steps towards industrial design

Could anyone test the even distribution of power from a PIC based white noise generator? It would be great to hear from somebody with an audio workshop....

More generally I am very interested in joining forces with one or two embedded engineers (possibly around the world communicating by email type platforms) to build industrial experience

So far I have been completing a number of PIC and 68HC11 based embedded projects programming in C and assembler. Although I find these chips a bit limited and would be interested in working on other platforms too. I have built on experience as an electronics grad in the Sound and instrumentation industry to give familiar themes (signal generators, professional Peak meters, function generators, combination locks, bit streaming D to A converter) a bit of a twist( for example especially eliminating precision rectifiers and other associated hardware). I am building a portfolio of chips that contain these programs that I will advertise on my website, I have got quite a long way (eg working and tested programs) with 6 or so designs already, although as to how to market these (if there is a market!) I have no idea (are there any people that already supply such devices that can make any suggestions?).

Regarding how I would fit into such a community, I suppose it would be great to get some of my designs built into prototypes and tested and receive constructive criticism. I would be very happy to do (myself) for others, some code monkey donkey work, to muddle my animal analogies a bit (writing small bits of code, developing sub-assembly building blocks, testing software etc, researching and testing analogue interface designs). I am especially interested in projects with "real world" objectives (e.g. diesel engine control) or educational, scientific, democratic or ecological objectives. There would have to be a fair way of distributing any profits fame and adulation (don't hold your breath!) but I for one don't get too hung up on this - my local job just about pays the rent and I would be happy just to gain industrial experience in a more friendly context than..um ....industry. (I am also interested - but would have even more to learn about - DSP platforms). Also Are there any (perhaps college based) microcontroller clubs that any one knows of?

I would love to hear from anyone about the specific question or with related requirements, experiences or suggestions about the more general ones. Steve - South London, snipped-for-privacy@primex.co.uk

Stephen, You seem like someone who could help out here...I have a 68HC711 and am trying everything to write to the on board EEPROM. While I'm an accomplished C programmer, I'm new at the 68HC711 and have to get something going. Got any examples I could use.

On your quest to get involved in the Industrial Process Control market, I may be able to help you out there....I've been around a bit, like all over the world (Hibernia, UK, Sahara, India, Ghana, UAE, Argentina) as a Control SYstems startup engineer on multi million $ projects. This was based on my long background in Control Systems Software Development and Field Engineering. I have been (and still am) involved in numerous industrial product developments with micro controller based solutions. I have a few ideas of what is practical and what concepts will be marketable and how to implement them in small micros. At the moment I am intrigued by the TI MSP430 as it comes in a very small (4mm square) SMT package and is immensly powerful, low power, and low cost. I have a development system at home and found them to be very easy to work with ....worth trying. I just haven't managed to persuade anyone to use them yet. If you are interested maybe we could get something going. I'm in canada.

In the meantime, I sure would appreciate it if you would lead me to anything that can help me meet my immediate challenge of getting this old 68HC711E9 to actually work ....and write to its EEPROM.

I have decent equipment, but nothing that would do that easily. However, depending on the bandwidth and degree of precision you need, you might consider: - recording the white noise (with a flat-response mike, e.g. a good-quality electret, and a good sound card) into a PC, and running the resulting .wav through some signal analysis code. Cooledit (etc) has some spectrum analysis facilities (including, IIRC, power). - brute force approach: acquire/build a VCF with a sharp Q, and sweep it while measuring the results on e.g. a scope. You'll need to do some maths to convert amplitude to power.

I'm intrigued. I'm an electronics product designer, mostly working in embedded hardware/software (mostly bare-metal), largely in process control & comms (also audio). I'm on the South Coast of the UK. Not exactly sure what you're after - but if a part-time mentor is of any use, I suspect I'd enjoy it.
