 +Another strong attendance at this meeting, the fifth in the yearlong series, **“CBUS from Soup to Nuts”**, heard about **three different approaches to control panels**. 
 +  
 +**<color #00a2e8> Mike Plowman </​color>​** kicked off with a simple panel using Veroboard to eliminate individual wires to the LED’s and switches. Mike explained the use of Microsoft Word ® to create the track plan on a one tenth grid to match the hole pattern of the Veroboard. Although the example was a small panel, the same technique had been used on the large control panel of Kineton, the LWMRS N gauge exhibition layout. 
 + 
 +**<color #00a2e8> Simon West </​color>​** showed how the two control panels on the LWMRS 00-gauge layout, Duxbury, had been developed. The main panel, which is four feet across, allows two operators to simultaneously change points or set routes. This led Simon to explain the importance of diodes in the push button matrix circuit. He showed how matrices of the CANPAN, CANLED64 and CANACE3 are structured and how back of panel wiring is simplified. 
 + 
 +{{:​public:​1_group_view.jpg?​400 |}} 
 +Finally, **<color #00a2e8> John Gowers </​color>​** showed how he developed panels for his garden railway from early plywood prototypes through to custom PCB designed using Eagle ®. John discussed the changes which have been implemented in the manner of control of the LWMRS 0-gauge exhibition layout Kimble. The six operators use MERG CABs to control the locos and with the need to drive to the signals, the operators need to have accurate indication of loco position when approaching a signal provided on a small indication panel next to the operator position. He also discussed plans for future developments. 
 + 
 +The main event in the afternoon workshops was the demonstration by Simon West and then a hands-on session for members of writing firmware using the PICKit 3. Simon recommended the use of the ZIF socket method to write the firmware and using this, Simon was able to show how easy and straight forward the process is using the correct tools. 
 + 
 +**<color #00a2e8> Mike Collins </​color>​** ​ brought part of his home layout for advice regarding the implementation of CANMIO Universal firmware to operate a mixture of servos and relays. An interesting discussion involving several members enabled Mike to make significant progress.
