...an unpleasant experience.

For PICOZX motherboard for ZX Spectrum original case

I checked on two monitors, and it didn't work. I sent it back and it was a bit of a hassle to get my money back, but I finally received it. Unfortunately, the contact with the seller was not very pleasant, he does not use the language of a gentleman. But in the end, after an unpleasant experience, I received a refund and we will not see each other again.

Response from Bobricius | Sept. 11, 2024

Haha, scammer, that amused me. I think if I were a fraudster, I'd surely find an easier way to make money than spending hours soldering some circuit board and then dealing with dozens of emails for an month from someone who can't seem to connect a monitor properly.
So, to clarify for those not involved:

- I returned the money within a minute of the gentleman's request, even before I received the shipment back.

- I wanted to refund the shipping cost for the returned package as well, but since Tindie can't refund more than the customer paid, I asked for a PayPal address where I could send the shipping amount, but the gentleman didn't bother to respond.

- Subsequently, I received the package back and tested it on multiple monitors. It worked flawlessly on all of them, and I even sent the gentleman a photo, to which he also didn't respond.

- So I really don't understand why this guy is crying over 6.49 euros, which I'm more than willing to refund - I just need his PayPal address, but the gentleman has decided not to communicate.

WOW!

For PICOmputer - RP2040 Raspbbery PICO - QWERTY devkit

The picomuter is completely not what i expected. Its way nicer than expected i appreciate the craftsmanship thank you. Now only if i can find some sort of case for these 2 devices my network would be very close to complete.. Definitely recommend both of these products

Nice kit

For mini PiQWERTY USB wired mechanical thumb keyboard

I've made 3 of these now. They are a nice kit and handy little keyboard.

The documentation is a little confusing because there are links here to different websites with different versions of the keyboard with different software files.

Here are my additions to the documentation that I learned.

Though the PCB has several pads for other components you really only need the raspberry pico and the 37 tactile switches to let it work as a keyboard. It has space for the power switch but isnt needed either since it is on by default when plugged into the USB cable.

For the firmware the file I used was called "Armapad36v4-pico2023.ino.rpipico.uf2" linked above under "datasheet." To install, I plugged the new pico into my PC while holding down the "bootsel" button on the pico. This makes windows recognize the pico and open up a file explorer window to the pico. I then copied the above .uf2 file to that folder. The pico automatically installs it and reboots (all within 1 second) and is then ready to go as the keyboard. For those others like me who are new to this, you dont need Arduino IDE or circuitpython to get this kit running. Just drag and drop that .uf2 file!

I used M2x10mm screws and ~4mm nylon spacers to hold the top and bottom PCB's together.

the keyboard is automatically recognized and works with my windows PC and a couple raspberry pi projects.

The only issues I had were the pico not liking some of my USB cables. But that's of course not a problem with this kit. But if something does not seem to be working, try a different cable.

what a nice diy zx spectrum is this

For PICOZX - Handheld ZX Spectrum 128k + other 8bits

The quality of the pcb's are exceptional quality, the solder mask on the pcb helps a lot to locate which part needs to go.
i really enjoy the build! About the documentation, i give it a 3 star, since the url points to hackerspace website without any documentation.

overall im really happy with it!

Really nice, tiny and stylish Keyboard with a little extra

For mini PiQWERTY USB wired mechanical thumb keyboard

This Keyboard is really awesome. I mean its from Bob, and he always delivers fantastic pieces of technology. Its not my first buy from him, he really also deservers to be sponsored on patreon!

The Keyboard works as intended, soldering took about a hour. The links in the text could be updated imho.

- I was not able to flash it with arduino ide, but thats pretty sure on my side
- It took some time to finde the circuitpython file, as it is linked under "Datasheet". (If you are as blind as me this could help^^)

Would by again!

Falligan | Dec. 21, 2023

Master crafted works of art

For PICOmputer - RP2040 Raspbbery PICO - QWERTY devkit

I have the white pcb version which should be how the next generation of pico computers and lora messengers will look.

It looks very nice, but more importantly, it feels nice. The mechanical switches have very specific heights and pressure ratings. I think the maker probably gave this aspect of the devices a ton of thought. It never would have occured to me to use any other pressure rating than whatever the standard on most momentary switches are.

My version comes with a holder for the 18650 and he cleverly added a separate 18650 charging module inside the device. If you screw it up somehow its very easy to replace, they are are a dime a dozen on ali express and local electronics-hobby stores.

My 3.7v 18650 was all I needed, no separate charging circuit required, I just fired it up and the pico already has the zx spectrum tape emulation program running.

Highly recommend these devices.

Time to go install my zx spectrum games!

[Update]: An amazing tool for making your rpi400 standalone.

For Raspberry PI 400 cyberdeck / cyberdetox display

I had some trouble with the device at first and this is an updated review. The store owner, Peter, attempted to communicate with me sooner, but I seem to have missed his message. We recently corresponded and he was able to assist me in getting the device working. The codebase may be easier to work with now that the device itself is up and running.

This allows me to perform ARM development with ease, without having to invest in high-end ARM (M1 and similar) devices. The screen is small, of course, but I am accustom to working in restricted conditions and often find them pleasant to work within.

I'm very excited by the results now that it's set up and I'm looking forward to buying more of the handhelds available from Bobricus.

Thanks Peter!

Looks great!

For mini PiQWERTY USB wired mechanical thumb keyboard

I just ordered the PCBs and I have not assembled it yet but both PCBs look great! The layout looks really good and the size, despite being so small, The keyboard feels good Even with my rather large hands. Holding it reminds me of typing on a old school blackberry but it is a little bigger.

Tomas | Jan. 26, 2023

A work of Art

For PYCOBOY - Small universal console & computer

Not sure what to say, silk screen has all the required components marked out.
Everything fits together perfectly.
The option for larger more comfortable buttons on the main board is a great feature.
It is a very attractive design (New rectangle design).
Options for either through hole or smd on the vga resistors make it easy for people who use either.

Very impressed with both the product and the maker.
Thank you Bobricius!

Javier | Jan. 8, 2023

Zepir Raspberry Pi mini computer

For Zepir - Raspberry Pi Zero mini computer HAT

Extremely happy. Great communication with all of my questions answered. Description is clear and concise. Was promptly shipped and well packaged. As stated, it’s not plug and play and I knew this as I have experience in electronics and programming. My Raspberry Pi Zero W is waiting for this so it will be a nice project. There’s also plenty of documentation available by the seller, as well as a YouTube channel. I can’t wait to use this for projects and see what I can come up with. Thank-you very much Bobricias!

Perfect way to eliminate Coin Battery usage

For Coin cell battery emulator CR2016/CR2032

The item is perfect for what I needed it to do. I had to light up some LEDs and didn't want the hassle of buying multiple CR2032 batteries every time they ran out, so this has helped tremendously by having it plugged into a USB cable outlet. Now I can keep them on 24/7 without any issues. Also, The seller had very good communication too and the item arrived on time.

Would definitely recommend buying from them 👍

Fantastic Thumb Keyboard!

For mini PiQWERTY USB wired mechanical thumb keyboard

I just received my keyboard and it is amazing. The key switch pressure is perfect and the size of the keyboard is really really great. I tested it out with all the systems I have around here and it worked perfectly out of the box.

My full sized spare keyboard is now put away. This is just a bit bigger than a business card and keeping it on the spares shelf is great.

A few details about why I purchased it:

1) I work with a lot of virtual machines at my desk and sometimes need to work with additional desktop systems and micro form factor computers like Intel NUCs. Normal sized keyboards cannot be stored cleanly and take up too much space and most of the wireless off the shelf keyboards are NOT proper thumb oriented typing keyboards. The wireless keyboards are WAY WAY too large and using them tires out your hand because the key pressure is always far too high.

I thought this might be a great keyboard to use as a spare when doing installs, quick system configs and testing. I just recieved it, tested it out for about 15 minutes and it has already replaced my spare keyboard.

2) I have been looking for good examples of thumb keyboards as I have wanted to learn enough electronics to build a blackberry sized keyboard with my own layout. This is an AMAZING thumb keyboard. I am going to try and use it to see if I can get my thumb typing proficiency up to the levels I was on Blackberries.

What the creator this device managed to do, in my opinion, is make the keyboard the perfect size. It is just small enough to be perfect for thumb typing, the feel of the switches is excellent AND having the top pcb act as a cover PERFECTLY makes this thumb keyboard feel like a usable and quality product.

3) Lastly, if you look at the Bobricious line of keyboards and computers, they all have a quality design and finish to them. There is something very odd about his design aesthetic. He didn't just make a thumb keyboard to be purely functional, he spent time making it beautiful. First, he put a top pcb on the device and used the correct size switches with a nice feel that won't tire out your fingers. Then he select a unique black and gold type of layout, which is very nice. Then, on top of that, he added artistic touches like the Bobricious logo in a cursive font, the spock live long and prosper hand symbol (awesome, love the Trek reference) and just overal really lovely use of fonts, layout and led status lights.

I love works of art and I really think the designer brings something extra to even something as relatively simple as a usb thumb keyboard.

4) I may have to buy a second one and add it to my kit. On site visits sometimes mean I need to shuffle hardware and having a thumb keyboard for one off quick config / setups might be useful.

Anyway, just logged back in to share my experience of this product. If you are looking for a thumb keyboard with really good switch feel that wont tire out your fingers, you might consider looking into getting one.

Excellent product, plug and play!

For mini PiQWERTY USB wired mechanical thumb keyboard

Excellent quality, truly a unique product. I plugged this into a number of different computers and it is truly plug and play.

Eric | Nov. 11, 2021

Good product, code little bit hard

For PICOmputer - RP2040 Raspbbery PICO - QWERTY devkit

Board is very nice but docs with circuit python are not easy to find. I am a newbie with python. I am working on Bobricius ideas who writes programs with arduino ide rather than python.
I hope to reach the goal to create a Lora transceiver with circuit python. I will keep you informed soon.

Fills a need in the market - one of a kind

For mini PiQWERTY USB wired mechanical thumb keyboard

Great little keyboard - easy plug and play - looks like it will last a long time - sturdy construction. Would have preferred the USB out to come out from the side - but just a personal thing - at a pinch I could move it, but I won't. Currently using it with 5" touch-screen UMPC - Higole F1 - just not usually enough room on the screen for on-screen keyboard to be effective - this fills the gap in tech perfectly. Thanks Bobricus well done.
A final point - I wear glasses and the symbols embossed on the keyboard face are understandably tiny - really tiny - I struggled to work out what was what at first - but once you know it's not too hard.... it's clear as it can be given the space available - but for those with less than perfect eyesight you need to bear this in mind.

Alex | April 30, 2021

Great item, nicely done.

For Joule Thief SMD DC/DC white Led

These joule thieves are great. Very efficient way to save energy and to completely use up a cell. Great compact size too.

Even better than I thought!

For mini PiQWERTY USB wired mechanical thumb keyboard

I purchased the 49 key fully built.

Typing this review on the board now. Definitely a thing of beauty and well put together. Top workmanship!

The size of this thing is amazing, literally a shirt pocket sized full qwerty keyboard with mouse function too! I don't think that is made clear anywhere. Yes it is mouse and keyboard in one tiny unit! Pressing the *** buton enables mouse mode meaning the page up/down/left/right buttons move the cursor and you can even move diagonally. Madness!

Anyone who appreciates security or pen testers will appreciate the lack of wireless donggle/bluetooth. Wired only. Nice.

Cons: To be fair, not many. If Bobricius was spoiling us there would have been rubber button caps. Bearing in mind you won't be writing the Odyssey, this is no big issue. Buttons are responsive but it is difficult to type at full speed at least until muscle memory kicks in. A housing would have been a nice option but i think most people interested in this will have a solution.

It's as badass as it looks and that's very!

Get one!

An excellent product - for advanced devs...

For DiXi - arduino SAM ARM D11 USB stick

The Dixi I ordered 6 days ago arrived already today in France. I’m amazed by the small size and the functionality!

Why did I write “for advanced devs” ?
It’s not plug and play. If you want to use the Arduino IDE (which is still great for quick checks and hacks), you have to install the Arduino SAMD cores first, and then, after adding an URL found on GitHub to the preferences, the Mattairtech cores which unfortunately seem not longer to be maintained (last version looks like it is from 2018). The linked Mattairtech website is blank, which gives me a doubt about the future.

But if you are experienced and don’t need all that Arduino whistles and bells, you have a dev board with an excellent quality/price relationship.

Cute flashing jewelery

For Solar powered flashing LED small heart earrings

Got a few of these for my daughters for Christmas and they love them! They work just as they were described and I would definitely order again

Kayla | Dec. 14, 2020

Beautiful!

For mini PiQWERTY USB wired mechanical thumb keyboard

Starting with the obvious: the keyboard works just as expected, no issues at all.

Apart from that, it just looks absolutely beautiful! The gold-black combination makes it look really stylish and the font/icons used fit verly well. The only thing I find aesthetically non-fitting is the silk-screened board identifier from the manufacturer on the front. It might be worth placing that manually in a different place.

My only other suggestion would be to include a set of standoffs and screws. I happened to have a bunch of them, but not everybody might.

Shipping was a bit slow, but I'm attributing that to the current global situation.

Kirill | Nov. 27, 2020

These are just cute

For Solar flashing green diamond LED earrings, pendant

They are comfortably sized even for smaller heads, but not compatible with a muffler. Blinks in pretty shitty light conditions, and the PCB looks nice (I got B type).

Fantastic little keeb. Well worth the price!

For mini PiQWERTY USB wired mechanical thumb keyboard

So I'm a bit of a mechanical keyboard hoarder, and I happened to come across this gem, and just had to have it in the collection. It's fantastic for pairing with a Raspberry Pi for the occasional settings menu in RetroPie, and I've got some plans to cobble together a dedicated Pico8 Pi handheld loosely modeled after the PocketChip (but now with better keys!), for on the go game coding. Doesn't take up any space, and it's got the good microswitches, so "typing" on it isn't half bad. It takes about a week for the keymap to become muscle memory, but after that, it's very easy to blind thumbtype on it. It doesn't have all the usual keys you'd expect to find on a normal keyboard, but that's okay if you're just typing a bunch of text. You don't need modifiers apart from the shift key for most work.

Besides a dedicated handheld keyboard, there's ofcourse a miriad of applications that this little keeb is good for. It's size does lend itself to just chucking it in a backpack, and you'll find a use for it on-the-go ;)

10/10 Highly satisfied with my purchase!

(ps: this was typed ON the keyboard)
