one of the first mods i did on my casio f-91w was replace the led. i’ve done it to two other casios since. totally worth the effort. by replacing the strap and led you’ve solved two of the f-91w’s biggest weaknesses. great video.
"...Anyone who has no alcohol dependence or parkinson's should be able to do it this mod...." Dude. Now I need to find a new reason to not do this mod.
Whoa bro...when I did that mod with the led I used superglue to hold it in place while I put solder on. Also you can run 2 leds one on each side makes a huge difference.
NICE!!!!!!!!!! You should get a PCB holder, because this LED mod is very cool and a PCB holder would really help you, by keeping the pcb stable in its place, while you work on it with your soldering iron. And practice more with the soldering iron on old, non-working circuit boards.
@@Techsas It's not the first F91W you modded and I think it is not the last one you will modify, so I think a PCB holder will come handy in your future videos. The LED that F91W comes with is pathetic! It barely illuminates a third of the screen and Casio uses the same pathetic LEDs on other models. This is why I was so excited about this video. Finding a replacement LED that would illuminate decently the whole screen, and modding other casio models, IMHO, would be a good content for your channel :)
Great job, congrats!!!! I've read all 73 coments and I don't solve my doubt... The LED adopted by CASIO for the G-SHOCK GA-100, are also the "0805 SMD" ??? I want to change that amber LED that is ugly as hell, for a brighter color. Success with your content is very good, congratulations again!
@@Techsas If your dead set on usb powered look at the TS80. If you just need it portable, then the TS100. If you want a station look at a KSGER T12. Your soldering made me cry too, but it's your iron.
@@Techsas Woah! Thank you. I just checked AE for that and its cheap, like 100pcs for $2. I am gonna order like 10 of each color when things become a little normal.
what was it that you did at 2:35 to make the screen correct itself? How did you do it? like where did you press? And why is it only done sometimes, but not always?
If you pause it at 2:34 you can see that he inserted tweezers in that small hole and shorted it to ground (shield) with other side of tweezers. If i remember correctly there is writting on it that says "reset"
@@cekpi7 Thanks for the reply and explanation! I wasn't 100% sure if it needed to be shorted to the outer metal shield or not! I had an A158-WEA that probably would have benefitted from this (uses same module as f91w I believe). I disassembled and reassembled the module, but it didn't initially work properly. Basically its LED lit up, it showed the alarm symbol, but nothing else on the screen. It did start working by itself after a few hours, but I reckon I should have just 'reset' like you've explained. It would have saved so much trouble.
Hey, great work again! The strap feats the watch really well! I was wondering whether it would be possible to put to LEDs on each side of the watch and connect them together with just a thin wire or something?
what is the wattage of that soldering iron? 5 watts? or the powerbank is the problem? get a decent soldering iron that uses usb-pd so it can draw more power from powerbank
Techsas that was my main concern.. but I still have hope. If an RFID tag or a layer or coloured plastic fit maybe some slim plastic film with a light would too. If I ever find the original post I saw about this and get the supplies I think I may try it. Probably not on the base model F-91w tho Édit: Layer* not later
@@Techsas Just found this th-cam.com/video/KG4K8vcScEo/w-d-xo.html I can't remember if this is the same one I saw before or an other one tho.. When it comes to the F91, maybe coating the white backing or swaping it with some lume coated plastic this could solve the space issue
Ah, the joys of welding; she is my sour-smelling nemesis. Glad to see you tackled it successfully. =) How will this affect battery life, in your opinion?
@@Techsas Hi guys! Love your content my friend, really. Fellow casio lover here. I've had x2 F91 in my life. Both I've changed the stock light to a 0805 SMD LED. First having the original Black and Blue stripe same in the video, gave it to a patient of mine that was discharged. And second the one I'm using now ever since Sept of 2019. The military green case. Also with modded light. Both of them still running strong on the original battery, even though I use the light almost all the time 😂
Use flux my dude...the surfaces aren't clean, especially the new led contacts in this video, that's why your solder wasn't sticking. Also, a clean and flat tip would greatly help

I am still amazed how good small LEDs can be
Nice. The Nato looks way better just put straight on the watch imo, without the adapters.
Well, you certainly managed to make this look like a struggle!
It is a struggle haha
I prefer the original single green light. I think it’s adequate & I like the fact that this is the exact same version as the original.
"...Anyone who has no alcohol dependence or parkinson's should be able to do it this mod...."
Dude. Now I need to find a new reason to not do this mod.
Haha just do it responsibly

kenychowsf where do you put the second led?
That's 200 IQ right here, I didn’t even think about super glue...
@@zackmerritt2408 on the other side
This video make me wanaa buy this watch, again
Just to mess with it
Haha
Good video, a before and after would've been great
Got just into CASIO modding. Awesome Vids. Please go ahead. Add more f 91 w vids.
NICE!!!!!!!!!!

Why didn't you just put the NATO on without making adaptors?
ease of disassembly
my master 🙏🏻😅 amazing , i'll wait for the next one
Donde has conseguido los adaptadores de la correa
3D printed. Link in description
I don't have 3d printer, any links to buy the 18mm adapters? Thanks 🙏 Good video!
Do you happen to sell the nato adapters? I need one for my Casio world time. Thanks!

I've been looking for a reason to get Into soldering. now I have 2 reasons. This is a must do for this watch or the clone movements
Just invest in a good soldering iron... The crap I'm using is USB powered and it makes me depressed.
@@Techsas If your dead set on usb powered look at the TS80. If you just need it portable, then the TS100. If you want a station look at a KSGER T12.
Your soldering made me cry too, but it's your iron.
I have yet to find any F-91W lug adapters as nice as the ones from Jays&Kays.
Nice as always! Adapters seems to be 3D printed. What plastic do use in case of reliability?
This is just ABS. I'm don’t really know much about 3d printing, but I would use a softer plastic next time.
@@Techsas I see. Keep skin irritation in mind, be careful.
How comfortable is the nato strap if its wet or you wear it for a few days? Compared to the original
I prefer original. It's little uncomfortable to have something wet around your wrist and it starts to smell after awhile.
I was hoping this would be a miracle cure, but it just looks like the same area is lit up, just brighter.
Agreed
How and where to find a more compatible and brighter led for this watch?
Ebay. Led is called 0805

The hole says AC it has to be shorted with + which is top of the battery and thats basically any metal part of the module.
@@Techsas Thanks for your explanation!
Love your videos btw, they've inspired me to mod and restore my own Casios
How do you replace the button? I have a problem with my LED button, it doesnt work
Hi. Are you going to sell the strap adapter in your Etsy shop? I prefer the adapter method because it makes switching the strap easier. Thanks.
Hi,
That is not a plan. There is a link in the description for 3D file. You can find someone on FB marketplace to print a bunch of these for $10.
Nice modification! Instead of changing the led (is a pain in the ass) you could invert the lcd screen making the watch more tactical. Nice video!
Thanks. I'll try next time
Hi i love your channel ❤️, big love from Indonesia
Hey, great work again! The strap feats the watch really well! I was wondering whether it would be possible to put to LEDs on each side of the watch and connect them together with just a thin wire or something?
Thanks. That is possible, someone already did it.
what is the wattage of that soldering iron?
5 watts?
or the powerbank is the problem?
get a decent soldering iron that uses usb-pd so it can draw more power from powerbank
Awsome work! What is That stuff make easy link to NATO band !
It's a Nato strap adapter. There's a link in the description for 3d print
Techsas So kind~ Thank you Techsas👍🏻
Where can I buy this adapter? I`m in Brazil actually.
Please please tell me where I can get those conversion pieces for f91w
I can’t find them anywhere I can only find for DW5600
It's 3D printed. 3D model is in description.
Yeah just use your household 3d printer. You know.. that thing that everyone has.
Would this work with the casio w86?
I’ve seen this one done once on a G-Shock : full lume background behind the screen. Do you think you could look into it ?
There's very little space in there to do something like that
Techsas that was my main concern.. but I still have hope. If an RFID tag or a layer or coloured plastic fit maybe some slim plastic film with a light would too. If I ever find the original post I saw about this and get the supplies I think I may try it. Probably not on the base model F-91w tho

@@Techsas Just found this th-cam.com/video/KG4K8vcScEo/w-d-xo.html
I can't remember if this is the same one I saw before or an other one tho..
When it comes to the F91, maybe coating the white backing or swaping it with some lume coated plastic this could solve the space issue
I think it would have been better if you put a yellow or orange on it, like the JAPANU retro models
Yes, next time!
Lol you should fix the strap after it breaks😊❤️
hello sir, i don't have 3d printer. any ideas where i could buy those strap adapter?
No idea. Ask someone to print it for you.
@@Techsas duly noted. thank you very much.
Music best everytime!!!!!!!
Thanks!
is this 18mm strap?
What size adapter?
maybe you can do double leds in the future
I will try
What changed with the led?
any link for the adapter ?
In the description
Very nice
Thanks!
Thank u my brother
No worries
Great video, but ummm the green strap looks wrong...
I don’t think adapters are needed on an f91w for a nato...
I don't think anything is needed for F91
Techsas that is the best response possible you could’ve given. I subscribed
Whats wrong with your volume in all your videos ?
What's wrong with it? Too silent?
@@Techsas yep master! Pls correct this if you can. Peace!
Ah, the joys of welding; she is my sour-smelling nemesis. Glad to see you tackled it successfully. =)
How will this affect battery life, in your opinion?
Have no idea. I'm sure that the old led is much older so maybe the battery life is improved now?

How many mm nato strap?
18
great
Casino saat güzel videoları gelsin yarın inşallah abi
Just buy the F105 Iluminator instead
I have 5
Eyeballing my 3D printer after just paying $20 to Jays and Kays...
Or just buy the model F-105 Illuminator
Very rugged/military watch...
You're so bad at soldering. I'm worse 😭
I'm planning to learn, some soldering videos are so satisfying haha
Step one: Get another iron. A TS100 or KSGER T12. Keep that one in case you need to melt plastic (not really safe).
F91W doesn't look good on nato strap, unfortunately. Looks quite odd and disproportionate. F84W is another story.
