Using a Raspberry Pi, Pi IR camera, touch LCD and a few other items of tech, Ebin Philip has built an Ophthalmoscope for under $400, allowing eyes to be scanned for retinal diseases.

The portable device aids the discovery of Diabetic Retinopathy, with units averaging $10,000 - $25,000 if purchased.

Discovering Diabetic Retinopathy early can aid in the prevention of blindness in diabetics, with the increase of the condition increasing year on year.
Diabetic Retinopathy is a complication of diabetes causing damage to the retina, eventually leading to blindness. The cost of state of the art retinal imaging devices required for identifying this disorder lies in the range $10,000 - $25,000. This makes them inaccessible for the population in rural areas or developing countries. We aim to develop a device under $400 which can provide reasonable quality retinal images to clinicians.

Achievement unlocked ! Bike power upgraded!

Also 25 euros of "discarded" wood + plexiglass is awesome !

Hi folks ! trying to choose between
7805 regulator vs https://www.pololu.com/product/2850 to provide 5V power for usb devices & sensors from a 12V solar setup (don't have a ton of power to spare)
- this is meant to run 24/7
- the price is obviously way higher for the Pololu (ten fold)
- but the Pololu can provide more than twice the current
- and the efficency of the Pololu is WAY higher than the 7805
- the 7805 will likely need a heatsink, and will waste a non trivial amount of power on ...heat

Thanks in advance!
This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. High efficiencies are maintained at light loads by dynamically changing the switchi...

I am with +Thomas Sanladerer​, I never use linear regulators when the voltage drop is high. For small voltage drop I use LDOs like the MCP1702 family (e.g. 5v to 3v3). Else switching supplies (12v+ to 5 or 3v) are still dirt cheap and they are no heaters like the 78xx.
They are said to be noisier, but I have yet to find a case where they impacted me (and I should check with a scope by myself to see how well filtering caps do their job).

+Alberto Valero Gomez  I will put BOM /docs online when it is done : perhaps simply into a git repo on Github?

btw these were all made "analog" no digital drawings or anything, but it would beg for a parametric design (based on locally available wooden parts) , I am just too damn lazy for OpenScad , sorry :(

FAIL !! And kids , this is why you MEASURE what you want to put into a box before buying it....

It's not about black v white. (This is the media narrative trying to start a race war.) It's about police not being held accountable. Facts are that when accounting for crime rate, etc; black people aren't killed disproportionately to white people by American cops. The problem is that cops are never held responsible for their fuckups. They always put the cop on 6 months PAID leave, go "Well, we investigated ourselves, and found ourselves not guilty!" and then put them back on the force with no actual punishment.

Crap that is a lot of death & pain over the span of just a few days..

But sadly not surprising: apparently the guy had psychological issues, was suicidal etc ... horrible but sad.
Before the onslaught of hateful reactions please consider this :
what kind of impact all these have
- having to leave a war torn country (that country was your HOME, for better or worse, your friends and family always were there etc)
- possibly having seen the death of your family and friends
- facing the hardships of getting to Europe (if you don't drown or otherwise get killed in the process)
- getting to a different country , where they speak a language you do not understand, where you are hated just because you are a foreigner/refugee, where you are isolated and lost
- then get told you need to go back

Are any of you claiming you would not have snapped at any of those points? I honestly don't think I would be able to survive even the first few ordeals.
It does not excuse anything, does not make the death go away, it is just the sad reality, these are HUMANS just like you or me, so before you go and side with the racists , try to picture yourself, or your friends , or your children going through all this ...
More hate and 'closing borders' mentality will not solve ANY of it.

Like +Arthur Wolf, I like discussing ideas and believe that the world is a better place by listening to ideas that I may not agree with and then presenting my point of view. When someones point of view is validly argued, I do regularly change my mind on things. Saying that I won't ever change my mind is historically inaccurate based on all of the things that I've changed my mind on before. Like Arthur, I'm about as far left as you can get without being a lunatic. I believe that everyone should have equal opportunities, I'll be voting for Jill Stein this upcoming election cycle, I believe in universal healthcare, freedom of speech, freedom of religion, etc. But I cannot turn a blind eye to an ideology which a large portion of the world shares which is homophobic, anti-woman, anti-freedom, anti-speech.

Don't get me wrong - I'm not offended, enraged, or any other similar word. I'm merely here discussing a viewpoint and pointing out failures in your presentation of that viewpoint.

Getting mad and telling people to "just not reply" is extremely close minded. If you're that afraid of discussing your viewpoint, that means somewhere deep down you know there is something wrong with it.

Teaser for new Star Trek series
https://www.youtube.com/watch?v=QGsuM31IC-Q

So ermm meeeh ? Bad CGI, fugly ship design, verbatim reuse of old concept art to base the ship design on (see Star Trek Phase 2) ...still curious !

I am amazed, I was not aware of all the things you could do with a wood router until a few days ago (I have no shame in admiting but feel bummed about my ignorance).
Just incredible ! I have been watching a ton of videos about routers, all their uses, how to build a router table etc

Given the amount of manual work it would save me / increase in quality, I might save up to buy a Festool one, since they seem to be top notch
(some of the Bosh ones are quite ok, but nearby shops only sell lower end ones)

it's the RT0700CX4 I got BTW -- the 'model number' is a bit irrelevant tho, as it' changes depending on the 'package' you buy -- base model is RT07 tho)

Well Mark I don't think you would do /heavy/ jobs with it out of the box, but many people make props and alternative bases for doing that. For example you can find online a pretty cool wide plex mount that adds a lot of stability while still allowing you to see what you are doing...
