Nice project and presentation.

the parts are expensive now this will cost about 50.00 bucks to build or more. and you have to build it.
if you have most of the parts laying around or good at scrounging then it can be cheap.
i had the keypads and lock ic's all ready, the lock ic's where 1.50 ea. now like 12 bucks ea.
and making the traces for the 4 dips is complacated.
so iam going to use a RFID keypad or a CL-8 keypad, these are eprom programable from the keypad and the CL-8 is about 52.00 brand new and the
RFID is like 14.00 on ebay. brand new

i bid on the CL-8 on ebay if won it wood be 21.00 dollars used, so i bought the RFID for 14.98 it comes with 10 key fobs
i will be adding the transmitter to this one,the nice thing about this one is you can just swip the key fob or use a passcode, i will be installing this one in the house and setting D/W sensor to max. my DS7000 came with 4 key chain remotes so this one will only cost 14.98 plus some labor much better on  the pocket book.

it is sad when it costs more to build then to just buy somthing
most of the fun is buildding somthing from scratch and a sence of acompleshment.
but i need one now so i will keep this quick and simple for thoughs that need one soon for kid access.

I can remember all the HeatKits I built.
Actually cost more manytimes than a mass produced one.
Though you knew they where built correct and didn't have low ball parts in them.

Oh HeathKit...where did you go......?
Boy do I miss them. Would love to have another shot at my HW-101 (ham radio).
Oh, and that weather station too.
anyway...sorry about the $.02

ya that was when hams where hams could tweek and peak your radio and add all the freeks sorry about my 70's slang haha
loved all the heathkit radio kits.

As long as we are paying homage, don't forget Allied Radio in Chicago with their "Knightkit" kits. I loved my Knightkit Shortwave receiver. But I was about 12 when I built mine....with a Weller soldering gun...sigh. I had to take it to the local TV repair shop to get it working. Undoubtedly a solder short on the 6L6 socket.

Sweet, is that a tube type? looks like it.

Sweet, is that a tube type? looks like it.

Oh yes, early 1960's. I think it had seven tubes, and none of them were 6L6's

here is the Transmitter Mod. I ran the 2 wires from the dis-arm to a 12v Reed Relay mounted on a small pice of perf board.
