For my fellow maker/hacker/nerd/geek/ham radio folks, May's EFM reminder is out - LMK if you will also be attending

The Electronics Flea Market (http://www.electronicsfleamarket.com/) is held in parking lot 2 of the West Valley College in Saratoga from 6:00AM until noon. Please don't arrive in the area before 5:30 AM as we need to maintain quiet until 8:00 AM. Avoid lot 3 parking, as it is for the farmers market operating there on the same day.

printervention: the backstory

Hivemapper Dashcam HDC S
Model: HDC-S-0HE1-001
S/N: HDCS 807

Well, this is an “interesting” device, I grabbed it from ewaste thinking this could be a good webcam or security camera. And it is, in a way – a dashcam that they supposedly paid you in cryptocurrency to drive around while this documented the scenery and road. In short, some custom hardware for mapping roads as you drive, so you can earn their custom cryptocurrency which has devalued. These HDC-S models are recently EOL, and are not recognized in windows or OS X (I have not tried Linux or BSD). They are listed for stupid money on eBay, but I was unable to get them to work for anything.

Picked up this interesting data logger for the Atari Portfolio from IBP Elektronik: Portalog DVM/Logger Interface 🧐

Found in a box of parts. Don't know what happened... but I can Hear & Smell what it must've been like! 😆

For my second entry in #marchintosh is this #spicyPillow in a 2012 Mac Pro. IIRC I picked this up at #EFM #electronicsFleaMarket on the cheap, fully intended for a project but was packed up from the move. Unpacked the box this weekend, and noted the lid being pushed out – and upon opening noted the touchpad broken in half.

I opened it up & pulled out the spicy pillow, installing a spare battery I had on hand. Connected power, and it booted! The touchpad works, but to click/double click you have to push down to make the touchpad level while clicking/double clicking. Time to find a replacement touchpad, and when I do then also max out the RAM while installing an SSD.
