Well, I came home last night to a porch overflowing with parcels (I’m quite the net shopper). And what a load of goodies for me. My laptop finally came in. It’s an IBM X20 with all the trimmings. It’s light with high build quality and the best laptop keyboard I’ve ever used. I like it.

My CO₂ injection system and pH controller also arrived. I had fun hooking it up to my testbed aquarium. With the pressurized C0₂ canister, bubble counter, and reaction chamber not to mention the canister filter, temperature probe, pH monitor and probe, and all the tubing and plumbing which ties it all together, the back of this aquarium looks like a cyborg jumble sale.
