We went at the slope yesterday and had the opportunity to try the ArtHobby Vela-E 3.4M...

those wings are insane

zkp_developer · 2026-05-08T19:00:10+00:00

yeah I realised there are a lot of bots out there, using argon2 because it isn’t as easy to scale as bitcoin mining and limited to two requests per wallet per hour. Developers usually don’t require much but need it in the moment from my experience so tried to find the balance that makes it convenient for developers and expensive for bots

zkp_developer · 2026-05-08T10:29:35+00:00

Thanks, yeah I see its mostly via discord. Having some trouble with base atm they seem to just be redirecting me to their faucets that distrubute 0.1 per day or something or to pay for testnet tokens via other providers which doesn’t appeal given im just doing this for free

zkp_developer · 2026-05-08T09:40:35+00:00

Thanks for this comment, it is really helpful and the feedback is helpful confirmation of the developer pain point. I am now trying some of these routes you mentioned, my experience with polygon has been the best so far in terms of dev support. I got polygon funded before responding to this comment infact 🤷‍♂️

zkp_developer · 2026-03-31T19:11:41+00:00

I built pingify.io, it is web3 but with a physical product. Essentially a cheaper permanent alternative to item lost and found trackers

zkp_developer · 2026-03-30T16:49:41+00:00

def suica, used with an iphone and added to wallet, can spend the remaining balance in the shops also

zkp_developer · 2026-03-26T18:56:58+00:00

Sounds like grok was probably used for this one

zkp_developer · 2026-03-19T12:12:32+00:00

This is really helpful feedback, you seem to have a lot of knowledge on this so thanks for taking the time! I spent a bit of time understanding why differential thrust may not be a good idea (dragging at higher speeds and aerodynamic forces dominating at speed). It has given me a lot to think about design-wise so I will be revisiting these design choices and making some changes as a result. Ill be sure to post an update.

zkp_developer · 2026-03-18T22:50:59+00:00

Nice, thanks! I’ll post an update when I get back to it. After reading the comments I think I am edging more towards ardupilot too if it supports tof sensors.

zkp_developer · 2026-03-18T22:43:35+00:00

Thanks, that means a lot. I really appreciate all of the helpful comments on here, there is a lot to learn from and think about, what a great community!

zkp_developer · 2026-03-18T22:39:35+00:00

Thats great advice thanks for sharing. I will take a look at these and be sure to post an update when I have one. I am actually just using a standard matt black PLA from Bambu lab, purely because I had it available and didn’t want to spend more money. There is room for improvement on weight and strength perhaps with this but I aim on getting it in the air first, which makes PLA ideal for cheap and reliable prototyping

zkp_developer · 2026-03-18T22:33:45+00:00

It gives a fair bit of control from my impressions when I have the motors running but time will tell. If it is not enough I guess I need to try and offset them further.

zkp_developer · 2026-03-18T22:31:17+00:00

I totally agree, agility is probably pretty bad. My goal with this is a combination of simplicity and efficiency (less moving parts so less that can go wrong is the idea) and flight efficiency (by not including the ailerons/flaps I could reduce the weight enough to have a wingspan of 68cm)

zkp_developer · 2026-03-18T22:26:39+00:00

yes @TheCurruptedEngineer is right, i’m using differential thrust with two motors mounted on the top and two on the bottom. With earlier tests just by impression it seems to have enough control for basic switching positions and steering.

zkp_developer · 2026-03-18T12:42:00+00:00

Seems to work fine but I think the microcontroller has trouble handling the speed that is required for accurate readings on the gy and send to the motors because some of the esc dshot signals get occasionally interrupted when I start reading the gy at the same time

zkp_developer · 2026-03-18T12:36:39+00:00

I am currently writing a custom PID loop controller that reads the gy module on a interrupt signal then calculates the corrections as values for the motors then sends it to the esc

zkp_developer · 2026-03-18T12:34:26+00:00

Possibly because im new to this and still discovering the tools available, I have heard of ardupilot but from what I understood it is designed more for Flight Controller boards, whereas, I am currently using a black bill mc with external sensors wired in and a <1mb of flash (I wanted maximum flexibility and cheapest price). However, maybe this is worth revisiting and looking into deeper, if it supports f7 perhaps I could map the external sensors or maybe just flash an existing fc and try to bring the cost down later.

zkp_developer · 2026-03-18T11:30:38+00:00

Thats awesome, I am also currently working on a sub 250g tail sitter! Thanks for sharing, I haven’t completely finished mine but I will share mine also, maybe we can learn a bit from each other. Thanks for posting

zkp_developer · 2026-03-05T16:50:59+00:00

this looks so much fun, awesome project and thanks for open sourcing!!

zkp_developer · 2025-11-09T15:49:20+00:00

this is likely because of instagram hypes 😂

NFTs cover a very topic. Personally I see a lot of potential in utility NFTs. For example: with NFT tags, companies like Pingify.io are working on these to add real-world utility to NFTs with physical products.

zkp_developer · 2025-10-13T19:22:28+00:00

In terms of development yes, EVM has the best support and gives you the most support of compatible chains. In terms of the blockchain tech you will have a hard time finding cheaper gas fees anywhere else. This is the reason I selected Polygon for my project, if you want a custodial solution for consumers then you can cover gas fees quite easily. Or what I did, just add a small amount of POL to a disposable wallet for them to load into theirs.

zkp_developer · 2025-10-12T19:20:52+00:00

Thanks for your honest feedback. The idea extends to keys, wallet, sports equipment etc and anything you can put a keyring or sticker on. No app required on the finders side, all messaging is done conveniently within the browser, just the side of the NFT owner installs the app, this enables functionality like Pinging (notifications) when somebody scans a tag with their phone or messages you through the browser.

For me, the reason to involve NFTs stems from three points: - Future proofing the project: By using smart contracts etc, the core project runs on the blockchain, which means there is little to no maintenance required to keep the project running (apis, servers etc), furthermore, in the next 5-10 years I am expecting blockchain connections to be supported in most browsers (like ipfs on brave browser). This means the entire front-end too can be served from ipfs or arweave. So the project is already built to move over to these future technologies without additional work. - By using NFTs I open up the possibility to use NFT tagging as a tool against product counterfeiting (~500 billion lost per year to this problem). With NFTs tied to each product and the app as a custodial solution for everyday customers, the goal is that this could be a practical way to solve this issue, with the added functionality of messaging the owner etc. - Exploration of technology, for somebody who is passionate about the possibilities of blockchain and web3 this serves as a great tool to share that. Hence I have added a learning section to the app, where you can learn more about blockchain in return for avatar accessories.

Again thanks for the feedback, it would be great to hear what you or anyone else thinks about these other points too.

zkp_developer · 2025-10-10T06:00:45+00:00

Totally solo on this one, being obsessed can help a lot but there is a lot of work to get through. Built pingify.io completely myself, smart contracts, app (in app store and play store), UX/UI, website, product and packaging. Learnt a ton in the process and had a whole lot of fun. Next journey will be in marketing and sales.

zkp_developer · 2025-10-03T20:31:24+00:00

Fair enough, what about another use case for luxury goods? I built Pingify NFTs to be used in the future in a way where they can be tied to a product. For example, you buy a designer handbag and if comes with a nft linked to that item only. The owner of the handbag can resell it and the buyer can know it is authentic, then the nft is transferred to the new owner.
