I’ve worked at two Menards stores but I had gotten into stereo/hi fi equipment between my stents at the two stores and so when i started working at the second store, the electronics really caught my eye. Of course I never bought any but I was tempted just to see how crap they were. Now I don’t have to because I discovered this channel!
Mr. Heck, just wanted to say thank you for being an inspiration for the past 10 years, I found you back in 2012 while in HS. Thought what you did was neat but I wanted to do software. 10 years later, I still think what you do is neat and last week I managed to get a soldering station and accouterments, you along with a couple others convinced me that I could learn to solder, and last night I was able to install a mod into my PS1. Thank you for being around and for doing what you have to inspire me and I am sure many others.
I like how they went out of their way to not only NOT include the isolation between AC and DC, but even left an unused pin between the AC connector on the PCB as a spark gap....
This would be a great emergency radio. Takes a ton of power options, radio range.... Holy crap. How is that mains even legal??? That has to violate some US safety code.
That's what I was thinking. I have a crank radio. When you've got nothing to do turning the crank keeps you busy. Gets your mind off the disaster you're in. It's gotten me through a few hurricanes.
While I'd hesitate the use the word great for a radio like that it *does* look like it could be useful, with some modifications. The very first thing I'd do is rip out that mains plug port so that never gets used! Next is take a closer look at the chips to see what they're capable of and if there's some unused functions that could be brought out/exploited.
It's not the capacitor limiting the voltage, it's the SLA battery. If you removed the battery from the circuit, the voltage would shoot up until something went bang. The polypropylene film capacitor is there to limit the current, not the voltage. In a capacitor dropper, you need something to clamp the voltage, in this case it is a SLA battery, but you can use other things like LEDs or zener diodes. Not that I'd recommend using a capacitor dropper in something like this ever. The only place it has a use is in sealed devices like LED lights where you can't come in contact with the mains.
They obviously didn't do it here, but you can also use a capacitive dropper to drop the output of a transformer if you have the wrong ratio, getting the safety of a transformer supply at the cost of reduced output current.
This reminds me of the death "dalek" flashlight that Big Clive tore down a few years back. The handles and USB output port were live at mains voltage when charging.
R37 is to discharge the cap when the mains is off, the capacitor limits the current, and the lead acid battery limits the voltage. If you have the mains lead in, then all metal connected could be live! - this is a death trap! When plugged in - it breaks so many rules.
Capacitive dropper, gets quite hot under load and is quite inefficient. The lead acid is clamping the voltage, until the electrolyte dries up. Then it either opens up, which causes the voltage to reach line level, or it shorts out, likely causing the orange capacitor or the resistor to catch fire. You can safely charge lead batteries at C/10, float them at C/20. So let's assume middle of the road, that means it takes 15h to charge the battery, if you're not using the radio. Judging by the size of the battery and parts, no more than 100mA are flowing through the 'regulator', but the radio likely draws more current at high volume. The battery could be used as an UPS for a Pi, since you can just feed 5-5.5V into it.
A capacitive dropper is quite efficient because the capacitor returns the energy on the next half-cycle. It's resistive droppers which are inefficient.
You'd be happy to know that many brand new buildings still have their emergency lighting fixtures/circuits/inverters powered by lead acid batteries. Fire alarms and security systems too. They get replaced at regular intervals (or are supposed to), and are very reliable and robust in an application like building emergency systems. In the old days (or if you ever went into a Kmart) if you looked at their emergency lights from the '70s, they would often take a whole car battery and sometimes had an additional battery mounted around the side of the pole. Not only that but the lights themselves were basically car headlights. They have to run for 90 minutes.
Army Hammer's father was Armond Hammer. The company was first made public a few years prior to Armond's birth. Armond was ridiculed much of his life because of the name. He also became a board member of the Arm & Hammer company!
There is/was no "Armond Hammer". Actor & cannibal Armand "Armie" (not "Army") Douglas Hammer is the son of Michael Armand Hammer who in turn is the son of Julian Armand Hammer and the grandson of the industrialist Armand Hammer. So we are talking about four generations of Armands here... Industrialist Armand Hammer was - according to Wikipropagandia - a true communist and "Lenin's favorite capitalist". He actually didn't sit on the board of "Arm & Hammer" as this was only a brand and not a company. Wiki says: "In the 1980s Hammer owned a considerable amount of stock in Church & Dwight, the company that manufactures Arm & Hammer products; he also served on its board of directors. However, the Arm & Hammer company's brand name did not originate with Armand Hammer. It was in use 31 years before Hammer was born. While Hammer and Occidental said that the Church & Dwight investment was a coincidence, Hammer acknowledged previously trying to buy the Arm & Hammer brand as a result of often being asked about it." People interested in that clan should read the Wiki entry on Armand Hammer. Interesting fella. en.wikipedia.org/wiki/Armand_Hammer

The only side-effect i get from watching your video's is i find myself smelling random electronics more often than i used to 👍 Edit: New camera mount seems up to the task of not making me puke (not that the last one did, but yea, good cam angle)
I got to enter Wisconsin for the first time last week (Chicago trip)... so I petitioned the wife for a visit to the Menards in Kenosha, solely based on these Ben Heck videos. That place is pretty neat, but I wasn't able to locate some of the cooler swag that Ben seems to find. Maybe I was in the wrong sections. (Also, House of Gerhard was delicious. If we didn't eat there, my first Culvers experience would have happened. Maybe next time!)

The 18650 fit may be due to protected/unprotected cell lengths - protected cells are slightly longer. Also there's the issue with nibs versus flat-tops. Edit: Commenting as I'm watching - OMG, capacitive dropper on an object with exposed inputs/metal? WTF. Edit 2: Maybe they're doing a push-pull configuration on the audio amp.
6:49 There is was a guy named Armand Hammer who did serve on the board for the company that made Arm and Hammer baking soda. As a note, the product was named before he ever was born.
That's a capacitive dropper. You should watch Big Clive's analysis of camping light with this kind of PSU, they're dangerous, you can get shocks from some metallic parts like the USB plug, or the battery spring contacts
The AC in looks like its going to a capacitive dropper? I wonder if theres any leakage to the DC side? The odd range of power options gives the impression it might be for use in developing countries?
It doesn't matter if there's leakage or not, it matters if the cap is on the Live or the Neutral side of the unpolarized plug. If you flip the plug so that the cap is on the Neutral side, then everything that is on the 0v rail will be almost directly referenced to live - the metal on the micro sd card slot, the ground on the line in... fun times for everyone using it.
@@barbudoru : You forgot to mention that sometimes the outlets are wired backwards (especially on reworked areas), so that live & neutral are switched.
The people designing this must have seen these power supply teardown videos where electrical engineers point out how crappy and dangerous these cheap PSUs are and thought "Can't be crappy and dangerous if there IS NO power supply!"
It's a capacitive dropper, I believe if you plug it in backwards you get half wave rectified mains on the ground/shielding! On a device with a figure 8 plug... Fucking terrifying
I now need a series of Ben making a collection of ineffective cat distraction devices. Sounds like great fun, then you can wander around the house with the camera to find and attempt to entertain the cat, only for him to sit there and look at you with mild disdain.
Hot chassis! Never ever connect anything to the circuitry. Especially if you like life. I didn't notice if it was UL listed. Definitely a shock hazard the negative of the D cell battery terminal will be 70vac above ground.
I spent 2 weeks in the hospital recently, When I finally got back home I was still taking morphine, was looking forward to space out in my couch and watch a new Ben video, but then I was introduced to the Puke-cam (TM)… It almost got me 😂
I bought a version without BT, but it also had a Shortwave tuner! I tore it apart after seeing your vid, and... yep. Lead-acid battery. I later got a better shortwave device off of Amazon lol Greetings from Wausau!
Send that to Big Clive. He can tell us how naughty it is while he draws us the schematic. :D It's more surprising you found that in retail and not from AliExpress. You can charge lead acid that way - I found many emergency lights that do it by just floating it- but not in such a crappy way!
This is great free advertising for Menard's. I live on the east coast, and have never heard of it before. Now if I'm Menard's open near me, I would probably check it out because it's the store you get all this fun stuff from. The Menard's people should cut you a check.
there is a lot i didn't like about living in the midwest, but these videos do remind me how great menards is. going to menards on route 66 is a unique experience (i used to live just off of route 66). i noticed that new businesses built "on route 66" were actually built about a half block away with weird short roads that act like a driveway to get into the parking lot. i figured this has something to do with the preservation and historic status of the road. locals couldn't care less about route 66 though, and most never even realized they were on it because the name changes about 1000 times
They're using a capacitive dropper to charge the lead acid battery from mains. It's an acceptable way to do so for lead acid but still pretty jank. A linear transformer at least would make it much safer. The issue is that it's not isolated from mains this way. The lead acid batteries with capacitive dropper circuits are common in old rechargable flashlights that plugged directly into the outlets to charge. It's really not worth $30 at all, not even close.
The whole reason this type of crap exist is because someone had a warehouse full of led acid batteries and wanted to get rid of them. At some point China would start shipping this kind of tat with compartments filled with pressed landfill plastic or medical waste.
Perhaps the RF tuner doubled as a variac transformer. 120v @ FM 88.1 and 12v @ FM 107.9. I'm pretty sure the safety was in the 45awg mains line aka 50mA inline fuse. Tis but two sweaters touching Christmas morning.
The battery is actually the best safety precaution that has been taken on the device. Unlike lithium-ion batteries, they tend not to burst into flames wen overcharged (and they also last far longer than NICD batteries).
(2:10) I KNEW you'd mention Techmoan! (5:34) Yeah, you can tell it's cheap, because the 2 flat parallel prongs with no holes like those look to me like plugs for China, not North America!
You could tell it was lead acid, because of the cap on top. I'm surprised they mounted it sideways, though. It almost looked like there was a way to get at the cells, to add water. The waffle grille was right behind the "X-Bass" sticker. Maybe it was a crude port of some sort. Maybe, it was actually going through the motions to be functional, but not necessarily helpful or useful. The C battery holder was confusing.
They've even included the flashlight to light one's way up to the pearly gates. Just a guess: What's the USB port voltage while charging? I bet it's not 5V..
My dad was in basic training during WWII with a guy named, I kid you not, "Captain John Smith". First name was Captain. So he was Private Captain John Smith.
Armie Hammer's great grandfather was a business magnate named Armand Hammer, and Armand Hammer eventually bought a controlling interest in company that owned Arm & Hammer, apparently in part because he was tired of people asking if there was a connection between him and it.
I had this all in one charging emergency radio kit I harvested for it’s dynamo that was almost this bad, as it had a lead acid battery, and a really janky method of joining all the power sources (though it didn’t have “mains” voltage)
Can't you press multiple analog-multiplexed buttons at once if you use resistors of exponetial values, specifically each resistor is twice the value of the last? Would work like a resistor ladder but in reverse - each button would correspond to a specific bit in the ADCs returned value. But you would need very precise resistors as well as extra bits of ADC resolution versus amount of buttons (e.g. a 10-bit ADC for 7 or 8 buttons). To read it, bitshift the ADC value rightward by the ADC resolution less the amount of buttons (psuedo-code example: ADC_Value >> [ADC_Resolution - Button_Count]) then you have a bitmask of buttons pressed.
Was that leaded solder as well on the pcb. That this is a fire hazard I didn't see a fuse eighter not that it matter the mains wire so thin should act like a fusible link
The capacitor is a part of a "Capacitive dropper" - It's a way to drop the voltage without too much loss. The battery (and maybe a zener) is pulling the voltage down.
This looks like something someone imported from China 10+ years ago and forgot about in the back of a warehouse for a while, haven't seen something this junky in while... hard to believe this was designed in late 2020... I guess they're running the amp chip in bridge mono and the speakers in series because the capacitor dropper power supply was too weak to run stereo 4 ohm speakers at a decent volume
That was an awesome post apocalypse Fallout radio. You'd never be able to plug it into line voltage then. So that's that problem solved right there. I don't think connecting speakers in series is uncommon. Keeps the impedance high.
How does one get in touch with "Big Clive"? I'd be happy to snail mail him one of these across the pond.
Then you would need to get the radio in the pink version!
I'm pretty sure it would be really easy since he spends about 18 hours a day on correspondence.
Just say "Big Clive" 3 times while looking at your reflection in a blob of solder

I was thinking this was going to turn into an Electroboom video.
Consumer: "Hmmm, it's pretty heavy, can't be that cheap"

holy shit I'm crying.
I've seen enough Big Clive teardowns to recognize the capacitive dropper on mains. If I recall, the shield of the USB will be live at mains voltage.
Yeah, i believe if you plug it in backwards you get half wave rectified mains on the shielding. On a device with a figure 8 plug...
Headphone jack too.
any product with shiny black plastic and chrome buttons just gives me the "too cheap to be a serious product" vibes, by default

The battery is actually the best safety precaution that has been taken on the device. Unlike lithium-ion batteries, they tend not to burst into flames wen overcharged (and they also last far longer than NICD batteries).
Yeah, don't they just produce hydrogen gas when overcharged?
(2:10) I KNEW you'd mention Techmoan!
(5:34) Yeah, you can tell it's cheap, because the 2 flat parallel prongs with no holes like those look to me like plugs for China, not North America!
You could tell it was lead acid, because of the cap on top. I'm surprised they mounted it sideways, though. It almost looked like there was a way to get at the cells, to add water. The waffle grille was right behind the "X-Bass" sticker. Maybe it was a crude port of some sort. Maybe, it was actually going through the motions to be functional, but not necessarily helpful or useful. The C battery holder was confusing.
Lead acid battery, class AB amp chip, capacitive dropper, this thing is OLD SCHOOL!
For the solar panel input, are they relying on the fact that a small solar panel won't put out much current and thus the voltage will be dragged down?
I believe so.
Probably intended for one of those little 1W panels.
Everybody Loves Raymon, your favorite show
They've even included the flashlight to light one's way up to the pearly gates. Just a guess: What's the USB port voltage while charging? I bet it's not 5V..
AWESOME. Glad you're fixing the overhead camera angle issue. Thanks! :)
Edit: I haven't laughed this much on one of your videos in quite a while. XD
Feels like a whole different channel without the puke cam. Never bothered me, but it does look a bit more "natural" now
Thanks for changing you camera setup.
Whenever I hear the phrase 'bugger all' from someone outside the uk/aus/nz, the world seems a little bit brighter.
My dad was in basic training during WWII with a guy named, I kid you not, "Captain John Smith". First name was Captain. So he was Private Captain John Smith.
I appreciate the white balance fix at the 6 minute mark.
Armie Hammer's great grandfather was a business magnate named Armand Hammer, and Armand Hammer eventually bought a controlling interest in company that owned Arm & Hammer, apparently in part because he was tired of people asking if there was a connection between him and it.
That antenna might look good on the cyber deck too
Thanks Ben. A pleasure as always. :)
I had this all in one charging emergency radio kit I harvested for it’s dynamo that was almost this bad, as it had a lead acid battery, and a really janky method of joining all the power sources (though it didn’t have “mains” voltage)
I always listen to JJO when im near Madison!
Pb. I love it. It doesn't catch on fire like today's offerings
Can't you press multiple analog-multiplexed buttons at once if you use resistors of exponetial values, specifically each resistor is twice the value of the last? Would work like a resistor ladder but in reverse - each button would correspond to a specific bit in the ADCs returned value. But you would need very precise resistors as well as extra bits of ADC resolution versus amount of buttons (e.g. a 10-bit ADC for 7 or 8 buttons). To read it, bitshift the ADC value rightward by the ADC resolution less the amount of buttons (psuedo-code example: ADC_Value >> [ADC_Resolution - Button_Count]) then you have a bitmask of buttons pressed.
108.1 KCUF, we're one backwards fu...... Thanks for the video.
Was that leaded solder as well on the pcb. That this is a fire hazard I didn't see a fuse eighter not that it matter the mains wire so thin should act like a fusible link
Man, that thing is nuts. Curtain-burner AC cord?!?
Yep that big fat gumdrop is used as a capacitive dropper, I haven't seen that THING at my local Nards,
Wow, you have to call the store and tell them to take them off the shelf. That device is hazardous.
That's what I'd call a 'boom-boom' box.
Ben, I swear between you, Found Footage Fest and MST3K I will need to visit a Menard's some day.
Big fan of the new camera angle. The lead acid battery is just retro now
The capacitor is a part of a "Capacitive dropper" - It's a way to drop the voltage without too much loss. The battery (and maybe a zener) is pulling the voltage down.
There's nothing like eating pizza and enjoying some Ben Heck with menards "crap". Always a thrill.
Looks much better. Doesn't look like I'm looking out from under an airplane before a landline.
What was the little blue thing on the board? Also, I liked the old camera angle
Wow, love that Ben sang Sonic Boom from Sonic CD. 😁 Also, this radio is crazy bad!
This looks like something someone imported from China 10+ years ago and forgot about in the back of a warehouse for a while, haven't seen something this junky in while... hard to believe this was designed in late 2020...
I guess they're running the amp chip in bridge mono and the speakers in series because the capacitor dropper power supply was too weak to run stereo 4 ohm speakers at a decent volume
That was an awesome post apocalypse Fallout radio. You'd never be able to plug it into line voltage then. So that's that problem solved right there. I don't think connecting speakers in series is uncommon. Keeps the impedance high.
Hey it's not all bad ... it's got 2 way speakers ... (Ben opens it up) ... what was i thinking...?
Ben Heck & Techmoan, that would be a great collab!
Oh no you took it apart! I would have loved to see Techmoan reviewing it first.
