Works great.

For FlippenHeimer -Geiger Counter for the Flipper Zero

This is the first module for my flipper!
I used J321 tube instead because that's only one laying around.
Almost screwed up the pcb while soldering(rusty soldering iron damaged the pad on pcb)... but fortunately, it works!
And thanks for including the case for free.

p.s. I think it would be better if it had a button that switches between external buzzer and flipper's speaker.

Response from Erwin Ried | July 2, 2024

Hi! I though on not even adding the buzzer, but ended with the current design just thinking it was safer to have the "analog" buzzer since the flipper speaker relies on software, which might not be as safe (I am not saying this will save you from high radiation environments or something 😂, but conceptually). Great that you managed to make it work!

Best third party GPIO module for flipper zero

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

I received the Mayhem board in no time but I was unable to flash it as instructed, no matter what I tried. Erwin has been very responsive and helpful when I reached out for assistance : he didn't hesitate for a second and helped troubleshoot.

I didn't have a second flipper to test with, but I started suspecting something was not right with the device (rather than the board) when I tested the GPIO pins with a LED light.

I finally managed to convince Joom to reimburse me for what I suspected to be a defective flipper device. It took 5 months of back and forth emails with their support and ultimately, a PayPal claim for them to accept.

Long story short, I've since ordered a new flipper, and the Mayhem works great. As suspected, the flipper was the culprit.

The mayhem board is well designed and built and is one of the best GPIO module you can find for the flipper zero.

Response from Erwin Ried | May 20, 2024

Congrats on getting your broken flipper replaced! And thanks for sharing the journey.

The Mayhem

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

Couldn’t be happier with this module I’ve flashed and downloaded the firmware added a micro sd another radio module and a separate antenna for each module and the esp-32cam . Great customer service and fast shipping in my experience. Thanks again will be back for more stuff.

Response from Erwin Ried | May 10, 2024

Thank you, James! I'm thrilled you're doing hacks on it 🤓

Bill | April 1, 2024

Hmmm

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

No matter what I do with this board I cannot get it working. I gave reached out to the seller to no avail. I've followed his you tube and written instructions and it still doesn't work.
It looks excellent, the shipping was fast and it was well packaged but if it doesn't work its no good to me!

HELP!

Response from Erwin Ried | April 1, 2024

Hi! I'm sorry for the experience, can you write details of the issue via messages with your order number? If the unit was assembled/tested and somehow you got it broken I'll send you a new one or refund you right away

Maurizio | March 19, 2024

Grazie grazie!!

For FlippenHeimer -Geiger Counter for the Flipper Zero

The kit was a bit più tricky than I thought. I soldered one of the chips in reverse, which set me back a week on assembly. But when I contacted the seller, they were abbastanza cool to send me a new PCB. Now my Geiger counter works like a charm, and I'm super happy with it. I use it as a dice for boardgames to get truly random numbers 😂

Response from Erwin Ried | March 19, 2024

Great use! It's the ultimate in randomness – and radiation, but mostly randomness! 🧐

Maurizio | March 19, 2024

Awesome fantastica!

For Mayhem T-Shirt (Flipper/Portapack+HackRF)

This T-shirt, it's bello! Nobody really capisce cosa sia, but with those markings on the short sleeves, mi sento like un generale italiano wearing it.

Glad this shirt makes you feel like a italian general 💥 lol

The board EVERY flipper owner should have in their arsenal.

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

There is nothing bad I can say. I purchased the Deluxe Ultimate with Adamantium so my experience was plug-n-play. Faster shipment to the USA. I love the look of the Adamantium protectors, and my friends are very jealous of the cool design on the 2 dolphin-themed 64 microSD cards. I could not detect any weather stations using the internal cc1101 but with the Mayhem V2, I picked up over 5 just from my bed. I have not tested the range, but there is a huge difference between using the external cc1101 versus the internal. I can't wait to give back to the project with documentation, coding for the faps, and whatever else to give back to the project.

P.S. The esp32cam version of the Marauder app works much better than the Wifi-Devboard version IMO.

Response from Erwin Ried | March 19, 2024

Thank you very much for your enthusiastic review and for diving into the Deluxe Ultimate experience! 😂 Your collaboration is greatly appreciated. I've responded to you in the GitHub issue you wrote. Looking forward to more interactions!

Bought the kit and I really enjoy it

For FlippenHeimer -Geiger Counter for the Flipper Zero

In my younger days I worked in nuclear power as a engineer, so when I saw this I thought "let try it". It was easy to assemble and calibrate. I created a 3D printer enclosure for it making it fairly unique.

It works well, and is a not-usual addition to the flipper but the software is readily available. I am glad I bough it.

Response from Erwin Ried | Feb. 24, 2024

Happy that it was a good experience Nate! But I would not consider it "easy to assemble and calibrate" for most non-engineer people, maybe intermediate :)

Sven | Feb. 13, 2024

Love the product!

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

TLDR: I really like the board!

1. Shipping was really well packed and extremely safe for the board. Just see if there is a tax in your country since I was surprised in Austria that there was a small tax fee of 10ish eur. But, bureaucracy has to eat ;)
2. First time I had to flash new software on it and it worked like a charm with online tool. Great job!
3. I had only problems with the Xtreme Framework Marauder app since I have used the one under the wifi folder and not the one on GPIO (OFC it is my fault but... just fyi). I have to read the manual first, then shoot questions :D

Future plans:
1. I would love to have a 3d model for the whole case since I am afraid for that one small capacitor :')
2. Would be cool to see add-ons on top or behind board to connect gps module or sim slot. Just ideas for future.

I will play with the board a bit more and see if there is some good/bad remarks. If I don't update comment than everything is 10/10.

Response from Erwin Ried | Feb. 13, 2024

Nice review Sven, thanks for sharing.

1) you could protect this capacitor adding the pins for the io0 and gnd 😌, but yes, it would be nice a full case, the problem is to make it compatible with different configurations of modules and headers and v1, etc becomes very complex. I don't know exactly how many boards are in the world but at least two thousand, and all those little capacitors are still standing as far I know 😜

2) it is a great idea

Jack | Feb. 5, 2024

Wonderful

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

It was exactly what I was expecting. Great product and quick shipping. Make sure you follow the instructions to initialize it to flash the ESP. I forgot to RTFM...hah. All is working fantastic now.

Response from Erwin Ried | Feb. 5, 2024

Hehehe :) great advice, but I also need to improve the manuals, it is a bit confusing for many newcomers

Robert | Jan. 28, 2024

Great product, high quality, fast shipping

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

I've already recommended to friends and my son (security analyst) and will continue to do so. Only thing it needs is a solid case.

Response from Erwin Ried | Feb. 5, 2024

😁 nice! About the case: yes, but it is also difficult to make it compatible with all the boards, that is why is a little "naked" protection now, just to protect the critical parts

Excellent David!

Beytullah | Jan. 3, 2024

Quite successful

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Everything is exactly as described, very successful, thank you. I struggled a lot for the demonic portal at first, but I finally figured it out. Although it may seem easier at first to use Evil Portal for a standard WifiDevboard, it was actually not difficult to do this for Mayhem. I was very pleased. I ordered from Turkey, it arrived in 2 weeks, I paid 11.21 USD customs duty. The seller showed a good price of 35 USD, but it could have been shown a little lower, but that's okay, thank you very much.

Response from Erwin Ried | Jan. 22, 2024

Demonic Portal sounds even better! hehehe :) thanks for sharing the transit time to Turkey with others

Rohan | Dec. 24, 2023

Received a faulty product

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

I tried everything still getting "Failed to initialize. Try resetting your device or holding the BOOT button while selecting your serial port."
tried the jumper wire, reset, changed the com port etc. everything, sometimes the flash light starts blinking automatically.
is there any way to return?

Response from Erwin Ried | Dec. 24, 2023

Hi. If is faulty you can easily get a refund or replacement contacting me via messages in tindie. However, I recommend you to check the video how to upload the firmware, it might be complicated the first time because you need to bridge the IO0 and GND pins together (while you reset it) with a piece of wire or something similar, this is to enter the firmware upload mode.

Tyler | Dec. 19, 2023

Purchase came as ordered

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

I am very happy With Edwin and the product he provided - I am purchased from other people here on Tindie and th tiem never showed up at all.

I live in canada and there were no issues with the shipping or the tracking at all at any time.

Thank you

Response from Erwin Ried | Dec. 22, 2023

Thanks Tyler! But lame that my kit is the only one you ever received from tindie :/

Stephen | Nov. 25, 2023

Kit and support are awesome

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Purchased the kit (and T-shirt) the kit took ages to arrive (Australia) and I was concerned but got a prompt reply from Erwin it was coming and waited. In the mean time I looked at the video instructions re soldering and assembly and it was excellent. All the tips and tricks were provided to get first rate assembly, first time. I pre printed the jig parts and case/protection parts so I was ready to go. I have since purchased additional CC1101 modules (with SMA antenna) and the NRF24L01 (SMA antenna) modules to populate the kit and the spare boards. At is stage I've got the most value out of the CC1101 module to extend distance with external antenna but the ESP 32 CAM has some interesting functionality and is great to demo the Mayhem board to people who may not "get" the other functions.

Response from Erwin Ried | Dec. 22, 2023

The package had no rush, just cruising down under :) thanks for the comments Stephen

Gabriel | Oct. 21, 2023

Not for the faint hearted

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Got the product in my hands in the UK around 1 week after I ordered it (no priority post or anything like that). Packaging was excellent, NRF24 and CC1101 worked out of the box. There was a slight issue with the ESP32 and it required me to flash the latest version (it was running Marauder 10 instead of 12 which actually has EvilPortal functionality). Fortunately there's .bins provided by the maker available online and you can use any web flasher to fix this. You also have to compile your own Mayhem apps and use them for controlling the ESP32 as the baud rate for the Marauder fork that is flashed by default is different than the vanilla one.

TLDR: amazing product and you get INSANE value for the money.

Response from Erwin Ried | Oct. 21, 2023

Apologies for the ESP32 hiccup Gabriel; but delighted you value the board 😇

Awesomesauce!!!

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Perfectly what i wanted at a great price! Fast shipping and wonderful packaging! Some may think this board is too much, but it's like a turbocharged pre-built board sooooo this is the Porsche of dev boards. Quality build!

Thanks for sharing Joseph, nice review to read while exploring Italy on holidays 🇮🇹🍝🤌

Jonasz | Oct. 11, 2023

it`s complete - yet complex.. not my thing (sorry)

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

I bought this module because of it seemed convenient having all-in-one.
The seller offers good craftmanship that is put together. What I personally thought was disappointing is the handling afterwards:

I own a standard WifiDevboard and still prefer using that one for merauder and EvilPortal.
Then again I realised the camera module is quite useless (IMO°)

I was super excited but once I started using it I maybe had expectations that were too high.

- firmware flashing -> still not been able to do it with the webupdate, offered in the instructions
- the apps in Xtreme firmware combine the Evil Portal with Merauder app, while the standard app seems more intiutive (select html etc)
- watch out if you order for abroad (I had to pay 87€ on toip of the silver pack because there was no receipt or purchase bill - in the box...°)
- would be nice if the case would also protect more of the front from the board

Don`t take it personally Erwin, thanks for tha handling: just doesnt work as smooth as expected
(maybe in the future work on a firmware flashing method like the ESP flashert or something...)

So it`s just not for me, I`m considering a switch to a different all-in-one module..
one that does not rely on custom made MAYHEM apps

Response from Erwin Ried | Oct. 11, 2023

I understand Jonasz, I know it is not for everyone. I dont know if you noticed that the board is just a ESP32, so you DONT really need to use my apps, you could compile marauder and use the official apps, or even run anything on the ESP 🧐 it could be your favorite board maybe that way.

Also, bad that you got that extra fee in the post office, there in no VAT integration/prepaid on Tindie, but I guess it is around the normal percent of customs duties for your country. I try to make it smooth, but this is out of my control.

Randy | Oct. 1, 2023

Great Product

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Took a chance on purchasing for all the combined functionality and does not disappoint. Build quality is great and everything came quick. I did have issues with repeat failures during the install, but it finally grabbed and installed with no problems. There were a couple minor issues in the software modules, but those were caused by me, lol, and fixed. Would buy from him again!

Response from Erwin Ried | Oct. 11, 2023

Thanks Randy! Awesome that you solved the install issue

Great Service

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

I recently purchased the Mayhem board for my flipper, and I couldn't be happier. The service was outstanding, with incredibly fast shipping from Norway to the UK. The board arrived securely packaged, ensuring it was in perfect condition upon arrival. Highly recommended for anyone in need of quality flipper parts and exceptional service! :)

Response from Erwin Ried | Sept. 30, 2023

Cool Bartlomiej! Hope you continue enjoying the board. In case you "need" 😂 Mayhem v2, here is a 5% off code that last until 30/oct/2023: OFFCINCO

Great product, new version, great assembly.

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

This showed up pretty quick from Europe (I'm in the US) and it was assembled very well. I went with the pre-assembled option based on previous mishaps where I try to solder myself. The seller was responsive with an update to the order (I had accidentally got the fully loaded package (that actually cost more) instead of the header installed version I paid for. The seller promptly sent me the board with the headers installed the next day along with a complimentary sd card! The kicker was that he did so without asking for me to send back the fully loaded (more expensive version) that was accidentally sent in the first place. So I ended up with two for the price of one, and I think he deserves a 5 star review.

PS: I wouldn't try to pull the same claim just because I got away with it ;)

Response from Erwin Ried | Sept. 21, 2023

Heheh, thanks Josh. Yes, in this case when it is my mistake I guess is bad/good luck to get a replacement :) but I try my best not to do mistakes 🥲

Great board, expanding Flipper to lot more features and apps

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

The MayhemV2 arrived pretty quickly, well packaged, works great!
The initial set up took me some time as the webinstaller installation failed for me like for many others, what eventually worked for me was
1. Update to latest Unleash FW first
2. Then connect Mayhem with the GPIO to the Flipper and to my PC with USB
3. continue with the rest of the instructions from there (don't skip the shorting the GND and IO0 step !)

Response from Erwin Ried | Aug. 29, 2023

Thanks for sharing Dor! BTW, Xtreme firmware now includes the Mayhem apps bundled, so that's the only thing I would change from your tip 😁

I have some issues with flashing the firmware on devboard.
I was with unlished 056 and web installer does not work.
Trying to open usb port via cmd doesn`t help.
Then I put extreme firmware to my flipper, USB com port was changed from com6 to com8,
and then web installer transfer FW to my DevBoard.
10x Erwin :)

Very Happy

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

Amazing Flipper Addon.
Pros:
Greatly increases funtionality of the device
Board came in protective packaging
Quality Design
Great communication from seller

Cons:
None

Note: I did have some issue with the board when it arrived and asked Erwin (seller) for assistance, he got back to quickly and we managed to solve the Issue within 24 hours.

The Issue: The issue I was having was that the board was not being detected properly but it turned out that I hadn't insterted the board fully into the Flipper GPIO slot. It might require you to wiggle it in to the slot.

10/10 would buy another one.

Response from Erwin Ried | July 5, 2023

Hei Damien ;) good tip for everyone: just be sure is fully connected
