Prototype Testing of the 125KHz Repeater Project
I have been fortunate to test and use a number of @Hamspiced products, One in particular was outstanding.
The High Frequency NFC repeaters were AMAZING.
That “problem” of struggling to get a read on stubborn readers and phones etc. was solved and now anybody can go to his Tindie Store and grab a suitable repeater for themselves which I highly reccomend, it has seriously enhanced the implant user experience.
The next “Problem”
Low Frequency
As far as I am aware nobody has seriously tried to create a LF repeater.
Hammy decided to tackle this, spending his own time and money to do so.
I was again fortunate to have the opportunity to test a prototype.
From the outset I believe Hammy was hopeful but uncertain how well they would perform.
He setup a spreadsheet for myself and two other testers.
I followed this through with a couple of readers and number of LF devices.
The results I got were a mixed bag, but unfortunately, not even close to the success of the HF.
Infact, in most situations the repeater served to block signals rather than repeat them.
HOWEVER
There was one notable exception to this.
And bearing in mind I only tested on 2 of the initial 3 readers I had planned to
With the Flipper Zero and xSeries implants (NExT & xMagic) I actualy got noticable improvemet in range
See below a snapshot of the results
-Baseline was No repeater
-The D1 in mm was the stand off of the repeater from the reader
- The NExT & xMagic column was the max distance from the reader I got a succesful read.
(not sure if this is the method hammy wanted, but the testing was consistent and the figures were solid)
As you can see, there are some very good looking numbers in there
Although this is not what I would call a successful or saleable product, as a protype it has served its purpose and hopefully Hammy can use the testing figures to decide whether it is worth pursuing …or not.
I consider myself privilaged to be given the opportunity to carry out some testing.
Thanks @Hamspiced
Hammy was understandably disapointed, but this was the message I sent to him and I stand by it
It’s still better than anybody else has done
Often misquoted, but the message is the same
'I have not failed, but found 1000 ways to not make a light bulb ’
Giving this a rating is really difficult:
If I was rating Hammy’s dedication to the community and this project, it’s an easy

If I’m rating the prototype as a physical product, is another

If I’m rating this for performance, I have rated this a

I would have given it one star if it was only a little range improvement, but the range was clearly much better, I didn’t give it 3 stars or more because it was only xSeries and only Flipper
