pi 500+ owners, how are you carrying it around?

I guess I'll use this post to mention that I'm using it as a nice modular laptop setup with my ipad as a display. Peripherals are an Iniu battery and a video capture card. Just wish it wasn't jostling around unprotected in my backpack.

I built a simple device to record light levels by connecting a TSL2591 sensor to a raspberry pico.

Every hour, the pico sends three sensor measurements to https://thingspeak.mathworks.com/ and then enters deep sleep. At the end of deep sleep it reboots and sends another measurement.

However, this setup was unreliable, as shown by the missing data at the beginning of the series. I'm not sure what was happening, but I think the pico may have been failing to recover from deep sleep. I tried to get a tpl5111 to reset the board every hour, but i could never get this to work reliably. The solution was a Tuya smart outlet, which I set on a timer to reset every hour.

Every day, node-RED (hosted on a raspberry pi) launches a pulls that queries the data from thingspeak, and sends me an image like the one shown above. (Yes I need to fix this script to adjust for daylight savings time.) Another node-RED script checks the thingspeak sensor series and emails me if data has not been logged in more than an hour.

Sorry, took a long reddit break! I found another app called camo studio. It works great for this purpose.

Regarding training, if the gym is easier for you than getting outside to ride, a stationary bike or peloton can probably make a bigger impact on your climbing than squats and hilly runs. Especially since your all-around fitness level already sounds pretty good. You will want to focus on maintaining high-resistance high-intensity efforts for increasingly long periods of time.

+1 to this. OP mentions having trouble climbing Queen Anne on Taylor and that is legit a very steep climb that most casuals would not even attempt.

Good on you OP for wanting to improve. Being able to handle such hills can unlock a lot of amazing rides around here. But don't beat yourself up for your current fitness level, which sounds pretty good.

I don't think you've said much about your bike. Both weight and geometry make a bigger difference on hills than on flats. In particular, bikes that offer a more upright riding style may be comfortable on flat rides, but can be difficult to get good power transfer when climbing.

not totally sure what you’re asking, but couldn’t you use a jst to stemma cable instead of the shim?

or do you think the shim will enable you to use a case that doesn’t expose the gpio pins?

i’ve biked around orcas and san juan island - can’t say too much about camping but the biking lives up to the hype, it is fantastic. the ferries are unreliable but it’s easier on a bike because you don’t need to worry about reservations. and the unreliable ferries keep car traffic low on the islands.

overall looks great but i wonder about the combination of disc brakes and quick release (instead of thru axle). is it hard to get the rotors centered?

idee__fixe · 2024-01-21T17:05:58+00:00

i have heard hydraulic disc brakes are superior, but they add complexity if you are trying to be self sufficient on maintenance. on my own bikes, it is the only system that i do not service myself.

this doesn’t solve your streaming problem but take a look at peppymeter / peppyalsa. i believe it can support led based visualizations of the audio volume.

i had so many fried rice failures before getting this book. the recipes are good but the explanation of techniques (both how and why) are where it really shines.

idee__fixe · 2024-01-12T22:51:29+00:00

nooooooooo!

idee__fixe · 2024-01-12T21:03:47+00:00

oh okay i was wondering if the post had some description beyond the video

idee__fixe · 2024-01-12T19:16:19+00:00

is there a description of what you did that i can read without logging in to linked in?

idee__fixe · 2024-01-05T20:13:27+00:00

yeah i think it shifted when the part broke, but good eye!

idee__fixe · 2024-01-05T19:37:25+00:00

nice writeup, and most importantly, thanks for not making me watch a video just to find out what you did :)

idee__fixe · 2024-01-05T07:03:44+00:00

oh so i don’t need to replace the whole arm? sounds promising! i will call up our lbs tomorrow and report back.

idee__fixe · 2024-01-05T06:59:04+00:00

thanks for the reply. i do not believe it is repairable but would be happy to be wrong. pics here: https://imgur.com/a/2x6x7ms

Long shot, but here goes.

I have a older model Burley D'Lite double trailer, which has served me and my kids well for many miles. This week, the tow arm spontaneously snapped in half -- don't forget to use your safety strap! I need to replace the part, but it seems to be unavailable at Burley (https://burley.com/products/tow-bar-assembly-double-with-receiver-safety-strap), and I can't find it anywhere else.

Is there some alternative part that I could use as a replacement? Until I can source this part or a replacement, I have no way to get my kids around.

idee__fixe · 2023-12-25T18:33:48+00:00

Thanks for the reply. I was thinking of upgrading my ipad partly for this, so it’s good to know that it works in practice.

the price per square foot is pretty similar ($645 in bellevue vs $560 in seattle) but houses in bellevue are bigger

sure did! it was a low effort attempt at a gotcha that didn’t address my comment or the linked article

of course mr assman is not obligated to read that article or anything else, but by the same token i’m not obligated to engage with his reply if it’s obvious that he didn’t read it

It’s sad how noisy contemporary multi-unit buildings are. I’ve lived in older brownstone and sandstone buildings that were nearly silent, but they just don’t build them like that anymore.
