Flipper At Home

Me: "Mum, can we buy a flipper?"

Mum: "We have a flipper at home!"

NFCWhenever I see the flipper zero, I think to myself "ah that would be so cool to have, but I probably won't use it and have feature mentioned as a module somewhere.

So I wondered how I would do the discount version of a "Flipper Zero" and found this ST7735S display and ESP32-C3 

DIsclaimer: this is basically a joke and will never be as cool and thought threw as the flipper zero, don't buy things and expect solutions from me! Just because the hardware is there, doesn't mean there's software to support it.

    For 2-3 evenings I was working on "perfecting" the look of the menu on the small display, until I realised that the flipper zero has four menu styles (that I know of) . I got to a point where I was very pleased, having a "128x64" pixel area in orange, centered in a slightly brighter orange 160x80 area, which is the display size. 

    The other day I saw the LilyGO T-embed price reduced to 28€ with shipping, I had my eye on it for a while and decided to buy it as a second candidate. Keep in mind that it usually goes for 42€ instead. The external dimensions are almost the same and I can use the 320 x 170 as a 160 x 85 display by just doubling up the pixels.

    Today I received two ESP32-C3 boards, one with native USB CDC controller connected to the USB plug and one with a CH343 connected, plus two LCD boards, because why not, they were cheap! (I also got that fish console from prev post, why did I buy that??)

    I'm a bit irritated on why there are two versions, why would you want a board with an extra serial converter? To be able to use the GPIO pins 18 and 19, which are the USB pins for the integrated CDC? Well let's see what and how many pins I need then.

    I found this pinout diagram and expanded it, so it shows what pins are the LEDs connected to. 

    Here are the boards again:

    While browsing through "handheld console" I found this weird "plug into tv" consoles and it definitely has the "XYZ at home" vibe.

By change how did you actually get the firmware to play nice with the hardware

  Are you sure? yes | no

davedarko wrote 06/04/2023 at 17:48 point

I didn't, I "just" wrote arduino code that draws the menu in the same way :) it's in no way compatible

Hey Bryce,

thank you for the input - I'm currently heavily involved with hackspace stuff, so projects fall a bit short and this was a bit of an ironic "shit post" first. I do like to have some sort of small multitool though and had a good time to explore how to design a menu for the display - this will definitely be worked on, but on a slow pace.

have a nice one and thanks again

add wifi mesh or audiomodem, tnc etc.

  Are you sure? yes | no

davedarko wrote 04/12/2023 at 11:40 point

is that a request? :D sounds like a whole different usecase but also a software thing that should work on any esp32 board? 

  Are you sure? yes | no

zyndram wrote 04/12/2023 at 17:13 point

yes ;-)

for example or etc.

Simple sound modem with two jack + baofeng or other radio and can send mesh messages. Any radio could be turned into a network device.

  Are you sure? yes | no

I was taking a look into this a little earlier too, the main thing I was seeing that wasn't available hardware wise was the switchable band pass filtering on the CC1101 modules. The ones on ebay/ali are all set at one frequency (normally 433, but some are the 903 or such). The flippers analog front-end has a 3 way switchable filter set for each of the bands that the module can support, I think anything properly comparable would need to do something similar with the modules unless you're fine with only a single band.
Would be nice to find or build some module that uses the CC1101 but has a switchable analog front end, possibly into switchable antennas better tuned for each band, or like the flipper does with different end loadings of the antenna depending on the band.

  Are you sure? yes | no

davedarko wrote 04/11/2023 at 05:31 point

it's not gonna be the strongest signal, but it would still work with the one antenna setup. There's a CC1110 in the girltech im-me messenger and you can use it as a crude spectrometer for example. For an "at home" version I could live with a 433MHz module for using it in Germany.

  Are you sure? yes | no

zyndram wrote 04/12/2023 at 17:08 point

or 868MHz strongest signal and a lot of empty space/time

I saw a short on YT today where a guy uses a Flipper to tweak the smart meter on the side of his house. At least the meter was smart...

Seeing as Amazon is now no longer selling Flipper Zeros, building your own might be the only way to get one pretty soon.

  Are you sure? yes | no

I saw it in their shop recently, but I felt conscious about my money for once and thought 200 Euros would be too much for a device that might end up in the drawer anyways :D

There was a guy at Hackaday Berlin using it as a slide clicker, that was nice to see too! But I have so many modules flying around anyways, I should really build something with those. 

  Are you sure? yes | no
