This one is really a great and neat job, because it fits perfectly with the old pcb board from the x0xb0x but, adding new controls on the surface.

I have many other projects at this time on my head, but surely I will finish this one soon, because it's a special thing, and I'm very happy now to learn how this mod works and how it does what it does.

Thanks to Brian Castro !!

PCB was created using the toner transfer method & press-n-peel blue transfer film.

Alesis ineko PCB. Just a few surface mount chips here, dwarfed by buttons, potentiometers and LEDs.

cooling off the etchant. dont mix it into hot water in a milk jug =)

PCB Agitator experiment. This project is not done just documenting the steps I took to get here.

here is one board, note some of the traces got partially etched.

also, the sharpie marker worked pretty well as etch resist. thats good!

I honestly didn't touch this up at all.

This one made explore!!

clean those burrs ;)

These are the PCBs for my design project (spectrum analyzer shirt)

Nice to see you too.

Close-up of the receiver. The main chip is the Nordic RF chip that also contains a microcontroller. The chip near the bind button is an EEPROM that holds bind information persistently.

On the right of the two ICs are two voltage regulators. The upper one is a 3.3V regulator that drives most of the logic, the lower one generates 2.5V needed for the Nordic chip.

Just below the servo connectors are four tiny protection resistors. We will de-solder the left most one to free up the signal pin on the battery connector. Stock this pin contains some form of test signal that is unfortunately not PPM but a sum of the three servo pulses.

Side note: The receiver consumes about 25mA at 5V. If the 3.3V regulator is able to accept 10V input voltage then one could power up this receiver directly from a speed controller that does not have a BEC, like most older Tamiya ones.

Alternatively one could replace the voltage regulator to ensure it can handle at least 10V.
