Great Product!

For Simple EEPROM Programmer shield for Arduino Mega

I purchased the PCB only as I already had all the other components. After about half an hour, the programmer board was sitting on top of the Arduino Mega 2560 board, ready to be "played with". A brand new Atmel AT28C256-15PV was inserted into the ZIF socket and, using the designer's Windows app to read/write EEPROMs (eewriter), all the operations were tested - read, write, and verify.

Eventually I have downloaded the ROM image I was interested in, uploaded to the ROM, and verified it - all went very smooth. Now I am waitng for one more component to complete my Harlequin 48K ZX Spectrum clone.

Thank you for a great product!

Very useful little board

For Simple EEPROM Programmer shield for Arduino Mega

Very useful little board - much better than messing around with a breadboard and loads of DuPont jumpers (and no chance of wiring it up incorrectly, either). Easy to quickly pop on or off when you need it.
Straightforward to solder, and the Arduino sketch works fine - I’m using an amended version of the python client, as I’m using a Mac, and it all works great.
Have a few Chinese AT28C256’s which appear to have the software protection on, and the Arduino code doesn’t unlock them, but I think it did work unlocking another EEPROM, so I think that’s a lack of consistency on the EEPROM side.
Much cheaper than buying a dedicated EEPROM programmer

A easy build and a great little kit. Worked first time!

For Simple EEPROM Programmer shield for Arduino Mega

I just bought the bare PCB because I had all the other parts in my spares box. An easy build that worked first time. I used it to burn a new kernal ROM onto a AT28C64B EEPROM for a VIC-20. Wrote and verified the ROM first time, and worked great in the VIC when paired with a Open2327RomAdapter.

Thanks for a wonderfully useful and value for money item!

very usefull programmer and economical.would recomend it.

For Simple EEPROM Programmer shield for Arduino Mega

I built this and it works great.just need to set the eeprom size in the menu.play around with it and its fine .i also put non volatile 32k ram the kind with the built i battery.and it read it ok.very usefull

Good board

For Simple EEPROM Programmer shield for Arduino Mega

I had been having difficulties building my own similar device from scratch, and this board gave me the kick start to write the Arduino code and PC code to make it all work. I haven't much tried the Arduino code provided, but I did use it and the provided paper documentation as reference for writing my own.

Learnt a lot because of this, thanks

Order #241308 Received

For Simple EEPROM Programmer shield for Arduino Mega

Hello, I received the item yesterday. The contents were pretty and delightful, I really do commend you on your creativity and attention to detail. I am waiting for my socket and resistors to arrive from China now.

I tried sending you this info via the contact button, but Tindie's contact feature seems to be broken.

Cheers :-)

What a cracking little tool.

For Simple EEPROM Programmer shield for Arduino Mega

Nice PCB. Easy to put together. Great documentation.
Successfully reading and writing EEPROMs with the associated software. Very happy.

Very simple and effective

For Simple EEPROM Programmer shield for Arduino Mega

It took less than half an hour to solder the components together and it worked "out of the box" to read/write an Atmel 28C256 EEPROM using the 0,2 version of the Arduino sketch. I used the "gui" version of eewriter without any problems. Excellent piece of kit! Thank you very much!

Good bit of kit!

For Simple EEPROM Programmer shield for Arduino Mega

I spent ages trying to make my own one of these on veroboard with little to no success. Turns out it was much less effort to just buy this 😆

I think the included software only worked with windows 64 bit though, I tried to use it with an old 32 bit eeepc I use for all my car stuff. If it was just a case of clicking a compile check box it would be nice to have a 32 bit option.

Apart from that it was very quick, I managed to read all my car eproms in about 15 minutes!

Great quality product and very fast shipping!

For Simple EEPROM Programmer shield for Arduino Mega

Great quality kit, PCB, and ZIF socket! All components included. The instructions were very easy to follow and a nice schematic is included too. I've been using the "Simple EEPROM Writer" GUI software without any issues on my AT28C256 EEPROM for my 6502 computer project.
On top of that, even with all that's going now in the world, the kit took only 11 days to arrive from England to Canada!

Only thing is I wish there was a GUI option for macOS too but maybe one day in the future...

Thanks for making this available!

Programmer shield for Arduino Mega to read 27C256 or 27C512

For Simple EEPROM Programmer shield for Arduino Mega

Dear Sirs,

I needed "Simple EEPROM Programmer shield for Arduino Mega",
even it was designed for 28c64, 28c128, 28c256, and so series eproms.

I had problems to read AMD27C512@DIP28 chips with my other
programmer, which claimed that those chips were all faulty
and thus unreadable.

I edited eeprom-write_0.02.zip program.

a version for chips TMS27C256@DIP28 to test the programmer read option.

and another version for chips AMD27C512@DIP28, which was my final goal.

And I was really able to read AMD chips.
The only changes was to remap the address lines - just a little bit.

My basic idea was that I could (maybe) easyly change the read-out timing signal,
but that was unnecessary.

cheers rauno lauhakangas

Great little kit

For GPS-Controlled Binary Clock Kit

A great little kit, perfect for occupying a rainy night at home.

The documentation is thorough and easily followed, the PCB is good quality.

Keep up the good work!

Fantastic bit of kit, ideal for geeks everwhere

For GPS-Controlled Binary Clock Kit

I first saw this clock demoed at a recent Tindie / Hackaday Beer and Hacks meetup in Nottingham, and it caught my attention straight away.

The LEDs used on the demo were a bit bright for my liking, so I ordered a kit using Red, Orange and Yellow LEDs (Blue is a bit bright for my liking).

The instructions supplied are very good, and accurately show how to build and use the clock.

I had no problems building it and getting it running, and only took me around 1.5 hours from start to finish. I am quite expedience at building circuits, so would expect it to take a bit longer for less experienced solderers / beginners.

The kit only uses through-hole components, so is very suitable for beginners, and even included a couple of spare parts (just in case they get lost while assembling?)

My main concern about the GPS based clock was if it would be able to receive GPS signals indoors. The instructions and notes do help explain this, and say that a full GPS lock is not required to obtain the time. So even if just 1 satellite is receivable, the time is available.

It did take around 15 minutes to establish the correct time the first time I powered it on, this may just be due to satellite locations, etc.

Overall, I'm very pleased with it, and wouldn't hesitate to recommend others to buy this. It's a great talking point, and tells the time to boot.

It was a well designed kit.

For Simple EEPROM Programmer shield for Arduino Mega

I got distracted and didn't get it built for almost two weeks. It was well designed. I would have liked to see a schematic just because I always like to see one. Good job, keep then coming.

A nicely present kit with great support

For Simple EEPROM Programmer shield for Arduino Mega

Very nicely present kit, good instructions and easy to assemble. Great support from the creator who helped me deal with an issue that was down to the chips I was using having been locked by another EPROM programmer, now resolved with a code update.
