A few people have asked to be put into contact with others making Elizas and Daffodils at home. I’m told that a forum is just the thing to allow this to happen.
So the redlightsonthebrain forum has been set up. It is set up as a free site, so apologies in advance for any advertisements.
I’m the Admin, but I’m a novice forum-user, so anything could happen….oh well, we can only give it a try. If it is a disaster, it can be removed from existence.
Life is full of revelations. In my case, this revelation is a slow realisation of the blatantly obvious.
I’ve been fretting over the instructions for a two-wavelength Eliza. These instructions will involve soldering and flash stuff like that. It’s OK for those who solder for pleasure, and who are at one with the finer points of electrical connections, but most Eliza-makers are happy to avoid unnecessary complications.
So, applying the KISS (keep it simple, stupid), I offer this pronouncement:
Make two Elizas (or Daffodils), one with the ~670nm LED strip and the other with a longer wavelength. While 810nm is the fashionable one, it has been difficult to get, whereas 850nm is much easier to find.
Then use the two light hats in sequence, one immediately following the other. I tend to use the ~670nm first, then the longer wavelength second. I’m not sure that it makes much difference which goes first, as long as one quickly follows the other.
I’ve had a few queries about using high powered LEDs, the logic being that if low powered LED strips can improve the health of neurons, then lots of low powered LEDs or high powered LEDs will do a better job. If only it were that simple…
Prof John Mitrofanis and others have shown very clearly that there is a Goldilocks Effect. They use a more scientific term, but it is the same thing.
1. Too little red/near-infrared light doesn’t do very much at all.
2. Too much red/near-infrared light can cause problems for the neurons.
3. The just-right amount of red/near-infrared light is perfect.
Prof John and his team have been able to define the “just-right” dose at the neuronal level in mice. But we have no such knowledge for humans. So we have to be cautious. Very cautious.
So, please don’t use high powered LEDs. Start at a low level of red light exposure, as we have done.
Remember that we are at the very beginning of understanding of trans-cranial lights. There continues to be wonderful research work being done and as it appears, I’ll let you know if and how this changes the approach to DIY light hats.
What I do know at this stage is: Less Is More.
It is wonderful to hear about more Eliza light hats being made out of buckets. Those buckets sure are useful things.
I’ve heard from two people who are using plant pots. I did try using plant pots early on in my experiments, but the ones I bought had sloped or curved sides and I found it difficult to secure the LED strip without contorting it into a place it didn’t really want to be. However, others have been more successful, which is wonderful.
I had serious discussions with the first person to create a light hat from a plant pot.The topic was the appropriate name for the plant-pot-based light hat.
It clearly could not be Eliza because there was no bucket involved.
We agreed on Daffodil.

Congratulations to the maker of this very fine Eliza!
It is heartening to hear of more Eliza light hats being made at home.
For those who are apprehensive, take heart. It can be done. If you aren’t in a position to do the fiddly stuff yourself, then you will almost certainly have a mate who is prepared to help. Just ask.
Thanks to Trish and Toby for this brilliant find.
Autobarn have a windscreen sun shield for sale. The brand is Streetwise, it has silver on both sides, it is folded concertina-like around 600mm by 140mm and opens out, giving a good expanse of foil fabric to cut up.
It cost $5. Perfect!
From the makers of the first Eliza…
“tell timid people that if we at our ages can make one, 80 and 89, they can too.”
The stunning bucket comes from the Reject Shop. It was tougher plastic than the buckets I used from Chickenfeed Discount Store, and needed a hacksaw to do the final cut.
This Eliza is very very beautiful.
Max, eat your heart out!
