omf Posted April 25, 2017 Share Posted April 25, 2017 so i have been thinking about this and was looking as one does, and i came across this on ebay http://www.ebay.co.uk/itm/AC-DC-5V-1A-1000mA-Power-Supply-Buck-Converter-Step-Down-Module-Small-Size-/191879043673?hash=item2cace1da59:g:tpUAAOSweW5VeVqx I did try and do something similar with a hefty heatsink and a load of voltage regulators and capacitors once but I got some image distortion during my tests so abandoned that idea, what I want to know if anyone can help is would this deliver power clean enough to run a Colecovision without any image distortion it maybe worth getting one just to try at that price but wanted to see what others thought first Quote Link to comment Share on other sites More sharing options...

chart45 Posted May 4, 2017 Share Posted May 4, 2017 i posted this in the hardware forum but it was moved here to be more on topic to see if anyone could help. so what do you guys think?? i use cfm40t it can be fit in the coleco and give you all the power you need +12 +5 -5 so you still can connect the roller controller behind the coleco Quote Link to comment Share on other sites More sharing options...
Bmack36 Posted May 4, 2017 Share Posted May 4, 2017 It isn't an internal mod, but something I have been working on. It runs on a stock cv with no mods and just uses an off the shelf 12V power supply. Quote Link to comment Share on other sites More sharing options...
omf Posted May 7, 2017 Author Share Posted May 7, 2017 i use cfm40t it can be fit in the coleco and give you all the power you need +12 +5 -5 so you still can connect the roller controller behind the coleco thanks for the part number, it gives me a place to start for a working power supply i looked on ebay at http://www.ebay.co.uk/itm/Very-Handy-3-voltage-Poject-Power-Supply-Mains-input-with-12v-5v-3-3v-Output-/322479449518?hash=item4b1545e5ae:g:casAAOSwknJXyuj7 but this seems to be a variant of cfm40t, this is CFM40T-07 which doesnt have the -5 volts which isnt a major issue i suppose, it is the only one that appear after putting in cfm40t. it looks a bit big for what is needed Quote Link to comment Share on other sites More sharing options...

omf Posted May 15, 2017 Author Share Posted May 15, 2017 (edited) ok i picked up one of these power supplies i mentioned in post one during a much larger ebay parts order. it works a treat. it outputs 5v only so it only appears to work if you have a F18a installed does anyone know the power requirements of the SGM, will that work on 5V only?

SiLic0ne t0aD Posted May 20, 2017 Share Posted May 20, 2017 You can use 5v with SGM, thats how my console is set up right now and everything works fine. Quote Link to comment Share on other sites More sharing options...

H454 Posted June 6, 2017 Share Posted June 6, 2017 Here is my album of how I modded my CV. Might be something useful for you in there. Do you have a part # on the PSU? Is it putting out 12v, 5v, -5v? 120v input? Thanks Quote Link to comment Share on other sites More sharing options...
Unstablewarpfield Posted June 6, 2017 Share Posted June 6, 2017 The power supply I used is a Meanwell RS-15. I installed the F18a board so I don't require -5V anymore. If you don't put an F18 board in you could get one of the Meanwell powersupplies that delivers -5V, 5V and 12V. It takes anything from 100 to 240V input. I plan on making something like it for my Intellivision but the voltages on that one are a bit more difficult to obtain. Quote Link to comment Share on other sites More sharing options...

I plan on making something like it for my Intellivision but the voltages on that one are a bit more difficult to obtain. I figured it was a two out. I've got a mean well three out, but was hoping someone found a small enclosed three out. Will be trying out this external one in the future: https://www.jameco.com/z/GP25A13A-R1B-Mean-Well-28-5-Watt-5V-12V-5V-Triple-Output-Industrial-Table-Top-Power-Supply_2254151.html Just uses a din 5 connector. Looks like an AA member has had success with a ti computer. https://atariage.com/forums/topic/252838-ti-replacement-power-supply/ Quote Link to comment Share on other sites More sharing options...
