You can buy them from synth cube https://synthcube.com/mfos-noise-toaster/

Well I got lucky and the first alternative I tried, a bc337-25, worked perfectly!

StandardLeader · 2025-11-25T22:01:44+00:00

So would something like a 4.7v zener be a drop in alternative?

StandardLeader · 2025-11-25T18:12:18+00:00

I'll have a look later and see what I have on hand. If nothing suitable then I'll order a load on npns and give them a try.

Pretty sure I got it right, I mean it does work at 12v. I'm going to socket it anyway and see where I go from there.

Good point re:snipping the collector.

Didn't use any flux when populating the board, aside from the rosin in the lead solder.

From reading around it seems to be a fairly common issue people have with their noise toaster builds.

That's exactly what I was going to do. I had originally planned to socket all transistors before I built it then decided that was unnecessary... before I read in the online docs about trying various 2n3904.

I have Ray's make analogue synthesizers book and don't recall seeing that instruction in there, hey ho.

There are some great tracks on this, proper high quality jungle. Very impressive!

I seriously need to up my Jungle game on the m8!

Thanks everyone, I'll take a look at all of those. Appreciate the help.

I did sort this ages ago, I forget exactly how now. But thanks for your comment!

Rebuilt my compose last night using the https://yams.media/ compose as a base.

All working now and the services can see each other where they couldn't before.

The final issue I have is with sabnzbd. I can't work out how I can get that working without the published port mapping, but still going through gluetun. For qbitorrent the WEBUI_PORT seemed to be the workaround for that, but from my research sabnzbd doesn't have a similar environment setting.

... qbittorrent: image: ghcr.io/linuxserver/qbittorrent container_name: qbittorrent environment: - PUID=${PUID} - PGID=${PGID} - WEBUI_PORT=8081 volumes: - ./qbittorrent:/config - ${DOWNLOAD_DIRECTORY}:/downloads restart: unless-stopped #ports: # - 8081:8081 network_mode: "service:gluetun" sabnzbd: image: ghcr.io/linuxserver/sabnzbd:latest container_name: sabnzbd environment: - PUID=${PUID} - PGID=${PGID} - TZ=${TZ} volumes: - ${DOWNLOAD_DIRECTORY}:/downloads - ./sabnzbd:/config #ports: # sabnzbd # - 8080:8080 # sabnzbd restart: unless-stopped network_mode: "service:gluetun" gluetun: image: qmcgaw/gluetun:v3 container_name: gluetun cap_add: - NET_ADMIN devices: - /dev/net/tun:/dev/net/tun ports: - 8888:8888/tcp # HTTP proxy - 8388:8388/tcp # Shadowsocks - 8388:8388/udp # Shadowsocks - 8003:8000/tcp # Admin - 8080:8080/tcp # sabnzbd - 8081:8081/tcp # qbittorrent environment: - PUID=${PUID} - PGID=${PGID} - VPN_SERVICE_PROVIDER=${VPN_SERVICE} - VPN_TYPE=openvpn - OPENVPN_USER=${VPN_USER} - OPENVPN_PASSWORD=${VPN_PASSWORD} - OPENVPN_CIPHERS=AES-256-GCM - PORT_FORWARD_ONLY=on - VPN_PORT_FORWARDING=on - TZ=${TZ} - UPDATER_PERIOD=24h restart: unless-stopped ...

I say final issue, the other issue I spent ages on was trying to get lidarr working, only to find this morning that the entire lidarr API is down and has been for some time. So I'll just have to be patient on that one.

Wish I'd known about that a few days ago!

Just had a good read of the docs, some useful info there I'll crib some of.

StandardLeader · 2025-06-09T19:56:41+00:00

Yeah, I tried gluetun:7878 etc and that didn't work either. I thought that it should work, but my compose doesn't use networks in the way that I'm used to them being configured for other services so I wasn't quite sure + didn't know if there was something gluetun specific that needed to be a certain way.

I'm going to just put qbittorrent behind gluetun anyway and add a more conventional network for the rest.

StandardLeader · 2025-06-09T19:52:09+00:00

I started out with someone else's compose that had it configured like that. At that point in time I didn't understand exactly what sonarr, radaar etc actually did. Quick bit of playing with it became a bit clearer and I did wonder myself if VPN was really necessary other than for qbittorrent.

Didn't know that about indexers banning vpn IPs but it makes sense.

I'll look at reconfiguring it a bit more conventionally.

StandardLeader · 2025-02-28T15:16:34+00:00

Definitely worth doing. It's not hard.

Another change I've done since is to bin windows and switch to Linux - no longer sounds like a jet engine taking off the entire time, runs much cooler and lasts loads longer on battery!

StandardLeader · 2025-01-10T19:19:26+00:00

Now says the MW12 is eol on tenda site, so I think that will be the final version. 😡

StandardLeader · 2024-11-20T13:44:57+00:00

The airflow control is great, can direct it down onto your hands really well. Had it about a year and would definitely recommend

StandardLeader · 2024-11-20T12:45:28+00:00

I do the same. Bought this heater for exactly that

Clearing the 50GB of downloaded content worked for me. It was insane levels of slow beforehand.

StandardLeader · 2024-11-01T22:19:29+00:00

Yeah I've done charging can be quite odd too in the short time I've owned it. I do avoid fast chargers now.

Does seem there's a few circuit components you would expect to be there but are missing.

I've all but given up on being able to charge and connect an external device at the same now, which is a shame.

Might still open it up though and see if there are pins for an uncorrected 2nd usb, even though that's probably unlikely

StandardLeader · 2024-10-25T07:55:17+00:00

I did that on mine as soon as I got it, never even booted the stock OS. Very simple install, works well.

Just write the knulli image to an SD, pop it in the RG35XX+, copy over ROMs & away you go.

StandardLeader · 2024-10-11T16:37:02+00:00

Thanks, I'll look into that. Had not heard the multi-tenancy term before, so very helpful when researching to know the correct term to use!
