K.E.E.B - I'm finally prepared to show my hardware mod

[Holyvision]

Too sweet! I'd buy one!....lol

I'd buy one too

Might look into the TI Tiva-C Connected Launchpad. It's programmable in Energia (Arduino IDE clone), has 256kB of RAM (yes, RAM), 1MB code storage, a 120MHz ARM CPU, a bunch of input/output headers, built in Ethernet, and costs $20 free shipping.

I love Arduinos, but I'm completely addicted to the absurd amount of power in the Tiva-C launchpads.

I'm finding the Arduino Leonardo out of stock, but they do have a Arduino UNO starter kit that includes USB, does this look like it will work or be worth the cost ($80)? Likewise, should I get this book?

The Uno won't work for this because it doesn't have the extra hardware needed to emulate a USB keyboard. I believe the Leonardo is the only one of the genuine Arduinos that can do this, although some of the clone boards probably can as well. That book is a perfectly fine introduction, although it doesn't really have any thing that you can't find online. Only buy it if you want something to read on the train or in bed, when you are away fom your PC.

Thats dedication for you +10 points to you Sir !

=)

Nice to see stuff like this, truly.

Could you add a higher resolution picture of the right-hand side of your KEEB to the gallery? I am especially curious how you configured the rotary switches, especially for the MechJeb part

[MalfunctionM1Ke]

Love it

[katateochi]

very nicely made, I too would buy one!

[goldenpeach]

well done!

I guess you have to be proud of yourself after a whole year of development!

[Geneborg]

Nice one, this deserves some attention

[combat squirrel]

AMAZING, love it

[EladDv]

Where can i get one?

Sorry to take so long to reply. I've added another pic to show the rotary switches more clearly. The lefthand one switches between different flight modes, which changes the key mappings for WASDQE and IJKLHN, as well as the information displayed on the LCD. The righthand rotary is used to select the mode for the MechJeb auto attitude function. The dial positions are Prograde, Normal, Radial, Target, Target velocity & Target parallel. The blue Pro and Retro buttons set which way round you face along that axis. So for example, to point prograde, you turn the dial to PRO and press the blue PRO button. To point anti-normal, you turn the dial to NML and press the blue RETRO button, and so on. The green button ignores the dial completely and just points to the current manoeuvre node, and the red button cancels the auto-attitude system altogether, so that you can steer with the joysticks again.

Wow. Really amazing work. Hats off to you, my friend.

[Richy teh space man]

Dear Santa..

Seriously though, that is awesome.

Read the article in Linux Format a few months ago, was a good read.

Issue 187 for anyone interested.

[Trann]

Where can I download this?

[Moesly_Armlis]

So very cool. But it needs more cowbell, defiantly more cowbell.

Thanks for the pictures, a wonderful source of inspiration

The electronics is built around an Arduino Leonardo and four SX1509 I/O expander boards. Power is supplied by an external 5v supply module. The case is made from an MDF shell with 3mm aluminium sheet for the exterior.

My attempt is only at its "Let me display apoapsis and periapsis with 7-segment-displays" phase, but I will need some input elements soon... I really have to look into expander boards to get the amazingly insane amount of inputs your board has

Nice work! Are you using analog joysticks for flight control? I'm thinking of building my own controller and I'm not sure what joystick to go with. For RCS translation I think a digital one will be enough. Another option would be to use a digital joystick for flight control and a button to switch from normal to fine control movements.

EDIT: Read your post again and saw that you use digital joysticks. Maybe it's enough, I use the keyboard at the moment and digital control works fine there.
