Just finished assembling the last units from regular production. If you have not heard from me, you will have to wait for a small extra production run that I am scheduling. I should be able to satisfy the current waiting list.
One special rebuild is remaining, I will take that to the Allschwil meeting. Last week I have tested an improvement, which is a relatively simple modification. This allows a goldcap (if it is installed) to be charged from USB instead of from the HP41. This saves battery power and allows the unit to be connected to USB for recharging. The standard cap built into the assembled units has a value of 0.1F, and keeps the SRAM contents alive for a few week. I have also tested a 1F supercap and that works fine as well.
Another addition is to pimp your MLDL2000 and add some bling-bling by using some (blue!) LEDs. The LEDs indicate MLDL2000 activity, USB activity and one can be user controlled (but not fully tested yet). To save battery power, these only work when USB is connected, the LEDs are powered from USB. This special version will be shown in Allschwill. Schematics and instructions to be published within a few days.
Looking forward to meeting some of you in Allschwil!
