Scientific R&D At Home?
An anonymous reader writes "I'm currently on the cusp of getting myself a new hobby and making some investments. There are a few areas that interest me greatly, from playing with EEG/ECG and trying to put together a DIY sleep lab, to astronomy, etc. I'm somewhat hesitant to get into these fields because (despite the potentially short-lived enjoyment factor) I'm not convinced they are areas that would lend themselves to making new discoveries in the home and with home equipment, which is what I'd really like to do. I've also read quite a number of articles on 'bio hacking,' and the subject seems interesting, but it also seems futile without an expensive lab (not to mention years of experience). What R&D hobbies do Slashdotters have that provide them with opportunities to make interesting discoveries and potentially chart new territory in the home? Do such hobbies exist?"
Sorry, home science is now an arrestable offense.
In the late 1980s I worked for a biomedical company (BMSI) in Silicon Valley that made EEG equipment. They stored the EEG waveforms on a video tape. The image on the video tape had the EEG waveforms from 16 head sensors on the left of the screen and an image of the patient on the right. Patients would try to get 100% disability checks for life by claiming to be epileptic. They would spend a night in a monitored sleep lab, and then do a little horizontal dance while pretending to be asleep. Our equipment matched the brainwave recording to the image of the patient twitching to verify or disprove nocturnal epilepsy.
It doesn't really matter that you can or can't do real high-level research at home on DIY equipment. It only matters that you can build calibrated and reliable medical equipment that delivers accurate results at a small fraction of the cost of the equipment used in American hospitals. As we all know, the US medical health care system is collapsing. The recent legal reforms are basically meaningless and consist mostly of administrative and billing changes. If you can do a $1500 sleep apnea test or overnight EEG recording on DIY equipment for $50, then you are a welcome and honored member of the new health care system that is self-generating now underneath the bloated, corrupt, and crumbling official health care system.
Just be discreet at the present time.
By the way, instead of digitizing and storing the EEG waveforms directly, do a FFT on 1024 samples. The EEG waveform is basically sinusoidal so it can be recreated mathematically. Determine the formula that will regenerate the recorded waveform sample, and only store the offsets and co-efficients of the sine wave formula that will recreate that segment of the waveform accurately. You will get a 1000-to-1 data compression and be able to get all the circuitry into a hand-held small package.
