Had a properly successful session on the EU feld hell net this week with the #Meccano #hellschreiber
My new tone generator circuit using the VCO of a 74HC7046 makes a much better signal than my original, largely unfiltered, 555 oscillator lashup, and the group commented how my characters look much better now that I've stretched my pulses a little.

Alas new problems are appearing as the machine starts to wear out from too much use! 😆
The elastic is getting very soft so keys are not always returning properly, and the ever present character drum corrosion issue has been joined by "kapton tape starting to fall off itis".
I was expecting that from the very beginning though, and surprised it held up as well as it has. A few repair patches made with nail varnish last week seem to be working OK, so I will probably go through and use that everywhere bits are starting to peel/falling off.

一位 Meccano 愛好者在多佛的一次受邀演講中,於達文西自動車的一個大型複製品展覽中得到啟發。透過研究網絡資料,他了解到許多學者對達文西的素描進行了許多研究和解讀。他的模型和實際測試成功地模擬出達文西車輛的運作原理。
+ 這位愛好者真的花了很多心思和時間去研究和模擬達文西的自動車。這項工作非常引人入勝,且對歷史和科學有重要意義。
+ 這篇文章真正展現了人們因對歷史和科學感興趣,而投入大量時間和精力來研究和模擬歷史上著名發明家的作品。

We spotted the XYZ Cargo bike at the National Cargo Bike Summit and had to follow up with MJ Somerville. Who doesn't want to build their own bespoke cargo bike (with a bit of help)? We love this idea and the doors it opens for people who otherwise might find the right fit difficult:
