I flew the ATTiny tx this morning in my Buzz Bomb modified to use a 9g servo instead of the Ace magnetic actuator - great range & solid feel but alas the linearity has deteriorated to a point where the stick assembly is unusable 😩. There is a dead spot & a significant "jump" in servo travel in one direction, not so bad in the other direction. Back to the drawing board :oops:

I have two D&R single axis sticks that I purchased from Ace years ago. If I can get my 3D printer working correctly, I'm thinking of trying to emulate them but modified to use a conventional pot. Added to the list......
Cheers,

Wayne

Old 27mhz model car radios are a good source of single-axis sticks...

I've just had some forced 'down time' while recovering from some minor surgery. Rather then be bored or waste away watching the idiot box, I put the time to good use by making another 1+1 Tx :) .

For this version, I turned the case on it's side, my thinking being 2-fold:
1. I can comfortably hold the Tx in my left hand with my left thumb over the throttle button while launching, then hold the Tx with both hands while flying --> pseudo Mode 2 - right thumb steers while left thumb controls the throttle.
2. its a little different :P

The case is a bland neutral coloured cheap plastic job off 'the bay'. Since it has a shallow recess on the front, I inserted red stick-on auto vinyl in the recess after painting the case black. This colour combination reminds me of a 7ch Micron Tx I have tucked away in a box in storage. I used a D&R stick with a separate D&R trim pot. The encoder is Phil's ATtiny 1+1 Mk2
1+1 Tx #2

Rather than use an internal Frsky module as is my normal practice, this Tx has a plug in Multi-Module (from Banggood), operating a FlySky Rx.

over-spray from painting the case exterior makes the internals look worse than they really do ;-)

This is my first ATtiny 1+1 Tx retro-fitted with a D&R stick. Works a treat!

All in all, a 'recovery' day well spent :D

Looks fantastic Wayne, I like the inlaid vinyl idea. Where are the 'D&R' sticks from?

You realise a genuine Flysky RM002 module is only £14? :D

Thanks Phil :D

The sticks and trims came from Ace. I bought a lot of Tx hardware, pcb's & servo mechanics from them back in the late 70's & early 80's. They were always great to deal with.

Yes, I'm a long way from Yorkshire :shock: but there is some ancestry to keep me in check :D
Since Flysky run two software versions, I have more series B RX's than series A, so I bought a 003 module for them. The multi-module doesn't 'talk' series B, but it does talk FlySky series A + Frsky + Walkera to service my eclectic collection of early 2.4G RX's. :P

Thanks for the code, the Tiny version works really well & the boards are cheap - simplze ;)
Cheers,

Wayne

The throttle button, the momentary buttons I have, have 3 pins, one side opens when pressed, the other side closed when pressed.

Which way please?
