Welcome back, Mike Harrison (@mikelectricstuf)
- Mike is in Belgrade with Chris, both attended and gave talks at Hackaday Belgrade (will be posted eventually)
- Mike gave a talk about the Eidophor
- They will also both attend Resonate.io but neither will speak.
- The fun continues in the UK!
- April 19th – Beer and electronics meetup! We’ll be at the Yorkshire Gray on Theobalds Rd starting at 6:30.
- April 20th – “Nerd Nite” event
- April 21st – There is an Open Source Hardware Users Group meeting.
- Mike recommends learning (uppercase) cyrillic to help get around places like Serbia or Russia.
- Consulting projects continue to get more interesting, you can see them on whitewing.co.uk
- There is a new project that was installed in terminal 2 of Heathrow airport
- Holiday decorations in Hong Kong
- There was a fixture to program physical locations of the assembled PCBs.
- All high level comm was done using RS485.
- Selfridges on Oxford St
- Mike saved the setup time by starting a truck using a drill battery.
- Uses the APA102.
- Test jigs are critical in field jobs, especially time critical ones like busy installs.
- Trade shows for other industries
- Mike went to one for wearable tech, ended up going to underwater exploration instead.
- Saw the company that makes the underwater buoy that Mike tore down. (Sonardyne)
- Museums
- Tesla museum was underwhelming, but Mike saw the first ever radio boat.
- Chris and Mike went to the science museum together and saw the Galaksija (previous guest Voja Antonic’s design)
- Devices
- Mike has been designing devices using loads of 0402 white LEDs. He also gets $0.01 4mm LEDs on aliexpress.
- Osram Duris E
- Reverse engineering
- Mike has experience reprogramming analog(ue) phones. This was done by modifying or moving the ESN of a device.
- The Sony D50 service manual that Dave tore down had a great service manual. Some of the old phones used to have those, but they were hard to get.
- The eeproms were something like 9346
- Mike had to write disassemblers and then read the output to figure out what was going on. He also ended up tracing program flow using a logic analyzer
- Vodaphone had prepaid phones, others were not well implemented and ended up giving away free calls.
- Mike ended up emulating the Dallas UID chips with a small board in order to reprogram the ESN.
- The last time Mike was on an Amp Hour episode he talked about using PICs.
- Write the bootloader first…and make sure it’s rock solid!

Blimey an exponential curve of interesting talk in the history of the life of Mike.
So, you will not be in Belgrade for technology fair? 🙁

Another good show. Is the Dave still on holidays?
It would be cool if Dave and Chris could interview someone from Russia.
Stay tuned! 😉
The stories of reverse engineering were fantastic. More please!
indeed, i am an early 80 child, would have loved to be born 10 years before that, to get all those fantastic times of analog techniques with possibilities to make money from, that sounds just amazing, of course some work involved 🙂
But nowadays, all integrated, only easy way would be software, or internet of things or connected smart industry, and we all know where these bullshit bingos come from 🙂
This is fallacy. Every generation has people longing for the ‘good old times’ and complaining about lack of opportunities.
Today is the GREATEST time to start something new. Apps, cheap hardware platforms, easy access to all the knowledge you would ever need. That ‘iot bullshit’ will become as ubiquitous as cellphones or wifi in the nineties.
Do you really think people in the nineties went ‘wifi is the future, lets invest in that’? Here is a reality check https://www.youtube.com/watch?v=Tj5NNxVwNwQ
Great show! Mike is an amazing guest 🙂
wow Mike, you dodgy F…
Few more interviews and we will learn you came up with first playstation mod (pic 12C508) ;o)
