Got some fun updates for everyone on what I’m working on.
Pushed out another quick video on the flipper repeaters.
Also I’m working on some other devices.
@Satur9 had a great idea for a flex LF antenna that I was able to prototype. However it just wasn’t viable. I was successfully able to extend the LF range however I was never able to successfully couple any card or implant when it was in the field.
So I’m back to looking at one of my older designs. I crowd sourced the testing of this particular unit. It was an 8 layer Fr4 board.
After making my own Hprobe I now can successfully get solid reads on LF. So I can see even without proper testing that old LF test I did was actually almost perfect.
So I think I was on the right track. The issue was this successfully extended the range for T55xx chips but was a wash for EM chips. I think I know why.
So I am revisiting this with some different ideas and I hope to eventually prototype something.
Next up I have two flavors of the same device I’m working on. This was a request by NVX and ZV8 from the RFID village. They use a business card with RFID stick on nails to visualize NFC fields. They asked if I could make something cleaner. Here’s what I came up with. One is more chaotic than the other.
This should be able to give a decent approximation of field strength of a reader.
And lastly something I have put together. Equip got some gears turning and I have an LF Antenna in the works to replace the one on the pm3 easy. It modeled well, but I won’t know until I get one made.
And that there is the rub. Getting one made.
I unfortunately will not be making any of these this year. Maybe not next year. The current state of the tariffs have put me in a complete standstill as I can’t afford to prototype these devices without incurring extensive costs. Each new product I usually gave to do at least two tuning runs to dial it in. Last year, for the entire year I spent almost 1k on tariffs. This year I’m now over 7k. And the shipping costs have also increased as I can no longer use DHL. So I made a decision to halt future prototyping of new products and just create a stock pile for when all this nonsense dies down.
Any ways these are some quick updates for everyone
