04:18 AM polprog: rue_mohr: not flyback
04:49 AM polprog: rue_mohr: https://i.ibb.co/gFDPFh2/IMG-20190522-111513.jpg

08:27 AM rue_bed: heh, everyone ignores what I say, and puts dc on the filament
08:27 AM rue_bed: thats flyback
08:28 AM rue_bed: boost
11:02 AM polprog: rue_bed: ill be making an ac filament supply now
11:02 AM polprog: i think i said that before, that i dont like putting dc on the filament
11:07 AM polprog: [00:51] polprog: nah filament supply needs to be done proper
11:07 AM polprog: === ac
11:35 AM polprog: I think i have an idea how to generate 2 VAC....
11:35 AM polprog: ill have to experiment
11:36 AM polprog: i could bias one end of the filament at 2.5 or 2 and apply a 5 or 4 v square on the other end...
11:36 AM polprog: i can generate that square with the hct14
11:37 AM polprog: what do you think?
11:38 AM polprog: or just make a h bridge with BJTs
11:38 AM polprog: i have to check what bridge ICs i have an will any of them work at as low as 2V
11:40 AM gsi__ is now known as gsi_
02:17 PM polprog: :O i need a new lab notebook, this one is nearly empty
03:51 PM polprog: https://i.ibb.co/khk1xBs/IMG-20190522-224623.jpg
03:51 PM polprog: grid and segment driver ok
03:51 PM polprog: ill do the filament supply tomorrow
03:52 PM polprog: i had to turn the anode voltage to 20 odd volts
04:20 PM polprog: https://www.youtube.com/watch?v=6cUB1lFkIsE
07:09 PM rue_shop1: I wonder why its dim
07:10 PM rue_shop1: is that on the hot or cold end of the filament?
11:40 PM day__ is now known as day
