Taniwha Flight Computer Home Page

NOTE (2001): I still have no kits and probably wont have any any time soon - the DAC is no longer easily available - we need to lay out a new board for a more modern part

New Software available - I'm releasing the free compiler I've been working on for the past year it's a simplified language intended for relative non-programmers but with a C subset sort of tacked on top - it's intended to be ported to other people's flight computers (if they'll have it) so please encourage any other vendors you know of to get in touch

NOTE (July 24th 1998): I have a small number (6) of bare boards available - contact me before you send in an order so I don't overcommit. The price has unfortunately gone up to $15 (my cost).

Nasa's dropping a few 8051s on Mars next year

NEWS: New ROM released (V2.3/V2.3A) it includes support for larger (8kx8) EEPROMs and some bug fixes to Basic

NEWS: New ROM released (V2.2) it includes EEPROM support - and the ability to boot the computer from EEPROM

NOTE (Dec 6th): A note about a board bug you should fix

In case you have stumbled onto this page (or if you were surfing and washed up here) it describes a small cheapo flight computer designed to be flown in a high-power (or model) rocket - more information about which can be found here.

This page is designed to be a home for the Taniwha Flight Computer which I'm building and kitting for a number of other interested people. This is NOT a for-profit enterprise - the idea is to get a critical mass of people up and using the same hardware so that they can write cool and interesting code (or make cool and interesting hardware) and share it with everyone else who's using the design.

A quick note about copyrights etc - all the stuff here is marked with my copyright - this is something I do with everything I design to retain control of my designs should I decide to sell them for profit in the future. However everything in these pages, the design itself and the software that runs on it (at least the stuff I provide) is hereby provided it for anyone's use - but I retain ownership and copyright (even feel free to build them commercially if you want).

"Open Source" is now all the rage - we've been running this project that way for the past 4 years - so as always "feel free to steal anything on these web pages".

The version 1.0 of the flight computer documentation is still available here. The V2.0 version of the kit is described below - changes are marked with (*).

The basic computer can be considered to be roughly equivalent to an Apple II in memory and power - features are:

Here is the current version of the V2.0 assembly instructions, and here, here and here are the schematics.

I have started a sources page containing the sources for then assembler and monitor/ROM.

The kits consist of 5 things which I will be selling at cost (I'm sure someone can find the parts cheaper - these are the prices I've been able to come up with for small runs without me chasing bits all over the valley) - a first time buyer should normally buy a parts kit ($33) and an RS232 kit ($6):

What DON'T you get - the kits are only for the base computer - they don't include the A/D converter, ADXL50 or EEPROM or associated capacitors or resistors - the idea here is to get the basic price down as low as possible. I will be publishing where you can buy the bits, the ADXL50 in particular is almost as expensive as the whole rest of the board. This is NOT a working altimeter out of the box (or baggy) you need to add sensors, A/D converters and programming - there's a list of commercially available rocketry altimeters here.

I will hold all checks and not cash any untill I ship people kits.

"Taniwha" is pronounced tun-e-far and you wouldn't want to meet one on a dark night.
