Project XG Errata

Stop Press

ProjectXG Due to the complexity of the September issue Project XG feature, unfortunately some mistakes would crept into the DIY feature. We can only apologise and include the necessary addendums here.

It seems that Figure 3 on page 25 contains a number of errors. These include; inline resistors from the Amiga audio input which are not included in the current design. No pin numbers on the DB50XG header for the audio outputs. The indicated wires are wrong anyway. The 25D and the 23D are incorrectly labelled pin wise. Please refer to this correct diagram.

We left the Maplin MPS' contacts out of the order form in the Project XG feature. Oops! Also, the Dual 10K log pot is indeed £1.19 so don't be concerned with the incorrect Unit Price. The case is also incorrectly specified in the parts list. The correct part is 'LH51' and not 'YN40T' as stated in the parts list. It also costs £4.58. You can also make the DB50XG fit the incorrectly specified box by cutting off the corner posts and using long screws to attach the lid. Maplin's details are as follows;

Figure 3a
On page 27 the instructions incorrectly refer to the 4K7 resistors attached to the Amiga audio input RCA sockets. The same resistors that are also incorrectly shown in Figure 3. D.I.Y. The resistors should actually go from the DB50XG header to the 10K log pot as per the diagram above and the circuit diagram on page 27 also. Please note the correct pins on the DB50XG header for the audio contacts, there will be a row of 5 connected pins numbered evenly from 26 through to 18. It will have reset on 26, Right audio on 24, -12V on 22, Left audio on 20 and +12V on 18. For this reason, it's vital to get the audio and power pins 100% correct.

Our apologies for the inconvienience. We found that Project XG has served as a valuable learning experience and our future features in the regular DIY Scene section will be more clear, easier to construct and yet every bit as amazing as Project XG. E-mail us if you should have a problem.
