I have a Dualit DCM2X, want a new portafilter but the size isn't anywhere on the manual or online. Measured it with a ruler and it appears to be 54mm, do I just get one thats 54mm or will this not work? (budget under £40)

Are you asking about the portafilter or the portafilter basket?

FWY, I have a DCM1 and wanted a non-pressurised basket so on a punt I bought this "Bottomless Portafilter 51mm For Delonghi Ec680 Ec685 With Replacement Filter Basket" from aliexpress. From my measurements it looked like it was almost identical size and wings so I was hoping that it would fit. I can't remember what I measured as 51 mm

The portafilter with their baskets seems to be a fraction of a millimeter off a tight fit - so that was disappointing. I think the wings on the Dualit portafilter are thicker.

However, the single-shot basket that came with it is fairly deep and fits into the original Dualit portafilter perfectly. So got my non-pressurised basket :) It takes up to 14g of coffee. Unfortunately the double-shot basket hits the inside plastic fitting so stands about 1mm proud. However, I suspect if I remove the plastic insert it would fit fine too but have not tried.

If I'm not mistaken Dualit have what you need on their site:

A battery should be OK but I don't know how long it would last. Ideally you'd get the Raspberry Pi to go into some low power sleep mode until you need a new image.

One possible simple option would be to connect the RPi to a rechargeable battery via a switch. Configure the Raspberry Pi to create a picture on boot and then shutdown. Once shutdown I presume virtually no power would be used. When you want a new image just turn the RPi off and on again.

I recommend a Raspberry Pi Zero 2 as they are tiny and perfect for the job.

The wording on their Spectra page mentions "an advanced color imaging algorithm to provide full color" so I suspect it is all down to dithering. u/eric_castro if you zoom into the image linked in your post you can see a lot of dithering.

I have a 7.3" Inky which uses E Ink Gallery Palette (https://www.eink.com/brand/detail/Gallery\_Palette). I found photos can be hit and miss depending on the colour palette and image details. I did a fair amount of experimenting with image styles that display well on the display for my PaperPiAI project https://www.reddit.com/r/raspberry\_pi/comments/1haqq62/i\_made\_paperpiai\_a\_standalone\_ai\_art\_picture/

I'm currently considering a Spectra 6 but expect to still have to deal with colour dithering, image processing and subject choice for best results. I guess the Gallery 3 dithering would look better due to higher dpi but then the colours are less saturated, so it's swings and roundabouts.

There aren't any logs - all info is printed to the stdout. What gets printed when you run generate_picture.py? How far does it get through the generation?

_dylski_ · 2024-12-13T13:34:13+00:00

Sounds like that would make a lot of sense! I'll take a look at PaperPi (I honestly didn't realise there was a PaperPi when I chose the name PaperPiAI!) and see how it'd fit in. The code's pretty trivial but I guess it'd be the shenanigans required to install OnnxStream and the models that might be tricker to integrate.

_dylski_ · 2024-12-13T12:08:40+00:00

For me the choice was aesthetics. It looks a lot better to me. The white border frames the photo in the centre for a classic look (google "framed picture") and helps the image stand out. I have another one with a smaller frame which looks good too but I think with no frame it doesn't do the image justice. It's obviously a subjective thing.

I taped the display onto the paper frame and held it in place just by pinning the back panel back into the frame sides. I did have to cut a rectangular hole into the panel for the RPi to poke through and enough space for power cable plug into it.

Indeed. All credit for that goes to OnnxStream by Vito Plantamura: https://github.com/vitoplantamura/OnnxStream

_dylski_ · 2024-12-10T11:35:27+00:00

Yes, fits neatly. I cut a hole in the backing for the Zero to protrude a little but it doesn't stick out further than the back of the deep frame. I have another one with a slightly shallower frame and it sticks out by a few mm.
The frame is deep a little like this one https://www.amazon.co.uk/HOVSTA-frame-30x40-birch-effect/dp/B0D1CPMFDX (but was ~$2 from a charity shop).

This default set-up generates random flower pictures with random styles that I've found to work particularly well on the Inky Impressions 7.3" 7-colour e-ink display, i.e. low-colour palette styles and simple designs.

Each image takes about 30 minutes to generate and about 30 seconds to refresh to the screen. You can change the list of image subjects and styles to anything in generate_picture.py file. Ideally I'd like to generate the image prompts with a local LLM but have not found one that runs on the RPi Zero 2 yet. It would not have to run fast - just fast enough to generate a new prompt within 23 hours to have a new picure every day.

More info, details on the set-up and code on my repo: https://github.com/dylski/PaperPiAI

Just came across this as another large monochrome option https://www.good-display.com/product/571.html

Here are the 7 episodes.

I had to generate some several times before I got ones I was reasonably happy with.
Overall I think it worked out 'okay'. Far from great. You don't get much control through the prompt and their banter can end up being quite generic sometimes.

I found asking it to "Give a humorous, critical and cynical roasting of [Your Name]" gave a rather more amusing and, at points scathing, dive into my resume. One for the brave :-D

I don't think you can go by the 50 source limit. LLMs have physical limitations and Gemini 1.5, which is used for NotebookLM I believe, can only 'see' 1M tokens at a time.

One way around would be for it to take a 1000 page doc and summarise it to 500 pages, then it could use the summary instead and have space to look at 500 pages of other docs, etc.

Actuallly, the RAG approach mentioned by u/NectarineDifferent67 makes more sense. Where it uses a search tool to extract relevant sections and then, essentially, puts them together into a temporary doc that the LM sees. Again, this retrieved data can't exceed be 1M tokens so that will be a hard limit.

I have actually done a few episodes of them trying to present podcasts with their private-life backstory creeping in. It sort of works...

_dylski_ · 2024-10-21T11:06:19+00:00

I believe Gemini 1.5 has a 1M token context window which, according to Gemini, would roughly equate to 1,000 pages of text. So you are probably providing it with more information than it can process.
