Vintage Computer Fest SoCal
by Levi C. Maaia, K6LCM 14 Nov '23

14 Nov '23

Hi guys, I am passing along information about VCF SoCal, the first Vintage Computer Festival in Southern California. I attended VCF Southwest in Dallas and VCF West in the Bay Area last year and loved these events. It’s like a ham fest but for vintage computers. And there is a lot of crossover with vintage computers and vintage radios. Folks are using Commodore 64s and Apple Its to track the ISS and connect to Packet Radio systems and RTTY. It is very cool. People also bring things that could be museum pieces like vintage Soviet workstations and all-analog, vacuum tube computers as well as a ton of other tech from the 60s-90s. **See the photos attached.** I’m on the org committee and a sponsor for VCF SoCal. I’ll be exhibiting some stuff myself at the show down in OC this February. Check it out and consider coming down for it! https://www.vcfsocal.com/ LCM Levi C.

This is the battery I had at the SBARC picnic - on sale at Amazon
by Dave Schmidt 03 Oct '23

03 Oct '23

This is the 100A LiFePO4 from Redodo. I've had this in my Amazon shopping cart and I see that today's price is very good. $269 - $40 = $229 with free shipping. https://www.amazon.com/dp/B094NN5KWY I ended up buying another pair at an even better price. $455 - 10% = $410 or $205 each (but you have to buy a pair) https://www.amazon.com/gp/product/B0B2QP1T5T Note that these physically are the same size as a lead acid AGM 100AH battery so it fits into battery trays that used to hold AGMs. 100AH 12V LiFePO4's are also being sold as 'minis' where the case is smaller, but many of those are using pouch vs prismatic cells. I don't have an opinion on one being better than the other (pouch vs prismatic), just letting you all know. Dave AI6VX
