Due the Trump tariffs there are some restrictions to US: tracked shipping is more expensive, express tracked letter will be used for those cases

About

Hi! I’m a computer engineer from Chile, now living in Norway. I enjoy 3D printers, cheeseburgers, HP calculators, robots, and South Park.

I usually spend Saturday mornings on this hobby, assembling boards, updating firmware, and 3D printing.

Shipping Policies

If you choose "Prepare my delivery NOW!" I will speed up preparation, but shipping time stays the same. Normally, preparation takes 1–2 weeks since this is just a hobby.

Untracked packages are usually reliable but can sometimes take up to 6 weeks. Estimated delivery times are: Europe 1–4 weeks, Asia 3–6 weeks, US/Canada 2–5 weeks, other regions 2–6 weeks depending on distance from Norway.

Packages are dropped off at the post office the next business day after shipping. Weekend packages may be held until Monday.

If the address is wrong or the package is not picked up, it may be returned. I can resend it for a new fee. Tracked returns may cost about $35 USD.

Handmade items cannot be returned. Most parts are documented and open-source for self-assembly. No warranty on self-assembled kits. Fully assembled units are tested before shipping. Manufacturing defects are covered for 90 days from delivery.

To cancel or change an order, contact me immediately. Orders take time to assemble, and some work may already be in progress.

Good build

For FlippenHeimer -Geiger Counter for the Flipper Zero

I bought the pre-built device. Works great, attaches great (don't have to remove the flipper silicone protector) and I'm very happy with it. Thanks!

flipperheimer

For FlippenHeimer -Geiger Counter for the Flipper Zero

This is a great product, a must-have for the Flipper Zero. However, I have some improvements to suggest: I recommend adding a control knob to adjust the buzzer power. Additionally, on mine, if you tap it slightly, you hear a ping.

The overall service was great, with quick responses, and the package was double-packed, so the sensor was not damaged when it arrived. However, the shipment experience was less good, with a lot of delays.

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.

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.

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.
