Filter board for RadioBerry Transceiver.

 

Instead of making a pcb I handwired the filterboard on an ArduinoUno development pcb.

Connectors for PTT-out, LP-filter switching. BP-filter switching and a 2*10 connector to RadioBerry.

Next : Interface for SWR, PA current, PA temperature and power out.

 RadioBerry 100W transceiver development.

I have used a HermesLite and a Hardrock50 amplifier. The SDR-software I like most is Quisk. Quisk is easy to set up both on Linux or Windows. 

My transceiver is not located the same building as my computer. It was easier to install a 25m network cable than a coax cable.

Restarting blogging

 Long time since I have updated this blog but here I am again. Now I will blog a little about my ham-radio adventure.

Vertex Nano Status

I may say that my Vertex Nano 3D printer has been a real workhorse during the last 6 months.

The Nano has been used for nearly all my prints that fits inside the printing area of the Nano.

Materials I have successfully sent through the printer:
PLA
PETG
MoldLay
3DE Ceramic

I have replaced the BuildTak surface with ordinary (much cheaper) blue tape.

Plans for the near future is to replace the hot-end with an E3D-hotend because I need to print some small parts using a 0.25mm nozzle.

Have fun.

Great success!

Today I printed a Marvin Keychain.

Left Marvin is from today's print with the new cooling fan and the right Marvin is printed one of the first days with the Vertex Nano printer.

The prints is made with the same gcode file sliced with Simplify3D.
Material PLA, print speed 40mm/sek, layer thickness 0.2mm, temperature 195deg.C, no support.

No touchup has been made on either of the Marvins!

The cooling fan is now published on thingiverse as:

Happy printing

Modifying firmware for the fan.

I have modified two files in Vertex-Nano-Firmware-master for controlling the cooling fan with standard M106 G-code.

File 1: Marlin-main.cpp
Find the function "set_led_brightness"
// Set led brightness according to current variable
void set_led_brightness()
{
   analogWrite(7, map(vertexLedBrightness, 0, 100, 0, 255));
}

and then just put a comment before the AnalogWrite statement:

void set_led_brightness()
{
// analogWrite(7, map(vertexLedBrightness, 0, 100, 0, 255));
}

File 2: pins_K8600.h

Change
#define FAN_PIN 8

to
#define FAN_PIN 7

And then compile  and upload to board. I used Arduino IDE ver 1.8.1

The LED can be connected to the 12V pin located near the connector for the internal fan.

Have fun

Cooling Fan (Revision 2)

Revision 2 Top view

From bottom

One screw holds it all.

Assembled

And in place

A few modifications to the firmware has to be done before testing but I don't have time during the next few days .-(

Have fun
