Thanks for the reply Ralph. To confirm, the voltage drops only when I start checking it with the DVM between the blower jack "+12V" and the ground pin on the jack. The +12V pin/hole in the board stays constant at 12.5V when using another board ground with the DVM. Another 'symptom' is that...

Hey guys, So have my old v4.0 board working pretty good except the blower doesn't work. I tested it by hooking it up direct to 12V and works good so must be something on the HM side. Some things I've tested so far: - checked the various 5V and 3.3V on the HM board using an old diagram I...

So turns out I found the diagram in an old post I made many years ago! I will check these few points here in a bit. Any advice on other troubleshooting to do for this old v4.0 girl is appreciated. Cheers,

Hey guys, Finally have my old v4.0 board and zero W combo working. Boots up, connects to wifi, reads probes, all good. No love for the blower though, and only see 0.15v or so on the blower output with blower at 100%. I'd like to do a voltage check on the board but I can't find the old v4.0...

I have an old Pi 1 Model B and was trying to use Edimax Wifi dongle. I actually just hardwired this morning to eliminate that as an issue. Something else is up and I'm pretty sure just my Pi is messed up. Did a fresh SD card image and watched the log.. lots of USB errors, and eventually just...

So I think an issue might be that the USB ports don't seem to recognize the keyboard (no matter what I use). They may not work at all (not sure how to check). This may be a busted Pi in some sense. I tried flashing Rasbian Lite just to check it out without the HM, and it installed OK but...

Thanks Bryan, I was wondering if there was any way to export the log but a picture is my only option eh? It does't all fit on the one screen so I'll try to be quick and get some of the earlier entries as well. I will also try a different keyboard, though unfortunately it is the only wired...

Hey guys, Trying to resurrect an old V4.0 board. Loaded the latest snapshot (I want to use wifi dongle) and all seems to go OK when I boot for the first time, but it hangs after 200 seconds on "random: crng init done". I cant' seem to do anything. I've read sometimes just 'hitting Enter'...

Ralph, thanks very much for the info on how you fixed your ET732 probes (soldering a little wire from the braid to the shaft). I was having the exact same intermittent / dropping out issues as you describe. Would have been pulling my hair out big time trying to figure it out if it hadn't been...

Answered my own question but just 'doing it'.. that is indeed what needs to be done, thermistor should be soldered to the two holes at either end of the footprint.

I'm not sure what number we're at now.. if Dale is 83, Peter and Chris are 84 and 85, makes me 86. Just did my first 'cook' with it last night (not low/slow but works dandy for higher heat too!)

Just to follow up on this.. soldered in the new IC3, doubled checked that solder had flowed to the other side of the board, and fired it up... to have no lights, nothing! Turns out, when I went around resoldering I bridged two pins on the voltage regulator! Luckily I noticed and was able...

I have the same issue, no jack installed. I have the thermistor soldered as shown in this picture: Are you saying I should have soldered one pin of the thermistor to the larger hole and not the one on the long edge of the footprint? Thanks

Thanks Bryan, sounds like not running in "Sous Vides" mode (min/max to 100%) would be a bad (or potentially bad) idea when driving an SSR. Am I able to set the fan speed manually 'and' have min/max set to 100%? This would mean I'm driving the SSR a little more appropriately yet able to control...

You've lost me here for sure.. I know if I set min/max fan to 100% I can get it to control the SSR / element when acheiving and/or maintaining the mash temp. When you say "running at the normal 500hz" you mean sending a PWM signal to the SSR which would potentially heat up the SSR? If I try...

Thanks for the heads up. That sounds like it'll work great for the sous vides, but not sure in the brewing environment they'll last as long. I wonder if I can seal up the connection to the 'braided cord' with something high temp (epoxy? JB weld) to make them last. Cheers,

Thinking about using my HM for Sous Vides, and for controlling an electric homebrew beer setup (240V SSR). Couple of questions: - not sure the ET-72/732 probes will play all that nice with water.. would it be possible to make your ones own probes with an equivalent thermistor (and maybe...

Thanks! I have a new IC3 on order (ya.. it's pretty tough for a non-pro to remove a 16 pin IC, I used braid, flux, patience.. then gave up and clipped!). Once it comes in, will solder it in correctly, make sure the solder has flowed to both sides at all spots, and checked all the resistor...

Hi Ralph, I agree, that IC3 looks to be flipped, shoot! I did understand the directions and tried to install it the right way. Looks like I may have messed it up in the process of 'bending the pins' in a bit to get it to slip into the board. As far as the resistors, my order came with two...

Thank you VERY much, this is great stuff. I'll be sure to take your excellent advice and give it another go. I was fairly quick with the soldering of the socket/IC because I didn't want to overheat anything (and it seemed really easy to get solder to fill the bottom side, but not good enough...
