My favorite kind of device!

For Tinyriser - a better Lenovo Tiny PC riser

Product works, no complaints. I appreciate the handwritten note as well! Tested and working in an m720q, I look forward to putting it in an m920x.

Thanks

For Framework Mainboard Power Button Shim

All is well. Thanks for designing and being willing to sale them. I will say that the tracking did not update untill the day it was delievered. This is likely due to the internation shipping and the changing hands of the package amoung shipping companies. Also, the package was very small. I could see the package getting lost in the mail. Thanks again.

Great little addon for Tiny 920

For Tinyriser - a better Lenovo Tiny PC riser

This is exactly as listed, and fitted perfectly in my 920. I was able to put in a QNAP WM2-2P2G2T into the PCIe slot, a 1TB 2230 drive into the M.2 slot with no fitment issues at all even with a WiFi card installed on the motherboard. With the 2 built in M.2 slots, now my 920 has 5 m.2 slots for storage, nice!

The Tinyriser does need a little support on the side if you do not want it wobbling, I used some double sided gel tape, it fit the gap perfectly and everything is nice and stable with it. Quality of the part is great, and it just plugs into the PC and works.

FairywrenTech packed and shipped out the Tinyriser within a day of ordering, and it arrived in a few days from the EU to the USA so no complaints there. I was notified by the seller when it was shipped out, and had a nice handwritten note inside. Thanks for the creative part, and I will keep looking at your shop for any new parts that will work for me!

amazing USB-C altmode dev board!

For Altmode Friend - a module for your USB-C PD needs

Extremely useful for learning about USB-C alternate modes, and i have quite a few projects that this will pair perfectly with! thank you so much for everything you do for open source hardware and helping me and others learn :)

Great Product, Seamless Process

For Framework Mainboard Power Button Shim

I bought this item and thanks to great communication from both the seller and the platform, it was an effortless and easy process. For international shipping, i was ecstatic to see that it would only be 2 weeks and 15USD. Great product too! it works as advertised and is well labeled on board.

Lovely bit of kit, this!

For SD card locker (make true read-only SD/MicroSD)

I do a lot of "hey, you know computers, what's wrong with my X" repairs for family and friends. I've had a Kanguru read-only hardware switch USB stick for over a decade now but it's getting long in the tooth being only 8GB and replacing them is, £50, £60 minimum for one.
For half the price *or less*, being able to toggle *almost any SD card* to be used for the same secure-from-virus shenanigans? Beautiful. I looked at the original project and making it myself was daunting - I thoroughly appreciate it being available to purchase! 10/10, highly recommended.

Edit with an update:
While using my original a defective cable (micro-usb retaining clip was bent straight up, didn't notice it at the time - bad eyesight) broke the micro-usb port off. I considered this no fault of Arya so I ordered a more expensive version with the battery capability included so that if it happened again there would be a redundant way to power it without very precariously holding the port in place (which did work btw!).
I let them know what happened just because I figured they'd be curious that it finally did (they stated on their page that they reinforced the soldering because it had happened in testing but that no customer had reported it).

My replacement arrived today. Not only did they include the USB C port on the battery version (I did not pay for this part), they sent me a USB-C and micro-usb version as a replacement for my broken one at no request from myself! I am incredibly happy with the customer service. When you're a small seller sometimes things mess up, especially when you're relying on international postage (the royal mail held this package for like 5 days with no updates), but they saw a problem that was absolutely not their fault and they still felt the desire to "make it right", in a sense. If I could add more stars to my review, I would.

Already locked and unlocked multiple microSD cards with all three of the lockers I have. One is important in my home security setup and two have different "IT Technician" tool loadouts for installing, diagnosing, repairing, all that guff. I want to reiterate that USB sticks designed for this purpose *start* at the cost of the most expensive version of this device, for a single USB stick, at 16GB. I've absolutely gotten my money's worth.

works perfectly

For SD card locker (make true read-only SD/MicroSD)

This SD card locker is easy to operate and works perfectly.
The case does have a sharp edge near the usb plug, but nothing a few seconds with a file can't fix.

Jeremy | Feb. 5, 2023

Great product, friendly seller with great communication

For uSDlocker (make true read-only MicroSD)

Handy little device. Well built and well thought out usability interface. Seller was very friendly with great communication and prompt shipping! Would definitely buy again from this store.

Warren | Oct. 28, 2022

Works perfect, easy to use

For uSDlocker (make true read-only MicroSD)

Very handy device. Works perfect. Simple and easy to use to lock and unlock microsd cards. An especially useful feature is that the instructions, the "how to use this", is printed right on the device pcb board itself, meaning you will always be able to find the instructions. Can't beat that!

A well-made adapter that fills a niche, at a bargain price!

For M.2 B-key to M-key adapter

It's not just laptops that have B-key M.2/NGFF slots - some of the very latest ultra-low-power embedded, IoT, and server motherboards from Supermicro and Mitac also have B-key rather than M-key slots. I suppose there's a market niche still using B-key m.2 SATA SSDs in 2022, but an NVME SSD runs rings around them even when limited to two PCIe 3.0 lanes - and B+M key NVME SSDs are basically unobtanium. These adapters (with a bit of physical modification to support a longer drive) let me use fast commodity M-key m.2 NVME SSDs in my new Elkhart Lake low-power edge servers. A bargain! Thanks!

Just works & abundundant accessories

For Mini PCI-E breakout

This board just works and is great to interface boards like BG95-M3 MiniPCIe with enough power (many Chinese boards from AliExpress or Amazon fail here!). Plus easy access to all the relevant pins and a lot of additional accessories like antennas in the package. Exactly built as requested with fast delivery - thanks a lot.

Cool little sd locker. Works as advertised.

For SD card locker (make true read-only SD/MicroSD)

This thing is really cool. Our business sells digital products on sd cards, and by locking them we can prevent users from accidentally deleting their files. Good work!

Fantastic Product!

For SD card locker (make true read-only SD/MicroSD)

I always wanted to make my raspberry pi projects "appliance grade". For me, appliance grade means the OS will be impervious to power outages. I configured the micro SD card as a read-only OS. However, I do not assume that a read-only OS cannot be broken into by a virus and made writeable. Therefore, I wanted additional assurance that the micro SD card could also survive virus attacks. The SD card locker creates another level of security because it operates external to the OS and closer to the hardware level. If the raspberry pi OS is compromised in any way, then a power cycle will return it to normal. Other uses will be for long term critical backup and offline storage.

I LOVE IT when someone makes a super-useful gizmo like this!

THANK YOU!!!

You want one of these in your arsenal

For SD card locker (make true read-only SD/MicroSD)

When I was debating on getting this, I really could not find a reason to need it. Well, my curiosity got the best of me and I decided that I wanted it anyway. The time it took for it to make it to my house was faster than some pieces of mail I send across the city (and this was coming from Latvia).

I have not really put it through its paces as of yet, but the instructions that came with it are clear and unambiguous. They flow very well and make sense. I have locked one of my older cards and it will now Rickroll people from now until the Big Crunch at the end of the Universe.

If you come across the same dilemma I had on deciding if I needed this or just wanted this, trust me, you need this. I am able to lockdown my MicroSD card that contains vital information. Such info that I cannot have it deleted and needed a backup to a backup that was firmly in place. DVD would not work due to size considerations.

Overall, the seller is making items that you cannot simply purchase. Toss the maker/seller some love and buy their stuff so they can make more stuff we will need.

Cheers!!

works great and instructions for usage are clear

For SD card locker (make true read-only SD/MicroSD)

Using this to lock SD-cards that contains keys for startup decryption of pcs (FDE), so people that have them don't get the idea to use them for anything else.

The locking and unlocking works perfectly and instructions are very clear. I did not try the permanent locking function, since that is not required in my use case.

The addition on having the instructions on the PCB is also very good since, If I don't use this for some years (which will probably happen) after the initial use I would probably not even remember what it is, and for sure not how to use it. Having the instructions right on there, you will never lose them.

Board looks clean and I can't find any fault with the solder connections.

I shipment happened very fast and I got a clear message with the tracking information. Packaging was good, the components were even sealed in esd-shielding bags, didn't really expect that.

If you order the adapter for reprogramming you get a SD-cards adapter that has wires soldered to it, that you than can plug onto the pins of your AVR programmer, I didn't test the reprogramming yet through.
It would maybe be a good idea to just put an SPI header onto the board, maybe that could be an improvement for further versions. But since it has none currently the solution of using the SD-card slot as SPI header is actually quite nice.

Ordering this here saved me a lot of time (and possibly money) by not making me acquire pcbs and all the different components to build it myself. Since the (very few) other commercial solutions that I found are way to expensive.

Amazing Product

For SD card locker (make true read-only SD/MicroSD)

The Micro add-on is definitely worth it as it removes the requirement to carry around the Micro to SD card adapters.

Great idea is the instructions is apart of the PCB.

The device is useful if you have files that you want someone to have but don't trust them if they are going to delete them off the SD card then you can temporarily lock them.

Amazing SD card locker!

For SD card locker (make true read-only SD/MicroSD)

I ordered two of these SD-card lockers, and twiddled my thumbs for a few days until the package with the devices arrived.

I immediately connected one to a micro USB for power, and tested them on a micro SD card.
That micro SD card now has a song called 'Starlight' on it, until the end of its life.

The documentation of how it works is on the back of the device. You can't miss it, can't lose it.
The product itself is small and easy to transport.
A flashy sticker on the top side makes it easy to spot, but it's likely a good idea to keep that micro USB cable attached so you don't lose it.

The seller communicated clearly when the product was ready for shipping, and sent me a tracking code which greatly enhanced the precision of my anticipation.

Absolutely nobody you know has this device.
It is cheap, does what it needs to do well, and helps any company or mission that wants to distribute information in a non-networked way.
It's Christmas soon, just saying.

Response from FairywrenTech | Nov. 6, 2019
Hey! Thank you for your review! A small correction - at the moment, the documentation for locker use isn't actually printed on the back of the device, instead, it's printed on a leaflet that I put inside the package. However, to think of it, having it printed on the back of the locker itself (both on the PCB and on the bottom of the case) is a great idea! I'm ordering a batch of new, improved, SD locker PCBs now and will be building about 20pcs of these, and now it seems I also will be ordering documentation stickers I'll be putting on the bottom of the case.

Also, I don't think you should keep the locker with the cable plugged in (if that's what you meant by 'attached'). If you push a MicroUSB plug upwards/downwards with force while it's inserted into the locker, you might stress the MicroUSB port and have it eventually break off the PCB, rendering the locker unusable until the port is re-soldered - at the moment, you need to disassemble the case for that, so it's a hassle you'll want to avoid. I've noticed this problem a week ago when using these same MicroUSB ports on another product of mine - the next revision will have either a reinforced MicroUSB port or some kind of reinforcement built into the case. If you (or anybody else that's purchased a locker of this revision) have this problem, let me know your address (use the arsenijs at zerophone dot org email) and I will send a replacement locker at no cost.

Cheers!

Very satisfied.

For SD card locker (make true read-only SD/MicroSD)

A battery powered SD Card locker for setting the write protection flag in a SD Card or, with adapter in mini SD Card or micro SD card.
Perfect communication and perfect delivery. Thank you very much!

Very useful device, and easy ordering experience

For USB power друг

This was exactly what I was looking for to control an external USB-powered device attached to an embedded system where the system needs to be able to restart it from time to time, prior to this it required manually unplugging the device on each restart. The ordering process was simple, good communications with the developer, and it arrived quickly and was very well packaged.
