Here are some of the new products I'm working on.

Expanded DC Voltmeter

This first one up is a expanded DC voltmeter. This meter will display a standard 12 V dc power supply or battery from the range of 10 V dc to 15 V dc.

While shown with a meter,
the meter will NOT be included in the kit. It's a standard 85C1 meter from eBay.

The kit will include the pcb and all pcb mounted parts as well as a printed meter face for you to install. It's not hard and takes about a half an hour.

The price will be $18 for the kit.

New Micro P solar charge controller

Stacks Image 783
This is the New Micro P solar charge controller. It will control 15 amps and produces NO RFI doing so.

The heatsink shown will not be included. I had a few of these laying around and mounted the this pcb to it.

The Micro P has terminals to connect the battery and solar panel.

There is also a low voltage warning system for the battery.

Price about $45 in kit form.

I have a limited number of prototype pcbs available for $12 plus shipping. These are for an advanced builder. You'll get a schematic and pcb overlay only. No manual.

Heathkit SB-200 Power Supply Upgrade

Stacks Image 798
After many requests for a power supply upgrade for the Heathkit SB-200, one has been designed and is going though testing. Like all the other upgrades, only the best pcbs and parts are used.


About $125 in kit form.

I have only a handful of prototype pcbs. There are two errors. One is a missing connection. The red jumper is shown connecting the two halves of the voltage doubler. The other mistake is a missing pcb pad. The black wire is shown making that connection. The PCBs work, and will fit inside the SB-200 like a glove.

There are no instructions, only a schematic and part overlay.

Again, these are prototypes and are sold at a reduced price. Only four are left at this time.

Remote four position antenna switch

This four position antenna switch uses two high current relays in series to provide outstanding isolation between ports.
