DIY: CC1101 Module for Flipper Zero

Your Flipper Zero comes with an internal CC1101 module for SubGhz functionality, but if you want to increase the range, you can build an external module quite easily.

The CC1101 module I used above cost around USD3, and the AMS1117 5v to 3.3v step down power supply buck is around USD0.5. You will also need some male and female headers, prototype board and wires. You can find all these parts in Amazon, Aliexpress, etc.

There are several different CC1101 modules, so please refer to this page for the wiring schematics for the module you are using. The only difference with my design is that I am using an AMS1117 step down power supply buck to convert Flipper Zero 5v to 3.3v so that this module can be smaller since everything sits over the GPIO 1-8 of Flipper Zero, and it also makes this module hot swappable.

My wiring connections and modules are as follows:

First, we cut the prototype board and headers to the required size.

Next, we solder the male and female headers, and the AMS1117 module in place and connect them accordingly. It would be a good idea to use a multimeter to double check that you have all the connections wired correctly and nothing is accidentally touching each other when they shouldn’t.

Now we can insert the CC1101 module and connect it to Flipper Zero, and run some tests. Open SubGHz > Radio Settings > Module and select “External”. Now you can use it like how you normally use the SubGhz functions.

That’s it! Now we can move on to designing a case for this. I used TinkerCAD and printed it on my Snapmaker 2. My 3D files are over here, but you might need to modify it to your needs.

Here is the final result.

Hope you found this tutorial useful. Happy making!

3 weeks ago my dryer stopped working.

I watched repair tutorials, looked up reddit threads of common issues, I got out my dad's multimeter and measured all the electrical parts I could reach inside after removing panels!

I finally ordered 2 parts off ebay and replaced them.

Dryer works!

Except now it makes a low humming noise when plugged in but not actively running.

And is warm like the heating element isn't shutting off when the switch is set to off.

So it DRIES clothes, which is what we want.

But in order to not burn my house down, I flip the breaker off after using the dryer. Which is working for now.

Except I really want to go to bed, it's past midnight, and my load of jeans still isn't dry after 1 cycle so I put it on longer and I have to stay up to flip the breaker when the clothes finally dry.

Surgery On A Game Gear #1

I decided recently to start blogging the stuff I do as like a diary in order to keep track of the stuff I do. I can't always make YouTube videos on my interests because posting too frequently is bad for a channel. But also because my interests don't always make for good videos. I bought a Game Gear a few years ago and I finally decided to try and fix it. I found a soldering iron and multimeter in my apartment left behind by the prior tenants. They're both functioning still. I looked up a bunch of tutorials for all kinds of repairs on gaming hardware in addition to working on game gears. It seems like this might be easier than I thought, I previously worked in tech on iPhone, Tablet, & Laptop repair. Mostly as diagnosis so I have some useful experience already.

Turns out a lot of video game repairs tend to be pretty easy things, polarizer replacements for Wonderswans, Capacitor replacement for Game Gears, and things like that. Seems like every major console has 1 major failure point and fixing that lets them live up to another couple of decades. Thanks to Ceramic Capacitors made for the Game Gear replacing the electrolytic capacitors with them means capacitors that will never need to be changed again. Awesome. So currently I'm awaiting on the arrival of a ceramic capacitor kit which should be here Tuesday. I heard this is a harder replacement than electrolytic capacitors but ceramic is cheaper and better. Besides, I heard you can't really mess up a device beyond repair with solder. You can always remelt, clean, and try again. So I have the opportunity for plenty of practice.

Above is a picture of the inside of my actual Game Gear. I'm not 100% sure if it's a capacitor issue because the interior is surprising clean and the screens randomly fail on these. I've seen a lot of videos where the electrolytic capacitors were leaking. That's because inside of them is a liquid. Since these fail frequently I'll be replacing them anyway. But it's weird to me that they aren't leaking. If replacment fixes it I'll be replacing only the shell to a custom one, if it doesn't fix them then I'll need to buy a screen replacement which costs around 70 USD.

You're probably wondering where the capacitors are. If you've seen a capacitor before they look like little batteries with legs. I marked them in the red circles in the picture above. The capacitors inside a game gear are encased in a black plastic housing. They might have done this because they knew the capacitors would be an issue and the plastic was to prevent leakage or maybe it was just extra protecting. But after nearly 30 years this plastic has become very brittle and isn't protecting anything. Weirdly they also glued them down and the plastic has begun to fuse to the board. So removing them means sometimes the plastic will break leaving bits of glued plastic to the board. These will then have to be melted off with a soldering iron. Thankfully I only had a couple like that.

I'm guessing my game gear was lightly used, which makes sense as it only came with 4 games. I got it from an older woman selling off some old video game stuff to a local games store. I also picked up an Atari 2600 and about 30 games from her.

Removing them is pretty easy, first I used forceps to lift them. If they were stubborn I used flush cutters to lift them. I tried to avoid using the flush cutters as they might snip the plastic housing. On the bottol left one you can see a bit got stuck to the board. You can leave the plastic, it won't get in the way of a ceramic capacitor because they're much smaller. The ceramic capacitor won't need to be bent to lay down.

After lifting removal is easy. You use forceps to hold the capacitor then push the soldering iron against the solder to melt it. This will free the capacitor's little metal legs and it'll come right off. I had my iron set to 400 Celsius if someone sees this and tries it in the future. For removing the plastic I used a wedge tip and gently rubbed the area until the plastic was gone.

Overall, this was a pretty easy thing to do. But once the ceramic capacitors come in I'll have to put those in and this a little bit smaller and don't have legs. I've heard it's a pretty challenging solder and I've only soldered once before and that was 2 days ago to fix the contacts on a Genesis' power port. But if this is the majority of what I'll be doing in repairing these old devices then I think I can handle it. I've already ordered some extra dead gaming devices, Wonderswans, to repair. Hopefully I can increase the number of working retro electronics in the world. It'd be a shame to see these go in a dump where they can't be played.

I'll see you all again in a few days when the capacitors come in. Hopefully this all turns out well so I can get that custom case. I'll eventually replace the screen regardless as the screens are pretty bad but I'd like to avoid having to drop 130 usd on both at once. When a damaged Wonderswan goes for 10 bucks that money could be better spent fixing those.

DIY: ESP32 Cam + ESP8266 Combo Flipper Zero Module

Here is my project for this weekend, a Flipper Zero module with both ESP32 CAM and ESP8266 D1 Mini combined. This allows me to use it for Marauder, Deauther, WiFi Scanner, Camera, Morse Flash, etc. in a single module. I did consider doing a Mayhem board with NRF24/CC1101, but I find myself rarely using them and Flipper has CC1101 built in anyway (just with shorter range).

The steps to build it is relatively simple. It just combines the two separate modules and some switches to switch between between the two. Below is a quick guide on how I build it. Note that this is not meant to be a detailed step by step tutorial. If you have some experience with building electronic projects, you should be able to follow along.

Build Steps

Start by cutting the prototype board to the required size and the header pins to the correct lengths (8 & 10 pins). Adjust the position of the plastic thingy holding the male header pins, then bend the pins.

After that, we solder all the header pins to the prototype board and also start soldering the required wires. See the references at the end of this post for all the wiring you need to do to connect the necessary pins.

I used four DPDT switches to switch between the 2 modules. All the required connections from Flipper goes to the switches, then from the 2 poles of the switches to the 2 modules. The same with the antenna as well, as I didn’t want to have 2 separate antennas.

Now is a good time to use a multimeter to check all the connections are good and that there no shorts.

Lastly, we use hot glue to hold the antenna cables securely to the prototype board. Here’s what the completed module looks like.

Now we just need to attach the antennas and insert the ESP32 Cam and ESP8266 modules. Oh, and if you have not mod your D1 Mini to use an external antenna, read this. Flash all the required firmware and test!

Next project, designing and 3D printing a case for this module.
