They are sold out at this time. I have more parts already on the way for the next set of 25.

I am also reworking a few things on the board for better labeling and footprints and will order more boards once the next 25 sell.

Not sure on a time frame as one of the parts is coming from Europe but am hopeful for end next week.

I picked up 3, and I really only need two initially.
I will ship one to you once it arrives.
Will just send you a paypal invoice when it gets here.
oberman.l@... will be the request, what paypal can I use for you
when I ship.
Will be $20 (I got three assembled) as that was the price for each,
plus I guess about 2 bucks USPS if you in USA

I registered on the site to see a manual.  Couldn't download anything because "my basket was empty".  Could you send a manual so I can look it over?  Thanks, Dale

As long as I make enough to put food on the table and keep getting parts/boards I am happy. This helps a lot of people get gear and kits at a affordable rate, it also allows those that can't build a little help too.

Can I teach you how to make the connection to the sound card and let you add that to the kit, because you could save the “assembled” buyers a ton of trouble for doing that for them.  The part is only five dollars, and the labor to make the connection is only about five minutes, but it will take the average person 20 or 30 minutes because they don’t know what they’re doing.  

If you take apart the $5 sound card, drill the case , solder make the connections, and put it back together, leaving the wires for them to solder to the board, you should sell that partially assembled section for $8 dollars at least, because you have made the kit buyers far better off—-then all they have to do is wire to their radio and it is ready to go!!!

Hi Joe,

Haven't seen any development on this board in some time.  I'm sure you've been busy.  Any chance there has been any progress on this?  I'd love to get the cad files for the board.

​I snapped up two of those before he runs out.......takes me 30 minutes to solder one togehter (including the sound dongle) and he just took off a good chunk of that!!!  


I'm going to find the boxes I use and post those here also.    And also the 500 ohm pot for those wanting a panel mount TX control.   The RX is set-and-forget

​I would suggest you get familiar with how to crack open a 1475, and how to solder to them, and offer the entire thing as an option also -- it is duck soup to do it when you know now, and you get your +5V out of it for free also --- and that is a significantly huge improvement over the effort others will have to do, in order tolearn how to make those connections.


it makes it way more reliable as well....but people may destroy one sound dongle before they get the hang of soldering the +5 wire to the tiny red line coming in from the computer.    i do it with ease now.

You are absollutley NUTS to offer it for $20   ASSEMBLED.   That is very little over what the  PARTS cost us.   

never again will I solder one together----I'm just ordering from YOU!!!! 


Because there is a ground plane, you may even get away with not enclosing this, but you'll do better if you just screw the board to a small piece of wood (or double-stick-tape to some cardboard) and put it in a small tea tin or something.   I found tin boxes for $2 each.


If you make the TX gain ccontrol a 500-ohm panel mount, you'll have much better control of the TX signal....  That's what i do for HF.  For VHF, the little trimmer works fine.   


i use the $5 Adafruit 1475 cound card, and I literally drill a hole and solder the wires to the right places, after I pop apart the white plastic, of course.   See here:   https://www.adafruit.com/product/1475​  They are not great soundcards,,,,but they work.

Re: Nextion with KA78T05

Lawrence Galea
 

When dropping down voltage I always use more than one regulator in series to split the dissipation.
E.g. 7809 or 7808 from the nominal 12V then to the 7805 and bolt them to the aluminium case or to a heat sink with thermal compound.
They are cheap enough not to bankrupt you.
Take care when buying from Ali etc

Maximum current draw for the 5" Nextion (backlight @ 100%) is 410mA 
Arduino Nano ~20mA
Si5351 (all outputs enabled) ~22mA

Assuming 13.8V input, there's over 4W of thermal power to be dissipated. As Allison already explained, whatever IC you'll use it'll need a heatsink.

Also, try to keep the heat away from the Si5351 oscillator crystal as it would generate frequency drift.

Check , raduino with nextion miight need 1amp odd. You cant work at 100% with input 12 or 13.5v.

If the 7805 input is just 3v above what you said is understandable.

Better try a genuine 78s05 it might manage. 
All the best

Why would you need another regulator ? The LM7805 is designed for 1A output and the 5" Nextion display + Raduino uses about 500mA (per specs).

You only need a heatsink for the LM7805.

This will be true for any other linear replacement you use (KA78T05 / 78S05 etc) as the dissipated power is the same.
