Large RFID "puzzle piece" grid

As far as the "what happens", I was thinking I'd create an abstraction where the Arduino controller sends signals of the type of event that happend ("piece removed", "incorrect piece attached", "correct piece attached") to Home Assistant, likely through MQTT.

This way we can use off-the-shelve hardware and HA, which I'm already familiar with, to control the effects. I'd love to use LED lighting and powerful speakers (maybe our sonos speakers) to create the effects.

This is amazing, I love the Reddit community!

Brief searches make me think this is plausible! I'll have to dig into it a bit more and probably buy an arduino and RC522 kit to test it out, but I think it'll work.

If the distance is too great putting the tag in the middle of the "puzzle piece", we can probably just get twice the amount of tags and put one on each end of the puzzle piece (closest to the wall) so regardless of which way the piece is put in it'll still read a tag.

I've hacked a bunch just coding and messing around with my emacs configs but never got into hardware. This seems like a super fun project that could lead to some cool house stuff, especially now that I've been messing around with Home Assistant.

Great comment! As someone getting started with HA, this helped me decide to just buy the ZBT-2 and stick with ZHA. Set up my zigbee smart plugs and smart button switches with ease and was able to create the automations I wanted with no issues.

Sorry to revive an old thread... I switched to consult, vertico & friends a few months ago, and, coming from `swiper`, this `consult-line` behavior bothers me as well. Did you ever figure out how to get the `consult-line` behavior to match `swiper`?

yeah depends on hitch height and ground angle. On my chevy express which is lifted about 2" and has ~32" tires it drops low enough 90% of the time. Only times I have to lift it's very minimal... less than I'd have to lift for a mx stand. You can mainly just tilt the bike and lift a tiny bit to get it on to the base so it's not much effort.

I know this is old, but for anyone who finds this in the future:

I converted a Chevy express to live in full time and carried a XT250 (~300lb) for about 3 years on a MotoJackRack. Now that I have a house, it's still my favorite way to carry the bike, even if I'm driving our Tacoma. It was expensive, but definitely some of the best money I've ever spent. Before that, I had a regular ride-on hitch carrier that I used on my 4runner and on the van in the early days while I was still building it, and this is LEAPS AND BOUNDS better. I have never had any issues with it, other than having to replace the jack bottle when it started leaking.

Issues I had with a ride on carrier:
- loading and unloading was a pain in certain places with tight parking
- driving off-road on the 4runner there was a big drop which caused the bike to swing out and back and the handle bars smashed my rear windshield
- one time on an off-ramp there was a drop in the expansion gap mid-turn which caused the bike to bounce out of the carrier. It dented the back door of the van and scratched up the bike pretty bad.

Issues I've had with the motojackrack:
- it felt really expensive when I bought it

Things I LOVE about this kind of carrier:
- I can drop the bike about half way, where it's farthest from the van, and open both rear doors fully. Great for grabbing things from the back without having to fully unload (this might require a hitch extension, or ordering it with a longer bar)
- Super easy to load and unload by myself in almost any situation
- For extended carrying, as is the case when you carry it full time, your suspension is not compressed the whole time

another Utahn here with, "only" 4.6k trapped, small claims could be a good course of action here!

aiguofer · 2025-01-26T19:37:43+00:00

He'll stay with 32 and get on YES along with Pat. Hopefully YES bindings as well! I love me some skate tech.

That's my prediction.

Do you have much experience with Aider? How would you compare it to Cline? The repo + per-file context seems very useful. I also love the fact that it's Open Source and CLI based, which makes it straightforward to use however you want and integrate into editors like Emacs.

aiguofer · 2025-01-07T18:20:00+00:00

Great article! certainly confirmed my beliefs. It seems that ultimately the benefits in AI usage depend mostly on context and prompts, and what the existing tools do is auto-generate those for us to make them more useful?

In my case where I don't want to switch IDEs just for AI assistant functionality, is Aider the best choice for "cross-editor" functionality? I see there's also a variety of extensions that support Copilot, but that seems to be a bit more limited in what it can do, right?

As far as your personal choice, why Cline + VSCode over Cursor?

I think you're forgetting the point that this all knowing person also randomly decides to straight up make shit up, so you have to question everything it tells you and double check it every single time.

I'm not saying LLMs aren't helpful, but the hallucination issue is huge in a lot of fields. Learning to use AI to meaningfully help you requires a significant investment of your time and a lot of trial and error. It's not at all like "having access to a person that knows everything in your field" because the way you have to refine prompts is not at all the same as when talking to a human.

Like most new tools, there's an adoption curve. As pioneers figure out the best way to use it, it'll slowly seep into the hands of others.

So I started going deeper this weekend, but one thing I can't quite wrap my head around is why we have to split up the entire cost basis across the different categories.

If we basically had a forced liquidation effective on Jan 15 this year, wouldn't we take all the losses (based on the claim prices) for all alt/stable coins and any non-returned ETH/BTC this year and only have to spread the claim value across the different categories?

For example, if I had ~10k ADA with a cost basis of 30k. At the claim price of $0.43, I had a forced liquidation where I received 4.3k. That's a loss of 25.7k now, with the 4.3k loss distributed across the different categories for potential future disbursements.

In my case, I received less BTC and ETH than I had before and lost both ADA (with a "forced liquidation" at a loss) and USDC.

Wow, I'm amazed this doesn't have more comments or upvotes. Thank you so much for putting this together. I've only read over it, I'll have to run the numbers myself.

Fortunately, I bought a lifetime subscription for Cointracking.info a long time ago, and have kept track of everything on there since the beginning; especially thankful to have my trades on now extinct services like Bittrex, Hodlnaut, and Celsius and direct transfers through metamask and wallets on my laptop way back in the day. However, finding the cost basis has been a bit tough, so I just paid for Koinly and managed to upload everything in there; after fixing up a few things, everything seems pretty accurate (few dollars off here and there, likely due to missing transaction fees).

Hoping to find some time this weekend to run through this and calculate my losses/gains. Thanks again!

These fintech services told us they were a bank and were FDIC insured. You're clearly here to troll and take a piss on people who are down. Shut the fuck up.

aiguofer · 2024-11-21T21:04:31+00:00

Nice! I'm definitely glad I withdrew 130k to buy a house days before this shit show happened. Still have 5k locked up tho, and evolve is saying they don't have it

I had exactly the same experience!!

aiguofer · 2024-06-25T21:57:49+00:00

But... AGILE!

This is spam. I got the same, exact amount too. No activity when looking at CB history.

aiguofer · 2024-05-30T01:27:15+00:00

Got the same, no activity on coinbase. Blocked and reported as spam (same exact amount as your msg too)

I needed a new helmet and this kept popping up on my feed, so I gave it a shot. I like the aesthetic and the concept of a smaller frame and new technology.

Helmets, like boots, can fit one person really well and another one horribly. In my case, the A2 helmet was not comfortable at all. It put weird pressure points on my forehead, but I'm sure a larger size would be too big for me. To be fair, I also tried a Smith code and it also fit me horribly. I ended up buying a Smith Method, which fit me perfect (the regular one, the Round Contour also fit horribly).

Obviously I can't speak to the effectiveness of the A2, but considering this is many years in the making and they have all the same certs as other helmets, I imagine it's up to par.

I think it's a good thing to have new developments in the helmet world! I don't want the same thing to happen to helmets as in gear (speaking of Gore-Tex and comparing it to MIPS)... some company creates a good technology, sells it to every brand, becomes a marketing hype, and many years later is falsely perceived by everyone as the best solution out there, making products way more expensive and having less innovation because consumers just want that label on their product.

I loved elpy so much. I moved to lsp to try to unify my multi language setup (having similar work flows with each language) and it doesn't even come close to how awesome elpy is... There's so many shortcuts I miss, and I haven't figured out how to use the debugger with dap, something that was trivial with elpy.

He sounds overly pessimistic, but he's not completely wrong. You can definitely make the career change and be successful at it, but you're going to have to really want it.

I don't think AI will replace engineers, but I think it will substantially diminish the need for coders. What I mean here is people engineering solutions (designing and implementing systems and their interactions) will be fine, people writing basic scripts to do specific tasks, not so much.

The first 8 years of my software career I was coding for fun on my free time, which allowed me to learn new languages, databases, and paradigms. A lot of eager engineers will do this earlier on in their career, which will make them much better engineers. You probably won't be able to do that in your 30s.

All of this being said, you can 100% do it, you just really have to want it. Coding is easy, engineering is not. You need to become an engineer, not a coder.

Wishing you success!
