Radioberry preamp board where to buy?

[Tech Minds]

Hi all,

I have just discovered the Radioberry, coming from a HL2 device, and I would like to know where I can purchase the Radioberry preamp board from?

Any help appreciated!

Thanks

Hi Matt

Tnx for your interest.

The radioberry development started in august 2015 (https://groups.google.com/g/hermes-lite/c/3xXRlskdkOw/m/7afQwTMKAwAJ) ; i found the initial proposal in the HL group .

I have a preamp board available.

Iam asking 60 euro ex shipment. (estimate shipment costs 18 euro)

Hi Johan,

Like Matt, I too would be interested in a preamp board if you happen to have another one available? I reckon if someone like makerfabs were to manufacture them they would sell like hot cakes.

I can be reached at 2m0...@nsamail.uk if you happen to have one you are willing to sell.

Thanks in advance.

Sorry Bryan,

The 10 boards assembled by makerfabs  are gone.

Iam not organizing a group buy .

The information to build one is available at: https://github.com/pa3gsb/Radioberry-2.x/tree/master/hardware/preamp/release/beta1

Stay safe! and have fun.

Johan,

I am organizing a group buy thru maker fabs. However they are asking me if i have permission to build this.
Is it ok with you if i build 20 of these and sell them at cost + shipping to the interested parties? Ever since Matts video a renewed interest has taken shape. I would like to facilitate this if i may.

Micah,

If you get a makerfabs group buy, I would like one.

If Makerfabs is following this thread to judge interest in doing a Radioberry preamp build, count me in for one.

In addition to a Radioberry board for my Pi 4, I have two Makerfabs built Hermes Lite 2's, and they both work great.

Hi Micah,

Very good initiative. No problem in doing a group buy.

Please be aware in the communcication with Makerfab:

https://github.com/pa3gsb/Radioberry-2.x/tree/master/hardware/preamp/release/beta1/bom

I sent a BOM.pdf and an excellsheet.

Be aware that Makerfabs uses the excellsheet; but this sheet does contain all the components.

Please look at the DNI do not install or do not assemble:

The following components must not be installed for the others there is no restriction:

C320 + C323

R305 + R308

R214+R215

C301

The wire on the core ; makefab wants to use red/black and white colored wire!

Have fun.

Johan,

Wonderful! thank you! :) I am waiting for a reply from maker fabs, and i forwarded this on to them. They wanted to make sure i was authorized, haha i told them it was open hardware!!! :) But still, I am glad you have given the green light to proceed! I did not know this "do not assemble information, this is invaluable stuff. I upped the order to 30 units seeing as im getting good feedback from not only the youtube video, but also this forum as well.

Johan,

Unfortunately, I have reached a snag with Makerfabs, and the group buy. They are saying they dont know where to find the latest files and what version to use.

I have forwarded on the links to them that you gave me, however they are saying that they cant find the files for the latest and greatest version. Could you please provide some clarity? I feel like i am going around in circles with them. Maybe you could reach out if you dont mind.

I ask for a quote for the Radioberry 2.0 hat as well, to see if we could do better then the alibaba price so i would appeciate any info on that as well.

I am still trying to get quotes for everybody!

Here are the links i sent to Makerfabs, is this correct? Im not sure whats causing the confusion., if these are the latest versions, then game on! 

[pa3gsb]

Micah,

Please do not send a github link to makerfabs....

Communication is essential when speaking with makerfab! 

They have to be certain about the design files/boms and so on... i agree fully with makerfabs to decline a link to a github!

 For instance the radioberry_preamp.zip file will be accepted but I strongly advise to read a previous mail about pdf and excell sheet.... otherwise you are getting boards with components assembled which are marked as DNI.

Johan,

I see the pdf and the xls file in the BOM folder. I also see the DNI list at the bottom of the files. Is this the only caveat? 

I hope im understanding this correctly: As long as they read the DNI note at the bottom of the page, then all is well?

https://github.com/pa3gsb/Radioberry-2.x/blob/master/hardware/preamp/release/beta1/bom/Radioberry_preamp.pdf 

Also as far as the Radioberry is concerned, is beta 5 the best option to get quoted?

Would you recommend, next time, instead of forwarding links, is it better for me to download the files from github and send them to Makerfabs via email attachment?

I appreciate your patience Johan! :)

Thank you, 

Micah

  Hi Micah,

No problem... i like to help.

>>Be aware that Makerfabs uses the excellsheet; but this sheet does contain all the components.

Please be as precise as possible... you need to modify the excell (make a pull request ; i will merge the change to keep it all consistent)

Do not think it is described somewhere in a corner of a document;  they will read or have to read..... 

the same is valid for you... i have warned with the first sentence quoted from the earlier post (i do not want to sound harsh (engilish is not mine native language) but like to emphasize... what can go wrong will go wrong)

Yes a quote for the radioberry beta 5 is ok... please the same is valid for both!

Hope this helps

Hi Micah,

Do not assume that an assembly house will acquire and use the correct files from just a web URL link.  Instead, send them only exactly the files you want them to use for the build.  Assume that the files you send are a legal document, checksum those documents to ensure they have the same documents that you do, and preserve your document set accordingly.  Do not assume that any DNI or other comments will be applied.  Instead send them a modified BOM and build instructions with only the components that you want purchased and installed, and no others. etc.  You may also need to create and send them instructions on how to test the built assemblies before shipping them.

Ron

Johan,

I am having trouble with the pull request.

is there an email address that i could contact you at?

I have modified the spreadsheet on google sheets, as you requested.

I will forward this modified BOM to Makerfabs

Thank you,

 Johan,

A journey indeed!  No worries, we will figure it out together! :)

This isnt my first rodeo, but im not used to getting bucked this much! I guess this is professional league. haha

Unfortunately we have hit another snag:

Hi Micah,

I am working on this project, and there are a few questions would like to confirm with you.

preamp  beta 1  

1.   FB101,FB102,FB201  MPZ1608S601ATA00 out of stock, please confirm if there is an alternative part no.

2.  T302  MABAES0060 out of stock now, but Mouser shows there will have a new batch stock on 27th Oct 2021

3.  U101  ST1S10PHR out of stock, please confirm if there is an alternative part no.

 Radioberry 2.X  beta5

From the ibom there are some components do not have the part no. , the PDF BOM in beta5  show beta 4, so please confirm the part no. and send me the BOM.

Thank you!

Best regards

this is the most recent response i have gotten from Makerfabs, "oh the joys of chip shortage!" :/

I was wondering if there are any written instructions on how to wrap the toroid? 

The pictures can tell us a lot, but it is hard to see the exact number of turns for each color of wire.

As far as testing is concerned, are they supposed to do testing in house before they ship the units?

If so what testing regiment should i require?

For my own testing i was going to procure one of the radioberrys on AIibaba and just hook it up, run it through the paces.

I would like to send them a zip file with all of the exact information, as you and others on this forum have recommended.

If i was to do it correctly i would send the following:

1. PCB-Gerber files

2. Scheme- schematic, pdf

3. BOM- the updated BOM which i have edited, the xls spreadsheet

4. Note - Info on wrapping the toroid and any other non-standard info for assembly, text

5. Pictures - of the unit that you have sent me

6. Testing Regiment requirements, QC etc, text

is this complete?

Thank you,

Micah

[Young Monk]

PS

7. Position- position files front and back

[Young Monk]

Can anyone recommend replacements for these parts?

[Young Monk]

Johan,

I am having problems with the group buy. I am just like everyone else here, I just wanted a preamp, without which it doesn't do much good to have your radioberry board!

It has turned into quite the ordeal just to order the board!

I really like your radioberry board, and i would like to have the whole system, and do some testing. Next i want to build the amp (5 or 10w).

Please advise me on what to do next!

Makerfabs is saying that they need a recommendation for 3 replacement parts. Is this something we can work around?

Are these parts easily replaceable?

Thank you,

MIcah

Micah,

I do like to support anyone building a radioberry and or a radioberry preamp.

Also willing to help with small things to get a group buy working.... but the time i do have left for the hobby i like to spend for my own projects.

The component shortage is not helping.... but i think with all the knowledge (and willingness)  in the group it must be possible get it going.

If a amplifier is what you looking for; there are some alternatives as described in:

http://www.pa3gsb.nl/2021/03/23/radioberry-tx-amplifiers/

So as said my involment will be so little as possible.

Have fun with the radio hobby.
