Hello, I decided to rebuild mine 22w amplifier that I burned (had no radiator 😀 so the TDA just fried)
The main pieces you need:
R1 – 39 kΩ
C1, C2 – 10 µF × 25 V (electrolyte)
C3 – 100 µF × 25 V (electrolyte)
C4 – 47 µF × 25 V (electrolyte)
C5 – 0,1 µF × 25 V (ceramic)
C6 – 2200 µF × 25 V (electrolyte)
U1 – Microscheme TDA1554
Input power: 6–18 V.
The blueprints:
Here is the beginning:
I mounted the radiator (not permanently) and the TDA
White and chocolate sponges with fresh whipped cream+soft cheese+mandarines+poppy seeds.  Decorations: chocolate, sugar paste flowers and sprinkles.
Honey cake with fresh whipped cream. Ready to roll icing decorations.
Hello,
I made some improvements. The first one is the look. I painted the led lines white so that the organic glass wouldn’t be transparent and show the LED’s
Second improvement is the back of the speaker. I turned the amplifier and reduces the wires. Now there is only two wires that you need, the power one and the input one. the LED use the same power wire. Also I can turn the LED whenever I want just by plunging the wire in or out and this does not affect the amp.
Hello,
Yesterday I flown RF with the new servos and prop. I have to admit that it flies very nicely! But I still manages to brake the prop somehow
Hello,
This is kinda of topic but I think worth to show.
few years ago I had a Dobson telescope 1200/20
Unfortunately I sold it to get a bigger one, but it got complicated so I lost it for now…
To have a telescope was one of my dreams.
When I had it I was mad for looking at the sky (as I am now, but a bit less)
In winter when there was minus 20 Celsius and strong wind, I still climbed on the roof to see the sky.
Then I started photographing it. I took some photos of the moon as a first attempt.
The feeling of watching it is outstanding! And I managed to take some photos!!!!
Then I thought of filming the sky… This was different…
I wish I will manage to buy a new telescope in some years and continue this pleasure…
Finishing the model.
Servo changed to Emax Es08A,
Prop changed to 6×4 non flexible
Covered the wing:
White and chocolate sponges with fresh whipped cream+soft cheese+mandarines+poppy seeds. Chocolate fondant and fresh whipped cream decorations.
Hi,
So waiting for a new servo I decided to make my plane even more detailed and beautiful also realistic.
I made the letters from the covering film by simply drawing and cutting them. Then I applied them to the plane as usual for this type of material by using an iron. Looks good don’t you think?
Hello,
In my second flight with the RF-4 wasn’t that successful as I had expected, but I didn’t damaged it 🙂
The left aileron servo got stuck. This is the second servo that failed me, towerPro SG90
