It's been a quiet period in the shed as we've had a new addition to the family :-)
But on the subject of quiet, my Atari Falcon's replacement fan certainly isn't. What can I do about it easily & cheaply?
Here I measure the fan's current draw from the 12V line, introduce a resistance, measure the current flow after that and make sure the resistors can take the power dissipation.
I finally decide on 4x330 Ohm quarter-Watt resistors in parallel is the best compromise for me. 2x300 was quieter still, but I was concerned I'd lowered the cooling performance to much, given I run an accelerator too.
Here's a similar approach, but using a linear regulator to drop the 12V rail to 8V: exxosforum.co.uk/forum/viewtopic.php?p=9330#p9330

![[B-Roll] Investigating DSTB1 AltRAM issues on the STFM](https://i.ytimg.com/vi/qlkzcWYLDVo/mqdefault.jpg "[B-Roll] Investigating DSTB1 AltRAM issues on the STFM
Introducing the B-Roll series.
Ive not a lot of time of late to work on any projects and to produce videos, so to keep in touch Ive started a new series of non-narrative videos that Im going to call B-Roll.
This is the sort of thing larger channels would have a second channel for. Less edited, less produced, probably no conclusion. More behind-the-scenes, stream of conciousness type output to show what Im working on and how without necessarily telling a story.
Feel free to go big on the thumbs down if this is not something you want more of, else expect more of these than main videos for the time being.

Today Im trying to work out whats wrong with my DSTB1. Im working on a new SDRAM driver in the firmware and getting nowhere. I then realise my booster seems to be unpredictably unreliable in release configuration having worked beautifully in the past.
What gives?
