Hello folks! Today I published a new post about open-source hardware for healthcare applications. In this article, I review the different platforms available for open-source hardware healthcare development. Enjoy!
When you think about healthcare, the first thing that comes to mind is a doctor with a stethoscope hanging around his or her neck. The first advice you get from your friends whenever you mention yo...

Ciao e ben ritrovato sul blog "Aspettando il bus". Oggi approfitto di alcune email ricevute, che riguardavano l'uso del nunchuk con Arduino UNO R3, per parlare dei circuiti alimentati a 3,3 volt. In rete si trovano molti esem...

Updated for printing at shapeways.com
mostly for my self but if you want to help  support development that's cool too :D

You can also find this at thingiverse.

Eventually i will draw up the main plate and make a version that will be a bit more maker machine ready.

My Arduino kitchen Garden made with a converted wine chiller.  Works pretty great.  Instructions posted, code posted soon.  Open source for all to enjoy hopefully.  Give it a skull if you like as it is submitted for the 2015 prize too.  Cheers!

Having long enjoyed growing my own food I searched for a commercial unit to allow me to grow vegetables , herbs and micro-greens/sprouts year round. I found commercial products to significantly lack the control and enclosed-nature I desired to grow what I want, when I want without buying their proprietary seeds/pods/modules. I converted a peltier driven wine cooler into a grow chamber and powered it with a simple Arduino for control. The ...

Basil is a pretty hearty plant. Other than in tomato sauce I can't think of much use for it myself. Mostly I'm growing basil for insect control. I should probably plant sooner than I do. I can start growing some things in the beginning of March here. I ripped out my bed of peas yesterday, and I have to put some squash in there now. Most stuff I planted in May though. Things will grow to November. I'm going out into the garden now. My cucumbers are starting to come in.

+Heilman Hackatronics It's not really about preference, there are tasks for which DSOs are necessary... You can't press stop on an old fashioned analog scope because it has no storage/memory... So in that way measuring that serial transmission wouldn't have really been possible.

Check out this Linear bearing adapter for 8020 1" extrusions i drew up.

I would appreciate feed back and/or someone actually printing them sadly my printer is not ready yet.

+Solidus Labs  thanks for the inspiration.... no joke, this was staring me in the face for months. i have held both 5/16 BBs and 1" extrusion in my hand many times thinking of way to do this very thing.

Also i am putting this up on shapeways.com to hopefully get a proto-type made.  I will be posting the link to where you can buy them if like me you can not print yet.

There are more beefy version as well if there is an interest in not saving much material. i trimmed it down to make it cheaper on shapeways.

8020 1" Based Linear Bearing Big Kudos to Solidus Labs as i stumbled onto a delta design with this concept in it. He was working with different extrusion than this though. I plan to also do on based around the misumi 1515 as my soon to be finished delta has this extrusions. This is still on going and will need a bridge between the two extrusions used for the bearing. The bridge can then be mounted to your gantry, delta arms ect.... ...

The first one (yellow) had the rear valve's diaphragm off base.  Additionally, the O-ring on the bi-directional valve had lost grease sealing.  The second one (blue) had the front valve pulled off and its O-ring jammed between its stopper and the shaft.  Some Vaseline and 30 minutes after, both pumps are back in working order.  Net profit?  $8 in replacement value.  In manufacturing value, perhaps $2, minus materials cost.

Really?  I most probably did not make minimum wage.

A college roommate of mine was a graduate student in Columbia University many years ago when he saw some dull drill bits in the lab and took care to sharpen them. He was very proud of tooling skills that he picked up after high school when Chairman Mao shut down China's universities and ordered the youth to "be reeducated by workers and peasants."  When he was busy showing off his accomplishment in the lab, his professor walked up and offered this: "I didn't pay you to sharpen drills."

Well, I don't have the pride of hand skills - of which I have none.  And even though the owner of these pumps, www.ClimateChangeEducation.org, couldn't claim that they didn't pay me to repair pumps - nor could they claim that they paid me to, for this is all on volunteer time, I am sure that Jim would rather my time be spent on actually improving the educational infrared hacks that his collaboration with my +Hackerlings have produced.  The pumps were used in public exhibitions where we showcased our collaboration.  The yellow pump had been lousy from the beginning.  In the most recent show, the blue one also faltered.

To Jim, replacing these pumps is too low a cost.  But to me, this is one opportunity to learn something about mechanics and product design.  If I hadn't opened these pumps, I wouldn't have known that, simple as they are, there are different mechanisms to construct - and techniques to produce them.  This reminds me of Mark Frauenfelder's first handmade wooden spoon described in his Made by Hand: Searching for Meaning in a Throwaway World.  All these simple builds add up to one's skills.  That is where I find value in my time.

And hoarding skills is not purely a selfish endeavour.  If, for example, the next time a pump - even a replacement unit, failed during a live show, I can fix it on the spot in two minutes.  How much would that be worth?

I've trashed seals using Vaseline on them. Initially it works great, but after a while Vaseline attacks the seal material. It does take quite some time. There are a number of products on the market engineered to work as seal lubricant. Some interestingly enough are even petroleum based. But being as I've already had trouble with petroleum jelly myself I tend to be biased towards the silicone synthetics myself now.

Make your own Electronic Water Tag!
https://blog.adafruit.com/2015/06/22/make-your-own-electronic-water-tag/

Everyone loves water gun fights in the summer. But you can always make something better by adding electronics to it. So I designed a set of water sensors and buzzers that will beep when they are hit with the spray of a water gun. This lets you play a game similar to laser tag but with water.

Something a little different; I make circuit inspired print dresses.

My dream is to integrate them with wearable electronics one day. Any ideas of where to start?
