As silly as it sounds, this water warmer for baby bottles: https://a.co/d/hhJzLBn

Nothing's worse than trying to mix the perfect water temperature at 3 AM while the baby is screaming, waking up the rest of the family. (We use pre-boiled water for the baby's bottles, so it's not as easy as adjusting a tap.) We bought this after we had our second baby and it's made feeding the baby slightly less stressful.


I use the hot water outlet on my espresso machine. It's temperature controlled by a PID


Or you could do what we did, which is give the baby cold milk straight from the fridge. He didn’t seem to mind, and now won’t drink it any other way!


Exactly what we did with all 3 of our kids. Made a few bottles up ahead of time. The last time we were at the pediatrician with our youngest (who is now 7) and told that to the nurse she was a bit aghast :)


True, that's the ideal scenario! We've tried room temperature milk in the past, but our baby refuses it :(


To be fair, I wouldn't drink room temperature milk... Hot or cold, but definitely not in-between :D


We have a machine that just auto boils and doses the formula water at the right temperature. You can go from zero to a bottle ready to feed in under a minute. I am sure you can get an equivalent where you are.

Highly recommended.


My wife and I have been using an electric kettle that can be set low (105°F) to heat bottles. It's not perfect, but it's good enough and nice not to have an extra appliance on the counter.

We use this OXO kettle:

I did some research and testing when buying it when our last kettle died... It's thermometer is accurate, it's 1500w and I like the interface.

Hopefully this is useful to some apartment dwellers out there


We have the same one and used for the same purpose. The only complaint is I wish the temperature setting wasn't a rotary dial. Going back and forth between lukewarm (100) and coffee brewing temp (195) requires a lot of rotations which could be a few button taps.


I'm a big proponent of co-sleeping and breastfeeding. Of course, I'm the father, so it's less of an inconvenience for me. But much easier for mom to roll to her side and feed when the baby wakes up. We still use the bottle warmer when I'm the one caring for the baby and need to warm up some milk though.


We went with the baby brezza formula pro which mixes, warms water, and dispenses into the bottle all in one click. Worth the $, every time we travel we hate ourselves for not bringing it.


My wife and I used various warmers and threw them all out for microwaving water. 8oz is 30 seconds. 6oz is 22 seconds. It's easy, fast and reliable every time.


I got excited by this idea because I would like to use it for shaving gel...


Currently running on a t3.medium AWS EC2 instance! (My max budget is currently $50/month since I get that much in AWS credits each month for building an Alexa skill a few years back.)


Very interesting, I will look into this! Thanks!


Sorry all for the long wait times! Was not expecting much interest. At the very least, I need to look into removing photos from the queue when people exit the page.


I wouldn't even let people add new images to the queue if the wait period is over, say, 10 minutes.


Not a bad idea!


How is the image processing being done? In broad strokes, what're you doing with the Python API?


Do water color artists use broad strokes?


Ho ho. As far as I know, you can make a wash with a broad brush.

Watercolour is a nice way to paint blurry things like oceans and clouds, which involves broad strokes.


Moving it to a larger AWS instance - will be down for a few minutes!


Done - upgraded to a t3.xlarge. Now it can process 4 images in parallel. Still not enough to keep up with HN demand, but it should chew through the queue a _bit_ faster.


It says I should keep that tab open for the next 17 hours. What happens if I still close it?

Congrats for the unexpected success :)


Unfortunately nothing at the moment! Currently working on removing images from the queue if the user has left the page (which I'm guessing is the case for about 99% of the current queue).


Fixed! Now abandoning the tab will remove the image from the queue.


Thought it was some fun context, but I can see why it might come off as a strange detail to include. Edited to remove the distraction.


Not C, but I did build a mobile app version that works offline: https://inspiral.nathanfriend.io/


Weird, what browser/OS are you using?


Latest Firefox on Debian 10

Edit: Nevermind, my security settings prevented the font download. Not your app's fault.


Thanks! I chose the same set of gears that shipped with the original Spirograph. Also note that you can achieve a similar effect by pressing "," or ".", which offsets the gear by one tooth, and then re-drawing the complete design.


Hey, author here! Fun to see this old project pop up on HN. Happy to answer any questions.

Last year I tried my hand at building a native mobile version for iOS and Android (using Flutter), which is a little more polished and has a few extra features (for example, irregular-shaped gears): https://inspiral.nathanfriend.io/


Absolutely wonderful. I noticed that the disc-shaped gears have teeth on the inside and outside. How do you get a gear to revolve around the outside of the disc?


Unfortunately it's not possible! It's the number one question people email me about. In retrospect I should have rendered the ring gears with no teeth on the outside.


I love this! Thank you. I’m curious if you know of something similar for producing harmonographs? Or maybe this is even a subtype of harmonography. I was really inspired by John Whitney’s book “Digital Harmony”

https://en.wikipedia.org/wiki/Harmonograph


I don't! Those look amazing, though.


Yea this is marvelous. I tried doing a spirograph thing way, way back (Atari 800 days), but could never get the math to work.
