heck's approval!) will convince you to support us. We've already been covered in prominent tech websites such asmashableandengadgetbut are still short of our funding goal. Help us bring this to you! Share around and pledge! We'll be releasing all our design files once the kickstarter is funded, so you can go make your very own mod!We'd love to hear your questions, comments and feedback. Feel free to leave them right here on this thread, or check out our kickstarter for common queries and updates on the project. Thanks for reading!----* more than just the Xbox 360. In light of the upcoming Xbox One release,we've announced support for it as well. It's essentially anOpen Laptop platformthat we're building, after all. Regardless, the Darkmatter would be a cool way to salvage your old '360 once the One comes out![Re-posted from the All About Circuits forums]

If you have feedback, feel free to respond here or create an issue on the Github page.Thanks,Zach

They're also pushing the disaster angle of the project, for complementing cellular networks. Of those uses, I think the most promising use is for local communication in developing countries. Even so, that would require a community investment, (the Mesh Extender) as well as an individual investment (a smart phone). I'm not sure how feasible this actually is. (As in, I actually don't know. Comments are welcome.)

content: When a project is relaunched after initial failure to fund, the original project page becomes very hard to reach. You need a perma-url saved before the replacement project is launched. At least if it has the same name as the one that failed to fully fund. I saw this with one of the projects I backed (backed it both times).Also, projects exist in a sort of limbo between the time they are created and the time they are published. Perhaps some never leave this state. These are only accessible if you happen to know the private url of the unpublished project. Usually these are shared by the project creator within a closed "inner circle" for feedback about their campaign wording/imagery/etc prior to launch. I have seen this on two projects where the creator of a successful project went on to kickstart another project later and asked some of the backers of the first project to take a look and return some feedback before the new one was launched.Maybe those kinds of things put a dent in the missing 18%?

Why?As for the trustworthy part, it's not just the video, it's whether or not you can prove you have a chance of delivery.Two 16 year old kids who have (presumably) zero experience delivering a product, is well, not very convincing.It doesn't matter if you post daily updates, what do you have to show, now?Do you have any sort of track record of documenting progress on a project? (that would help a lot)If the answer is nothing, then I don't think many people are going to back two kids to have a go at developing a 3D printer from scratch. The odds that you can deliver a tangible product at the end are obviously not good. So unless people are just going to back some kids to "have a go", then I suspect this one isn't going to fly.

content: I started using them a few months ago for storing coffee beans and snacks at home, and honestly, I didn’t realize how much of a difference they make compared to regular ziplocks. The beans stay fresh way longer, and the bags don’t get that greasy feel after a while. I even tried making a few with different colors and little labels just for fun it feels kind of cool to have everything looking “branded” even though it’s just for personal use.One thing I noticed though, the thickness really matters. I ordered some super thin ones at first, and they tore way too easily. The thickerSpam link removedwith the resealable zip are way better. I also came across this random guide about sealing tips if anyone’s curious.Now I’m wondering, do any of you use custom Mylar bags for long-term storage (like dried food, herbs, etc.), or do you just stick to jars and containers? Curious what works best for you.

I have 6 of them in my small print farm and they are a solid reliable workhorse.However you don't say what it is you want to print. If its Miniatures then you would be better with a resin printer - if you are able to deal with the smell and mess.

The standard 1kg spool seems too small. 10kg and 25kg seem large enough that running out mid print would no longer be an issue.However, when I look online it seems that a 25kg spool of PLA cost $600US ($24/kg) while 1kg spools are only $13 ($13/kg).Am I missing something? I'd think that buying in bulk would lead to a lower price, not a higher one.

content: There is a pretty wide variety in filament cost. A 1 kg spool of PLA can cost between $11 and $25 depending on the brand, color, tolerance, and blend. So unless you are talking about the same filament from the same manufacturer and the same vendor, I don't think there is reason to think size is affecting the price at all.25 kg is an extremely unusual size. The only one I found in a quick search is "Push Plastic" which is indeed $600, but they also sell 1 kg spools for $25. On the other hand, Elegoo sells 5 kg spools for $65:https://us.elegoo.com/products/rapid-pla-plus-filament-1-75mm-colored-5kg-for-orangestorm-gigaAs for whether a 25 kg spool is a good idea, I would say no, at least on your typical consumer 3d printer. Stick to 1, 3, or _maybe_ 5 kg spools. Even the print farms I have seen don't go bigger than 5 kg usually -- that will run for a lot of hours and a lot of prints. Then have a filament runout sensor and just load a new spool when needed. If you want uninterrupted continuous printing, get a filament changer like the Bambu AMS. It will let you load multiple lanes with the same filament and auto-switch when it runs empty.Consumer 3d printers generally have the spool just mounted on some rollers and rely on the extruder motor or the head movement to unspool the filament. The heavier and larger the spool, the more inertia it has and the more likely to cause print artifacts or even skipping. There are a few printers that have motorized feed that takes a load off the extruder, but every one I have seen is part of a multi-filament setup.

content: I've used clear PVC pipe primer. It has both MEK and tetrahydrofuran which can dissolve PLA. The cement itself includes dissolved PVC, which is why I've used the primer. Solvent welding this way doesn't work nearly as well as acetone on ABS does. While it can soften and sticky the surfaces, they still are quite hard. So when you push the two parts together, you need extremely flat surfaces. Layer lines are enough to be a problem. I've broken apart welded joins and seen how the adhesion didn't fully cover the whole surfaces.I've also used acrylic cement for the dichloromethane. That seemed to work better for me, but it is super difficult to acquire these days -- DCM has plenty of health risks.I agree with your approach of softening the surface as well as clamping them together. That gives you the best odds for a good clamp. I'm sure what type of PLA you use can make a difference as many are some kind of proprietary blend.

If you want it flush with the bottom add a translation before the module calls like:translate([0,0,bottom_plate_h]) top(example1, length);translate([0,0,bottom_plate_h]) btm(example1, length);Normally your slicer should automatically compensate for this.

content: There is also the 'print two objects' approach. Print the text STL file direct on the build plate at most two layers thick, without any brim. Remove any skirt without disturbing the text. Cut out the text from the bottom of the main object to the same depth, render to STL and slice with no support or interior brims, and enough Z-hop to clear the text. Manually change filament and purge. Print the main STL over the top of the text and it should bond properly.If using auto bed levelling be careful of positioning so the probe doesn't hit the existing text when Z homing for the second object. If your slicer auto-centers parts you may need to add some dummy 'blobs' one layer high, separate from the part at the corners in both STL files to get the text and main object to align.

It senses the metal underlaying the build plate surface, so if you aren't running a PEI coated spring steel build plate its probably not going to work, though it *may* be suitable for *thin* PEI, glass or Garolite, over an aluminum heat spreader plate, with some loss of accuracy. Its only usable with Klipper or similar controllers as analog bed levelling sensors aren't supported in Marlin based firmware.
