Do-More PLCs and Basic Ladder Logic
I love the crap out of Automation Direct for their cheap priced industrial hardware. I have saved so much money in my life going to them vs. Granger or other industrial suppliers. No they are not paying me for this... But I think if you are wanting to play with a PLC for a simple project there is no better place to look than Automation direct!
Here is a link to the Do More PLCs discussed in this video www.automationdirect.com/do-more

Cheap Current Limiter for MOTs and Old Equipment
Просмотров 4486 месяцев назад
if you are working with non current limited transformers or older hot chassis radios this is a great way to limit current to a load. THIS WILL NOT PROTECT YOU FROM SHOCK OR DEATH. It will however protect equipment from catching fire in most cases for testing. Make at your own risk yada yada yada.

Altair-Duino: The Altair 8800 You can Build!
What is the execution speed like compared to the real Altair?
The Gigatron TTL as the name implies should be implemented with TTL chips (74LSxx) not 74HCxx or 74HCTxx otherwise it is not a TTL Microcomputer anymore!
Your display panel looks cleaner than my original. Built mine in the summer of 1975.
Can you interchange the wheels on a shark Detect Pro with an Shark Ion
Fixed mine…wasn’t dirty at all like the video. I started using a t20 bit but an Allen wrench worked best because some of the screws are deep in the housing.
Was thinking about those wheels and how much they have inside the gears and hub
That's exactly the spot where my Spot Bot's hose broke
Same here
Thanks, dude! Had half a toothpick somehow lodged in the wheel well, your instructions got me there in a second. 10 mins for the fix!
It's a fun little kit! Finishing up mine now. I bet you'd really like the new PDP-11 kit from Obsolescence Guaranteed!
Thanks for documenting all of this. It never occurred to me that the terminal has a battery in it. I'll be carefully discharging the CRT and the capacitors and following the same process to hopefully avoid corrosion.
That is so simple and extremely effective
Thank you for the console port settings.
6:33 I wonder if there is an alternative.
On a side note, a friend of mine used the basic idea of the Gigatron TTL computer to build a tiny control CPU for his FPGA RAID-Controller. Works like a charm as a little control CPU.
I never had much luck with the first 68000 it was kind of a slowpoke. What I did like was Motorola's decoupling of the DSP so you could run some things fast on a slow system. I used to run NeXT machines at work (the 040-33 mono slab was the best one) and really liked those until I discovered PA-RISC, which runs the same OS+software. I also kinda like the 68332 Motorola made a "credit card computer" engineering product out of that it was just stellar. I think nowadays the most fun way of doing all this would be to pair a CPU with a FPGA supported by open-source tools. By going that route you can build all kinds of two-chip solutions using vintage electronics... no need for high chip count anymore. I mean before the pandemic you could get SRAMs for free practically but now golly- I think if you have the original CPU and an FGPA then it's enough. Put another way if you're going to make a 68000 board then y'know that chip's appeal is really just the novelty of its form-factor... so nice maybe to pair it up next to a big honking brushed metal Xilinx part from 2013 or so!
In the mid 80s my neighbor wat a wwii vet and he said the g meant government and that no warranty was honored. But he also said that was if it was owned by the government and if a citizen owned it that they would honor a warranty but when he traded in or had one fixed it was 20 years after the war was over so time might habe been why they did. I know they do now because my brother got some old tools fixed for free and a couple swapped for new and it all had the g.
"G" stood for "Government crooks"
Snap-on specifically made tools for the government. I have a set of what you would think our quarter inch ratchets but they’re actually 9/32. They’re close to quarter inch but the socket won’t go on. Apparently they did this so people wouldn’t steal them take them home because nothing at home would work with them
That looks absolutely terrifying, but also very interesting!
Best breaker bar I’ve ever had….put a 2 foot pipe on it and very few things wouldn’t come loose
It actually means industrial finished (non chrome ). Any military tool had a different number associated with it
Depends on the date of the tool. G was indeed a government tool stamp. Some places online also claim it's a date code which is also accurate depending on the tool and location. Notice that the G stamped into my tool is NOT cast into it. It's a stamp which does not match the rest of the tools' normal date code information.
Yes, as a former snap on dealer, G is gov't sold tool....dealers are not supposed to repair them only take & replace with new tool. G was stamped on those from factory....but i never did, i would do the best i could to repair it.
At this point if you have one most snap on guys are going to fix it because its so old best way to keep a customer is to fix his old ratchet
@@sqike001ton facts
What germanium diodes did you use? I can’t find the info. about that! Thanks!
@@burntsemiconductor Thank you!
And still working 😂
I had an odd looking snap on ratchet and the snap on dude wouldn't fix it for me
Trawling ≠ Trolling. Either I'm witnessing a change in words people use for reasons, or I'm being trolled myself.
I’m pretty sure they said Trawling, you just misinterpreted because of how he said it
Yeah I speak a combination of Okie,Texan and Ozarks. Sorry about that. Lol
This is a cool project but it seems like it’s abandoned. The website says they aren’t making any more kits. Also, the Tindie seller isn’t shipping to Canada?
Interesting, this happens with open source projects from time to time. Looks like they still have kits on tindie as of this posting. Good news is the Gerber files and full BOM are out there so technically anyone could build these, even without the kit. Sadly this is the same thing that happened with the little Rosco m68k kit I built and made a video on as well.
While the war department did force companies to provide equipment and machinery, they paid for it. They did not just come in and take tools from snap-on by force. All of it was done under contract and with fair compensation.
Which version of the rim are you using? The GitHub has version 6.
The ROM? The sticker says V6.
Imagine if this was released in 1978.
All i heard was the government steals your shit.
That is one truth that has never changed.
still a thing after soo many years? a good way to recall the designer
Always down for more cool projects if you or anyone here in the comments wants to fire me some more links. Building these is really my Zen time.
Is it a stolen military rachet? I had some wrenches the snapon guy refused to replace because it was "stolen"
G was a a Snapon stamp for “government” hand tools. Former Snapon dealer here, but you can also look up SnapOn’s date code chart and it will tell you all about when your tools were made. Similar to a mint marking.
So where do I find this date code chart so I can Check up on a couple of the old SNAP ON tools I have?
Here you go brother; letmegooglethat.com/?q=snap+on+date+code+table+image
@@burntsemiconductor thanks tons! I got me a sweet deal on tools a couple summers ago. Posted a video on my channel about it. I'd share the link but the comment would probably be removed. It is called auction sale bargain ferro rod giveaway. 85$ for the whole pile.
Post the link man, I won't remove it. Your channel looks nice btw ;-) Pretty rare I don't follow many Kiwi channels.
@@burntsemiconductor will do! Canadian but a bunch of kiwi stuff from a trip last year. Here's the tool buy link. Ever heard of John Deere wrenches? I hadn't. ruclips.net/video/W3hAxEVOjrA/видео.html
The tool nerd comment got you a subscriber
I don't believe the government just took the tools. They bought all the tools. That probably made Snap-on very happy.
Dope , thanks for the history brother.
Cool project
I got that same one. 1/2” drive
Mine are stamped T.e. I think it means too expensive
G stands for "Guarantee forever"
Snap-on refused to honor warranties on tools too many times so now I won't buy anything from them.
G indicates purchased under government contract
When I went to Job Corps in the late nineties the tools we got from the local Air Force Base even if they were Snap-on they were not warrantied because the military used them and they had a certain number on them that they knew were for military use😂
I have that wrench ?? ... by the comments I'm guessing it's worthless
Not at all! Its a bit of history. You can get a rebuild kit for it worst case if needed. They dont make em` like the used to man. If you have one give it some love and clean it up.
So the government that bought planes from boeing, ground support vehicles from Oshkosh decided to take tools from snap on by force? The last year of ww2 saw the military spend 40% of the us gdp, adjusted for onflation the war effort cost 4 trillion dollars. I don't buy it that they just rollec up ro snappn snd says Uncle Sam needs your tools and were not paying for them. I belive the snappn probably had a cobtract to supply tools to the government for a price sure.
Unrelated but I know Disney was pissed about how the DPA took over his studio. I think it would be very possible there were some ruffled feathers as uncle sam made demands of private industry. Now, as far as folks running around with stamps before a bunch of G men show up? Its the story I was told and I don't feel right changing it even if I think it sounds silly. But I agree insofar as I am sure they were very aware of the demand and hand plenty of time to plan. As far as just compensation, during the war everything was saved- no cars were made, bacon grease was literally saved for ammunition production.- I cannot imagine things were easy for a critical industry like a tool maker to get resources- let alone profit. Would really love to hear from a company historian if Snap-On has one. It would kick ass to hear about how this all went down and what it was like to work there if there are any written or recorded interviews from folks working there during the war. Also fun WW2 story? Being from the Tulsa area, did you know that ZEBCO reels you use for fishing came from the ZEro hour-Bomb-COmpany? After the war, can you imagine being like "Well, people don't need bombs anymore. Time to go fishing."
The g for government sure they give you rebuild kit but wait until they no longer have a kit to fit it they won’t replace it with a new one.
I've never seen snapon refuse to warranty a hand tool, even some my brother had that were made in mexico.... Yes they were, snapon sources their production in the country where they sell them, these tools were acquired from a retired master mechanic from a ford plant in mexico.
I have the same exact ratchet. I also have a Craftsman build identical.
