Why not just use a smart plug?

 

Are there any professionally made volume mixers like the Deej? Surely that's such an obvious use case there must be? I mean audio equpitment sells for $1000s so some company must have made one no?

because a smart plug is not "old people" friendly to configure stuff like this.

the timer plug thing could save a lot of E-bike batteries from going potato in winter. the idle draw on those batteries (there's a BMS running, usually with some minor level of smarts) will drain them over the course of a few months, especially if in a cold garage. at work we get a big inrush of batteries in spring from owners who forgot about their battery over the winter, and found that the range on their bike now says a solid zero.

 

having that said - i would really prefer E-bike manufacturers just designed their chargers with a "storage" mode on it. i've seen one manufacturer do that and it's brilliant... you put it on storage mode, plug in the charger, and the charger will keep it at a safe cell voltage for long term storage.

if i recall the GoXLR could do that, but TCHelicon seems to have ditched that product line like a brick.

and unfortunately the majority of pro stuff is aimed at apple users.

 

there might be more, but i'm not aware of them.

 

on the topic of being aware.. i need this Deej thing yesterday, dont mind me as i go to buy some sliders

It's the name of a long-standing series on the channel

Why carry around a USBvalve when you can just have a power-only USB cable that simply has the data pins disconnected? I mean, it is definitely not stupid, cool piece of tech, but if you're at a point where you carry something like this, a simple adapter which will break the connection for the data pins sounds like a much simpler solution to me. Or am I missing something?

[merspieler]

Really love that video, would like to see more videos with showing awesome open source (hardware) projects!

There's still the possibility of an evil port which sends down more than the standard 5V and could damage your device. With the USBvalve, only that small device would blow up... better than an expensive laptop.

(There might be also the thing you're talking about with disconnected data lines but with over-voltage protection (I didn't look if that's a thing you can buy) and it would have to be smart cause USB-PD allows for higher voltages when negotiated so it has to account for that)

[visitor2015]

Does the USBvalve also protect the host against USB killers?

[Tejusr]

In the video top right info section says 

OLED screen - 1.50 USD

 

Where can I get one? Can anyone help me with the link for that or similar??

[merspieler]

Just picked the first off of ali express: https://www.aliexpress.com/item/1005005973981064.html?spm=a2g0o.productlist.main.5.3d885042xgaEg5&algo_pvid=42b4e932-288e-41b6-be5e-653c2a9be4a1&algo_exp_id=42b4e932-288e-41b6-be5e-653c2a9be4a1-2&pdp_npi=4%40dis!EUR!2.65!1.54!!!20.28!11.76!%40210385db17108861349108155eec8c!12000035209486469!sea!DE!4800113381!&curPageLogUid=Ph85rElCs1Uh&utparam-url=scene%3Asearch|query_from%3A few cents more expensive but... same ball park

Where is the bill of materials for the final deej?

[YoungBlade]

The intro is back! I hope it's not a one off. The videos just don't feel the same without Supernova.

[Brinstead]

by the by, the electronic air duster linked is OOS, but there are hundreds of listings with the exact same thing, some of them hilariously promising RPM up to 190k

Reviving a series its been a year since last EP, actually before that was like 4 years.

Gees I am old I remember those old ones glad to see LMG keeping up on this series.

Just looked it up now, they don't sell a bare 128x64 oled anymore and the only one available rn is the one with qt connector at $17 so not that cheap compared to the standard "bare" one you find on AliExpress

 

Same goes for sparkfun though it's a bit cheaper at $10

[John Blair Smith]

Where to get that USB-A expansion board for Pi Pico?

[dogwitch]

they do make wifi plug to do timer etc.

but it general for what ever reason only seems to use 2.4ghz with most i seen sold...

they are a pain to set up to.

[TheNorsePantheon]

The Deej is probably the most interesting one for me.

If I wanted to do it though, I'd want a proper looking enclosure (like your 3D printed one or better), however, I have zero experience in 3D printing and don't know of any businesses near me that would provide that service.

 

Additionally, there's some work involved (however simple) with actually setting up the Arduino and getting it to work.

 

Does anyone know of any product like this that are just made to order? I know GoXLR is a thing but the mini ones are selling for $300-400 AUD on Amazon. Would prefer something half that cost at most.

[darknessblade]

I have been looking for a product like DEEJ for years now, will 100% make my own.

 

SO thank you for finding it Jordan.

[Poppagiorgio]

what is the actual size of that part? scaled to big so just confirming it in my software.

A buddy and I are actually working on just that.
We have seen a couple of other similar ones from PCpanel and "The midi maker", but we couldn't find one with sliders that just work like deej. We also use apps like Voicemeeter to control the volume on our computer, so we made our own software to let the app work with voicemeeter.

 

The software we have made for it is also deej compatible, so if anyone wants to make a deej or have one already you can set it up for deej following instructions from here

Sorry for the self-promotion here, just wanted to share our project:)

It's the same for me. It seems such an obvious device to make, but I was unable to find ANY attempts of creating a thing like this for years. And I never got to designing it myself.

 

This is the kind of LTT content I enjoy, not some yet-another-over-the-top-build.

Do you have the ETA? Or a customizable FOSS Linux driver in mind (the linked one is closed-source and Windows-only)? I'm probably going to make and configure a deej myself, but this might become an interesting alternative.

[fireflies38]

Anyone have links for getting those sliders that are shown in the video ? Maybe Aliexpress or something ?

[dbtech]

Will you PLEASE provide the full bill of materials for the 3D printed version of it? I really want to make EXACTLY what you have there, but you didn't provide a full list of what you used.
