The mircrosoft windows editor diary

The windows editor can do a few things more than just writing plain text. When you write .LOG in the first line and save as *.txt, on the next startup the editor inserts an timestamp.

DIY – The cheapest dual trace scope in the galaxy

It has 2 analog inputs and can supply 5V ont the 4 pins header on the right. One of the inputs can be scaled down with the trim pot.
The firmware in the Tiny45 is written in C and compiled with Winavr and usb source code from obdev. As you can see, there is no crystal , the software sync the internal 16.5Mhz pll clock with the USB clock.

The cost with a home made pcb is around 5€.
Of course, do not expect 1Gs/s HID does not alow that data rate !
But it is using a 10bits AD.“

DIY Apple I clone – replica I

For those who’re to young for an original apple bought in the shop, here is the ultimative chance to get their own one

The replica 1 is a functional clone of the apple 1 computer created by Steve Wozniak in 1976. This was the computer that Steve Jobs and Woz used to start Apple Computers in 1976. The latest version of the replica 1 is labeled SE for Second Edition. The replica 1 functions exactly like the apple 1 with many of the same components like a 6502 CPU and 6821 PIA. It comes with 32K RAM and 8K EEPROM. Addtional features like a ps/2 port, serial, USB port, ATX and DC wall power supply connectors makes the replica 1 a fully functional computer system for todays collector or hobby builder. Available as a kit or assembled, the replica 1 is sure to give you hours of fun and excitement as you relive the glory days of computing. As a new feature, a full blown assembler called Krusader written by Ken Wessen was added to the EPROM space giving the user the ability to assembler 6502 programs right on the replica 1 without a PC. Write 6502 machine code programs using mnemonics instead of just programming hex code into the memory. This added programming tool makes the repica 1 not only a nostalgic computer but a great learning tool and introduction to microprocessors.“

Or the non-hardware alternative, the apple I emulator:

„Pom1 is an Apple 1 emulator and is being ported to C from the original Java version. It uses the Simple DirectMedia Layer library and works on most platforms“

Travelling to india 2nd try

The first try to travel to India in December 2008 wasn’t successful, because of the event of terrorist attacks. For our own safety we decided not to fly, the alternative was a nice and enjoyable trip to Singapore, Malaysia and Cambodia.  A few things need more than one try, so we booked tickets for October 2009 again. We hope that nothing unusual happens. On the plus side, we know the address of the embassy in Hamburg this time. It will be my first flight with THY – Turkish Airlines, because they had a excellent offer via opodo.de.

Connecting a Bronkhorst MV-306 via RS232

Connecting a Bronkhorst MV-306 via RS232 to the computer is a easy thing, when you don’t forget to set the rs232 signal ground to ground. All you’ve to do is connect PIN 2 (RxD Receive Data), PIN 3 (TxD Transmit Data) and PIN 5 (Signal Ground) with the Pins of the MV-306. The pinout of the MV-306 is 1 Tx-RS232, 6 Rx-RS232 and PIN 4 and 8 are ground.

Use this setup and the things works just fine:

RS232 PIN 2  <–RxD–> MV-306 PIN 4

RS232 PIN 3 <–TxD–> MV-306 PIN 1

RS232 PIN 5 <–Ground–> MV-306 PIN 4,8

This works right for me, i’m not responsable for any damage happens to you or your equipment.
