Are there any places where a hobbyist could purchase a tag or reader?


Seems doubtful as this guy has spent a lot of time wigg the this and can’t get one.


If a workstation has Git installed on it, which I’d think would be the case for substantial number of engineers out there (…not just software engineers), grep is there due to Git BASH.


I have a hobby project where I am using UHF tags for counting poultry. The advantage that it gives me is long range (few meters) compared to LF / HF tags. QR code also wouldn't work due to size and distance.

Here's a video.

This looks immensely useful

I've been thinking about ways to count my chickens, making sure they return to the coop and don't get locked out at night. Most of the time all tge birds get in, but occasionally some will dawdle and wind up sitting outside a locked coop door.

You mention this can read for a couple meters. Can it read all the members of a flock, so I could mount a single transmitter in the ceiling if the coop, or is it one at a time, so something that should live above the door


I haven’t played with any stationary antennas but I think it’s possible.

The scanner that is used in the video has configuration for transmit power. At its maximum setting, the range is 15 feet with clear line of sight.

Tags with larger antennas, generally speaking, have longer range but might be too big for younger chickens.

So overall there are a lot of variables.


Looking at Chafon and some other vendors, they seem to have a decent amount that might work for what I want. Do you purchase your stuff from Aliexpress? Or is there another vendor worth using


Really nifty; can I ask what tags you are using? (are they off-the-shelf)

Would be interested in doing something similar



Maybe they could do some R&D to see if coffee could be used as ink.


I just put coffee in my printer to see...

It kinda works, but the printouts are very faint.

I was expecting it to clog immediately (the jets are ~10um), but it didn't.


Damn. The kind of friends I need in my life.


I'm not surprised if you used the Breakfast Blend. Did you try the Caffe Verona or Espresso Roast?


It was Lidl's red topped instant - don't even know the name - the jar with the red lid, and I made it pretty strong but without milk/sugar (which I thought would cook/burn onto the inside of the nozzle)


That's my printer recommends Bulletproof Coffee. The coconut oil helps ensure smooth flow without clogging while the MCTs improve coffee adhesion to the paper.


Sorry to bother you but I have so many questions! Like, did you actually do it or was it just a middle joke I didn't detect? If the former, wasn't you afraid the printer won't be usable after that experiment? Didn't that worry you? Do you often experiment in this way? (Just stopping there to give otherwise the list gets too long.)


I have literally hundreds of HP print heads from a project, many partly blocked or burned out (they burn if you send them the wrong signals, and like 10% of the time I hit 'break' on my debugger it burns a few jets out if they're firing at the time), and had a coffee sitting right next to my desk so thought "why not".


This is incredible - you should write a blog about it. I want to see what that printout looks like!


When the main project is done, there'll be a blog post and the coffee test will make an appearance!


I'm also super curious what one might get up to with that many print heads, so maybe there's two posts in there!


yeah, but can you bubble jet maybe a photo onto a flat white?


That is a stretch goal of my project, but right now I wouldn't be confident I have a method to flush out the OEM and probably toxic ink.


Similar things come to my mind with The Sims. Once the game was “over” (maybe you’ve reached the top job) you could still do all sorts of things… Some of them a bit masochistic.


I’ve been working on an animal management app for the last two years or so. It’s a hobby project so it’s not going very fast. Recently I’ve released a new version with support for one model of a UHF RFID reader. It allows me to count and identify my chickens from up to 15 feet away.
