Dull Men's Club
An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

Yeah it's on the website linked from the blog post.
Indoor kit is $230USD or $138 for the DIY.
Outdoor kit is $225 or $125.
No, I don't know why the outdoor kit is cheaper than the indoor one 🤷
The components look like they'd cost closer to $60 USD, but you'd need to print a PCB and create an enclosure.
My biggest question, for both the DIY and make it from scratch versions, is since they don't get tested like the prebuilt, how do you know it's measuring accurately?
The sensors are preassembled, so I assume the result would be the same. If there's variation in the enclosure that changes the airflow, then yeah, that could cause differences.
Presumably some percent fail the test but most pass. How do you know if you've got a dud?
I have owned enough electronics to know the percentage of duds is higher than you'd hope 😅
