I think this is a good moment to write to you and your team some of my thoughts, i know that you and your team dont even know i exist, but i appreciate this enormous legacy that you have built, you are one of my biggest inspirations, i'm no engineer neither i have the biggest knowledge, but most of the things i know come from you, sometimes i dont quite understand the things you do but that does not keep me from waiting every week for a new episode from The Ben Heck Show, i even know from memory the lines of all your intros, sonce the first one and repeat them every time i see one of your videos and for me they are more than videos, i love the passion and effort you put into your work, everyone can tell that you are not here for the money, you are here because this is what you love, and we can see that in the improving through the years, your revisits are awesome and when i see you making a new version of something and see how much you have improved i see myself and i see how much, with your help i have improved, i have awesome soldering skills, y learned to love my tools, and the thing i remember the most is to "Always Build Something You Can Take Apart" i learned to solder SMD components, how to take apart consoles, i just learned so much things, i like your sense of humor and you just not giving a flying fuck and making all this cheesy quotes from movies or acting, this is more than a show for me and you are more than just that guy who does electronics stuff, your work, dedication, passion, love and genius are an inspiration to me, to my work and i thank you and your team for that, i miss Alisson but i hope she is doing great, Thank You Ben! You Are Awesome!
Ben, you're an awesome guy. You're more of an inspiration than my own father. You deserve a place in this world, just like everyone else. You are a genius, and a mastermind. You're unique in your field, you're looked upon by thousands of people; who respect you greatly. Whatever has happened, whatever you're going through, I hope you manage to make it through. I hope you're not feeling suicidal, because you're too important to leave us, but I don't want you to feel worse, or live a depressing life; thinking you've got no way out. Your life may seem dull, or that you haven't achieved "life's purpose" perhaps, but I promise that you have made much more of a positive impact on the earth than anyone else by the majority. You've already left a legacy, and you're a knowledgable man. You do a great job. I don't always acknowledge everything in your videos, but I always look forward to them. I wish you the best -

Kyle247l ??
This would be a nice comment if it actually applied, here... Otherwise, it seems like kind of a dick post in a condescending way.
Kyle247l I also have respect for Ben and think he is a great guy but why on earth would you write this? Ben seems fine? I assume he does get stressed at times too, but who doesn't. I am sure Ben's family and friends are always looking out for him and would act if they thought he was depressed to that stage.
marcoswi "under the weather", and the stress ball(?)
I think I had a few too many to drink, but I certainly meant everything I said
Alexander Cary I think I was just overreacting when I noticed the stress ball, along with the text "under the weather"... I look like such an idiot. I apologize. Hopefully this doesn't come across as condescending. Hopefully positive. Even though my comment may be totally irrelevant now, I'll keep it up anyway, because its all true; regardless of the circumstances.
That was definitely killer episode! I like that flooding technique that Ben did on the main MCU. there's a lot of tips just for the SMD soldering work. as well as designing the board in Eagle cad. Watching that, answered a lot of questions and is settling most of my anxiety about working with SMDs! :-) hehe!
I really believe that you can ditch the soldering iron and do this with solder paste a small exacto knife and a heat gun. Be stingey with solder paste and remove as much asnpossible with knife. The paste keeps parts in place when air is blowing on the board. You dont have to keep paste on the pads as the solder resist will ball any extra. You cam manually place cponents and then heat in one pass. Them turn over and repeat. If the parts move during soldering use tweezers to push into place. If they move too much you are too close. Dont be discouraged once ypu get used to air gun you will never go back to solderimg irons.
Great video. It would be nice if you could find a way that you could do the short video for the knowledgeable and a longer version or 2 that would explain more (why you had to put the caps and resistors here and why that value-and how to use eagle) for the rest of us that would like to know and don't!
Thanks again for the videos.
Awesome episode!
Staggering the program header pins for a press fit was pretty slick.
Christopher Johnson Yeah man. I never knew that was an option. I always figured it would screw with the pads or whatever. Then again, I guess you only really have to program it once hopefully).
Christopher Johnson I like it too. Any ideas as to how far apart the staggering should be? I'm guessing 15-16 mil from counting pixels in a screenshot.
For the oven reflow, was the tension of the paste really enough to hold the components on the underside of the board in place?
Ben, just for information the pickit3 can provide power to the board, if using MPLAB MPE go to Settings>>Advanced Mode click on the power tab select the required voltage and check the "Power Target Circuit from Tool", if you're using MPLAB X IDE go to Run>>Set Project Configuration>>Customize then click PICkit 3, click on the drop down at the top select "Power" check the "Power Target.." and set the level it is limited to a load of from memory i think 100mA. You can do this with the ICD as well not just the PICkit. Hope that this helps someone in a pinch.
I am a big fan of PIC, so thanks for showing us this proyect
That moment when ben is surprised it worked lol. great work again.
Great episode
Verry nice lights in the ben heck workshop!
Have you thought about drag soldering for those SOIC packages? Pretty easy (especially with your tools) and very quick.
Since this is essentially a break out PCB for a PIC32, I would recommend you add BAT54S's and SMT caps connected to analog input pins of the microcontroller. If you use the analog inputs you can install the cap and BAT54S. If you do NOT use the analog input, simply leave the caps and diodes out.
a minute and a half in and I can thank Ben for a 3 digit ping after 7:30PM every day. Thanks Ben, fix my ping ;)
What was the total cost on this build? Would love to see a parts list. Guess I'll have to re-watch slowly and take full notes.
Which of the two techniques for soldering (oven reflow or manual) gave the nicer i.e. neater/cleaner results? I am developing a board that will be fully visible in the final project.
The PICkit 3 can provide power if you enable it in the settings. Also i think it's a lot easyer to use the PICkit to programm the PIC when using MPLAB to create the programms.
What software are you using on the schematic and board layouts? Very Nice!!!
When you hint at other videoes about a subject, you should really use annotation links! Other than that, this is as interresting as always!
In the full pro paid version of eagle, are libraries automatically updated and how often? I poked around in the software free version and could not find a few of amtel's newer 144 pin microcontrollers.
Check out OSHPark. They're a fairly decent board-house, and they'll make your boards fairly cheaply too. I've used them for all my projects, and they haven't failed me yet.
Nikolaj Lepka 2nd
Nikolaj Lepka he's sponsored by element14, if he does advertise with another trademark, it is like... bad for his sponsor right?
remace07 I know, I didn't deny that. I was just saying what I recommend myself as an alternative to what he says.
Nikolaj Lepka Trouble with OSHPark is that the price ramps up rapidly with board size. Over a certain PCB size, Itead or dirtypcbs is a more economic option.
Nikolaj Lepka I use PCBway. So much cheaper than anything I have seen. Only downside is it comes from China.
wow a surprise, the video rather than a trailer
The Ben Heck Show Will these schematics be available somewhere? Can't find any info on ur element 14 page...
***** The Ben Heck Show : IS USB Type C available when making custom boards? Are newer ports more expensive?
I'd like to know too!
***** you can get USB-C connectors at Digikey www.digikey.com/product-detail/en/898-43-024-90-310000/ED1391CT-ND/5213140
I remember my first time with a soldering iron. It was not pretty. The first thing I learned was to leave well enough alone and keep a rhythm. Now, though, I think I could attempt surface mount.
Star Trek 3 was basically a remake of Spock's Brain, with I guess Genesis as the MacGuffin. And, lo, the odd number rule was born. No whales or Moby Dick references to prop it up. But the Enterprise blowing up was cool.
No, PIC stands for Peripheral Interface Controller (Microchip) or originally by GI, which was bought by Microchip, now it's Programmable Intelligent Computer. See Wikipedia.
Isn't the bottom layer in Eagle blue, not purple?
Hey Ben good to know you are responsible for the response time for games and joypads :-)
A friend of me was complaining about project cars for ps4 that the controls are terrible.
He tweaked some settings but it's still not good. Are there some tips for him?
Thanks in advance for the PRO tips ;-)
Hello Mr.Heck I was wondering wen can you do a built of a ps4 laptop or a handheld ps4 system that would be a great build and new challenge to try and discover
I was just wondering ps4 or xbox one if he can built one that be super cool if he would
daniel foster He already did XBOX 1
Ok he can least do ps4
Ben, the pickit3 can actually power your board.
Do they actually use a silkscreen? Or are they printed some way?
New camera? Or higher FPS?
why dont you try out arm? The stm32 series are great and cheap :) And also very beginner friendly because it can be programmed over the arduino ide
Hey Ben, which program that you are using?
How can you reflow something where there is stuff on the back? Wouldn't it possibly fall off?
What does Ben use Inkscape for, if he has Adobe Illustrator?
did someone done building the develepment board with this show?? can someone share the shematic or sell??
I try to do what you can do soooo much and fail. Great job :-)
It's funny. Andre LaMothe, in The Black Art of Video Game Console Design, says that the best way to avoid problems when soldering surface mount chips, is to solder each pin, one at a time, yet the two people I watch online (Ben Heck and Dave from EEVBlog) say to avoid that.
No screw holes in the board to mount it to your project? Sometimes hot glue is not appropriate for holding PCBs into cases... Other than that, nice project.
Treasure Pirate it depends, I think screw holes may add cost.
a person could design their cases with a ridge to hold the boards in place without the need for screws.
or failing this, hot gluing a board into place usually does work, though with the caveat of not using hot glue around components which may get hot (such as transistors or voltage regulators, as the components will melt the glue), nor around places where one may want to solder later.
Brendan Bohannon That is a good point on cost. Still, for those of us that don't have 3d printers, finding a case with ridges that just happen to fit a board that we designed from scratch is probably a long shot. So I would prefer the slightly extra cost of a couple of mounting holes to having to spend extra time and money finding a case that fit just right. Thanks for the discussion.
Treasure Pirate
possibly, though Ben has a 3D printer and has in the past made cases with ridges for holding things. I guess these were mostly for personal use on his part?...
in my case, my brother got a 3D printer for $400, and it is pretty nifty and useful, though it doesn't (at least with the stock firmware) do nylon, and ABS doesn't make for very good gears (they wear pretty bad and don't really handle higher power-levels without grinding to dust or turning into plastic cheese). solid parts are generally pretty good though.
also working on (eventually) trying to get a CNC milling machine made mostly for wood and metal parts (mostly held up on making the box for it).
in my case, most of my boards are made on perfboard though, so mostly through-hole and running wires place to place (recently, I got some 24 and 28 AWG magnet wire for this, which is more-or less good, with some 20AWG mostly for running power traces).
though, sadly, yeah, most modern digital components are only available as surface mount. it is ok, as most of what I am making is mostly power electronics, which is still mostly through-hole (typically, the controllers have been on separate boards).
you should do an episode making a jtag setup
***** you mentioned wanting a Pick in Place maching, just found a DIY kit(yes I know there are probably others) www.liteplacer.com as seen on EEVblog
The Ben Heck Show Can you make a video of how to make a homemade PIC progammer?
The boards were really expensive, whats the cheapest way to make pcbs? I was wondering if one could print onto aluminum foil and then glue it to a plastic board and then etch it.
I can't imagine you'd get good adhesion from the aluminum to the plastic that way. Sure you can etch your own pcb, but how far are you willing to go to save a buck. Not to mention how time consuming it is to drill tiny holes for through hole parts. $20 is not huge price to pay in the grand scheme of things for a custom pcb.
I found this, and personally, as a college student with lots of time, and little money, i would rather make my own. www.instructables.com/id/Sponge-Ferric-Chloride-Method-Etch-Circuit-Bo/
What was the cost per board? Atleast $20, right? Also, how does this one stack up against similar items on the market?
20pcx for 20dollar each. So 400 dollar? realy?
metanulski That is a lot of money, I can order those 20 for 30$ max inc shipping. But you need to wait 2/3 weeks...
TGHstudio id rather wait 2-3 weeks for 20 boards than a month or so
metanulski Check out dirtypcbs.com
IIRC the ps1 used the pic32 for a bit of modding.
what program is he using for the PCB design and circuit?
Mateus Marcuzzo eagle it can be downloaded from element14
Simon Heij Thanks.
And the second one, red, that remembers arduino IDE?
How big is your monitor it looks huge
is there anywhere we can get the eagle file?
Why don't the parts on the top of the board fall off when you reflow the bottom side? Is the surface tension of the molten solder that strong?
I'm surprised that you still favor the mini USB over the Micro. There IS a reason why the industry has switched. The Micro size has a bit smaller footprint (maybe not enough by itself to justify the switch but ...), but it will withstand more plug insert - removal cycles. Note that the retaining spring for the mini is part of the jack, while on the micro it is part of the plug. So when the spring wears out (they WILL) the mini jack is toast, while on the micro you just get a new cable. Better to replace the cable than operate on the board!
how much does eagle software cost?
New camera?
That means your also partly responsible for when my game lags due to high latency! xP hehe
Yay ... another devboard doing exactly the same as the 9999 others around for that chip.
$18 EACH? As in, for each board? With nothing on them? Are they handmade?
I have no experience ordering boards online, but I always figured you'd be paying maybe a couple bucks for something this small. Are there ways to get them cheaper, like ordering 1000 and waiting longer? Maybe through another service? This seems prohibitive for a hobbyist developer.
Great video!
What is with the blue ball in your hand?
***** First part: information, 2nd part: personal choice :)-
ok i understand now boob ball
That's pricey for PCB's OSHpark is much cheaper, at least from my last order. Too bad they take a couple of weeks to get in.
Just checked out pentalogix site and they have an overseas option, very cheap! Will be trying them out for my next project.
Liked because of this phrase"I'm against micro usb so i want my mini usb"
The PICKit DOES provide power! in MPLAB IPE go to advanced mode, enter "microchip" as the password, and under "power" you will find "power target", and can even select the voltage.
Hey! Ben you should teach us how to build a mini but powerful next gem gaming pc!!!!!!!!
Ben Heck can you make a 2 Terabyte hard drive?
can you build a ps4 and a xbox one in one case
I didn't like Into Darkness either.
10:18 Who else thought PCI Express?
Come on Beck
I won't suggest using solder wick because one could rip off the pads if not done properly. It is easier to use solder flux and do wave soldering. That's what I recommend.
Can a GPU be Heck on?
Wick ed, forgot wicked
Ben, I love your show, but you need to like adjust your volume levels so that they match your ads. Element 14 comes on blasting techno in the middle of your show, and it's like twice as loud, and it's kinda annoying.
Rando can you send me link to it lol
Pick32, not PIC32, in the description!
***** do not pick pic and all will be ok )
***** I think your wrong.
marcoswi typo fixed already
yeh
6:50 why did you feel it was important to tell us your printer is $200
Jared Reabow He is showing us how a tool WE normal tinkerers can afford allows him to do things that his 20k tools can't as easily do.
Dave McAnulty i disagree for $200 his printer must do something myne does not....thats a HUGE amount for a printer.
Jared Reabow it's about right for a color laser printer. Maybe a cheap HP or higher end brother/samsung.
Jared Reabow He probably bought it a few years ago (read: over a decade ago) before they became basically throwaways.
13:00 USE A FUCKING 3RD HAND
unnah three hunnah
PLEASE CALL SOLDER SOLDER AND NOT SODDER
220th
who would spent 400$ (and even more for shipping and taxes) for 20pcs of these really small pcb? and they are only 2 sided!
how much did they pay the show to advertise them that way?
Nice work... Microchip Arduino.. the war is on..?

solder wick is coax braid wannabee
Pic is nice but Linux support sucks. AVR all the way!
Hi Ben
It is embarrassing to see you solder. It is unprofessional. While you're getting your money from Farnell, I wouldnt put that kind of work online. But nice project.
