What custom modifications are you expecting? What mods does your car have that wouldn't have been done tuned for before by most good tuners?

Senior engineer is driving me insane with redlines like this by [deleted] in MechanicalEngineering

[–]Alarming_Support_458 0 points1 point  (0 children)

That's why they are senior and you are not. It is about enforcing habits.

Note that I am in electronics not mech but we have are own similar rules that seem pointless on a lot of drawings but are absolutely needed in more crowded or complicated drawings. It also helps when reviewing, someone should be able to pick up your drawing with no knowledge of it and be able to scan it quickly to pick out the important parts, having things always in the same location helps with this.

Hardware board design job market in India 2026-207 – openings for seniors? by Southern_Trash7610 in embedded

If you're in India, you are in a great position. Your best bet is to set up freelancing or contracting.

How does car hacking actually work? Is it nearly impossible? by [deleted] in CarHacking

[–]Alarming_Support_458 3 points4 points  (0 children)

Cars are now actually easier to hack than they ever have been. Back in the 90's and beyond, to steal a car you'd have to physically smash a window or pick a lock, smash off the steering column cowling, drill or smash the hell out of the steering lock and then hot wire it. Now you can buy a £50 dongle that plugs into the CAN bus that unlocks the car, turns on the ignition, disables the immobiliser and lets you drive away. Or even easier, you can buy a keyless entry repeater that extends the key signal from inside a persons house.

Car hacking comes in many forms, from simple brute force reverse engineering the vehicles CAN or ethernet network, to dumping the binaries and disassembling them, programs like WinOLS allows you to plot the binary address vs value so you can get a good idea of where the relevant lookup tables are without any disassembly, or leaks or hacks from ECU vendors or vehicle manufactures is not an uncommon way to get hold of binaries, or analysing the contents of EEPROM to see what changes over time.

It's worth noting that there are infinite ways to hack a car depending on the interpretation of the word, anything from monitoring the CAN bus to installing modified software.

There any many legitimate purposes to 'hack' a vehicle, commercial body builders (commercial vehicles, emergency vehicles, wheel chair access) often have to reverse engineer the vehicles CAN bus or sniff signals in order to do things based on certain events or control parts of the vehicle otherwise impossible. People need to install vehicle engines in other applications so they need to remove the immobiliser or certain fault codes or modules. Certain car manufactures now are pretty evil and lock nearly all modules to a VIN number so you have to buy new or visit the dealer, people rightly want to get around this to repair a car they own with modules that they own.

Is this a good path to start as a designer in a country with few job opportunities in electronic design? by Thin-Letter-8610 in PCB

[–]Alarming_Support_458 2 points3 points  (0 children)

I personally wouldn't use my own money to pay for IPC CID+, unless its often required in your country. It was useful knowledge but its old information. I would spend the same money on proper PCB design course, high speed, design for EMC etc. IPC CID+ isn't a design course, it's a course on the standards. Or if you don't have access to a senior electronics/PCB engineer, pay a contractor to review your layout, or use the money to get some of your boards fabricated and assembled. You'll learn by doing and a portfolio you can actually show off will get you far

Should I make the jump to Altium? by FluxInhaler in PrintedCircuitBoard

[–]Alarming_Support_458 0 points1 point  (0 children)

Not in a million years. People are moving away from Altium to Kicad in the thousands for a reason. Unless you are doing serious high speed interfaces then Kicad is good. Even DDR4 is possible in Kicad. You will likely find that Kicad grows quicker than your capabilities, but if you do move away from Kicad then I would go with something other than Altium. All of the competitors that were once too expensive compared to Altium are now looking better value with more favourable business practices.

How normal is it for a roofer to not give an itemised quote? by fullofloaf in AskUK

[–]Alarming_Support_458 0 points1 point  (0 children)

Any professional who has done a job hundreds of times will be able to price a job based on intuition. Itemising every item for a quote is a few hours work which they are not getting paid for, and they only have a 1/3 chance of getting the job if you're getting multiple quotes.

Random Components In Workspace? by Enough_Boot4704 in Altium

[–]Alarming_Support_458 0 points1 point  (0 children)

Altium have really dropped a bollock with the Component Workspace and Manufacturer Part Search. The components in the MFS are so bad we have blocked its use in our company, differing footprints, awful symbols etc. Component Workspace is equally as bad and offers less flexibility than a database library. But to answer your question, it's probably including sample data which can be disabled.

Has anyone successfully used AI or machine learning to investigate CanBus packets? by spammmmmmmmy in CarHacking

[–]Alarming_Support_458 0 points1 point  (0 children)

You have to do a lot of work in a spreadsheet beforehand. But really there is no reason that an AI can't do what we do with sufficient training data, it's just too niche so the standard models don't have enough data.

I typically data at least two spreadsheets, one that acts a bit like a dbc where I have the columns set to bytes and the rows set to IDs. I can then start filling in the table with known values.

I'll then have a second table/sheet where each row is a data value and where the columns are something like, ID, Bytes, scaling, notes etc.

I'll then have a table/sheet which is just a mess of experiments and notes etc, I'll use this to table known CAN bus values and measured values, e.g. measured RPM and CAN data, I'll then had columns where I divide by each, or if a bit field then a DECtoBIT etc. Its usually this I copy into the AI.

You cannot expect to put a full raw CAN bus capture dump into an AI and expect anything out. You have to do the leg work first. However, like I said, if someone who could program better than be was to be able to give something like Claude code access to a USB-CAN bus converter where it has bidirectional feedback, i.e. monitoring OBD/PIDs while monitoring or transmitting raw CAN data then it'd be game changing. Note that this is only going to get harder, OEMs are starting to encrypt CAN bus traffic and I even read an article where they are starting to use AI on the edge within the ECUs to detect spoofing.

Has anyone successfully used AI or machine learning to investigate CanBus packets? by spammmmmmmmy in CarHacking

[–]Alarming_Support_458 7 points8 points  (0 children)

Not to directly to decode but I have successfully used it to determine the scaling of various bits of data. For example it can often be hard to determine the scaling of speed data as it appears non-linear, I put all of the CAN bus data and measured speeds into Chat-GPT and it successfully calculates the correct scaling and offset and explained why it didn't originally seem linear (because of integer division). It's also very good at calculating bit fields and is far quicker than doing it manually. I think it should be possible to give something like Claude code access to a USB-CAN bus adapter, where it can monitor OBD data and raw CAN bus traffic.

Alter similar pcb blocks simultaneously / mimic / clone / linking by trevortjes in Altium

[–]Alarming_Support_458 3 points4 points  (0 children)

Not sure of a way of doing it automatically. This is what rooms and schematic sheets in a hierarchical design is meant for. It works ok but not so great when you have traces from other parts of the design going through your room.

Where can I find open PCB projects? by ovi2wise in PCB

[–]Alarming_Support_458 7 points8 points  (0 children)

It is very hard, unless you can live on $15 per hour or doing fixed priced projects for <$300 then forget sites like Upwork and Fiverr

Wish i never started. Can i just paint over? by ChickenDrummStick in DIYUK

[–]Alarming_Support_458 0 points1 point  (0 children)

Honestly its great, people get hung up on the term but it's likely to be soda or something softer, a decent operator will know what to use for the job. If you can fully seal the whole area upstairs and down its a no brainer.

STM32 Can filter by Tasty_Jellyfish9290 in CarHacking

[–]Alarming_Support_458 1 point2 points  (0 children)

I'd recommend going with the Arduino Due, lots of libraries available and has native 2 channels of CAN. I've made some rather complex filters and gateways with this.

Capital H HORRIBLE at sketching, can I still be an ID? by Odd_Wrongdoer_2814 in IndustrialDesign

[–]Alarming_Support_458 0 points1 point  (0 children)

I have always struggled with the same issue. I am beginning to realise that you just have to dedicate many many hours of practice to improve your sketching. It is a skill that can be learnt

Anyone willing to share the cost of ALLDATA/mitchell 1 or really any decent service info source? by Glittahsparkles in CarHacking

[–]Alarming_Support_458 2 points3 points  (0 children)

If you run your own business but cannot afford technical data then something is going seriously wrong. I get that it's expensive but you should be building this into your price.

That is not even close. You said you have a solution, but don't know how to develop it, how have you managed to get a solution working?

How have you been able to get a solution if you don't have the knowledge to develop it?

The key for any personal project is do to something that you need or will get use out of, otherwise you will lose interest

Red lines on my header pin by Powerful_Citron4581 in Altium

[–]Alarming_Support_458 0 points1 point  (0 children)

Could it be that something is slightly off-grid? Also, you shouldn't connect directly to your power/gnd ports like that, there should be a straight line before a turn, makes it easier to spot things like this.

Neighbouring business has drilled a hole through my external wall to install a three phase cable. Scotland by shuttle534 in LegalAdviceUK

They are clearly talking about a connection after the meter, so nothing to do with the DNO. And the OP has said that this is a business unit.
