In this video, I perform the Mylar repair which every Atari 1200XL keyboard eventually needs. Sometimes the carbon contacts on the Mylar survive virtually intact, and luckily that was the case here. Unfortunately that also means that this keyboard was no use as a demonstration of carbon pad repair, but maybe the next one we fix will be. :) ▶Bob Wooley's original 1200XL Mylar repair guide: http://www.retrobits.net/atari/keyboard.shtml Apologies for the muffled audio when the hot-air gun is running, by the way. ▶Donations: https://www.paypal.me/flashjazzcat ▶Website: http://www.atari8.co.uk ▶Facebook: http://www.facebook.com/atari8/ Equipment and software used for video production: ● Open Broadcaster Studio: https://obsproject.com/ ● Logitech B910 webcam: http://amzn.eu/42EH5Qf ● Logitech C910 webcam: http://amzn.eu/gxMSNg0 ● Bolun WR-601 Wireless Microphone: http://www.ebay.co.uk/itm/NEW-Bolun-WR-601-Microphone-Transmitter-Receiver-Set-with-Microphone-/261988139597?hash=item3cffb5c24d:g:Q48AAOSwpP9Y8U~Y ● EZCap USB AV/s-video capture dongle: http://amzn.eu/gW2mF5O #atari #retrocomputing ... https://www.youtube.com/watch?v=8qBWuxZI630

First attempt at clickable command buttons in the new GUI. The 3D effect is pretty rough at the moment and I'm testing out a few different designs, but the basic machanics work. ;) ... https://www.youtube.com/watch?v=zWy9CgAbvEo

This is a 'private' video the client suggested I publish, and I'm doing so now in order to provide the channel with some content while I'm in the middle of moving house. Hence: no early-patreon release, patron credits, etc. The machine actually came back yet a second time after this video was made, and since I still have the machine here (which is now 'definitively' fixed), I'll make a follow-up video once the new recording facility is set up. Apologies to all for the lengthy hiatus (made worse by the death of Deborah's mother on 30th August), but we hope to be fully installed in our new home before the end of September. ▶Donations: https://www.paypal.me/flashjazzcat ▶Tip or donate: https://ko-fi.com/flashjazzcat ▶Patreon: https://www.patreon.com/flashjazzcat ▶Website: http://www.atari8.co.uk ▶Odysee channel: https://odysee.com/@flashjazzcat ▶Facebook: http://www.facebook.com/atari8/ Soldering and test equipment: ● Hakko FX-951 T12 soldering station: https://uk.farnell.com/hakko/fx951-64/soldering-station-75w-230vac/dp/3367978 ● Best BST-863 hot air rework station: https://www.banggood.com/BEST-BST-863-1200W-220V-or-110V-Intelligent-LCD-Touch-Screen-Heat-Air-SMD-Rework-Station-p-1431173.html ● Anesty (Duratool) ZD-915 thru-hole desoldering station: https://cpc.farnell.com/duratool/d00672/desoldering-station-uk-eu-plug/dp/SD01384 ● Hanmatek DOS1102 dual-channel oscilloscope: https://www.amazon.co.uk/DOS1102-oscilloscope-Professional-Oscilloscope-Bandwidth/dp/B0833X3RFK ● Amtech NC-559 Tacky Flux: https://store.rossmanngroup.com/index.php/amtech-nc-559-v2-30-cc-16160.html ● Goot Wick Desoldering Braid: https://store.rossmanngroup.com/index.php/ab20-gootwick-1-5.html ● Cynel Sn60Pb38Cu2 Tin/Lead Solder Wire: https://www.tme.eu/gb/details/lc60m2-0.7_1.0/solders-wires/cynel/ ● SysCheck v.2.2 by tf_hh: http://www.abbuc.de/component/jshopping/hardware/syc Equipment and software used for video production: ● Open Broadcaster Studio: https://obsproject.com/ ● 2x Logitech Brio webcams: https://www.amazon.co.uk/Logitech-Gaming-Webcam-Streaming-Compatible/dp/B0748NCPN5 ● USB AV/s-video capture dongle: https://www.amazon.co.uk/Ex-Pro-Grabber-Editor-capture-Windows/dp/B001HB9C1O ● 135W Photography Studio Softbox Light: https://www.ebay.co.uk/itm/135W-Photography-Studio-Softbox-Continuous-Lighting-Soft-Box-Light-Stand-Kit-Set-/142645098730?hash=item21364f78ea ● Final Cut Pro ● Apple Motion ● 15" mid-2015 Apple Retina MacBook Pro #atari #retrocomputing ... https://www.youtube.com/watch?v=5wRnngBTwSs
