Building an Open Reel to Reel Machine: Harder than it Looks

This took me WAY to long to make, but finally I bring you this.

Nice video! One thing that I noticed is that you are trying to record on the tape using only the audio signal but to record properly you need the bias. I dont know for sure how it works but you need to modulate a high frequency signal (something like 50khz to 150khz) with the sound signal and then feed it to the record head. If you plan to continue using normal Type I cassette tapes you can search on the internet how the bias signal is generated on a tape deck for a Type I cassette and then you can try to replicate it on your project. Greetings from Brazil!

Holy crap, that's some nice hack! Making your own experimental tape is taking stuff to the next level. If you want to record the tape, you'll need an erasing head before the record/playback one, and some high frequency bias current on the recording head. Otherwise you won't go far when it comes to noise and distortion, even on factory-made tapes.

The soldering montage! 😹

[@CamdenBowen]

Glad you liked it!

[@wrx-3]

Yeah that was good

[@dr.zarkhov9753]

😂😂😂

[@svofski]

This is really cool and interesting. Don't give up. The interference can be helped by shielding and moving the motor away. The heads can be attached to the amplifiers using shielded cables.

[@natethefighter]

I have thought about and wanted to try this EXACT thing. Cool to see and to read all the comments and suggestions from folks. Thank you for sharing this with us!

[@manclt704]

@CamdenBowen I don't understand what you were trying to do. The magnetic tape should be extremely fine and uniformly coated with a ferrous material. To record and play back audio, the tape must move in one direction at a consistent and uniform speed (never back and forth like a saw motion). During recording, an "erase head" should be used before the recording head to align the ferrous coating and erase any previous recordings. Additionally, a bias signal of 50 kHz or higher should be added to the actual audio signal to improve recording quality

I'm so glad I found this! I knew somebody must have tried it

[@thallrudedjentstorm1756]

I didn't even start watching the video, but boy oh boy... you started an very time consuming, nerve-racking and highly complex project. I made myself some pop corn... Here we goo

[@mistergreeen]

The reel to real machines go outside to outside, you spooled outside to the inside of your uptake reel so that might have an affect on your tension, but I don't know if you would have to reengineere yout gears to get your uptake to go in reverse

[@10gaugesbelow]

Thank you. Iv wanted to do this for years

Looove these montages!

Let's make some noise!

[@kaandle]

Hi, great job! A really nice project. I'd love to build my own and experiment, hack, improve... Unfortunately I can't access to your google drive folder.

[@noitaplayer1231]

Hello, ive been trying a similar device, creating a casette recorder / player, and the magnetic fields of a dc motor can interfer with the devices sound, and so keeping the motor away from the tape head or any connective areas, can decrease the noise, and the frequency should be lower, 2 9V batteries is a lot, i have got no résult yet, but i will attempt with a lower voltage, and may i ask, does your magnetic have a common ground or is it DC?

[@johnnyhellfire6]

Is there a link on how to make this? I'd love to try making one?

[@CamdenBowen]

Unfortunately not really, this is something I had to figure out on my own however here is one of the websites that helped me: qz.com/emails/quartz-obsession/1156672/

@@CamdenBowen I can dig, would you happen to be hip to sharing the stls? Not to pester you, just have an idea and I'm one of those folks that cant really verbalize it, I just gotta do it to show what I mean. Plus, I'm just now getting use to cura so cad is gonna be fun to relearn lol I've killed alot of brain cells since college lol

cool video!

[@CamdenBowen]

Thank you!

[@philpilkington]

+1 for your sheer tenacity. Do you ever try anything easy?

[@CamdenBowen]

I find easy things aren't as fun, so not often ha

[@charlesyoung8600]

Holy shit, they still make cassette tapes?

[@CamdenBowen]

Apparently, the box these came in however was roughed up making me think this was new-old stock. I never found any information regarding the date of manufacture so I can't find out

[@jimmym1453]

Yeah

[@bobsbits5357]

hi i got a emi BTR 4 slave decks from a man i know cor what alot of work i have to take all the slave wiring out i picked up 8 1/4 in 1/8 basf spools you may not know about the they used to sell 1/8 tape on them for ddubing game i had 40 pancakes from the usa before prices got silly so i have some 1/8 reel to reel decks doing anything with 1/8 reel to reel is a right pain i can tell you best to keep away

Make it as a usb media 😅

awesome video, too bad it didn't do shit lmao

Too small, doesnt work for masking tape

[@anthonyludington8320]

I just asked for access to the files. I have some ideas to make this work

[@CamdenBowen]

Should be fixed now!

[@owen28vdv66]

Uh oh stinky

[@Earth_Elemental]

Bad

[@rorypenstock1763]

I'd like to offer some constructive criticism. In my opinion, the effects at 3:08, 6:32, and 7:29 are off-putting and add nothing to the video. Your channel has some very interesting projects, and I'm excited to see what you'll do in the future, so I hope all the more that you don't inadvertently begin to make your videos annoying and hard to watch in the name of production value.

[@CamdenBowen]

I agree, I was still trying to figure out how I should edit my videos. I just posted a new project video and used little editing to keep it authentic that you may appreciate :)

[@JordaoDM]

I like it

[@remiremillard8419]

totally disagree, the effects made it pretty entertaining
